“Don’t tell anyone”.We hear these words when someone tells a secret to us.1. We’re often tempted to(忍不住的) “spill the beans”, even if we regret it later.

Shah explained that people often feel that it will help them keep a person as a Mend.Another reason people share secrets is guilt over keeping it from someone close to them.A sense of distrust can develop when people who are close do not share it with each other. “Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone, ”according to Shah.

He added that talkative people could let secrets slip out.4. A quiet person may be someone who keeps everything inside.To tell such a person a secret may cause them stress, and make them talk about the secret.

Shah said that to judge whether to tell someone a secret, you’d better put yourself in their position.Think about how you would feel to be told that you mustn’t give the information away.Shah also recommended that if you accidentally give up someone’s secret you should come clean about it.5.

When it comes to creativity，one of our biggest concerns is usually how we can be more creative, or how to come up with better ideas. I've gathered some of the most practical studies to help improve creativity.1.

Many people think that happiness is the ideal state to create something. Recently a study on creativity made a great conclusion. 2.I don't want you to put yourself in a bad mood to create something, but next time you're in strong feeling, try to sit down and focus that energy on creating something.

3.Reading or feeling absurd ( or dreamlike) things can help boost( 促进) pattern recognition and creative thinking. Because the mind is always seeking to make sense of the things that it sees, and such objects put it in"overdrive" while the mind tries to work out exactly what it is looking at or reading. I like reading interesting short stories like The Last Question when looking for inspiration.

You can also get moving, because it's suggested that exercise can actually improve creative thinking as well, due to its ability to get the heart pumping and put people in a positive mood. 4. I's not necessarily the act; it's the change in moods. f you’re stuck in a creative job and want to take a break, try exercise while your brain is subconsciously at work. 5. I tend to jogging outdoors in this case，and it's truly helpful for me.

A.Why not stick to reading?

B.Experiencing something unreasonable works.

C.It may help to speed up your " Aha!" moment.

D.Creativity increases when whatever feelings run high.

E.Try a few out for yourself and see which ones work best.

F.It can produce more creative thoughts just like thinking about love.

G.We are in two very different states of mind when trying to create something.

They tell us when to get up or when we’re running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body’s own internal clock---have a powerful influence on our health and behaviour. They are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns.

In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music.

The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib（撒小谎） in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end.

“The body clock has a great effect on us all,” says Professor Jim Horne from the Sleep Research Centre at Loughborough University. “Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That’s because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece.”

So what effects do circadian rhythms have and what’s the best time of day to take advantage of them?

1.The underlined word “They” in the first paragraph refers to　　　　　　　 .

A. our clocks                B. scientists and experts

C. our daily routines        D. circadian rhythms

2.The research referred to in Paragraph 3 found that people tend to　　　　　　　 .

A. tell lies when they are tired

B. tell lies if they are rewarded

C. lose temper as they become tired

D. break down because they are tired

3. According to the passage, when are people most quick-thinking?

A. In the morning.                B. Around midday.

C. In the late afternoon.        D. In the early evening.

4.What information will the writer probably present following the last paragraph?

A. Some practical suggestions to prevent people from lying.

B. Examples of how the human body clocks control the body.

C. Examples of the most suitable time to do different activities.

D. An explanation of how the human body clock controls the body.

5. What is the best title for the passage?

A. Rebuild your body clock            B. Timing is everything

C. Sleep more, lie less                D. Your time is limited

高三英语阅读理解中等难度题查看答案及解析

When we go out traveling,we need either a map or GPS to point us in the right direction.But bumblebees（大黄蜂）have neither of these things,yet they still know the best route.Why is that?

It turns out that these hard-working little bees try many possible passages before picking out the best one and remembering it the next time they journey out.They learn from“trial and error”,according to a study by scientists from the University of London.

We use it all the time in our daily lives—trial and error is a helpful problem-solving method.It is the basic concept of“learning from your mistakes”.Most of the time,we fail on our first try,so we analyze the failure,make adjustments and try again.After repeating this a few times,we finally get things right.

This might sound a bit tiring,but it’s certainly effective and it works for bumblebees.

In the study,scientists set up five artificial flowers in a field.Each one of them was fitted with motion-triggered（运动触发的）cameras and had landing platforms with drops of sugar in the middle to attract the bees.

