【题目】American researchers have discovered that human brains and sleep patterns are confused by devices(装置) that give out bright lights. Electronics, such as laptops, mislead our minds into thinking that it is still daytime, preventing sleep and increasing the risk ofinsomnia.

Sleep experts say human's natural body clock begins to rest and relax from the day between 9 and 10 pm but the use of computers confuses it.

A person's brain biologically becomes awake when the sun is out because bright light after dark causes the brain to stop producing the hormone (荷尔蒙) called melatonin that makes us sleepy.

Researchers say blue light from devices such as iPads, which is expected to become a popular reading tool when it comes out later this month, is particularly disruptive (干扰的)during the night when the brain thinks it should be dark.

Experts say a good book is a far better way of resting the brain and ensuring a good night's sleep because the bedside lamp() light doesn't affect the brain as it does not look straight into a person's eyes.

“Potentially, yes, if you're using an iPad or a laptop close to bedtime... that light can be stimulating (刺激) to the brain to make it more awake and delay your ability to sleep” Phyllis Zee, a professor at Northwestern University and director of the school's Centre for Sleep & Circadian Biology, told CNN.

“And I think more importantly, it could also be enough to affect your circadian (昼夜节律的) rhythm. This is the clock in your brain that determines when you sleep and when you wake up. ”

Alon Avidan, associate director of the Sleep Disorders Center at the University of California Los Angeles, added, “I wish people would just take a boring book — an oldfashioned book — and read by a lamp.”

【题目】In a room at Texas Children Cancer Center in Houston, eight-year-old Simran Jatar lay in bed with a drip (点滴) above her to fight her bone cancer. Over her bald (秃的) head, she wore a pink hat that matched her clothes. But the third graders cheery dressing didnt mask her pain and weary(疲倦的) eyes.

Then a visitor showed up. Do you want to write a song? asked Anita Kruse, 49, rolling a cart equipped with an electronic(电子) keyboard, a microphone and speakers(扬声器). Simran stared. Have you ever written a poem? Anita Kruse continued. Well, yes, Simran said.

Within minutes, Simran was reading her poem into the microphone. Some bird soaring through the sky, she said softly. Imagination in its head…” Anita Kruse added piano music, a few warbling (鸣, 唱) birds, and finally the girls voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.

That was the beginning of Anita Kruses project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer(作曲家) and pianist who had performed at the hospital, Kruse said that the idea of how she could help came in one flash.

The effect on the kids has been great. One teenage girl, curling (蜷缩) in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkins disease who rarely spoke surprised his doctors with a song he called I Can Make It.

My time with the kids is heartbreaking because of the severity of their illnesses, says Anita Kruse. But they also make you happy, when the children are smiling, excited to share their CD with their families.

Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the really sweet and nice and loving lady who gave them a shining moment in the dark hour.

【2】What do we know about Anita Kruses project?

A. It helps young patients record songs.

B. It is supported by singers and patients.

C. It aims to replace the medical treatment.

【3】What does the case(实例) of a 12-year-old boy suggest?

A. Most children are naturally fond of music.

B. He was brave enough to put up performance.

C. The project has positive effect on young patients.

D. Singing is the best way to treat some illnesses.

【题目】Camping wild is a wonderful way to experience the natural world and, at its best, it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness, it is becoming more and more important to camp unobtrusively (不引人注目地) and leave no mark.

Wild camping is not permitted in many places, particularly in crowded lowland Britain. Wherever you are, find out about organizations responsible for managing wild spaces, and contact them to find out their policy on camping and shelter building. For example, it is fine to camp wild in remote parts of Scotland, but in England you must ask the landowner’s permission, except in national parks.

Camping is about having relaxation, sleeping outdoors, experiencing bad weather, and making do without modern conveniences. A busy, fully equipped campsite(野营地) seems to go against this, so seek out smaller, more remote places with easy access to open spaces and perhaps beaches. Better still, find a campsite with no road access:walking in makes a real adventure.

Finding the right spot to camp is the first step to guaranteeing a good night’s sleep. Choose a campsite with privacy(隐秘) and minimum(最小的) influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot.

When camping in woodland, avoid standing dead trees, which may fall on a windy night. Avoid animal runs and caves, and possible homes of biting insects. Make sure you have most protection on the windward(迎风的) side. If you make a fire, do so downwind of your shelter. Always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite found, not made—changing it should be unnecessary.

【1】You needn’t ask for permission when camping in________.

A. national parks in England

B. most parts of Scotland

C. crowded lowland Britain

D. most parts of England

【2】The author thinks that a good campsite is one________.

A. with easy access B. used previously(以前)

C. with modern conveniences D. far away from beaches

【3】The last paragraph mainly deals with________.

A. protecting animals

B. building a campfire

C. camping in woodland

D. finding a campsite with privacy

【4】The passage is mainly about________.

A. the protection of campsites

B. the importance of wild camping

C. the human influence on campsites

D. the dos and don’ts of wild camping

【题目】Who hasn't found themselves reaching for the closest food available when they're tired and stressed? More and more research is proving that this isn't all in our mind. Some foods really do lead to a change in our moods (心情)

Carbohydrate (碳水化合物) for calm

This is how some people medicate(治疗) themselves with food — by reaching for cookies or pasta(意大利面食) whenever they're upset. Unfortunately, it doesn't always work. You must eat a meal consisting of 100% carbohydrate, on an empty stomach, to obtain the serotonin (血清素) increase so that you have a good mood.

To get the wishedfor effect, you must not eat anything for four hours and then eat at least 30 grams of straight carbohydrate. Dry cereal (谷类食品), a piece of bread with jam, or a potato should______.

Protein (蛋白质) for power

Of course, sometimes we don't need to be calm and sleepy.Sometimes we need a great deal of mental concentration, so this is when it's important to mix protein and carbohydrate. The protein will prevent the tryptophan (色氨酸) from flooding your brainand the rise in serotonin(血清素) won't occur.

Why dessert makes us happy

Fat and sugar cause the brain to let go endorphins (内啡肽), which send pleasure signals throughout the body. This would be fine, except humans are not particularly good at stopping at one cookie or cake.

You can also satisfy your sweet tooth by choosing fruit for dessert.

Timing your meals for energy

Blood sugar drops after four hours of going without food, causing a decrease(减少) in energy. Eating usually fixes this within 20 to 30 minutes, but don't suppose that eating more will cause a faster increase in energy.

When you eat has as much of an effect on your mood as what you eat. If you regularly go for a long period of time between meals, rethink your schedule and plan ahead.

1The underlined phrase“ do_the_trick”in the third paragraph means ________.

A. be extremely smart

B. intend to cheat someone

C. bring about the desired result

D. do something to amuse people

2The function of protein is ________.

A. to help you keep calm and sleepy

B. to make you feel energetic

C. to lead you to slowness

D. to increase serotonin in your brain

3We can infer from the last two parts that ________.

A. fat and sugar can greatly help people feel happy

B. we humans tend to eat lots of cookies and cakes

C. the more we eat, the faster we will gain energy

D. what we eat is more important than when we eat

4The main idea of the passage is ________.

A. eating for a better mood

B. eating to make you calm

C. eating for more protein

D. eating to make us strong
