How Do Animals Catch Their ZZZ’s?
Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard（蜥蝎）likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it ,it will shake the branch and knock the lizard off ,and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping.
Corillas（大猩猩）like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches ,twigs ,and leaves into a comfortable bed .Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks ,they don’t use a nest .They just lock their feet around a branch and hang on .A special tendon（腱）in their legs in automatically tight when they are at rest ,so they won’t let go and fall.
Dolphins live underwater ,but must come to the surface to breather .Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this ,lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open.

D
We all know what it is like to be unable to turn your head because of a cold in the muscles of your neck, or because an unexpected twist has made your neck ache and stiff. Your whole body feels tight. The slightest move makes you jump with pain. Nothing could be worse than a pain in the neck.
That is why we use phrase to describe some people who give you the same feeling. We have all met such people.
One is the man who always seems to be clapping his hands—often at the wrong time—during a performance in the theater. He keeps you from hearing the actors.
Even worse are those who can never arrive before the curtain goes up and play begins. They come hurrying down to your row of seats. You are comfortably settled down, with your hat and heavy coat in your lap. You must stand up to ;et them pass. You are proud of your self—control after they have settled into their seats…Well, what now…Good God, one of them is up again. He forgot to go to the men’s room, and once more you have to stand up, hanging on to your hat and coat to let him pass. Now, that is “a pain in the neck.”
Another, well—known to us all, is the person sitting behind you in the movies. His mouth is full of popcorn; he is chewing loudly, or talking between bites to friends next to him. None of them remain still. Up and down, back and forth, they go—for another bag of popcorn, or something to drink.
Then, there is the main sitting next to you at a lunch counter smoking a smelly cigar. He wants you to enjoy it too, and blows smoke across you food into your mouth.
We must not forget the man who comes into a bus or subway car and sits down next to you, just as close as you will let him. You are reading the newspaper and he leans over and stretches his rock so that he can read the paper with you. He may even turn the paper to the next page before you are ready for it.
We also call such a person a “rubber neck,” always stretching his neck to where it does not belong, like neighbors who watch all your visitors. They enjoy invading your privacy. People have a strong dislike for rubbernecks. They hate being spied upon.

C．Kids’ comic books.                              D．Science text books.
69．How do you feel when late comers walk back and forth in front of you in a cinema?
A．Ignored.              B．Bored.                C．Disturbed            D．Relaxed.
70．A “rubber neck” often                  .
A．says bad words behind people.
B．quarrels face to face with neighbors.
C．bargains the price with sales women

B

People tend to become more personal and hide less of themselves when using email. Researchers from Open University in Britain have found in a recent study that there are good reasons for this.
The team of researchers asked 83 pairs of students, all strangers to each other, to solve a problem. They had to discuss this question: If only five people in the world could be saved from a world disaster, who should they be? The pairs of students had to talk over the problem either face to face or by computers. Dr. Johnson said, “They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face. When the computers were fitted with cameras so that students could see each other, this limited the personal side of the conversation.”
Generally the information was not extremely personal. It was mainly about things such as where they went to school, or where they used to live. But some students discussed their love stories, and personal childhood experiences.
Dr Johnson believes that emailing encourages people to focus on themselves. And when they do this, they become more open, especially if there are no cameras. “If you cannot see the other person, it becomes easier to talk about yourself. This is because you are not thinking what the other person is thinking of you. So emailing has become the modern way of talking,” said Dr. Johnson. However, this style of talking is not entirely new. “In the 19th century people started to use the ‘telegraph’ to communicate. Now the same kind of thing has happened and people ended up speaking more freely.”
Dr. Johnson thinks that emailers need to know about these effects of emailing, especially when they start work in a company. “ If you don’t know about it, you could find yourself saying more about yourself than you wanted to.”
60. The subject discussed in this passage is _______.
A. how people open up when emailing               B. how people do research studies
C. how to communicate at work                         D. how to discuss and solve a problem

A. they didn’t talk about very personal things     　　B. they couldn’t see each other
C. the cameras on the computers were turned on 　　D. they had to discuss a question
62. What does the underlined sentence refer to?
A. The telegraph.          B. The computer.          C. Emailing.          D. Face-to-face talk.

