When something goes wrong, it can be very satisfying to say, “Well, it’s so-and-so’s mistake.” or “I know I’m late, but it’s not my fault; the car broke down.” It is probably not your mistake, but once you form the habit of blaming (指責) somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.
Winners are great at solving problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague (同事) causes you problems on the job for being short of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t depend on the person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.
This is what being a winner is all about – creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and chances to develop their own talents. So, stop focusing on “whose mistake it is.” Once you are confident about your power over bad situations, problems are just stepping stones for success.
小題1: What does the underlined word “remedy” probably mean?

A．Avoid.	B．Accept.
C．Improve.	D．Consider.

小題2: When your colleague brings about a problem, you should ______.

A．blame him for his being short of responsibility

B．find a better way to deal with the problem

C．tell him to find the cause of the problem

D．ask a more able colleague for help

小題3: What can be the best title for the passage?

A．A Winner’s Secret.	B．A Winner’s Chance.
C．A Winner’s Problem.	D．A Winner’s Progress.

Do you know why so many animals do not stay in one place? Birds, fish and other animals move from one place to another place at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration is probably the migration of fish, which is called “salmon”(鮭魚). This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it will return to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster(龍蝦). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another place, but at other times we don’t. Maybe living things just like to travel.

小題1:The reason for most of the animals to move is ________.

A．to get away from un-crowded places	B．to find their own parents
C．to want to kill themselves	D．to find food more easily

小題2:Where does young salmon(鮭魚) spend its life?

A．In fresh water.	B．In salt water.
C．In mountain homes.	D．In its birthplace.

小題3: When do the lobsters(龍蝦) begin to move another place?

A．When their homes become too crowded.

B．When the season of the bad weather arrives.

C．When they want to give birth.

D．When their food is eaten up.

小題4: The underlined word migration in the passage means ________.

A．遷徙	B．習性
C．運動	D．尋覓

The police find most criminals (罪犯) because somebody tells them who the criminals are. They find other criminals by using science and their computers. When there is a bank robbery (搶劫), the police first look through their computers for the names of the bank robbers that they know about. Then they go and talk to any of these robbers who are not in prison (監獄). They ask them where they were when the robbery happened. If any of these people cannot give a good answer, the police will often use science to find out if one of them is the robber.
Many criminals leave something of themselves at the places of the crimes like a fingerprint or a hair. Or they take something away on their shoes or clothes, like dirt or animal hair. If they leave behind some of their blood or their hair or a piece of skin, it will have their DNA inside it.
Everyone’s DNA is different and their fingerprints are also different. So, if a criminal cuts himself during a robbery or leaves his hair, or even a small piece of skin, scientists can find out what his DNA is. The police can then ask the person they think is the robber to give them his hair or some blood and see if it has the same DNA. Many criminals are in prison today because of this kind of evidences .
根據上文內容判斷正 ( T ) 誤( F )
小題1:Usually the police find criminals because they use their computer.
小題2:The police do not usually ask criminals who are in prison about a crime because these criminals could not have done it.
小題3:The most useful evidences that criminals leave at the places of their crimes are things with their DNA in them.
小題4:Many criminals usually take something away only on their shoes after the crimes.
小題5:The story is about a bank robbery.

Some of the greatest problems we face today are the destruction (破壞) of our environment. Brown clouds, polluted water，endangered wild animals…. these problems seem so huge.
So my family does what we can. We take cloth bags to stores instead of using plastic bags. We walk where we don't have to drive…
But does it do any good? When I am the only one in line at the market with cloth bags, am I doing any good? Does my walking to stores make any real difference to the world?
I recently learned something about flamingos(火烈鳥) which like to get together in groups of a thousand or more. Every year, when the time comes for migration(遷徙)，a few of them first take off from the lake. But none of the others seem to notice. So the small group returns. However, the next day they try again. This time a few more fly along with them, but most of them still pay no attention, so they return again. They try for several times. Every time a few more birds join in but, since thousands of the others still take no notice, the great migration plan is once more stopped.
Then one day something changes. The same small group of birds once again starts flying and a small number more join in just as before. then more. Finally, they all take flight and the migration really begins. What a spectacular sight it must be — thousands of flamingos taking off into the sky at once !
