As digital technology increasingly controls the lives of young people, scientists have begun to wonder: Is the Internet good or bad for kids?
“It’s impossible to answer that question because the Internet is so many things,” says psychologist Patricia Greenfield. “It’s networked computer games and news about politics and instant messaging and e-mails to your grandmother. It can be both an educational resource and a hiding place for kidnappers.”
Adults have many reasons to worry about kids’ Internet use. In chat rooms, for instance, it is easy to lie and kids can get trapped in dangerous situations. In searching for and visiting websites, kids can come across words and pictures that they may not be prepared for. To help prevent that situation, in 2000, the US Congress passed the Children’s Internet Protection Act, which requires schools to block offensive and obscene（淫秽的）websites.
Researches have pointed out how confusing the Internet can be for children, even when they think they know how it works. To find out how much kids know about the technology, Zheng Yan, an educational professor in New York, interviews over 300 students in grades four to eight. Most of the youngest students think the Internet is simply an icon (图标) on the screen. It often isn’t until 10 that kids realize that the Internet is a network of millions of computers. It takes another 2 or 3 years for them to understand that a stranger can see what they’ve posted.
Understanding the technology helps kids understand how dangerous the web can be. It’s not simply enough to block harmful websites or to limit the number of hours kids spend online. Learning about the Internet can also give young people the power to use it in beneficial ways.By saying “the Internet is so many things”, Patricia Greenfield means that ______.
| A．computer technology is hard for people to master |
| B．computers have more disadvantages than expected |
| C．computers have more advantages than expected |
| D．computers bring advantages as well as disadvantages |

If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal(内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes(糖尿病). They want to prove that internal fat damages the body’s communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no shortcut. Exercise has to be an important part of your lifestyle.” Bell said.What is the passage mainly about?
| A．Internal fat is of no importance. |
| B．Thin people may be fat inside. |
| C．Internal fat leads to many diseases. |
| D．Thin people don’t have diabetes. |
According to the passage, which of the following is WRONG?
| A．Exercise can help to reduce the internal fat. |
| B．People can get rid of internal fat by improving diet. |
| C．People with heart disease all have internal fat. |
| D．Men are more likely to have too much internal fat. |
From the last paragraph, we can find that ______.
| A．exercise plays an important role in people’s life for keeping healthy |
| B．thin people usually have internal fat even if they are slim |
| C．it is easier to burn off internal fat than external fat |
| D．internal fat leading to disease has been proved |
Does handwriting matter? Not very much, according to many educators. However, scientists say it is far too soon to declare handwriting is not important. New evidence suggests that the link between handwriting and educational development is deep.
Children not only learn to read more quickly when they first learn to write by hand, but they are also better able to create ideas and remember information. In other words, it’s not only what we write that matters — but how.
A study led by Karin James, a psychologist at Indiana University, gave support to that view. A group of children, who had not learned to read and write, were offered a letter or a shape on a card and asked to copy it in one of three ways: draw the image on a page but with a dotted outline（虚线）, draw it on a piece of blank white paper, or type it on a computer. Then the researchers put the children in a brain scanner and showed them the image again.
It was found that when children had drawn a letter freehand without a dotted outline or a computer, the activity in three areas of the brain were increased. These three areas work actively in adults when they read and write. By contrast, children who chose the other two ways showed no such effect. Dr. James attributes the differences to the process of free handwriting: Not only must we first plan and take action in a way but we are also likely to produce a result that is variable. Those are not necessary when we have an outline.
It’s time for educators to change their mind and pay more attention to children’s handwriting.What do scientists mean by saying “it is far too soon to declare handwriting is not important”?
| A．Handwriting is not very important to children. |
| B．Handwriting should not be ignored at present. |
| C．Handwriting has nothing to do with education. |
| D．Handwriting can not be learned in a short time. |
Which is NOT the children’s task in the experiment?
| A．Copy the image on a page but with a dotted outline. |
| B．Draw the image on a piece of blank white paper. |
| C．Put a brain scanner and show the image again. |
| D．Type the image directly on a computer. |
What does “that view” in Para. 3 refer to?
