B

Tears are nature's way making us feel comfortable. When our eyes are made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted and “red-eyes” from overwork and late hours, tears from in our eyes to clean and refresh them.

Tears are also a sign of strong emotion. We cry when we are sad and we cry when we are happy.

And tears seem to be uniqueness(唯一)of human. We know that animals also experience emotion—fear, pleasure, loneliness—but they do not shed(流)tears. From this we can conclude that tears are closely related to the emotional and biological makeup of the human species.

Biologically speaking, tears are actually drops of saline fluid, which is a little bit salty, produced by a gland(腺)in the body. Because salt is an important component, tears may actually constitute the most conclusive evidence that the human animals are the end product of a long evolutionary(進(jìn)化的)process that began in the sea.

And it is clear that, in addition to(除了)the emotional benefits, the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals which build up in response to stress and cerate a chemical imbalance in the body. Crying actually makes us feel better by correcting that imbalance and making us feel good again. And thus the emotional and the biological functions of tears merge(合并)into one and make us even more “human” than we would otherwise be.

【1】According to the passage, human beingsmay have originated in________.

A．the sea

B．the salt

C．chemicals

D．a(chǎn)nimals

【2】Which of the following is NOT a function of tears?

A．Biological.

B．Emotional.

C．Political.

D．Chemical.

【3】According to the article, which of the following is unique to humans?

A．The feeling of loneliness.

B．The state of feeling good.

C．The ability to shed tears.

D．The feeling of fear.

【4】The word “eliminate” probably means________.

A．a(chǎn)dd

B．produce

C．replace

D．remove

【答案】見解析

【解析】【1】細(xì)節(jié)題。文章第四段最后：眼淚是咸的可能是人類從大海里進(jìn)化而來的有力證據(jù)。

【2】文章中沒有涉及眼淚與政治有什么關(guān)系。

【3】文章第三段首句。

【4】該句含義為：通過眼淚，我們可以消除身體中由于緊張而產(chǎn)生的一種化學(xué)物質(zhì)。

【題目】As societies develop, their members start to see things not so much according to what they need, but according to what they want. When people have enough money, these wants become demands.

Now, it's important for the managers in a company to understand what their customers want if they are going to develop effective marketing strategies(策略). There are various ways of doing this. One way at supermarkets(超市), for example, is to interview(采訪)customers while they're doing their shopping. They can be asked what they prefer to buy and then the results of the research can be studied. This provides information on which to base future marketing strategies. It's also quite normal for top managers from department stores to spend a day or two each month visiting stores and mixing freely with the public, as if they were ordinary customers, to get an idea of how customers act.

Another way to get information from customers is to give them something. For example, some fast food restaurants give away tickets in magazines or on the street that permit customers to get part of their meal for nothing. As well as being a good way of attracting customers into the restaurants to spend their money, it also allows the managers to get a feel for where to attract customers and which age-groups to attract.

Another strategy used at some well-known parks such as Disneyland is for top managers to spend at least one day in their work, touring the park dressed as Mickey Mouse or something like that. This provides them with a perfect chance to examine the scene and watch the customers without being noticed.

【1】 The text is designed for________.

A．managers

B．salesmen

C．researchers

D．customers

【2】 Which of the following can help managers get useful information?

A．Visiting customers themselves.

B．Giving customers free food on the street.

C．Visiting parks as ordinary customers.

D．Asking customers questions at supermarkets.

【3】 What does the word “this” underlined in the last sentence refer to?

A．Visiting Disneyland.

B．Wearing attractive clothes.

C．Acting Mickey Mouse.

D．Dressing up and walking around.

【4】 The main idea of the text is________.

A．how to do market research

B．how to develop marketing strategies

C．how to find out customers' social needs

D．how to encourage customers to spend more money

How to Be a Good Tourist

We travel for work but also for fun and learning. New restaurants, galleries, temples and new architecture…These places are homes for people like us who live and work there. How would you want visitors to behave in your own home? Think about it. 【1】 There are many ways of doing this without sacrificing our own holiday.

Do your homework. 【2】 Guides will help you when you get to site, but is that the best place to go? Is it popular only because the one-day tourist can see it easily or because it is really a worthwhile place to visit? You’d better check it out.

【3】 Don’t go to your hotels for meals. Walk around, even if in the streets closest to your hotel. Eat in local restaurants. Talk to the locals. Learn a few in the local language and use them. You will surely get a smile from the hotel staff and street sellers .

Help preserve the sites. Most of the sites you visit may be visited by millions of people a year, so care needs to be taken to allow others to enjoy them as well. Some of these monuments are so old and fragile that they are sensitive to the touch of hands or bags and shows. 【4】 This way, you don’t encourage the use of those plastic bags that fly all over many sites.

And here’s the big one—good manners are nearly universal. 【5】 If that doesn’t sound like you, then give the world a break and stay home.

A. Experience the place.

B. Always have a cloth bag with you .

C. Read up on the places you want to visit.

D. Try to buy something from the local stores.

E. A good tourist is polite, positive and eco-sensitive.

F. We’ve cleaned up after ourselves and taken only good memories.

G. If we are good tourists, wherever we go, we try to make it a little better because of our visit.

William Shakespeare, the great English writer of drama(戲劇), was born in 1564 in StartfordonAvon. We do not know everything about Shakepeare's early life. But we know that he studied at the Grammar School in Stratford, and that he became interested in the theatre when he was still a boy.

I took a trip to a big lake in Indonesia with my family two years before. It was really huge lake with beautiful scenery all around. People were amazed by the endless view in front of our eye. Later on, unlike other girls, I was volunteered to go waterskiing alone. I took on the life jacket, got off the motorboat immediately and started my engine as soon as possibly.

The lake seemed broad and endless. I was so exciting to appreciate the beauty of the mountains and waters that I speed my motorboat. Then, after some time, I found me in the middle of the endless lake. I really enjoyed the unforgettable experience!
