More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night’s sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends.

Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen.

Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, “Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed.”

They wrote in the journal Applied Ergonomics(应用人类工程学) that iPad makers should adjust the spectral power distribution(光谱功率分布) of the devices so that they affect the sleep patterns of users less.

It is not just a good night’s sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.

A. it is the same as daylight which keeps people awake

2.The underlined phrase “dim the display” means ____.

A. keep away from the display

D. turn off the display

A. warn of the seriousness of long-term poor sleep

B. call on researchers to study sleep patterns

C. show the danger of obesity and cancers

D. show how sleep is harmed by using iPads too much

4.What’s the main idea of the passage?

The world is becoming more and more connected, but many people feel lonely in the midst of it. You might not feel lonely right now, but there might be times when you do. Here are some tips on dealing with loneliness:

Be positive about yourself. 1. If you constantly think of yourself as ugly, mean, or unattractive, then it will be difficult for you to connect with others. You must accept yourself before you can accept others. It’s common that you might have some negative qualities. So does everyone else. So in order to get rid of loneliness, you should focus on your positive side and think of yourself in a positive way.

Have an attitude of gratitude (感恩).2. It’s easy to focus on the negatives in life, but don’t forget that there are also many positives. Remember them and be thankful. What does this have to do with loneliness? Well, if you are grateful, then you will become cheerful.3. See the positive side of others. Just as you should see the positive side of yourself, you should also see the positive side of others. Everyone has shortcomings, but everyone also has a positive side.4. That will make you like them and make it easier for you to connect with them.

5. The more you think about yourself, the more likely it is for you to have a pity party and feel lonely. For example, you might think that nobody likes you or cares about you. So it’s important that you shift your attention away from yourself. It can be as simple as smiling at your neighbors or holding a door for a stranger.

The world has a fast growing population and people need more land for houses, factories, highways, and so on. The farmland is decreasing with each passing day. How to meet the need of feeding the growing population? One way is to introduce some high-output gene into a crop to enable it to produce more. Biologists over the years have discovered genes which can raise output of the crops, resist pests, improve taste, etc.

However, in many western countries there is widespread concern over the safety of “Genetically Modified”(GM) (转基因) foods, because they think there may be serious problems of environment, health, safety, morality and so on.

As a scientist I must admit GM foods involve great risks to humans. In fact in Europe they’re called “Frankenstein foods” by many. Frankenstein is a character in a novel. He was a very clever scientist. He created a monster(怪物), which eventually killed him.

Soybeans can be made into many foods. However, it’s hard to trace them. Therefore, it’s very important we have to make sure the soybean, if genetically modified, is free from any poisonous matter harmful to human beings. For this we need very good testing. We do have some testing on some animals, but no completely satisfactory testing has ever been made so far. They’re entirely new, and their problems are entirely unknown. It takes time to develop persuasive tests to know whether they’re harmful to us or not.

We may not be able to tell what may happen if we take GM foods. Some of them may be resistant to antibiotics (抗生素). Then many of the medicines we have today will have no effect on people eating GM foods.

A more likely case is the GM foods may contain genes some people are allergic to.

GM products have already come into our lives but most people even know nothing about it. At least we have to be clear about what we are eating. The China Consumers Association is calling for labeling (标注) on GM foods so that consumers will know before they buy them.

1.From the passage we can infer that _____.

A. Frankenstein foods can make people clever

B.B.GM foods are very popular in Europe

C. many Europeans reject GM foods

D. Frankenstein was a scientist creating GM foods

2.The underlined phrase “trace them” in Paragraph 4 probably means“　　　　 ”.

A. find their market 　　　　　　 B. raise their quality

C .find their origins 　　　　　 D. enjoy their taste

3.Which of the following is TRUE about GM foods?

A. The testing shows GM soybean foods are free from poisonous matter.

B. Sometimes consumers can hardly tell GM soybeans from natural ones.

C.GM foods prove to be safe to humans after some testing on animals.

D.GM foods problems have been known after testing on animals.

4.What can we learn from the passage?

A.GM foods make antibiotics fail to function properly.

B. People eating GM foods will suffer from food allergies.

C.People should be informed of which foods are GM foods.

D.As GM foods are safe at present, they’re certainly safe later on.

高二英语单项填空简单题查看答案及解析

With these increased pressures and difficulty in ensuring a graduate job, more people are turning to recruitment(招聘) agencies for help. Luke Harper wrote for the Independent warning students to be cautious when using graduate recruitment agencies in their job hunt. The article’s main argument against graduate recruitment agencies is that they are looking to sign people up to the agency and harvest data, without having any real intention to personally find them a job.

The fundamental problem with this approach is a basic misunderstanding of how the recruitment part works. One of the more common ways is that recruitment agencies aim to find you a job to secure a fee from their clients（客户）. Recruitment agencies operate as a business, not a careers service and are not expected to find you a job while you wait around.

There is no denying that among the recruitment agencies, there are some CV(简历) hungry, cut and shut agencies that are uninterested in the candidates they have on their books. However, nowadays these are in the minority and don’t tend to last very long.

Paul Farrer, Chief Executive of a leading recruitment agency is worried that a few bad apples are ruining the reputation of what is an excellent part. Farrer said “The trouble with such an imbalanced and misleading article is that some graduates may now be put off approaching recruitment agencies who may well be able to help them.”

Professionals in the industry are cautious of how some of the less respectable agencies operate. Earnest（认真的） recruiters believe that graduates should be aware that some of these agencies will take on graduates for all their details rather than helping them find a job, like Harper mentioned. To fight this, Farrar advises that “Graduates should have a simple checklist before approaching any agency. Has the agency taken the time to talk to me? Have they invited me to a face-to-face meeting? Have they guaranteed not to forward my CV to any employer without my permission? These three steps will safeguard every application.”

Farrer also pointed out that that is not the only safety net that graduates can rely on. He said “Graduates can also check to see if the agencies are members of either APSC or the REC, the two trade bodies they can make an official complaint to. The vast majority of recruitment agencies are professional organizations that help place thousands of graduates every year and poorly researched articles help no one.”

1.The main purpose of this passage is _______________ graduate recruitment agencies.

A. to advise readers to be cautious of

B. to argue against some misjudgment against

C. to explain why there is a prejudice against

D. to seek the solutions to the problems caused by

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

A. Luke Harper holds the same idea about jobs with Paul Farrer.

B. Recruitment agencies actually do the same work as a careers service.

C. Job hunters’ detailed information is of value to recruitment agencies.

D. A member of APSC or the REC will not cheat its clients.

3.What advice does Paul Farrer give graduates to avoid less respectable agencies?

A. Consulting professionals before giving their personal details to an agency.

B. Making a face-to-face investigation into an agency before approaching it.

C. Guaranteeing that the agency will not forward their CV to any employer.

D. Selecting some agencies that are monitored by official trade bodies.

4.What is the author’s attitude towards graduate recruitment agencies?

A. Neutral.　 B. Positive.

C. Negative.　　 D. Not Clear.
