How do you feel after you"ve stayed up late to finish schoolwork? Or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes.
New research suggests that a gene called “period 3” affects how well you function without sleep.The “period 3” gene comes in two forms：short and long.Everyone has two copies of the gene.So, you may have two longs, two shorts, or one of each.Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of “period 3”．Study participants had to stay awake 40 hours straight.Then，they took tests that measured how quickly they pushed a button when numbers flashed on screen and how well they could remember lists of numbers.
Results showed that the people with the short form of “period 3” performed much better on these tests than the people with the long form did.In both groups，people performed worst in the early morning.
After the first round of experiments，participants were finally allowed to sleep.People in the group that performed well on the tests (those with the short form of “period 3”) took about 18 minutes to nod off.
People with the long “period 3” gene, by contrast, fell asleep in just 8 minutes.They also spent more time on deep sleep.That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form of“period 3”．What about you?

What else do kids get out of camp? Plenty!
Kids who want to be stars on the football field or basketball court have their choice of a variety of summer camps. Some, such as the Let Me Play sessions offered by Nike, are free and provide a few hours of instruction by professional athletes. Other summer sports camp opportunities are offered by professional teams or university athletic departments. Players and coaches usually lead those camps, teaching basic skills as well as teamwork and good sports behavior.
Open up to fun
It’s easy to be yourself if you have something in common with your fellow campers, even when that something is a disease.
A journal entry by one camper describes the camp’s high ropes course as a symbol of everyone there and the challenges they face. “Climbing it and going through that struggle to get up and push yourself is like getting through the sickness we all were faced with at some point,” she writes. There is another reward that comes once climbers reach the top of the ropes course and hear the words “good job” from their fellow campers. It is, “in a way, coming close to being cured. Even if we aren’t, it felt like it,” the camper says.
Healthy benefits
There are also health and wellness camps for kids who don’t have any illnesses. For Erin H. of Oklahoma, the first thoughts she had about going to a weight-loss camp were that it would be embarrassing and a waste of time. But as soon as she arrived at Wellspring Adventure Camp, she knew it would be awesome. “I had the most fun ever!” says Erin, who liked Wellspring so much. She stayed for eight weeks instead of the four weeks she’d originally agreed to. “This camp has helped improve my self-respect 100 percent, and I’m no longer self-conscious.”
小题1:The first paragraph serves as _________.
| A．conclusion | B．definition (下定义) |
| C．background | D．comment (评论) |
| A．Setting a goal | B．Developing an ability |
| C．Killing time | D．Forming a habit |
| A．it was an effective way to cure campers’ illness |
| B．it had campers know the difficulty to fight against illness |
| C．it made campers realize the importance of health |
| D．it helped campers feel better about their illness |
| A．gained a lot from the weight-loss camp |
| B．stayed in the weight-loss camp for four weeks |
| C．thought taking part in the weight-loss camp was useless |
| D．felt embarrassed about her appearance now |
| A．give advice on how to choose a suitable camp |
| B．compare sleep-away camps and day camps |

| D．introduce the benefits of going to a camp |
South Korea produces all types of entertainment, the most popular being music, soap operas and films. What makes Hallyu so hot in Asia? One reason is that its products are of high quality and much cheaper than western products. Another reason is that eastern cultures are similar to each other, although there are language differences.
Korean pop music, or “K-pop”, ranks the first everywhere. Fans love the songs and the attractive stars. Companies like SM Entertainment, JYP Entertainment and YG Entertainment help many K-pop stars, such as Super Junior, Big Bang and Rain, to succeed. They are not only popular in Asia but also enjoy popularity in the West. In 2011, Big Bang’s mini-album Tonight reached the top 10 on U.S. Tunes Top Pop Albums. When SM Entertainment took their 2010 world tour to Los Angeles, only 30 percent of the 15,000 fans were Korean. Half of the audience wasn’t even Asian!
One important reason for the success of Hallyu is simply the Internet. A little more than 10 years ago, Korean soap operas, movies and music reached the outside world quite slowly. They began in Korea, and then gradually spread outward, appearing in its neighboring countries where local TV and radio companies would play them. Now they are played around the world online at the same time.
