When I was a little boy, I would play outside for hours on sunny summer days and then have a deep and peaceful sleep at night. Sometimes, I’d have some vivid dreams, making me for a moment. I would stare out into the darkness to see if anything was there and then over and go back to sleep. I can still remember a few times when I woke up, out into the darkness, and actually someone there. It was Mom over me as I slept. Each time she told me to go back to sleep and I closed my eyes again, feeling and loved.

Everybody sleeps, but what people stay up late to catch—or wake up early in order not to miss—varies by culture. From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

Around the world, people changed sleep patterns thanks to the start or end of daylight savings time. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to “winter time”starting on October 36.

Russia’s other late nights and early mornings generally correspond to public holidays. On New Year’s Eve, Russians have the world’s latest bedtime, hitting the hay at around 3:30 am.

Russians also get up an hour later on International Women’s Day, the day for treating and celebrating female relatives.

Similarly, Americans’ late nights late mornings, and longest sleeps fall on three-day weekends.

Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey(冰球)final.

The World Cup is also chiefly responsible for sleep deprivation(剥夺), The worst night for sleep in the U.K. was the night of the England-Italy match on June 15. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.

It should be made clear that not everyone has a device to record their sleep patterns, in some of these nations, it’s likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that’s the case, though, the above findings are still striking, If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?

1.What does the author say about people’s sleeping habits?

A. They are culture-related .

B. They affect people’s health

C.They change with the seasons.

D.They vary from person to person.

2.What do we learn about the Russians regarding sleep?

A. They don’t sleep much on weekends.

B. They get less sleep on public holidays

C.They don’t fall asleep until very late.

D.They sleep longer than people elsewhere.

3.What is the most probable reason for some rich people to use a device to record their patterns?

A. They are involved in a sleep research.

B. They have trouble falling asleep.

C. They want to get sufficient sleep.

D. They want to go to bed on regular hours.

4. What does the author imply in the last paragraph?

A. Sleeplessness does harm to people’s health.

B. Few people really know the importance of sleep.

C. It is important to study our sleep patterns.

D.Average people probably sleep less than the rich.

Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer?

People have been wondering why elephants do not develop cancer, even though they have life spans(寿命)that are similar to humans, living for around 50 to 70 years.

Now scientists believe they know why. A team at the University of Chicago, Us has found that elephants carry a large number of genes that stop tumors(肿瘤)from developing. To be precise, they found 20 copies of an anti-tumor gene called TP 53 in elephants. Most other species, humans included, only carry one copy.

According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal’s sensitivity to DNA damage. This lets the cells(细胞)quickly kill themselves when damaged before they can form deadly tumors.

“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals,” study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous, large creatures with long life spans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.

This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto’s paradox”. Evolutionary biologists believe it results from larger animals using protection that many smaller do not, In the elephant’s case, the making of TP53 is nature’s way of keeping this species alive.

The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.

“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.

“It’s up to us to learn how different animals tackle(对付)the problem so we can use those strategies to prevent cancer in people.”

Alexis,17,sat quietly in the passenger seat of her dad's car.She let her eyes lazily scan the landscape for wildlife.Then a deer came into view about 200 yards in front of them."Dad,there's a deer there!" Alexis said.It was a male deer with sharp antlers (角) on each side of its head.

As the car moved closer,Alexis saw that the deer's head was bent toward the ground.Then she heard a scream and saw an arm fly up near the deer's head.Alexis realized the deer was attacking a woman.Sue,a 44-year-old mother,had been out for her morning run.The deer followed her and edged closer."I knew I was in trouble," Sue says.She went to pick up a stick for self-defense,and the deer charged.It lifted her with its antlers and threw her into the air.Sue could feel blood flew down her leg.Within seconds,the deer had pushed her off the road.

When Alexis and her father pulled up,the deer was throwing Sue like a doll.Alexis looked into the woman's terrified eyes,and before her father had even stopped the car,the teenager jumped quickly out of the car and ran toward the deer."I was kicking it to get its attention," she says.Then her father,who had followed his daughter,pushed the deer away from the women.

Turning the hammer around,Alexis closed her eyes and beat the deer's neck with all her strength.When she opened her eyes,the deer was running away.Alexis got in the driver's seat and sped toward the nearest hospital.

Let's say you want to hit the gym more regularly this year. How do you make that happen? Consider putting the habit loop to use.

Here's how it works:

A habit is a 3-step process. First, there's a cue, something that tells your brain to operate automatically. Then there's a routine. And finally, a reward, which helps your brain learn to desire the behavior. It's what you can use to create-or break-habits of your own.

Here's how to apply it:

Choose a cue, like leaving your running shoes by the door, then pick a reward---say, a piece of chocolate when you get home from the gym. That way, the cue and the reward become interconnected. Finally, when you see the shoes, your brain will start longing for the reward, which will make it easier to work out day after day. The best part? In a couple of weeks, you won't need the chocolate at all. Your brain will come to see the workout itself as the reward. Which is the whole point, right?

1.Which of the following best fits in the box with a “?” in THE HABIT LOOP?

A. Pick a new cue.

B. Form a new habit.

C. Choose a new reward.

D. Design a new resolution.

2.What's the purpose of putting the habit loop to use?

A. To test out different kinds of cues.

B. To do something as a habit even without rewards.

C. To work out the best New Year's resolution.

D. To motivate yourself with satisfactory rewards

3.“This year when I see the Harry Potter poster, I will read 30 pages of an English novel or an English newspaper in order to watch TV for half an hour." What is the cue in this resolution?

A. The Harry Potter poster.

B. Reading 30 pages of an English novel.

C. An English newspaper.

D. Watching TV for half an hour.
