AN ice ball shoots across the night sky, lighting up its path along the way, like a flying sun.
Ancient humans were afraid of the sight of comets(彗星). Many cultures believed that comets were messages sent by gods, and people thought these messages were warning signs for bad behavior. But today science and technology give us a better understanding of comets.
Last week, comet Ison ended its million-year-long journey as it flew straight toward the sun, melting most of the comet. It was hoped that comet Ison would survive this trip around the sun. Because once it got near Earth, it would have produced a great show of lights for us.
In ancient times, the coming of comet Ison might have scared people. However, now we can track a comet’s journey in our solar system. We can also study what they’re made of. There is even a project to launch a spacecraft onto a comet to study them further.
Although from the sky they look like great giant fireballs, comets are a collection of gas, ice, dust and small rocks. As a comet goes into our solar system, the sun’s solar winds blow some of the dust and gas away, giving the comet a tail. The average size of comets is about 10 kilometers in diameter(直徑). But amazingly, their tails can be 150 kilometers long! Comet Ison’s diameter was about 5 kilometers.
Today, people don’t fear comets as much as they did before. Western countries have even developed and old tradition. When people see a comet or meteoroid(流星) shooting across the sky, they call it a shooting star, People who get the chance to see one get to make a wish. It is a tradition that lives on today.
小題1:In ancient times, people thought comets were _____.

A．warning signs sent by gods

C．great shows of lights

D．flying suns

小題2:We can tell from the third paragraph that comet Ison ___.

A．finished its long journey to Mars

B．survived its trip around the sun

C．has reached the Earth

D．was melted by the sun

小題3:When a comet travels near the sun, some of the __ will be blown away by the solar winds.

A．gas and dust	B．ice and rocks
C．dust and rocks	D．rocks and tail

小題4:According to the last paragraph, what tradition lives on today?

What will the car be like in the future? Maybe we can sit in a car that can drive itself.
About 40 years ago, scientists from the United States started to develop self-driving cars (無人駕駛汽車). The most famous recent one was made by Google in 2009. There are cameras and radars (雷達) on the top of the car. They allow the computer in the car to draw a 3D map of the environment. Chinese scientists have also successfully developed a self-driving car. The car made a trip from Changsha to Wuhan.
Is a self-driving car safe? A recent study shows that robots make safer drivers than humans. If only 10% of cars on the street are self-driving, they will save 1,000 lives (生命) every year. If 90% of vehicles (交通工具) are self-driving, 21,700 lives will be saved a year. However, a self-driving car is expensive and each costs about $100,000. So it is impossible to be very popular in the near future.
根據短文內容，判斷下列句子正誤。正確的用“A”表示，不正確的用“B”表示。
小題1:American scientists started to develop self-driving cars in 2009.
小題2:Cameras and computers are on the top of the self-driving car by Google.
小題3:In China, scientists have successfully developed a self-driving car.
小題4:The more self-driving cars there are on the street, the fewer traffic deaths there will be.
小題5:The self-driving cars will be very popular in the near future.

A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury (埋葬) it in the garden and wait for it to flower（開花）. A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage users to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any poisonous（有毒的）chemicals. British researchers used the new material to develop a phone cover that includes a sunflower seed .When this new type of cover turns into waste, it forms nitrates (硝酸鹽). These feed the seed and help the flower grow. Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grows when the phone is thrown away. “We’ve only put sunflower seeds into the cover so far. But we are working with scientists to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.
As phone technology is developing so quickly, people are constantly（不斷）throwing their mobiles away. This means producers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can change this, according to the scientists.
根據短文內容，從題中所給的A、B、C、D四個選項中，選擇最佳答案。（10分）

C．It includes a sunflower seed.

D．It makes sure the seed only grows after the phone is thrown away.

小題3:The new type of phone can reduce the harm to the environment mainly ______.

A．because of the material of its cover

B．because of the sunflower seed

C．because it’s made of no poisonous chemicals

Tigers are terrible animals, but a cat is a cute animal. As a mother, the Chinese-American writer Amy Chua is just a tiger . Her book, Battle Hymn of the Tiger Mother (《虎媽戰歌》), tells us how she gives her two children education. She says that being strict is the only way to train a child’s talent. Her kids had to obey the following rules. To begin with, her kids weren’t allowed to watch TV or play computer games. Then, they were not allowed to “ hang out ” with other kids after school. They had to be the top students in their class. And they had to practice the piano and the violin for hours every day. Of course, she believes this has brought a lot of problems for herself and her kids. But she doesn’t mind because her kids have become great.

If you are one of those who want to know how to increase your vocabulary, there are some ways you may find useful. In fact, it is not that difficult to learn new words, but to remember them for a lifetime seems not to be so easy.
To make it easier, you can try word associations（聯想）. Try to find a connection between a new word and things or people you know. For example, if your neighbour is an unselfish person who cares about the needs of other people, think about this person every time you see the word, and very soon you'll start actively using it.
Try to use the words you learn as often as possible. Perhaps you are not sure which situations they should be used in, or whether you pronounce（發音） them correctly, but practice is the best way to understand that. It is not enough to find out the meaning of a word. You should hammer (敲打) it into your mind by using it in actual conversations in everyday life.
Also, it may be helpful to know the meaning of the word roots, prefixes (前綴) and suffixes （后綴）， especially if they have a Greek or Latin origin（起源）． Even if you meet a long unfamiliar word, it will be easy to know its meaning if you know the general meaning of its parts. For example, if you see the word "philanthropy", it won't be difficult to surmise what it means if you know that "anthropo" means "human" and "philo" means "loving". Not only can ancient Greek and Latin be helpful, but a number of modern languages as well. So, if you speak French, Italian, Spanish or Portuguese, guess the meaning of an unfamiliar English word if it sounds like a word from another language you know.
小題1: Which of the following old sayings can show the main idea of Paragraph 3?

A．Every dog has his day.

B．Practice makes perfect.

C．Every coin has two sides.

D．Where there is a will there is a way.

小題2: According to the last paragraph, what does the writer think is important?

A．Learning to use several different modern languages.

B．Learning some very difficult words in the English language.

C．Knowing the meaning of the word roots, prefixes and suffixes.

D．paying more attention to words that have a Greek or Latin origin.

小題3:The underlined word "surmise" in the last paragraph means_______.

A．guess	B．suggest
C．prove	D．remember

小題4: what's the writer's purpose in writing the passage?

A．To tell us how he or she learnt English well.

B．To explain why it is not hard to learn new words.

C．To prove that learning new words can be really fun.

D．To tell us some good ways of remembering new words.
