Wildlife faces threats(威脅)from habitat destruction, pollution, and other human actions. Although protecting wildlife may seem too hard at times, even small actions in your own neighborhood can help protect many different animals. Here are some tips on how to protect wildlife through small actions.
1．Create wildlife friendly areas in your backyard.
When trying to make your garden more beautiful, you can choose plants that can provide food and shelter to native wildlife. This will also help cut down on pollution. And bird or bat houses to your yard or garden to attract and shelter these species.
2．Avoid harming the natural ecosystem(生態系統)in your area.
Some plants from other places can kill or harm native plants that provide food and shelter for wildlife.
3．Have a greener lifestyle.
By using less water and fewer fuels, you will be helping to protect the wildlife around you. Take buses or the subway when you can, turn off electric devices when you're not using them, take shorter showers, and keep your room temperature at or below 68 degrees during the winter.
4．Buy products that are wildlife friendly.
Don't buy products that are made from endangered animals. Keep in mind that some endangered animals are killed by traps, catches or hunters who are after other wildlife within the same habitat.
5．Donate money or time to organizations that protect wildlife and their habitats.
You can give money to organizations or groups that protect wildlife species in your neighborhood.

An astronomer is making a case for launching pop singer Justin Bieber into suborbital（亞軌道的）space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager — he would come back down to Earth eventually, after all — but rather to help jump-start the emerging suborbital spaceflight industry.
It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. “If there’s more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good.”
Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport.
None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z.
Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists — but Shostak is thinking about ways to make it grow.
A celebrity launch isn't Shostak’s only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling（充滿）with cameras both inside and out, to give the public dramatic views of every mission.
Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry’s success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
小題1:Why may Justin Bieber be sent into suborbital space?

A．To show his bravery and make him a role model for teenagers.

B．To arouse the American public’s interest.

C．To help reform the spaceflight industry.

D．To film an advertisement about space.

小題2:What can we learn about suborbital spaceflight?

A．A trip will return to Earth before finishing a lap.

B．The whole trip will leave passengers weightless.

C．Each trip can take 500 passengers.

D．The trip will be too expensive even for celebrities.

小題3:What can we infer from the text?

A．SpaceShipTwo will be the first to fly.

B．Famous people will be the main passengers in the future.

C．The space trip is still in preparation.

D．Every space trip will be made into a film.

小題4:The last paragraph suggests that _________.

A．space is too mysterious to explore

B．the suborbital market is promising

C．the spaceflight industry is more successful than people think

D．developing the industry is risky

小題5:What is the main purpose of the text?

A．To predict a change in the space market.

B．To discuss a recent launch.

C．To introduce the status of the spaceflight industry.

D．To remove public doubt about the spaceflight industry.

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image(形象) of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. "We were surprised by just how positive today's young people seem to be about their families," said one member of the research team. "They're expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There's more negotiation(商議) and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat."
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. "My parents are happy to discuss things with me and willing to listen to me," says 17-years-old Daniel Lazall. " I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with it." Susan Crome, who is now 21, agrees. "Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that."
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, "Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over."
小題1:According to the author, teenage rebellion ________.

A．resulted from changes in families

B．may be a false belief

C．is common nowadays

D．existed only in the 1960s

小題2:What is the passage mainly about?

A．Education in family

B．Negotiation in family

C．Teenage trouble in family

D．Harmony in family

小題3:The study shows that teenagers don't want to ________.

A．go boating with their family

B．share family responsibility

C．make family decisions

D．cause trouble in their families

小題4:What is the popular images of teenagers today?

A．They dislike living with their parents

B．They quarrel a lot with other family members

C．They worry about school

D．They have to be locked in to avoid troubles

小題5:Compared with parents of 30 years ago, today's parents ________.

A．care less about their children's life

B．give their children more freedom

C．go to clubs more often with their children

D．are much stricter with their children

When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction.
Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
小題1:The aim of the extinction of large prehistoric animals is to suggest that _______.

A．large animal were not easy to survive in the changing environment

B．small species survived as large animals disappeared

C．large sea animals may face the same threat today.

D．Slow-growing fish outlive fast-growing ones

小題2:We can infer from Dr Myers and Dr. Worm’s paper that _______.

A．the stock of large predators in some old fisheries has reduced by 90%

B．there are only half as many fisheries are there were 15 years ago

C．the catch sizes in new fisheries are only 20% of the original amount

D．the number of larger predators dropped faster in new fisheries than in the old

小題3:By saying these figures are conservative (line 1, paragraph 3), Dr worm means that_______.

A．fishing technology has improved rapidly

B．then catch-sizes are actually smaller then recorded

C．the marine biomass has suffered a greater loss

D．the date collected so far are out of date.

小題4:Dr Myers and other researchers hold that _______.

A．people should look for a baseline that can’t work for a longer time

B．fisheries should keep the yield below 50% of the biomass

C．the ocean biomass should restore its original level.

D．people should adjust the fishing baseline to changing situation.

小題5:The author seems to be mainly concerned with most fisheries’ _______.

A．management efficiency

B．biomass level

C．catch-size limits

D．technological application.