YouTube is another major way to get Korean entertainment to fans everywhere. It is an inexpensive and valid way for artists to introduce their work to a larger audience. In 2010 the YouTube channels for the top three Korean entertainment groups together had nearly 800 million views from 225 different countries.
小题1:Hallyu is very hot in Asia partly because________.
| A．languages in Asia are similar to each other |
| B．the culture is the most fashionable in the world |
| C．South Korea’s products are the cheapest in Asia |
| D．the quality of South Korea’s products is high |
| A．by giving examples |
| B．in order of space |
| C．by listing reasons |
| D．in order of time |
| A．how important the Internet is |
| B．Hallyu is popular worldwide |
| C．the Internet helps Hallyu spread quickly |
| D．how popular and effective YouTube is |
| A．slow | B．useless |
| C．successful | D．necessary |
| A．K-pop Ranks the First Everywhere |
| B．Hallyu Makes Waves across the World |
| C．YouTube Helps Korean Cultures Spread |
| D．Korean Soap Operas Are Growing in Popularity |
Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings（包装）， that blue foods are considered not agreeable to the taste, and that cosmetics（化妆品） should never be packed in brown. Their discoveries have grown into a whole subject of color psychology（心理学）。 Some of our preferences（偏爱） for colors are clearly psychological. Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement. Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people’s mind. People in bright red surroundings show an increase in breathing speed, heartbeat and blood pressure; red is exciting. Pure blue has exactly the opposite effect; it is a calming color. Being exciting, red was chosen as the signal for danger, but a close study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars.
小题1:. The passage tells us that salesmen have __________.
| A．discovered the relationship between color and psychology |
| B．tried out colors on blind people |
| C．found out that color affect sales |
| D．developed a special subject of color psychology |
| A．what color we prefer depends on our state of mind |
| B．foods sell well in green or blue wrappings |
| C．blind people cannot sense color difference |
| D．a bright yellow has exactly the opposite effect to red |
| A．their blood pressure rises |
| B．they want to taste blue foods |
| C．they will feel like buying things |
| D．they won’t easily feel nervous |
| A．Colors and sales | B．Colors and feelings |
| C．The blind and colors | D．Preferences for colors |
The Manchester project is one of the biggest smart card schemes in the world. Every time people use the cards on a bus or train, the fare is deducted (reduced) from the value of the card. When they have no credit left, the cards can be recharged at a local shop.
A smart card looks just like a normal plastic card but it has a silicon chip in it. It is possible for the same silicon chip to perform a number of different functions, so one plastic card in your pocket could do a large number of different jobs. The card has much more memory space than a magnetic-strip card, so many more things can be recorded on it.There are two types of smart cards. One is the contact card which is used in the same way as a magnetic-strip card.
Information is transferred by running the card through a narrow opening in an electronic reader. In the slot, electronic probes make contact with the magnetic-strip or silicon ship and read the information. The other type is the contactless smart card where the electronic reader communicates with the card by short-range radio waves. This makes the card quicker and more convenient to use because it does not have to leave your wallet. It is also more reliable as it is not easily influenced by scratches or dirt. However, the biggest advantage that smart cards have over magnetic-strip cards is that they are more secure. They are much more difficult to make than conventional cards and they have to be made by specially trained manufacturers. In addition, they have a large number of extra security features on them and if a smart card gets lost or stolen a quick phone-call to the distributor ensures that its individual number is made invalid and unreadable. This can be done more quickly than with a magnetic-strip card.
小题1:A smart credit card can do many kinds of jobs because ____ .
| A．it is smart | B．it is a plastic card |
| C．it has a silicon chip in it | D．it can be recharged |
| A．the card can be put into a new charge of electricity |
| B．the cards can be changed into new ones |
| C．the cards can be put to use again |
| D．the cards can be recycled |
| A．they can store more information | B．they are more secure |
| C．they are more convenient to use | D．all of the above |
| A．Contactless cards are more convenient to use than contact ones |
| B．Smart cards are more expensive to manufacturer |
| C．By means of long-range radio waves contactless cards can communicate with the electronic reader |
| D．A smart credit card and a normal plastic card are the same thing |