At first,scientists noticed the bees’ flying routes were long and complex.But after they gained enough experience,they gradually got to their destination quicker.Every time a bee tried a new route that was shorter than the route it had tried before,it was likely to use it again.Otherwise the new route would simply be given up and another one was tested.

“The speed at which they learn through trial and error is quite extraordinary for bumblebees,as this complex behavior was thought to be one that only larger-brained animals have,”Professor Lars Chittka,leader of the study,told Sciencedaily.com.

In fact,the smart bumblebees don’t try every possible route.Normally,they would only try about 20 out of the 120 possible routes to visit the flowers.

More interestingly,scientists found that if they removed a flower,bees would continue looking at that location,even if it has been empty for a long time.“It seems bees don’t easily forget a fruitful flower,”Chittka said.

1.The bumblebees are good at finding the best route because ________.

A. they have relatively smaller brains

B. their body parts function like GPS

C. they try out different routes and remember the best ones

D. they take the trouble of testing every possible route

2.The author explains the bumblebees’ behavior of trial and error by ________.

A. using numbers　　 B. making a metaphor（比喻）

C. making comparisons　　 D. talking about human behavior

3.The study led by professor Lars Chittka suggests that ________.

A. bumblebees try to keep their flying routes long and complex

B. every new route the bumblebees take is shorter than the one they take before

C. bumblebees are familiar with every flying route they have taken before

D. scientists find it unbelievable that bumblebees learn from their mistakes so quickly

4.What is the main point of the article?

A. Bumblebees are as smart as large-brained animals.

B. Trial and error is an effective way to solve our daily problems.

C. A new discovery about how bumblebees find the best routes through trial and error.

D. How bumblebees remember the best routes,small as their brains are.

When most of us look at our hands, we might notice that we need to clean, or stop biting our fingernails, and that’s about it. But if you ask a doctor, he can see a whole lot more. Everything from poor diet and stress to serious kidney (肾) problems can be revealed by a glance at your fingernails.

There are about 30 different nail signs that can be associated with medical issues, though may indicate more than one problem, according to Dr.Amy Derick, a clinical instructor of dermatology at Northwestern University.

Here are five of the things a doctor can tell about your health based on your fingernails.

1. People who aren’t eating well and lack vitamin or dietary may have thinner than normal nails, which are more likely to break.

2.Horizontal (水平的) lines are associated with serious physical stress. They frequently occur in people who have gone through chemotherapy(化疗).They can also occur after some illnesses, injuries, or with severe malnourishment(营养不良).Interestingly, there may be an altitude connection too. They’ve also been found in people who dove 1,000 feet and others who participated in an Everest exploration.

3. Vertical （垂直的）lines, however, are generally not such a big deal. Some people are more genetically prone to them than others, but they’re commonly associated with aging.

4. When people lack iron, their nails can turn spoon-like. Instead of curving down and covering the finger normally, they ’ll start to rise up on the sides and front, like the part of a spoon that holds liquid.

5. Kidney and liver problems can create “half-and-half nails”, where one part of the nail is white and the other part dark or pink, according to Derick.

Doctors note that because disease diagnosis is complex and some symptoms can be associated with different diseases, you should always see a medical professional if you are concerned about something you notice.

1. What is the main idea of the passage?

A. Doctors can tell us something about our health by looking at our nails.

B. We should see a doctor if we find nails in bad condition.

C. A famous doctor in the USA conducted an interesting research.

D. If we don’t want to get ill, we need to clean and stop biting our fingernails.

2. If we don’t eat well or regularly, our fingernails may ________.

A. become harder than normal nails.

B. become thinner than normal nails.

C. become “half-and-half” nails.

D. have horizontal and vertical lines.

3.Who will have horizontal lines on the nails ?

A. A cancer patient who has received normal treatment.

B. Hungry African children suffering from severe malnourishment.

C. An explorer who had reached Zhangjiajie in Hunan Province.

D. A patient with serious illness, like kidney and liver problems.

4. Which of the following best describes the nails that show people lack iron?

A. The nails are thinner and more likely to break.

B. The nails will curve down and cover the fingers.

C. The nails will start to rise up on the sides and front.

D. The nails will change their colours on the surface.