The human body has hundreds of muscles. The three types are skeletal(骨骼的) muscles, smooth muscles and cardiac, or heart muscles. Each kind of muscle has a special job to do.
The skeletal muscles are attached to the bones; they actually hold the skeleton together. Strong cords, called tendons(肌腱), help connect these muscles to the bones. Skeletal muscles give us strength and allow us to move in many ways. If you look at skeletal muscles through a microscope, you will see that it has bands of fibers that look like stripes(條紋). These stripes are called striations. Skeletal muscles usually move because the brain has sent a conscious message to them telling them what to do. This is called voluntary movement.
Another type of muscle is smooth muscle. Unlike skeletal muscle, smooth muscle does not have striations. This is found in organs such as the stomach, the bladder(膀胱), the lungs and the eyes. Smooth muscles are smaller than the skeletal muscles and they move involuntarily. The brain tells these muscles what to do, but we aren’t even aware of it. For example, we don’t have to think about breathing or digesting food. The smooth muscles just do their jobs automatically. For this reason smooth muscles are sometimes called involuntary muscles.
Like smooth muscle, cardiac muscle also works involuntarily. It is a very thick muscle that is found only in the walls of the heart. Its job is to pump blood out of the heart and into blood vessels called arteries(動脈). The arteries help carry the blood to all parts of the body. When the cardiac muscles relax, they let blood back into the heart. Cardiac muscles have striations, just like skeletal muscles do.
小題1:When we _______, the job is done by smooth muscles.

A．close our eyes

B．kick a ball

C．hug our friends

D．lift a suitcase

小題2:Skeletal muscles and heart muscles are alike because_______.

A．both can move voluntarily

B．both are thick muscles

C．both are bigger than smooth muscles

D．both have stripes called striations

小題3:Which of the following is TRUE according to the passage?

A．Heart muscles are very important because they give us strength and allow us to move.

B．The heart of human beings completely consists of heart muscle.

C．The skeletal muscles are connected to the bones by tendons.

D．Smooth muscle does its work without receiving message from the brain.

閱讀下面短文,并用英語句子回答問題(請注意問題后的字數要求)10分）
Words can hurt
I remember the pain most vividly. My stomach was sick, my heart hurt, and my eyes stung(刺痛的) from holding back tears.

“you know, Autumn,” my friend Nick said, “Lisa and Andrea were just talking about you.” I immediately got nervous. “They said that the only reason you start on the basketball team is because the coach

（教練）likes you .It’s not because you’re good.” I might be sick. “They said they’re tired of you always getting what you want.”

I struggled to keep myself from crying, sinking

（下沉） to my knees on the cold floor. After Nick told me everything my supposed best friends said about me, I was hurt.

Lisa and Andrea came in from lunch break acting as if nothing had happened . Lisa was still my deskmate, and Andrea was still my partner for our history project.

I was amazed at their ability to pretend we had the perfect friendship, especially since they’d said such hurtful things.

I was a freshman in high school, and I felt like I didn’t have a friend in the world, all because of a rumor（謠言）.
The tongue can be our worst enemy. Rumors harm confidence

（信心） and separate close friends. They are like sharp knives, cutting one’s dignity（尊嚴） into pieces. When we say unkind things about others, we’re thrusting(插) knives into their hearts.

So how was I to act next? When Lisa and Andrea pretended our friendship hadn’t changed, I thought of attacking them back. But instead, I told them directly that they had hurt me. Lisa started crying and Andrea was speechless. I know they were both sorry for what they had said. They apologized, and I forgave them with grace(

優雅). Sure, things were a little awkward(尷尬) at first, but soon enough everything was back to the way it had been before.

I still deal with gossip

（流言）, sometimes as a recipient（接受者） and sometimes as a participant（參與者）. But the more I learn about love, the more I realize the importance of encouraging others- sometimes gossip never does.

小題1:What word can exchange the underlined word in para1?

Become a confident speaker. How to improve your English speaking skills and make you able to communicate more easily and effectively? The following tips will help you to become a more confident speaker.
Practice where you can and when you can. And practice is good — whether you speak to someone who is a native English speaker or not.
It’s important to build up your confidence. If possible, use the simple sentence structure that you know is correct, so that you can concentrate on getting your message across.
Try to experiment with the English you know. Apply (應用) words and phrases you know to new situations. Native English speakers are likely to correct you if you use the wrong word. They usually don’t mind if you use wrong grammar.
Try to respond to what people say to you. You can often get clues to what people think by looking at their body language. Respond to them in a natural way.
Never translate everything into your own language. It takes you much time and you’ll find it difficult to find an English answer right away. You don’t know how to do well. The more you want to act well, the more slowly you act. This will make you hesitant.
If you forget a word, do what native English speakers do all the time, and say things that ‘fill’ the conversation. This is better than remaining completely silent. Try using ‘um’, ‘er’, if you forget the word.
Don’t speak too fast! It’s important to use a natural rhythm (節奏) in speaking English, but if you speak too fast it will be difficult for people to understand you.
Try to relax when you speak, and you’ll find that your mouth does most of the pronunciation work for you. Speak English at a normal speed.
Final tips: Try to become less hesitant. Don’t be shy to speak — the more you do it, the more confident you’ll become. Remember to be polite — use “please” and “thank you” if you ask someone to do something for you.
小題1:What is the text mainly about?

A．Good ways of studying English well.

B．Suggestions on becoming a confident speaker.

C．Things to pay attention to when speaking English.

D．How to correct your mistakes as you speak English.

小題2:How many tips does the author offer in this text?

A．9.

B．10.

C．11.

D．12.

小題3:In this passage, the underlined word “hesitant” in the sixth paragraph means “________”.

A．sure about what to do

B．fast to make a good decision

C．successful in answering questions

D．uncertain about how to express yourself

小題4:This text is most probably written for ________.

A．English beginners	B．native English speakers
C．English teachers	D．language experts
