Some people can stay up all night and still get work done the next day. I’m not one of them. After a night without enough sleep, I feel bad-tempered. I have trouble remembering things. And all I want to do is go to bed.

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” influences 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 (参与者) had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed (闪过) on a 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.

While people with the long “period 3” gene 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?

1.The purpose of this passage might be ___________

A.    to tell us the importance of plenty of sleep.

B.    to tell the result of a research on sleepy gene.

C.     to inform the harm of lacking sleep.

D.    to announce the sleeping rules of humans.

2.What kind of people need less sleep according to the research?

A.    Those with two short copies of the gene.

B. Those with two long copies of the gene.

C. Those with one short and one long copy of the gene.

D. Those with three short copies of the gene.

3.If one lacks enough sleep, one should avoid doing important or dangerous things ___________.

A. at noon               B. at night

C. in the afternoon           D. at dawn

4.Why did the writer think he or she had the long form of “period 3”?

A.    Because the writer could remain energetic without enough sleep.

B. Because the writer could do things correctly at dawn.

C. Because the writer needed more sleep to keep energetic.

D. Because the writer recovered quickly after sleep.

The Notre Dame (巴黎圣母院) fire has been put out, but its spire (尖顶) and a large portion of its wooden roof have been damaged. The terrible destruction causes a sudden sharp pain to people around the world. “What a pity that we cannot see the damaged parts of the wonder anymore.”

But the good news is that there is at least one way of seeing them, namely through a video game called Assassin’s Creed: Unity. In this game, the player can travel to one city after another and enter the buildings exactly like what they are in reality, and see Notre Dame as it was before the fire. Further, with virtual reality technology, which is already quite mature, one can even look around the undamaged Notre Dame as if it is still there. Maybe digital technology could help to better protect architectural cultural heritage.

The idea of making digital models of ancient buildings to save their data dates back to the 1990s and the necessary technology has continued to advance since then. By scanning the ancient buildings with lasers, building 3D models with multiple images, as well as measuring everything precisely, engineers can make a copy as accurate as the real one.

As computers and smartphones are hugely popular, the digital model has great useful value. First, it allows tourists to feel the cultural relics without touching them. The virtual tour of Dunhuang Grottoes in Gansu Province is a good example of this as tourists can view the paintings without standing near them. Furthermore, it can make the digitized cultural relics more famous by spreading awareness about them via the Internet. In 2000, a virtual tour of the Great Wall became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting the site in the following years. Above all, it preserves all the information of the cultural relics.

Of course, however precise a model is, it is not the original. Maybe we will have better technologies in the future, but the digital technology offers a practical way to preserve architectural cultural heritage at the moment.

1.What can we see about Notre Dame in the game?

A.The damaged Notre Dame. B.Its wooden shape.

C.The big fire. D.Its original look.

2.What will engineers do to create a digital copy of the ancient buildings?

A.Build 3D models of full size. B.Scan the photos of the buildings

C.Measure all the parts exactly. D.Improve the technology needed.

3.How does the author prove the digital copy has vital practical importance?

A.By giving examples. B.By classification.

C.By comparison. D.By listing data.

4.What is the author’s attitude towards the application of the technology?

A.Delighted B.Supportive

C.Doubtful D.Conservative

If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do?

Natural noise from　 waves, wind,　 rain and even earthquakes is common in oceans. Unfortunately, man­made noise from oil and gas drilling, sonar, and ships is also present.

Low frequency noise has doubled off the California coast every decade since the nineteen sixties.　 The　 main　 reasons　 are ships' propellers (螺旋桨). They not only generate continuous low frequency sound, some propellers　 cavitate(形成气穴), which means they create air bubbles that collapse, creating loud popping sounds.

Whales　 use　 low　 frequency　 calls　 to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods.　 Endangered　 humpback　 and　 right　 whales, which use fibrous baleen to strain　 food from the water, are the most at risk.

Scientists studying right whales off Canada's east coast have discovered that whales are sending louder calls through the water to make themselves heard.　 Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area.　 This could seriously affect survival of this already threatened species.

Scientists don't have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels,　 they　 are　 creating　 sound　 maps. They hope to get shipping lanes moved so　 that the noise pollution ships create will not overlap with areas most important to the whales.

1.What does the passage mainly talk about?

A. Whales are in danger because of the noise.

B. Noise pollution is affecting whales.

C. Natural noise is good for whales.

D. How to protect whales endangered.

2.The following statements are true EXCEPT ________.

A. You can call the police if you are disturbed by a noisy neighbor.

B. Low frequency noise has doubled off the Canadian coast every decade since the 1960s.

C. Noise pollution can prevent whales from contacting each other and from locating prey.

D. Endangered humpback and right whales are the most at risk.

3.We can infer from the last paragraph that ________.

A. some areas important to whales are overlapped with the ship lanes

B. scientists are creating the sound maps by tracking ships and marine mammals

C. if scientists have guns, they can correct the noise pollution

D. scientists have worked out a plan to protect the whales

4.According to scientists，________.

A. right whales off the Californian coast have been in danger because of the loss of the energy

B. right whales cannot find food and mate for they lose a lot of living area

C. there are about 20% of the normal communication areas still available for the right whales

D. the right whales always invest most of their energy for making calls

We all know the hard work that filmmakers and actors put in to provide us with entertainment.

1.

For decades now, film studios have used so-called test screenings to get feedback from members of the public before a movie comes out. 2.　 However, media giant Disney has come up with a more high-tech solution: to measure test audiences’ reactions by using special cameras placed inside cinemas.

Pairing the cameras with custom software, the company can track what each audience member is feeling at any point in the movie, from anger to joy. 3.　 The cameras can see in the dark, and the software can figure out a person’s mood based on the slightest of facial expressions. It’s hoped that this new method will allow more detailed feedback from test audiences because it can accurately read their reactions in real-time.

Test screening are highly valued in the movie industry. 4.　 Viewers of E.T. the Extra-Terrestrial (1982) would have left the cinema feeling a whole lot different if it weren’t for its test audience’s feedback. “In one cut of the film that was tested, E. T. died instead of going home in his spaceship. You won’t be surprised to hear that the test audience in question didn’t warm to this ending at all.” wrote media website Den of Geek.

But for those who are concerned about privacy, the cameras won’t be installed in public cinemas.

5.

A. In reality, not all of the people are content with the effect of the movies.

B. This works by mapping 68 different points on each audience member’s face.

C. And several well-known movies have been greatly changed following feedback.

D. The special cameras in public cinemas easily go wrong and often fail to work.

E. After all, unless you’re part of a test audience, being in front of the cameras is best left to the movie stars.

F. But it seems that even regular moviegoers like us have a big impact on how a movie turns out too.

G. Test audience members are usually asked to fill in a questionnaire after a screening, telling the film studio what they liked and didn’t like.
