How do you feel after you've stayed up late to finish schoolwork? Or the day after a slumber party? Scientists now say that your answers to these questions may depend on your genes.
Genes are stretches of DNA that work like an instruction manual for our cells. Genes tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms. So, for example, certain forms of some genes make your eyes blue. Other versions of those genes make your eyes brown.
In a similar way, new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.
The period3 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 period3. Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers.
Results showed that the people with the short form of period3 performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating.
After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off.
People with the long period3 gene, by contrast, fell asleep in just 8 minutes. They also spent more time in deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form.
1.We can know from the passage that genes can not ________.
A. tell our bodies and brains what to do
B. make our eyes blue or brown
C. decide how well you work without sleep
D. ensure whether you’re good at driving
2.Which of the following statements about the period3 is wrong?

B. can work better than the people with long form of period3 without sleep
C. take less time to fall asleep after they stay up late
D. need more and deeper sleep to keep their brains working at top form

Are you addicted to computer games? Do you stay up all night playing them? Do you feel happy after you play computer games?
There’s no doubt that the excitement and appealing of games these days makes them hard to put down. We are attracted by the choice when it comes to gaming: You can role play—creating your own fantasy characters and stories, giving you a chance to step out of everyday life into an imaginary world. And there are shooting games where you can let out your anger and depression in violent situations where you kill people with guns. You can get excited from the games.
However, can these kinds of games really be fun and can being absorbed in virtual reality be good for us? Should we worry about their effects on our health? Popular games like Grand Theft Auto have been blamed for everything from falling results at school to causing acts of extreme violence. Internet safety adviser, Alan MacKenzie, thinks “any people understandably will just think that a game is just a game and not realizing the exact content that’s in there”. He gives an example of the violence, which he says is “wholly inappropriate for anybody, not to mention children.”
Others will argue that gaming is a harmless form of entertainment. There is evidence that playing video games could actually be good for us. Some games like Game of Thrones and World of Warcraft are educational and using games certainly can help children learn good qualities. Studies have also shown that the skills used in playing games can cause growth in certain areas of the brain, the ability to think in 3D and even improve our eyesight.
Video game players are also no longer just simple creatures. For some, gaming is having a positive effect on their social lives with games like Halo and World of Warcraft often being played in groups. When your group works together to win the game, your sense of achievement is higher than when winning by yourself.
So every coin has two sides. It seems today, gaming isn’t just for game fans and if used in a proper way, we can all take part. If video games have two sides, what side do you stand by?
1.The writer used a lot of questions at the beginning to _______.
A. show his worries about the effect on health
B. lead into the topic of the passage
C. ask the reader for their own opinions about games
D. doubt the advantage of playing computer games
2.Paragraph 3 mainly talks about _______.
A. the contents of the game are complex
B. games contain extreme violence
C. popular games lead to students’ falling results at school
D. gaming is a harmful form of entertainment
3.According to the passage, which of the following shows the good influence on social lives?
A. Han Meimei passed the exam after playing the games.
B. Li Hua leant many English words from playing games.
C. Sunyan worked well with his teammates
D. Yang Li let out his anger and expressions.
4.In Paragraph 4, the author supports his idea _______.
A. by giving some examples
B. with descriptive words
C. by providing some numbers
D. with some research results

When you’ve finished your studies at school and college, do you feel like a well-earned rest? If you’re about to embark on a course at university, you’ll want to recharge your batteries and have some fun. But how long should you do that for? Now the idea of taking a year off before you move into further education seems to be the thing to do.
A year off—also called a gap year—is not a new concept, but there’s now a focus on making the most of this break from academic life. Long gone are the days of just hanging out on a beach or backpacking round the world. While that is still an option, a gap year is now more about gaining skills that will help you in later life. The BBC’s Smart Consumer podcast spoke to a student called Meg, who said “I just always had in the back of my mind I’d spend a year doing something productive and something that would just be good fun.”
Doing something productive is exactly what students are being encouraged to do because doing more purposeful things like work experience or charity work helps them acquire skills to use when competing for a place at university. It looks good on their CV and ultimately makes them more employable.
While the benefits of taking a gap year are clear to see, some students worry they can’t afford it. Another student, Tom, told the BBC that to him, a gap year was an ‘alien concept’. He said “it would have been far too expensive and it’s not something that I would have been able to rely on my parents or family members for.” But some experts say that it needn’t burn a hole in your pocket; you don’t need to travel far and you can even earn money by doing paid work.
For those who do have the funds, a combination of working, volunteering and travelling is undoubtedly an amazing opportunity. It increases confidence and independence, gives you a chance to learn new crafts, and gives you time to contemplate whether university is right for you.
1.What is the new focus of “taking a gap year”?
A.Hanging out on a beach.
B.Backpacking round the world.
C.Spending time trying challenges.
D.Gaining useful skills for future life.
2.Why are students encouraged to do something productive?
A.To make them capable in later life.
B.To get the best result in the competition.
C.To enrich the experience of doing voluntary work.
D.To gain the sense of achievement during the participation.
3.What’s the attitude of some experts towards a gap year?
A.They approve of it. B.They are against it.
C.They are indifferent to it. D.They think it unworthy.
4.What can we infer from the text?
A.You must go to university after taking a gap year.
B.A gap year makes sense if you have the fund to take.
C.All students can afford a gap year if they prefer to.
D.Fund is the most important factor for taking a gap year.
