There are two kinds of memory: short-term and long-term. Information in long-term memory can be remembered at a later time when it is needed. The information may be kept for days or weeks. However, information in short-term memory is kept for only a few seconds, usually by repeating the information over and over. The following experiment shows how short-term memory has been studied.

Henning studied how students who are learning English as a second language remember vocabulary. The subjects in his experiment were 75 college students. They represented all levels of ability in English: beginning, intermediate (中等), and native speaking students.

To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered. Each question had four choices. The subjects had to circle the word they had heard in the recording, some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Finally the subjects took a language proficiency test.

Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning's results suggest that beginning students hold the sound of words in their short-term memory, and advanced students hold the meaning of words in their short-term memory.

1. Which of the following statements is TRUE according to the passage?
A.Henning gave a separate test on vocabulary to his students.
B.Long-term memory can be achieved only by training.
C.It is easier to test short-term memory than long-term memory.
D.Information in short-term memory is different from that in long-term memory.
2. The word "subject" in the passage means _________.
A.the theme of listening materialB.the student experimented on
C.a branch of knowledge studiedD.a native speaker
3. From Henning's result we can see that ________.
A.advanced students always remember words by their meaning
B.beginners have difficulty distinguishing the pronunciation of words
C.it is difficult to remember words that sound alike
D.it is difficult to remember words that have the same meaning
4. The passage centers on ________.
A.an experiment on studentsB.two kinds of memory
C.short-term memoryD.memory

【推荐1】Have you ever wondered if you see the same colors as other people?Most people know what blue is when they see it. They call it “blue” because they were taught the word and connected in with what they saw. But how do you know what you see as blue isn’t someone else’s red?

The ability to perceive (感知) different colors is up to receptors (接受器) in our eyes. Light waves hit these receptors and they react depending on which colour the light is, sending signals to the brain. The brain then reads these signals to determine which colour light the eyes are receiving.

Some people’s receptors are more developed than others. The inability of the receptor to feel the light waves correctly means that some people cannot tell the differences between similar colors. Those with more developed receptors can see more colors. We sometimes hear people having an argument about whether something is dark blue or black. It might be because one person has stronger receptors to feel the light waves than another.

In the past, most scientists would argue that everyone saw colors in the same way. However, research was conducted on monkeys, in which their receptors were changed. This enabled them to see more colors than usual. Normally monkeys can only see blue and green, but the change allowed them to see red. Their brains automatically pot used to new colors. This suggests that our brains nay find new colors of the things we see. Colors could be a very personal experience, unique to everyone.

So, the next time you talk about your favourite colour, just remember if yours is blue and your friend says red, you two might actually be thinking about the same colour. What if everyone in the world has the same favourite colour, but just calls it different names?

1. What is Paragraph 2 mainly about?
A.How we perceive colors.
B.What the brain does with signals.
C.The inability to see colors.
D.The connection between receptors and light waves.
2. Which of the following might the author agree with?
A.Some people cannot feel colors with their developed receptors.
B.People with poor receptors usually have colour weakness.
C.The more lights people feel, the weaker receptors they have.
D.People who have strong receptors can see: dark blue.
3. What’s the purpose of conducting the research on monkeys?
A.To lest the monkeys with colors.
B.To develop the receptors of humans.
C.To prove everyone sees colors in a different way.
D.To enable monkeys to find more colors.
4. Where does the text probably come from?
A.An art journal.B.A film review.C.A business newspaper.D.A science magazine.

文章大意:本文是一篇说明文,主要讲的是防蓝光眼镜对缓解数字屏幕造成的眼睛疲劳可能没用,但可能有助于睡眠。

【推荐2】Our screens give out all kinds of light, especially blue light. Blue light, the argument goes, can affect your eye health, your sleeping patterns, and your health. Blue light glasses—technically they should be called “blue light blocking glasses”— filter out (过滤) blue light, letting in the other wavelengths of light, thus theoretically reducing the danger that blue light presents. Blue light glasses are designed to reduce what’s known as digital eye strain (疲劳), or DES. There are many symptoms associated with DES, including headaches, dry eyes, and unclear vision.

