A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day.
Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later.
Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack（缺乏）of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on （补充）sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes（糖尿病）. Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick.The underlined word “obese” in the first paragraph may mean .
| A．quite protective | B．very sad |
| C．very fat | D．quite young |
According to Chinese researchers, if a person who lacks sleep can get more sleep during weekends, .
| A．he won’t get hungry easily | B．he will feel tired all the time |
| C．there will be little chance of him becoming fat | |
| D．it will be very hard for him to fall asleep at night |

| B．in the past people didn’t connect sleep with weight |
| C．fat children must have slept less than 10 hours five years ago |
| D．most children are unhealthy because of little sleep |

If you’re making the film with other people, organize your cast and crew effectively. Make sure everybody knows their roles and what day and times they’re needed.
Give people specific jobs so they can become experts in their field. For example, a soundrecordist listens to the sound through headphones as it’s being recorded, and holds an extra microphone if needed.
A camera operator frames the picture(取景), sets focus, checks the light and records the action. The editor “cuts” the picture together after it’s shot.
A producer is the contact point for the film. He or she makes sure crew and cast are there on time, talks to the press and organizes the budget.
A director has to make sure their vision is communicated. To do this everyone needs to be clear about what the director expects from each scene and each shot.
You may also need a make-up-artist, a choreographer, a driver, etc. However, you can quite easily make your first film on your own. Make a schedule that says which shots are to be taken where and when (this is called a shooting schedule) and when you’ve completed a take, cross it off the list. Remember that you may want to shoot “out of sequence”, e.g. shoot the last scene first, and the first last. Similarly if the film begins and ends by a tree in the park, it may make sense to film both scenes while you’re there.
If you’re making animation (动画片), have a space that you can control. You may need extra lights and you may need to leave work in progress. Make sure people living with you are aware what’s happening. Animation needs a lot of undisturbed concentration and patience. Keep at it and it’ll pay off. Aardman and Disney both started off at home experimenting with clay , pens and a camera.From the first two paragraphs we can learn that___________.
| A．every crew member is an expert in his field. |
| B．careful preparations and arrangements are quite necessary. |
| C．both the cast and crew must arrive at the same time every day. |
| D．every person should have his equipment while working together. |
A director knows the purpose of each step of the work, but___________ .
| A．he needn’t tell others about that |
| B．other members just follow his orders |
| C．he must have it known and well understood by others |
| D．others may have their own ideas and special ways of working |
To shoot a film, a shooting schedule must be fixed first ______________.
| A．but it may be crossed off if unnecessary |
| B．but you needn’t work exactly on it |
| C．and each step must be carried out according to it. |
| D．and no one can change it once it is settled |
Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones(黄酮), substances found in cocoa,teaand some kinds of vegetables,may improve age-related memory failure.
Dr. Scott Small is a professor of neurology (神经学) at Columbia University in New York City. He is the leadwriter of a research paper describing the effects of cocoa flavones on brain activity. His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink madefrom cocoa beans or a low-level flavones drink. For a period of three months, somesubjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study. Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memory tests.
The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the leadresearcher of a four-year study involving 18,000 adults. This study will use flavones capsules. The studysubjects will be divided into two groups and will take two pills per day. The capsules used will all look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo（安慰剂）.
Dr. Manson says it's not necessary for people to start eating more chocolate, because 3 persons would have to eat a huge amount of chocolate to get the same level of flavones given to the rest subjects. He adds many manufacturers have planned to remove the flavonesfromtheir chocolate products. Similarly, Dr. Manson says a cocoa-based flavones extract（提取）maybe developed in the future But he says that more studies are needed to see how much flavones is good for our health.What was done to thesubjects after Dr. Small's study?
| A．They were asked to take a high-level flavones drink. |
| B．They were given brain imaging and memory tests. |
| C．They were given capsules containing flavones. |
| D．They were asked to take two pills of flavones capsules per day. |
What's the similarity of the two experiments?
| A．Both use high-level flavones capsules. |
| B．The number of the subjects is the same. |
| C．Drinks and placebos are used in both experiments. |
| D．Thesubjects are divided into two groups in both experiments. |
Why will Dr. Manson carry out the four-year study?
| A．To carry out the experiment further. |
| B．To prove the first experiment is wrong. |
| C．To test how much flavones can improve our memory. |
| D．To show eating chocolate is better to improve memory. |
What can we learnfromthe last paragraph?
| A．It's not necessary for us to eat chocolate. |
| B．In the future we can get flavones without eating chocolate. |
| C．The more we eat flavones, the better our healthwill be. |
| D．It's easy for people to get the same level of flavones given to the test subjects. |
“Well, I finally did it. I finally decided to enter the digital age and get a cell phone. My kids have been annoying me and the last straw was when my car broke down, and I was stuck by the highway for an hour before someone stopped to help. But when I went to the cell phone store, I almost changed my mind. The phones all have cameras, computers and a “globalpositioning” something or other that's supposed to spot me from space. Goodness, all I want to do is to be able to talk to my grandkids! The people at the store weren't much help. They couldn't understand why someone wouldn't want a phone the size of a postage stamp. And the rate plans! They were confusing, and expensive…and the contract (合同) lasted for two years! I'd almost given up until a friend told me about her new Jitterbug phone. Now, I have the convenience and safety of being about to stay in touch with a phone I can actually use.”
Affordable plans that I can understand—and no contract to sign! Unlike other cell phones, Jitterbug has plans that make sense. Why should I pay for minutes I'm never going to use? And if I do talk more than I plan, I won't find myself with no minutes like my friend who has a prepaid phone. Best of all, there is no contract to sign—so I'm not locked in for years at a time. The USbased customer service is second to none. And the phone gets service anywhere in the country.

