15.Many people catch a cold in the springtime or fall.It makes us wonder.If scientists can send a man to the moon,why can't they find a way to deal with the common cold?The answer is easy.There are actually hundreds of kinds of cold viruses out there.You never know which one you will get,so there isn't a cure for each one.
When a virus attacks your body,your body works hard to get rid of it.Blood rushes to your nose and brings congestion(擁塞)in it.That is to say,you cannot breathe well.As a result,you feel terrible.However,your body is actually"eating"the virus.Your temperature rises and you get a fever,but the heat of your body is also killing the virus.Besides,you have a runny nose to stop the virus from getting into you.You may feel terrible,but in fact your wonderful body is doing everything it can to kill the cold.
Different people have different ways to deal with common colds.In the United States and some other countries,for example,people might eat chicken soup to feel better.Some people take hot baths; some drink warm water,milk,or things like that; other people take medicine to stop the fever,congestion,and runny nose.
Some scientists suggest you should not take medicine when having a common cold,saying that it is bad for you to do that.If you take medicine,your body will stop reacting to the virus and thus won't have a way to fight it and kill it,which makes the virus stay in you longer.Bodies can do an amazing job on their own.

66.According to the passage,what makes us wonder?C
A.Why we never know which cold we will get.
B.Why scientists are able to send a man to the moon.
C.Why scientists cannot find a cure for the common cold.
D.Why there are hundreds of kinds of cold viruses out there.
67.Which of the following is NOT mentioned in the passage when we are suffering from colds?B
A.Fever.             B.Headache.
C.Runny nose.        D.Congestion.
68.When you have congestion in your nose,A.
A.you will not be able to breathe well
B.your temperature is going to rise
C.your blood is running too fast
D.you will have a runny nose
69.According to the passage,people may deal with common colds in different ways EXCEPTD.
A.taking medicine        B.taking hot baths
C.eating chicken soup    D.drinking alcohol
70.Some scientists advise you not to take medicine when you have a common cold becauseA.
A.your body will fight and kill the virus on its own
B.your body will probably react too much to the virus
C.it will take longer time for your body to get over the virus
D.it will not be able to stop the fever,congestion or runny nose.

4.The African elephant,the largest land animal remaining on earth,is of great importance to African ecosystem(生態(tài)系統(tǒng)).Unlike other animals,the African elephant is to a great extent the builder of its environment.As a big plant-eater,it largely shapes the forest-and-savanna(大草原)surroundings in which it lives,therefore setting the termsof existence for millions of other animals that live in its habitat.
It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbushes,and pulls branches off big trees.This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas.In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants make open spaces,allowing new plants to grow on the forest floor.In such situations,the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species.If the elephant disappears,scientists say,many other animals will also disappear from vast areas of forest and savanna,greatly changing and worsening the whole ecosystem.

29.What is the passage mainly about?B
A.Disappearance of African elephants.
B.The effect of African elephants'search for food.
C.Forests and savannas as habitats for African elephants.
D.The eating habit of African elephants.
30.What does the underlined phrase"setting the terms"most probably mean?C
A.Worsening the state.
B.Improving the quality.
C.Deciding the conditions.
D.Fixing the time.
31.What do we know about the open spaces in the passage?A
A.They are attractive to plant-eating animals of different kinds.
B.They result from the destruction of rain forests.
C.They provide food mainly for African elephants.
D.They are home to many endangered animals.
