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 placesB．to find their own parents
C．to want to kill themselvesD．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(xí)性
C．運動D．尋覓

小題1:D
小題2:B
小題3:B
小題4:A

試題分析：鳥兒、魚和其他的動物為什么會從一個地方遷居到另一個地方呢？大多數(shù)遷居是想更容易地找到食物。其他的是要離開太擁擠的地方。比如鳥在冬天來臨之前，遷徙到溫暖的地方；有些魚溫水去，卻要到冷水里覓食。再如鮭魚和龍蝦的遷徙也很有意思。
小題1:細(xì)節(jié)理解題。根據(jù)most of them move to find food more easily,可知，大多數(shù)遷居是想更容易地找到食物。故選D。
小題2:細(xì)節(jié)理解題。根據(jù)This fish is born in fresh water but it travels many miles to salt water. There it spends its life.可知，鮭魚生活在咸水了。故選B。
小題3:推理判斷題。根據(jù)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.可知，每年當(dāng)壞天氣的季節(jié)到來時，龍蝦們就排著隊開始橫穿海底。故選B。
小題4:詞義推測題。根據(jù)前后句子的意思可知，最著名的遷徙可能是一種叫鮭魚的魚。它們生在淡水了，卻要跋涉許多英里到咸水了生活。老了在回到出生的淡水區(qū)生兒育女，然后死去。migration的意思是move，遷居、遷徙。故選A。

Character, courage and confidence are words you might use to describe your heroes. These words can describe you! Take action as follows and you’ll be a hero, too!
Part 1: Character
Character is something that makes you the person you are like being honest, friendly, and helpful. See the chart below. On the left is our standard of good character. Write down your promise for each line on the right. Then, get a witness（證人）to sign it. Put it up where you’ll see it every day and do your best to keep it.
To build your character
Your promise
I will do my best to…
 
be honest and fair.
eg. I’ll tell the truth when mom asks if I have finished my homework.
be friendly and helpful.
eg. I’ll help my friend with lessons.
be polite and kind.
eg. I’ll show good manners in class.
be courageous and strong.
eg. I’ll take part in the English singing contest.
Part 2: Courage
Of course it’s going to take a lot of courage t keep your promise. Courage is challenging yourself to do something even though you think it might be hard. For each promise, find out two or three ways to help you keep it. For example, if you think that Being Honest is the hardest promise for you to keep, one of the ways might be “Tell people about my promise so that I won’t break it”.
Part 3: Confidence
Confidence is believing that you have the skills to do something. Do you have a beautiful singing voice? Are you a good painter? There are all talents that can make you feel good, as well as the people around you. Once you’ve decided what your special skill is, think about how you can use your skill to make your corner of the world a better place. If you’re good at art, try painting a picture on an old wall in your school (of course, make sure you’re allowed).
小題1:According to the writer, a hero should be           .
A. beautiful                  B. confident              C. good-looking

The trees have been on the earth for millions of years.  小題1: Disease(疾病) is destroying trees. For example, in the 1970s, many trees in Europe were killed by disease.
小題2: This new danger attacks all the forests and woods of Europe from northern Sweden to southern Italy. First the branches turn yellow and brown. Then the trees’ leaves fall. The roots and the trunk shrink(萎縮). Finally the trees die. In the Black Forest in southern Germany, 75％of the trees have been destroyed or killed．
小題3: Nobody knows exactly, but it is probably air pollution or acid rain(酸雨). Factories, power stations and cars give off tons of smoke with acid into the air. Sunlight turns these into something harmful which fall with rain or snow onto the trees.
What can be done about acid rain? 小題4:
Acid rain doesn’t always fall on the countries which produce the pollution. The wind carries it from one country to another. Badly, the governments don’ t want to spend money on it if it won’ t harm the trees in their own countries.
小題5: The rainforests of Asia and South America are being cut down for firewood and building materials. Something must be done. If the trees die, we will, too.
根據(jù)材料內(nèi)容，從下面五個選項中選出能填入文中空缺處的最佳選項，使短文意思通順，內(nèi)容完整。
A．What is killing the trees?
B．But today trees are in great danger.
C．Trees are also killed by people.
D．Now an even greater danger is destroying trees.
E. Why don’t the governments do something to save the trees?

Some people have a kind of magic. They will make you comfortable while they are around. You feel at ease while talking to them. How is it done? Here are several skills that good talkers have. If you follow the skills, they'll help people feel relaxed and make friends with them quickly.
First of all, good talkers ask questions. Almost anyone, no matter how shy he is, will answer a question. One well-known businesswoman says, "At business lunches, I always ask people what they did that morning. It's a common question, but it will get things going." From there you can move on to other matters—sometimes to really personal questions. And how he answers will let you know how far you can go.
Second, once good talkers have asked questions, they listen to the answers. This point seems clear, but it isn't. Your questions should have a point and help to tell what kind of person you are talking to. And to find out, you really have to listen carefully and attentively. Real listening at least means some things. First it means not to change the topic of conversation. If someone insists on one topic, it means he's really interested in it. Real listening also means not just listening to words, but to the voice. If the voice sounds bored, then, it's time for you to change the topic.
Finally, good talkers know well how to deal with the moment of saying good-bye. If you're saying it, you may give him a handshake and say, "I've really enjoyed meeting you." If you want to see that person again, don't keep it a secret. Let people know your thoughts.
小題1:Asking questions might be a quite good and suitable way ________.
A．for you to make more and more new friends
B．to begin your business talks
C．to get things going
D．for you to make a deep and lasting impression on others
小題2:After asking somebody a question, it'll be polite of you to ________.
A．a(chǎn)gree with what others say all the time
B．listen to his reply attentively
C．wait impatiently for his answer
D．go on asking him more questions
小題3:Generally speaking, good talkers are persons who ________.
A．a(chǎn)re not good at making any topic interesting
B．never talk too much or too little
C．a(chǎn)lways speak in a gentle way
D．know when they should change the topic of the talk
小題4:If you really want to meet someone again, ________.
A．you may take him as your lifelong true friend
B．it seems necessary for you to let him know it
C．it's proper for you to give him a second handshake
D．it'll be helpful for you to have further understanding of him