| A．How we write is as important as what we write. |
| B．A group of students should know what to write. |
| C．Children create ideas and remember information. |
| D．Children read quickly when they write by hand. |
According to the passage, the author obviously _______ giving up handwriting.
| A．is for | B．doesn’t care about |
| C．is responsible for | D．is against |

I was going to die in Antarctica, I was certain. A picture of my frost-covered body, pale and lifeless, filled my mind as I glanced around. In all directions spreads the empty wilderness of Antarctica, the only feature being the division between snow and sky. I sadly stared at my team, who were rapidly disappearing from my sight．
It happened in the year 2009 when I was head of an adventure attempting to reach the South Pole. The team was made up of ordinary women from all around the world—from Jamaica, India, Singapore and Cyprus—many of whom had never seen snow, or spent a night in a tent, before we set off. Our aim was to be the most international all-female team to reach the South Pole．
By the time I realized that my sledge was firmly stuck, the team were already a long way ahead of me. I called out to Era, my teammate from Brunei, who was next in line. Getting no response, I called again, but my shouts were carried away in the opposite direction by the wind. I had stood and watched the line for a while as it marched away from me, confident that at any moment one of my teammates would look behind her. Seconds passed. Nothing. I was gradually being left alone．
I pushed my sledge again, my strength suddenly increased when I thought of a cold, lonely death. This time the sledge moved a little. I kicked at the ice with my ski-pole and boot, desperately trying to break the sledge free and pushed again. The sledge shot forward, knocking me off balance. I struggled to my feet and set off after the team．
I caught up just as they realized I wasn't there. As we continued, my panic slowly faded. I found myself laughing to myself as I noticed Reena checking behind her every few paces. In fact for the whole of the rest of the day each member of the team glanced over her shoulder every few minutes. They were not going to risk losing me again.What can we know from the first paragraph?
| A．The author's poor physical condition． |
| B．The wonderful sights of Antarctica． |
| C．The rough natural conditions of Antarctica． |
| D．The author's regret of being left alone． |
What's the main idea of the second paragraph?
| A．Brief introduction about the adventure. |
| B．How the author became the team leader. |
| C．The process of selecting the team members. |
| D．Complete information about the team members. |
What made it possible for the author to get her sledge out of the ice?
| A．The shouts of her teammates. |
| B．The strong desire to live on. |
| C．A sudden change in wind direction. |
| D．The natural beauty ahead in Antarctica. |
Why did the team form the habit of looking behind?
| A．Because they were expecting their team leader's arrival. |
| B．Because their team leader demanded them to do so. |
| C．Because they were afraid there might be danger coming from behind. |
| D．Because they wanted to make sure their team leader was following. |
In the US, people prefer waiting for a table to sitting with people they don’t know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don’t know, it is impolite to light up a cigarette without asking if it will disturb them.
At American restaurants and coffee shops you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill.
Most cities and towns have no rules about opening and closing time for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day.
Serving in restaurants is often large, too large for many people. If you can’t finish your meal but would like to enjoy the food later, ask your waitress or waiter for a “doggie bag”. It may have a picture of a dog on it, but everybody knows you’re taking the food for yourself.
Supper and dinner are both words for the evening meal. Some people have “Sunday dinner”. This is an especially big noon meal.
Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.Which statement is true?
| A．American people like sitting with people they don’t know. |
| B．A hostess always seats a small group at a large table. |
| C．American people never sit with people they don’t know. |
| D．American people will not light a cigarette if the people who sit at the same table mind their smoking. |
What is served before you order?
| A．Bread. | B．Butter. | C．Coffee. | D．Cold water. |
What do American people always do when servings are too large for them?
| A．They take the food home with a “doggie bag” for their dogs. |
| B．They leave the food on the table and go away. |
| C．They take the food home with a “doggie bag” and enjoy the food later. |
| D．They ask the waitress or waiter to keep the food for them. |
What can you learn about “tips” according to the passage?
| A．Customers often add tips to their check. |
| B．The price of the meal usually includes the tip. |
| C．People are not expected to pay tips in addition. |
| D．Tips are supposed to be left on the table when customers leave |
