1.All our food comes from the soil(土壤).Some of us eat meat,but animals live on plants.If there were no plants,we should have no animals and meat.So the soil is necessary for life.
The top of ground is usually covered with grass or other plants.Plants grow in soil,which has a dark color.This dark soil is humus,dead leaves,dead plants and animals waste make it,but this takes a long time  When the humus has been made,plants can grow well in it.All soil needs food.If we don't give it any,the plants will be weak.Animals waste is the best food for the soil,but chemical fertilizers(化肥) are also very useful.The same crop should not be grown in the same place every year,it is better to have a different crop.A change of crop and the use of a good fertilizer will keep the land in good condition
When the soil is dry,the wind blows it away.Sometimes heavy rain carries the humus down to a river.People should grow more and more trees and grass to stop wind from carrying the humus away.It takes hundreds of years to make humus,and so we must save every bit of it.Without soil,where can we grow food?

 62.From the text,we know people live onA
A.soil         B plant       C.meat      D.a(chǎn)nimal
63.The underline word"humus"meansB in Chinese.
A土壤       B腐殖土       C微生物      D.粘土
 64.We shouldC to keep the soil.
A  kill more animals       B make more humus
C.grow more trees and grass       D.give more fertilizers
 65.The best title of this text should beB.
A  Humus is hard to make         
B Soil is necessary to people
C  The same crop can't be grown in the same place every year
D  Soil's food is chemical fertilizers.

分析 我們的食物來源于土壤,土壤對我們很重要,短文介紹了土壤及土壤與農(nóng)作物的關(guān)系.

解答 62.A 推理判斷題 根據(jù)"All our food comes from the soil(土壤).Some of us eat meat,but animals live on plants.If there were no plants,we should have no animals and meat"可知,人們的食物來源于土壤,故答案為A
63.B 推理判斷題 根據(jù)"dead leaves,dead plants and animals waste make it"可知,humus是由枯死的樹葉、動植物形成的,故"humus"意為"腐殖土",答案為B
64.C 細節(jié)理解題 根據(jù)"People should grow more and more trees and grass to stop wind from carrying the humus away"可知,我們應(yīng)該種樹、種草來保護土壤,故答案為C
65.B 推理判斷題 短文主要介紹了我們的食物來源于土壤,土壤對我們很重要,故答案為B Soil is necessary to people

13.閱讀短文,從各題所給的四個選項中,選出最佳答案.
Cars are lots of fun,but they could also be dangerous.We have to be careful when we drive them or ride in them.
It's always a good idea to put on your seat belt when you're in a car.Why?Think about this example:You put an egg on a skateboard and give it a push.If the skateboard hits a stone,it will stop,but the egg won't.It will fly through the air,hit the ground and break.
Now,think what would happen if you tied the egg to the skateboard.When the skateboard hits a stone,the egg won't go flying; it will stay safely on the skateboard.
Volvo,a famous Swedish carmaker,was the first to use seat belts in 1849.
Air bags are also very important for car safety,because sometimes a seat belt isn't enough.If the car is going really fast and runs into something,seat belts could even hurt the people who wear them.Most new cars have air bags in front of and next to the seats.When a car hits something,its air bags will come out quickly in less than one second to keep the people inside safe.

10.It is good to keep animals in zoos.Zoos are places for people to see many different kinds of animals from all over the world.Without zoos,most people would never see a real tiger or bear.Secondly,zoos look after the animals very well.The animals are always given food and cleaned on time.In the wild,it is not always possible for an animal to find food,so sometimes it goes hungry.Thirdly,zoos protect the animals.They offer them safe places to live in.In the wild,some kinds of animals are in danger of becoming extinct.But zoos give these animals a chance to live.Without zoos,there would be fewer kinds of animals in the world.
However,some people think it is unnatural and unfair to keep wild animals in cages.Most animals are kept in cages that are too small for them.The animals such as bears and tigers always look sad in cages.Wild animals should look for their own food.Anyone would not feel happy if he isn't allowed to go outside his home and animals don't like it,either.

根據(jù)短文內(nèi)容,判斷以下句子的正誤.把你認為正確的句子在答題卡相應(yīng)位置上填涂"T",錯誤的填涂"F".(共5小題,每小題1分,滿分5分)
51.If you don't go to a zoo,you can't see dogs.F
52.In the zoos,all animals are dangerous.F
53.In the wild,animals have to look for their own food.T
54.According to the last sentence,we can say animals like to stay in the cages.F
55.The writer is not sure whether it is better for animals to stay in zoos.T.
