高三英语单项填空简单题查看答案及解析

Each of us can live strong，healthy，energetic lives for a long time to come．The key？Actually，there are many of them．

Eat fewer calories，but more food

Slimming down can help prevent disease，and cutting way back on the amount you eat may even slow the aging process．When nutrition researchers invited themselves over for dinner in kitchens across the globe-from Greece to Japan to the state of Pennsylvania--they discovered a stomach-satisfying secret to good health：Pile your plate high with vegetables and fruits，add respectable parts of beans and whole grains，and ignore high-calorie food like cheeseburgers，cream sauces，and fatty meats．

Use exercise as an anti-aging vaccine

Exercise can help you gain a better quality of life as you age．It's no secret that physical activity strengthens muscles，burn calories，and puts a happy bounce in your step．But recently，researchers discovered a new，extra benefit：Exercise acts as a powerful way against the aging process itself. When exercise physiologists put healthy people aged 60 to 85 on Weight-training programs for six months then tested them for signs of free-radical(自由基) damage，they were surprised by the results．By the end of the study，low-intensity exercisers had a drop in free-radical damage，while high-intensity exercisers had a slight increase．

Find something interesting to do

Life is always busy no matter what your age．But the truth is，when people are retired，time usually does become more available for adults after 60．With this time come choices．The easy one is merely to relax：watch more TV，eat out more often，talk on the phone as much as you want．The better choice? Discover something more meaningful to devote yourself to and do it wholeheartedly．

Companion planting is the idea that some kinds of plants can help each other grow. Plants that are compatible together generally have similar needs in terms of nutrients, soil and moisture levels.

Advice about which plants are compatible is sometimes based more on tradition than proof. But experts say there is evidence to support certain combinations. These can improve harvests, reduce disease and help with pest control by attracting helpful insects.

For example, some kinds of soil bacteria take nitrogen from the air and make it into a form that plants can use. The plants hold the nitrogen in their roots. Legumes（豆科植物）are especially good at this nitrogen（氮）-fixing. Then any crops that share the same space with the legumes can get the nitrogen when the roots are broken down.

Beans and potatoes can also share territory well because their roots reach different levels in the soil. Deep-rooted vegetables get nutrients and moisture from lower down in the soil, so they do not complete with plants with shallower roots.

But some plants placed together may harm each other’s development. For example, tomatoes do not like wet soil but watercress does, so you would probably want to keep them separated.

Some kinds of produce should be kept apart even after being harvested. This is because of ethylene gas（乙烯气体）. Ethylene is a plant hormone（激素）that can cause some foods to ripen too quickly. Apples release ethylene gas. Apricots, melons and tomatoes also release a lot of ethylene. Some vegetable are easily affected by ethylene, including asparagus, broccoli, cabbage and cucumbers.

This risk of ripening too soon is why markets often separate high ethylene-producing foods from those that are sensitive to the gas. But if you put an apple in a bag with a green banana, the ethylene from the apple will make the banana ready to eat sooner.

What about peaches, plums and nectarines? These kinds of fruit do not need any help from an apple—they release enough ethylene to ripen themselves. But that does not mean there is no way to get the job done faster.

Growers suggest placing the fruit in a fruit bowl or in a paper bag with the top folded over. Keep the fruit at room temperature, out of direct sunlight. Once the fruit is soft enough, either use it or put it in the refrigerator to keep it from getting too ripe.

1.Companion planting refers to the idea that ________

A. some crops can grow together to benefit each other.

B. some crops have the similar needs of nutrients, soil and water level.

C. some plants can damage each other if grown together.

D. a good farming method to prevent natural disasters.

2.According to the text, ________cannot grow together.

A. beans and potatoes　　 B. tomatoes and watercress

C. legumes and corns　　 D. rice and sugarcane

3.What is the function of ethylene?

A. To improve the quality of fruits.　　 B. To produce a poisonous gas.

C. To keep vegetables fresh.　　 D. To make fruits ripe earlier.

4.The text is most likely to be taken from ________.

A. a newspaper of medicine　　 B. a magazine of biology
