The traditional American school year begins in late August or early September.It ends in May or June, followed by summer vacation. 1.___ Because long ago, young people had to help their families harvest summer crops. At least this is what people today may think.

2.__ A recent report from an education policy center at Indiana University explored the historical roots of the traditional school calendar.

In the early days of the United States, children were not required to attend school School calendars depended on local needs. 3.__ They worked on family farms during the other months. City schools were often open much longer, some for eleven months of the year.

After the Civil War, more and more people saw the need for a system of required education.__ 4.______Many city schools wanted a shorter year and a longer summer break. The schools were often crowded. There was no modern air conditioning. Hot days would make it difficult to learn. Many rural educators, however, pushed for a longer school year. They thought it would keep children safe from industrial dangers when there were few child-labor laws.

So the traditional school calendar was a compromise (折中). The average school year used to be one hundred and seventy days. Times have not changed much. 5.___ But some experts think the traditional school calendar needs to change because the needs of the nation have changed.

A year ago, I paid no attention to English idioms, though my teacher emphasized the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.

One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished gently shaking his head, shrugging his shoulders, saying, “You don’t say!” “You don’t say!” I was puzzled. I thought, perhaps this is not an appropriate topic. “Well, I’d better change the topic.” So I said to him, “Well, shall we talk about the Great Wall By the way, have you ever been there. “Certainly, everyone back home will laugh at me if I leave China without seeing it. It is magnificent.” He was deep in thought when I began to talk like a tourist guide, “The Great Wall is one of the wonders in the world. We are very proud of it.” Soon I was interrupted again by his order, “You don’t say!” I couldn’t help asking. I said, “Didn’t you say you don’t say” Hearing this, the Englishman laughed to tears. He began to explain, “You don’t say actually means really It is an expression of surprise. Perhaps you don’t pay attention to English idioms.” Only then did I realize I had made a fool of myself. Since then, I have been more careful with idiomatic expressions.

You get anxious if there’s no wi-fi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you’re not there. All these can be called “always on” stress caused by smart phone addiction(上瘾).

For some people, smart phones have freed them from the nine-to-five work. Flexible working has given them more autonomy (自主权) in their working lives and enabled them to spend more time with their friends and families. For many others, though, smart phones have become cruel masters in their pockets, never allowing them to turn them off and relax.

Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they’re spending on the device(设备) and set up warnings if the usage limits are broken. “Moment’s goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”

Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘always on’ culture are that your mind is never resting, and you’re not giving your body time to recover, so you’re always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”

And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (瘫痪) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they’re controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.

1.What’s the first paragraph mainly about?

A. The popularity of smart phones.

B. The progress of modern technology.

C. The signs of “always on” stress.

D. The cause of smart phone addiction.

2.Kevin Holesh developed Moment to_______.

A. research how people use their mobile phones

B. help people control their use of mobile phones

C. make people better use mobile phones

D. increase the fun of using mobile phones

3.What’s Dr. Christine Grant’s attitude towards “always on” culture?

A. Confused. B. Positive.

C. Doubtful. D. Critical.

4.According to the last paragraph, a greater amount of data means_______.

A. we will become less productive

B. we can make a decision more quickly

C. we will be equipped with more knowledge

D. we can work more effectively

There’s a whole lot of things that people fill their stomachs with. Some of them keep people alive. Some of them taste good to people. Some of them help people win pie-eating contests. Alcohol does none of these things. Why do people keep drinking it? And what does it do once it gets to their stomachs?

There are all kinds of alcohol molecules (分子), but the one that people most often pour down their throat is ethanol (乙醇). Ethanol is very tiny and it dissolves in water, so it gets into all sorts of places that it’s not supposed to. Alcohol heads for the digestive system. Because it dissolves in water, it can get into the water in the bloodstream. Because ethanol, to a certain extent, can pass through cell membranes(膜). It can go almost anywhere. It spreads through the muscles, and is sweated(出汗) — unmetabolized(未经新陈代谢的) and whole — through the skin. It gets into the heart. It even takes a walk through the brain, and this is the secret of its powers.

Alcohol depresses the nerves, and the nerves affect almost every area of the body. Enough alcohol makes people sleep, so people who become unconscious choke on their own vomit (呕吐物). Most worryingly, enough alcohol can shut down those parts of the brain just like any other parts. People become unconscious and their brains simply forget to breathe.

Alcohol is broken down in the liver. Alcohol doesn’t destroy the liver, but products that the liver breaks the alcohol into do cause damage. A glass of wine per day can not do any harm. Instead, it can prevent heart attacks or can make someone functionally young. And it is kind of nice to know that sometimes, relaxation and cheer can be bottled. All that’s needed is to take care how much alcohol is let into a person’s brain.

1.How does the author introduce the topic of the text?

A. By statement.B. By question.

C. By arguing.D. By explaining.

2.Why can alcohol reach the brain?

A. Because it can move through water molecules in the blood.

B. Because it is small enough to get through any narrow space.

C. Because it is so light that the bloodstream can transport.

D. Because it is absorbed only by the cells in the stomach.

3.What’s the main idea of Paragraph 3?

A. Alcohol affects the work of the nerves.

B. Alcohol has an effect on people’s breath.

C. People are drunk when their brains get drunk.

D. Drinking too much is quite dangerous.

4.From the passage, we can know ________.

A. many people like a drink when they feel relaxed

B. enough alcohol can control the brain activities

C. alcohol damages the liver indirectly

D. proper alcohol may lead to better sleep
