For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.

In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.

However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.

“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls，” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, self­harm, low concentration and poor performance at school，” she added.

While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.

Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.

1.According to the passage, we can know ________.

A．it's a good habit to play with smartphones or iPads late into night

B．scientists suggest we should avoid using smartphones or iPads

C．darkness makes a great impact on the amount of melatonin

D．the sun was the only source of light in ancient times

the sun was the main source of light.”可知D项为错误结论。

2.Which of the following is TRUE according to the passage?

A．The darker it is, the more melatonin will be produced.

B．The lighter it is, the more melatonin will be produced.

C．The more melatonin you have, the worse you'll sleep.

D．The more electrical equipment you have, the more melatonin will be produced.

3.The underlined part in Paragraph 4 refers to those ________.

A．who are young adults or adolescents

B．who don't perform well in school

C．who are addicted to a television or laptop

D．who are short of sleep at night and perform poorly in daily life

4.In the writer's opinion, which is a correct suggestion?

A．You should go to bed when the sun goes down.

B．You should use an orange or red light electronic screen.

C．You should wear a pair of blue sunglasses when sleeping.

D．You should avoid blue light as possible as you can before bedtime.

Dear Sirs，

Your shipment(装运)of twelve thousand“Smart”watches was received by our company this morning．However，we wish to make a number of complaints concerning the serious delay in delivery and your failure to carry out our instructions．

It was stressed from the beginning that the delivery date had to be less than six weeks. While we appreciate that delays in production are occasionally unavoidable．We must point out that the major reason why the order was placed with your company was that we were assured by you that your existing stocks ensure immediate shipment．Late delivery of the goods has caused us to disappoint several of our most valued customers．and is sure to have a negative effect on future orders．

The second complaint concerns the difference in colour．Only half the watches in the delivery received are of the colours we ordered．Our Hong Kong agent assures us that she stressed to you the importance of following our instructions．Since we consider there to be only a limited market in this country for watches of other colours．Any watches that are not of the specified colours will , of course, be returned to you．

We are also somewhat concerned about the rather poor quality of the goods received．since it is obvious that the watches that finally arrived have been produced from inferior materials and have been made to a lower standard than those in the sample．We have also found that a number of the watches do not appear to be functioning．We should like to point out that we feel this matter to be entirely your responsibility．

As a result of the above problems，therefore，we feel that the most suitable course of action is to return to you unpaid any of the goods considered unsatisfactory，and to deduct(扣除)any costs from our final settlement．We shall also be forced to reconsider whether any further orders should be placed with your company.

We look forward to your immediate reply．

Yours sincerely，

John Smith

Nowadays, many of us spend about 10 hours a day in front of a Computer or other electronic devices and less than 30 minutes a day outdoors. The result is that our Brain easily feels tired. We need to give the brain a rest, but how?

David Strayer is a professor of psychology at the University of Utah. He claims that camping may be just what a tech-tired brain needs. His argument finds strong support from Carl and Kate, two experienced campers. Carl, who works for a mobile phone company, says that being outdoors makes him feel relaxed. It also prepares him for the work he must do. "Camping gives us a chance to be in touch with nature and it's very relaxing. When you return to work on Monday, you're in a better state of mind. I really like the way I feel on Monday. Kate is a senior editor. She says camping brings her some peace she couldn't have otherwise. She even finds herself more creative.

David Strayer explains that camping allows close contact with nature and being in nature calms the brain and helps it to focus. When people go camping, they need to learn about animals and natural environments; they have to deal with the weather, learn to stay dry in the rain or warm in the snow and have to keep the feet in good condition when hiking and walking.

Some might say that taking a long walk in the woods or by the ocean or in a city park is wonderful, too. But camping requires that one spend more time in nature and it can test him in different ways. And it brings more health benefit as well.

1.What is the result of using electronic devices too much?

A. We will waste time.　　 B. Our brain will feel tired.

C. Our study will be influenced.　　 D. Our brain will be refreshed.

2.How does Carl feel after camping?

A. Warm　　 B. Calm

C. Relaxed　　 D. Peaceful

3.Why does the author take Carl and Kate as examples?

A. To share a good camping site.　　 B. To share their work experiences.

C. To show their interest in camping.　　 D. To show advantages of camping

4.Which of the following is the benefit of camping?

A. It helps protect the environment.　　 B. It helps us learn more about nature.

C. It teaches us to keep warm in the rain.　　 D. It teaches us to avoid difficult situations.

5.What is the author’s attitude towards camping?
