】七选五填空。

We all face quantities of stresses in day-to-day living, whether at work, in the home, or anywhere in between. 1. Here's how stress can help us on an everyday basis.

◆ Sharpen your memory.

Did you ever notice that sometimes when you are stressed, your memory seems to improve? Remember that test you passed where the answers seemed to come out of nowhere? 2. It's because of stress hormones（荷尔蒙）that increase your alertness(机敏) when it's most needed.

◆ 3.

Successful employees turn stress into motivation. Have you ever noticed that you get the least amount of work done when you have the fewest deadlines? Too little stress can affect how much you actually get done. When you take risks and choose to get over the difficulty, it improves your mental toughness and self-confidence.

◆ Helping you resist the attack of illness.

4. 　 Believe it or not, the right kind of stress can help your body's defenses against illness. When you get sick, stress causes you to make hormones that battle threats to your health. That burst of stress is helpful to your immune system when your body faces a　 threat.

◆ Making your life more interesting.

Think about some stressful situations that we consciously put ourselves in to make life more interesting and enjoyable, like asking someone out on a first date, conquering a known fear, or learning something new. These may not immediately come to mind when you think of stress because of the positive outcomes. 5.

A．Helping you get an advantage at work.

B．Helping you get through difficult times.

C．This will happen whenever you are stressed.

D．That's one way your brain responds to stress.

E. You need a healthy immune system to help fight off diseases.

F. But they're the types that can help you achieve fulfillment and happiness.

G. But handled properly, stress can have many benefits for the body and mind.

If you’ve spent any amount of time boating, fishing, or bird-watching at lakes and rivers, you have most likely seen fishes jumping out of the water. I have seen it many times. Certainly, fishes will exit water in desperate attempts to escape enemies. Dolphins take advantage of the behavior, forming a circle and catching the frightened fishes in midair. But just as we may run fast from fun or from fear, different emotions might motivate fishes to jump.

Mobula rays（蝸鲼）aren’t motivated by fear when they throw their impressive bodies—up to a seventeen-foot wingspan (the distance from the end of one wing to the end of the other) and a ton in weight—skyward in leap（跳跃）of up to ten feet. They do it in schools（鱼群）of hundreds. They usually land on their bellies, but sometimes they land on their backs. Some scientists think it might be a way of removing parasites（寄生虫）. But I think that the rays are enjoying themselves.

In the clear waters of Florida’s Chassahowitzka National Wildlife Refuge, I watched several schools of fifty or more mullets（鲻鱼）moving in beautiful formation. Their well-built bodies were most evident when they leaped from the water. Most of the time I saw one or two leaps by a fish, but one made a series of seven. They usually land on their sides. Each jump was about a foot clear of the water and two to three feet in length.

Nobody knows for sure why the fish leaps. One idea is that they do it to take in oxygen. The idea is supported by the fact that mullets leap more when the water is lower in oxygen, but is challenged by the likelihood that jumping costs more energy than is gained by breathing air. It is hard to imagine they will feel any fresher when back in water.

Might these fishes also be leaping for fun? There is some new evidence. Gordon M. Burghardt recently published accounts of a dozen types of fishes leaping repeatedly, sometimes over floating objects—sticks, plants, sunning turtle—for no clear reason other than entertainment.

1.What can we say about the dolphins in Paragraph 1?

A.They have great escaping skills. B.They are easily frightened.

C.They are very clever. D.They love jumping.

2.What do the ray and the mullet have in common when jumping?

A.Both do it in groups. B.Both land on their bellies.

C.Both jump many feet out of water. D.Both make leaps one after the other.

3.How does the author feel about the idea mentioned in Paragraph 4?

A.It is valuable. B.It is interesting.

C.It is imaginative. D.It is questionable.

4.Which may be the reason for fish leaps according to the author?

A.To remove parasites. B.To amuse themselves.

C.To take in more oxygen. D.To express positive emotions.

There is one word that is on the lips of Americans , day and night , “Sorry”.

One time as I was walking on the street , a young man ran by hurriedly , brushing against my handbag . Even as he continued on his way , he turned back and said “sorry” to me . Even in a rush , he didn’t forget to apologize .

One day , after I bought some apples , the salesman was giving me the change , but I wasn’t ready for it , and a coin dropped on the ground, “I’m sorry ,” he said while bending down to pick it up . I was puzzled —why would he apologize when it was my fault ?

Another time , I stepped on a man’s foot in an escalator . At the same time , we both said “sorry” . I thought it interesting : was it really necessary for him apologize ?

Later on , an American friend explained to me that according to the American ideas, the escalator is public place which everyone should be able to stand in . After someone occupies a position in the escalator , making it difficult for someone else to find a place to stand in , isn’t it necessary to express an apology ?

During my stay in America , I gradually realized that when friction (摩擦) occurs in daily life , Americans don’t care much about who is responsible . If someone is troubled , a “sorry” is always necessary . Even if the other person is hurt , the “sorry” would cool tempers . Perhaps this is why I never saw anyone quarreling on the buses , subways or streets in America .

1.When I was walking in the street , ____ .

2.When the salesman gave me the change , _____

3.The man on whose feet I stepped apologized to me because ____ .

4.In this passage , the author seems to feel _____ the Americans’ “sorry”.