A paperclip，made of steel wire bent into a looped (环形的)shape，is an instrument used to hold sheets of paper together．This common device is a wonder of simplicity and function．But where did this simple，cheap，and practical invention come from?
In the late 19th century，the most common way to hold papers together was by using a pin．Although the pin was an inexpensive tool and was easily removable，it would 1eave holes in the paper. Later，as steel wire became more common，inventors began to notice its elastic(有弹性的)feature. With this feature，it could be stretched and twisted into various clip—like objects．In the years just before 1900，quite a few paperclip designs appeared．The name most frequently associated with the paperclip invention is Johan Vaaler，a Norwegian inventor. However, Vaaler’s clips were not the same as the paperclips currently in use．Specifically，they did not have the inside loop we see today．The familiar looped design was invented by Gem Manufacturing Ltd．in England．This clip is therefore sometimes known as the Gem clip．
Because of Vaaler，the paperclip played an important historical role in Norway．During World War II，Norway was occupied by the Nazis．Norwegians were prohibited from wearing any symbol of their national unity(团结)，such as buttons with the initials of their king．Thus，in protest，they started wearing paperclips to show their unity．The reason for doing this was simple：Paperclips were a Norwegian invention whose original function was to bind together．After the war，a giant paperclip statue was put up in Oslo to honour Vaaler—even though his design was never actually produced．According to the first paragraph，the paperclip is________．
| A．made of paper |
| B．shaped like a pin |
| C．inexpensive and useful |
| D．for holding clothes together |
One way the paperclip is better than the pin is that_________
| A．it is cheaper |
| B．it is simpler |
| C．it can be removed more easily |
| D．it doesn’t damage the paper |
Which of the following best shows what the Gem clip looks like?
The last paragraph is mainly about_________．
| A．how Vaaler’s clip became a national symbol |
| B．how widely used Vaaler’s clip is |
| C．how the Nazis ruled the Norwegian people |
| D．why Norwegians had the initials of their king on their buttons |

Peng Liyuan，wife of President Xi Jinping, has drawn extensive attention from people both at home and abroad for her charisma and grace. Accompanying her husband on his first overseas trip after becoming president, Peng Liyuan exhibited graceful demeanor, a pleasant personality and well-chosen dress, prompting people to coin the term “Liyuan style”.
Peng Liyuan, as one of China’s best-known singers, was popular among Chinese people long before her husband became the president. Loved by her fans, she has been in touch with the people for years.
“Liyuan style” is not only representative of a fashion idol, but also overpass cultural and diplomatic barriers. The beautiful handbags Peng has carried, and the plain but elegant and delicate dresses she has worn have become popular. Her choice of clothing, made-in-China instead of luxurious foreign brands, shows her belief in domestic dress designs.
But “Liyuan style” is not only about clothing and a woman’s paraphernalia. It is also about diplomacy and promoting China’s soft power. In Moscow, Peng visited a boarding school for orphans and children estranged（疏远）from their parents, encouraging them to strive for a better life, which brought out the maternal side of her character. In Tanzania, she donated sewing machines and school bags to women and children. And as a World Health Organization ambassador in the fight against AIDS, Peng is devoted to many public causes, including those relating to charity and healthcare.
Some observers have already started saying that Peng’s activities have become part of public diplomacy in China.
Also, “Liyuan style” has boosted the confidence of the Chinese people. Modern but not flashy, elegant but not arrogant, Peng has all the virtues of a Chinese woman and carries them to the international stage.
Since the 18th Party Congress and the annual sessions of the NPC and CPPCC, the country’s new leadership has vowed to adopt a down-to-earth work style to connect with the people. Peng’s plain but elegant style shows that thriftiness and an earthy style need not be drab and boring.
So it can be said that Peng’s first appearance on the international stage has kicked off well.What’s the meaning of the underlined word “paraphernalia”?
| A．Her self-charm |
| B．Things she carried with |
| C．Her diplomatic measures |
| D．Her support to her husband |
This passage is mainly about__________.
| A．President Xi’s wife Peng |
| B．Peng Liyuan’s charming character |
| C．the achievements of Peng on charity and healthcare. |
| D．a cultural phenomenon named as “Liyuan style” |
Which of the following statements is TRUE?
| A．“Liyuan style” is only a fashion idol. |
| B．Peng Liyuan, as the wife of President Xi, admires lots of luxurious brands. |
| C．Peng Liyuan is willing to fight against AIDS and become an ambassador of WHO. |
| D．Peng firstly appears in the pubic as the “First Lady” in Moscow. |
