阅读下列短文,从每题所给的A、B、C、D四个选项中,选出最佳选项。[来源:学&科&网]
The human body is a living machine , and , like all machines , it needs “fuel” (燃料) to supply it with energy . This is provided by the food we eat . But how much do we need to stay healthy ?
The energy value of food is usually measured in calories . A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different , as the pictures show . Also , the number of calories you use at any one moment normally depends on the activity you are in . For example , you need more calories for standing than for sitting , more for running than for walking , and so on .
The energy in food is in the form of three kinds of chemical materials-carbohydrate (碳水化合物), protein(蛋白质)and fat . Carbohydrate provides 3.8 Cal/gm , protein4.0 Cal/gm , and fat 8.8 Cal/gm . Each food contains different amount of these materials , as the round pictures show .
1.The amount of calories supplied by equal amounts of milk , rice , and peanuts is the largest in the case of .
A.milk B.rice C.peanuts D.rice or peanuts
2.Choose one statement from among A-D that agrees with the passage and the pictures above .
A.You need more calories for swimming than for mountain climbing .
B.Food contains energy in the form of carbohydres , proteins and fuel .
C.Different people need different amounts of energy depending on their age , sex and the activities they are in .
D.3 grams of milk provides 16.6 calories because carbohydrate provides 3.8 Cal/gm , protein 4.0 Cal/gm and fat 8.8 Cal/gm .
3.This article mainly tells us ________________.
A.all the energy is in food
B.the human body needs energy
C.the number of calories depends on your activity
D.we must only eat peanuts to get calories

第一节,阅读下面短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。
Bollworms are a traditional threat to cotton crops.Young ones feed on the boll,the part of the cotton plant that contains the seeds.
A bacterium known as Bt is able to kill bollworms and some other pests.Bt is the short form for Bacillus thuringiensis.It was discovered in the early twentieth century.Farmers began using Bt as a natural pesticide(杀虫剂).
Then,in the 1990s,researchers found a way to grow cotton plants that contain a Bt gene.The genetically improved cotton plant produces liquid that kills bollworms.Farmers around the world are now growing an estimated fourteen million hectares of Bt cotton.
Cotton bollworms also attack other crops.But scientists in China recently reported that Bt cotton may help prevent bollworm in other crops growing nearby.
The study involved crops grown in six provinces of northern China between 1992 and 2008.The study area contained three million hectares of cotton and twenty-two million hectares of corn,peanuts,soybeans and vegetables.
The researchers say the study suggested that Bt cotton not only controls bollworm on the transgenic cotton,but also may reduce its existence on other crops.And that reduction,they say,may decrease the need for insecticide use in general.
But the researchers also pointed out concerns.They say bollworms could develop resistance to the cotton plants designed to resist them.And they noted that insects called mirids have become “key pests” of cotton in China.They said this is because of a decrease in pesticide use made possible by Bt cotton.
The researchers say they do not believe that Bt cotton alone can solve all insect problems.Instead,they say farmers in China should consider it just one part of pest management systems.
1.What is Bt in this passage?
A.It's a kind of hi-tech invention. B.It's a natural bacterium.
C.It's a kind of pest. D.It's a man-made pesticide.
2.Bt cotton has all the advantages EXCEPT that ________.
A.it resists bollworms
B.it does good to other crops growing around
C.it reduces the use of insecticide
D.it helps to develop new insects
3.The underlined word “ones” in the first paragraph refers to ________.
A.bollworms B.cotton crops C.cotton seeds D.pests
4.From the passage,we can infer ________.
A.farmers around the world are now growing a large area of Bt cotton
B.researchers are probably now searching for new ways to solve other cotton problems C.bollworms could not exist in Bt cotton any longer
D.Chinese scientists found the way to grow Bt cotton
