Passage One

Animals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home.

Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as hibernation.

There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating.

One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice.

Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators.

Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Others do not.

36. Hibernation is a seasonal practice. This means it ______.

A. takes place only during a particular season

B. occurs only during the night

C. is a daily practice

D. only happens when a species becomes over-populated

第4题：

It should go without saying that the focus of UML is modeling.However,what that means,exactly,can be an open-ended question.（ ）is a means to capture ideas,relationships,decisions,and requirements in a well-defined notation that can be applied to many different domains.Modeling not only means different things to different people,but also it can use different pieces of UML depending on what you are trying to convey.In general,a UML model is made up of one or more（ ）.A diagram graphically represents things,and the relationships between these things.These（ ）can be representations of real-world objects,pure software constructs,or a description of the behavior of some other objects.It is common for an individual thing to show up on multiple diagrams;each diagram represents a particular interest,or view,of the thing being modeled.UML 2.0 divides diagrams into two categories:structural diagrams and behavioral diagrams.（ ）are used to capture the physical organization of the things in your system,i.e.,how one object relates to another.（请作答此空）focus on the behavior of elements in a system.For example,you can use behavioral diagrams to capture requirements,operations,and internal state changes for elements.

A.Activity diagrams
B.Use-case diagrams
C.Structural diagrams
D.Behavioral diagrams

答案：D
解析：
UML的核心关注内容是建模。然而建模是一个开放性的问题。建模是采用合适并预先定义的符号来描述捕获的思想、关系、决策和需求，并且建模可应用到多个领域。建模对不同的人有不同的含义，可以使用UML中不同的部分来描述你所要涵盖的内容。一般来说，UML模型是由一个或者多个diagram组成。一个diagram使用图形化的方式描述了事物以及事物之间的关系，而事物代表了真实世界中的对象、软件构件或对象行为。常常一个独立的事物会在多个diagram中展现，每个diagram建模了该事物的不同方面。UML 2.0将diagram分为两大类：结构化diagram和行为diagram。结构化diagram主要用于捕获系统的物理组织结构，如一个对象与其他对象的关系。行为diagram则用于捕获需求、操作以及元素内部状态的变化。

This is not because they want a ride, but because they find easy food in the parasites (寄生虫 ) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.

Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals ( 珊瑚 ) of the sea. In their skins they have tiny plants act as "dustman", taking some of the waste products form. the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are ever prevented from lighting so that they cannot live normally, the corals will die.

第9题：

The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.
Which of the following statements is NOT ture?

a.Drugs are always given to animals for medical reasons
b.Some of the additives in our food are added to the food itself and some are given to the living animals
c.Researchers have known about the potential dangers of food additives for over thirty-five years.
d.Food may cause forty percent of cancer in world.

答案：A

第10题：

Can animals be made to work for us?Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings.
They point out that at a circus,for example,we may see elephants,monkeys,dogs and other animals doing quite skillful things．Perhaps you have seen them on the television or in a film．If you watch closely,you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward．The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them.
Of course,as we know,dogs can be used to guard a house,and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near．But it may be possible to train animals to work in factories．In Russia,for example,pigeons which are birds with good eyesight,are being used to watch out for faults in small steel balls that are being made in one factory．When the pigeon sees a ball which looks different from others,it touches a steel plate with its beak．This turns on a light to warn people in the factory．At the same time a few seeds are given as a reward．It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour.
Apes have been used in America in helping to make cars,and scientists believe that these large monkeys may be one day gather crops and even drive trains.

What made scientists think animal can be made to work for us one day?

A.Animals are very skillful at a circu
B.They are big and stron
C.Some animals are as clever as human being
D.Animals can be trained because they like to get something as a rewar

答案：A
解析：
参见句子：They point out that at a circus，for example，we may see elephants，monkeys，dogs and other animals doing quite skillful things．句中they指的就是scientists。