A. focus on oneself when emailing                            B. talk more freely in emails than usual

Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , he number of such reasons is small . Pruning involves the cutting away of overgrown and unwanted branches , and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way .
First , pruning may be done to make sure that trees have desired shape or size . The object may be to get a tree of the right height , and at the same time to help the growth of small side branches , which will thicken its appearance or give it a special shape . Secondly , pruning may be done to make the tree healthier . You may cut out diseased or dead wood , or branches that are rubbing against each other and thus cause wounds . The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air .
One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal (愈合) . Often there is a race between the healing and the disease as to whether the tree will live or die , so that there is a period when the tree is at risk . It should be the aim of every gardener to reduce that risk of death as far as possible . It is important to make the area , which has been pruned , smooth and clan , for healing will be slowed down by roughness . You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose . Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference (妨碍) from the leaves and also it is very unlikely that the cuts you make will bleed . If this does happen , it is , of course , impossible to paint them properly .
71．Why should running be done ?
A．To make the tree grow taller .               B．To improve the shape of the tree .
C．to get rid of the small ranches .             D．To make the small branches thicker .
72．Trees become unhealthy if the gardener         .
A．To help a wound to dry .
B．To cover a rough surface .
C．damages some of the small side branches
D．Allows too many branches to grow in the middle
73．Why is a special material painted on the tree ?
A．To help a wound to dry .                      B．to cover a rough surface .
C．To make a wound smooth .                   D．To prevent disease entering a wound .
74．A good gardener prunes a tree         .
A．several times throughout the year         B．as quickly as possible
C．occasionally when necessary                 D．regularly every winter
75．What was the author’s purpose when writing this passage ?
A．To discuss different methods of pruning .
B．To introduce some common knowledge of pruning .
C．To explain how trees develop disease .
D．To give practical instruction for pruning a tree .

An Experiment
Materials: Newspaper, ‘ACE’ hardware ruler (1/8 “think”), a flat table.
Purposes: We’ll show that there is air pressure pushing on us, from every direction while we’re on this Earth.

Procedure:First put a thin ruler on a flat table with a little
less than half of it hanging off the edge of the table
(see the drawing below). Next place a sheet of newspaper
over the ruler flat against the table. Make sure to have
as little air as possible under the paper so that the fold line of the newspaper is at the ruler. Then quickly strike the end of the ruler hanging off the edge of the table. If you strike it quick enough, the ruler will break near the table edge.
What’s going on?
The Earth is covered in a layer of air that is nearly 80 miles thick and at sea level (the bottom) exerts or ‘pushes’ hard almost 15 pounds of pressure per square inch. That means that a full sheet of newspaper laid out flat has nearly 9,300 pounds of air above it.
When you break the ruler above, you are able to break it because of the "heavy" air pushing down on the paper while you quickly strike the ruler. At first the table is pushing back on the paper, and if you move the ruler quick enough, other air around the edges of the paper can"t get under the paper fast enough, so you are trying to lift that 9,300 pounds with the ruler! Some air gets under the paper, but not enough, so the ruler breaks.
1．By doing the experiment, we may realize         .
A．that air exits everywhere
B．why there are directions
C．that we live with air pressure
D．how air helps on the earth
2．How many steps are there in this experiment?          .
A．2      B．3       C．4       D．5
3．The underlined word “exert” probably means       .
A．cover completely            B．advocate actively
C．influence gradually D．press heavily
4．The ruler breaks under a quick strike mainly because of          .
A．the air pressure on the newspaper   B．the heavy weight of the newspaper
C．the heavy weight of the flat table    D．the strong power used on the ruler