How effective are blue light glasses? We’ll start with the bad news: there is no evidence that blue light glasses have any effect on eye strain from digital screens. In fact, one British glasses dealer was fined for indicating that blue light glasses can protect against DES, given that there’s no scientific evidence of this. What’s more likely is that DES is caused by overuse, or misuse of eyes. After all, the sun is a substantially more powerful provider of blue light than our screens, and it has been decidedly proved that DES isn’t associated with the sun at all. The general agreement is that DES is caused by spending too long, staring too hard, and sitting too close to our screens. Health experts generally recommend taking breaks to prevent DES, rather than relying on blue light glasses.

But there is one thing that blue light glasses might help with. Some studies have indicated that blue light can be bad for our circadian rhythms (生理节奏). In other words, exposure to blue light could make it harder to fall asleep. There haven’t been enough studies to tell if blue light glasses, worn for a few hours before bed, could help you sleep better, but it’s not out of the question.

That said, there are interesting reports of people loving their blue light glasses. Even if it’s just the placebo (安慰剂) effect, that can be incredibly powerful, and if it works on you, keep doing it.

1. What can we know from Paragraphs 1 and 2?
A.Blue light is beneficial to health.B.It’s advisable to take breaks to prevent DES.
C.Blue light glasses can protect against DES.D.Blue light mainly comes from the screens.
2. What is DES likely caused by?
A.Poor-quality sunglasses.B.Improper use of eyes.
C.The blinding sunlight.D.The small size of screens.
3. What can we know about blue light glasses from Paragraph 3?
A.They reduce eye strain.B.They affect circadian rhythms.
C.They may be helpful for sleep.D.They help to see things more clearly.
4. What is the author’s attitude to blue light glasses?
A.Objective.B.Opposed.C.Indifferent.D.Unclear.

【推荐3】Promotion at work can be good for the pocket.However,it can also be very risky for a person's mental health,according to British researchers from the University of Warwick in Coventry.

The new findings go strongly against the common belief that advancement in a career can result in better health because of an increased sense of self­confidence,life control and overall well­being(幸福感 ).“Getting a promotion at work is   not as great as many people may think.Our research finds that the   mental health of managers typically deteriorates after a job promotion and goes beyond merely a short­term change in a way,”said Chris Boyce, the researcher of the University of Warwick.He   also added   that   they could   not find any health   benefits   in individuals who had had job promotions.Instead,these people   don't go to hospital to have health checks as often as they should,which may be something to worry about rather than celebrate.

To find out whether there is a connection between job   advancement and physical health,Boyce and his team used data   from the British Household Panel Survey.The data contained   information on nearly 1,000 recently promoted individuals in the   United Kingdom.And the data contained information on many   aspects of life,including work and self­reported health.After analyzing all the available information,they discovered that there was no evidence of improved physical health after a job promotion.

However,what the researchers did find was evidence of   greater mental stress.The experts found that promotion gives   people,on average,10 percent more mental stress and up to 20 percent less time to visit their doctors in the event of illness.Matt   Smith,a Scottish health expert,said mental stress is caused by working long hours.He said,“When someone is promoted there   might be even more pressure to work longer hours and therefore they can't afford the time to care about their health.”

1. According to the text we can learn that work promotion________.
A.is traditionally believed to be harmful to people's health
B.decreases people's self­confidence and happiness
C.gives people more chances to have health checks
D.can help raise people's income to some extent
2. The underlined word “deteriorates” in the second paragraph means “becomes___”.
A.satisfyingB.doubtful
C.optimisticD.worse
3. What do we know from Boyce's research?
A.It analyzed many aspects of the promoted individuals' lives.
B.It surveyed 1,000 people in the world.
C.It showed how people gained work promotion.
D.It proved that work promotion may lead to a short­term change in health.
4. From the last paragragh we can learn that________.
A.people who are promoted suffer from increased mental stress
B.the work after promotion will take up 20 percent of people's leisure time
C.promoted individuals tend to pay more attention to their health
D.poor health condition makes promoted individuals feel stressed
5. What is the best title for this text?
A.Work Promotion Helps Increase Self­Confidence.
B.Work Promotion Is Actually Bad for One's Health.
C.Work Promotion Means Having to Work Harder.
D.Work Promotion Brings Wealth and Health.
