You may say that rain comes from clouds, but you can also say that rain is clouds.1., you should know the mechanism through which water moves from the Earth to the atmosphere and back again.

Dew point is the temperature at which water vapor begins to condense (凝结) and becomes water droplets that can fall as rain. Dew point can vary anywhere from the 30s (Fahrenheit) to, on rare occasions, the 80s.

2.. Once the air has cooled past the “dew point", it condenses around a nucleus, which are usually tiny particles of dust, smoke or even salt that are floating in the air. Then tiny water droplets are formed.3.. If you pay close attention to clouds in the sky, you'll see char they’re constantly shrinking and growing,

Water vapor that has formed clouds is on its way to becoming rain, bur it's not there yet. For now, the water droplets are 80 tiny that the air currents keep them in the air, just as swirling particles of dust can stay in the air.4..

When water droplets combine with one another, they become heavier than the uplift of the air around them. Eventually they fall down through the cloud as rain.5.They attract more water vapor to themselves and grow quickly until they're heavy enough to fall as snow.

A.Rain cloud is formed when there is enough water in the air

B.As warm air rises with the water vapor it contains, it cools

C.If you are curious about what kind of cloud will become rain

D.Sometimes the droplets rise high enough to freeze into ice crystals.

E.The tiny water droplets that initially form are what you see as clouds

F.If you want a better understanding of why rain comes down from clouds

G.As those droplets continue to rise, they have two ways to come back to Earth

Can you escape from a sinking vehicle? The answer is obviously yes. “But you’ve got to be quick.” said Gordon Greisbeck, a professor from the University of Manitoba’s. Here he gives four rules of survival.

Rule 1. Don’t call 911 until you are out of the car. You should get out of that vehicle immediately after unbuckling. Think about calling 911 once you’ve made it out alive. ‘Time is very important,” Greisbeck says, “If you touch your cell phone, you’re probably going to die.”

Rule 2. Don’t open the door. Roll down or break the windows instead. Opening the door is very difficult against the water pressure and it also allows so much water into the vehicle that it will speed up the sinking process. Since most vehicles now have electronically controlled windows, it is probable that the circuits (电路) will short before you have a chance to roll them down. So you’ll need a tool like the Life Hammer to break the windows open. And make sure these tools are within reach at all times.

Rule 3. Children first. Everybody should get out of their own window if possible, but the kids are going to have a harder time fighting through the rush of water, so push them out if you have to. Greisbeck suggests starting with the oldest kids and taking the youngest out in your arms.

Rule 4. Get out. Swim through the broken windows as fast as possible. You can’t imagine what will happen in the next second. Any intention to take your belongings can be deadly.

If you’ve failed to get the windows rolled down or broken, you’ll still have the slightest of chances to escape. Once water fills the car, the pressure will be equalized and you will be able to open the door. But to do this, you will also have to be expert at holding your breath in an extremely stressful situation.

Studies show that you may be lied to every day anywhere from 10 to 200 times. We say, “Nice song.” “Honey, you don’t look fat in that, no.” But another study showed that strangers lied three times within the first 10 minutes of meeting each other. We lie more to strangers than we lie to coworkers. Men lie eight times more about themselves than they do other people. Women lie more to protect other people. If you’re married, you’re going to lie to your wife/ husband in one out of every 10 communications. If you’re unmarried, that number drops to three. But look, if at some point you got lied to, it’s because you agreed to get lied to. Truth about lying: lying’s a cooperative act. Not all lies are harmful. Sometimes we’re willing to lie for the sake of social dignity (尊严), maybe to keep a private secret.

Lying is complex. It’s woven into the fabric of our daily and business lives. We’re deeply disturbed by the truth. We explain it, sometimes for very good reasons, other times just because we don’t understand the gaps between ideals and realities in our lives. We’re against lying, but secretly we’re for it in ways that our society has practiced for centuries and centuries. It’s as old as breathing. It’s part of our culture and history. Think the stories from Dante, Shakespeare, the Bible, News of the World.

Lying has great value to the evolution of human being. Researchers have long known that the more intelligent the species, the more likely it is to lie. We human like to become leaders. It starts really early. How early? Well, babies will pretend to cry, pause, wait to see who’s coming and then go right back to crying. One-year-olds learn hiding truth. Two-year-olds bluff (虚张声势). Five-year-olds lie outright and try to control via flattery (讨好). Nine-year-olds, masters of covering up. By the time you enter college, you’re going to lie to your mom in one out of every five interactions. By the time we enter this work world to be breadwinners, we’ve entered a world that is just full of fake digital friends, business media, identity thieves, world-class cheats, ——in short, a post-truth society.

What do you do? Well there are steps we can take to guide our way through the bushes. Trained lie spotters get to the truth 90% of the time. The rest of us, we’re only 54% accurate. Why is it so easy to learn? There are clever liars and stupid liars. There’re no real original liars. We all make the same mistakes. We all use the same techniques.

1. From Para.1 we learn that lying is very ________.

A. harmful　　 B. easy

C. interesting　　 D. common

2.According to the passage, a lie works when _________.

A. the liar’s words are sweet enough

B. it is given to a complete stranger

C. someone gives the liar cooperation

D. we are willing to lie for the dignity

3.Lying is complex because ________.

A. it is practiced by clever ones

B. people are for it as well as against it

C. ancient stories are full of lies

D. it is the whole part of great culture

4. The examples of kids lying in the passage show ________.

A. lying is a sign of intelligent development

B. lying is good for children’s growing up

C. at what age children begin to tell lies

D. 9-year-old children are masters of lying

5.What will the writer most likely talk about if he continues the passage?

A. How to become clever liars.

B. How to avoid stupid lies.

C. How to get through the bushes.

D. How to tell truth from lies.

高三英语完形填空中等难度题查看答案及解析

They say that sticks and stones may break your bones, but words will never hurt you. Yet childhood bullying (欺凌) really can damage your long-term health. Gone are the days when bullying was considered an unavoidable and finally harmless part of growing up — just last month we learned that childhood bullying can lead to poorer mental health even into middle age.

Now William Copeland at Duke University in Durham, North Carolina, and his colleagues have shown that it can have lasting physiological effects too. They tracked 1,420 nine-year-olds right through their teens. Each child was seen up to nine times during the study and asked about bullying. The team then measured levels of C-reactive protein (CRP) in their blood. CRP is a marker of inflammation (炎症) linked to higher risk of cardiovascular disease (心血管疾病) and problems like diabetes. “Because we were collecting biological samples throughout, we were able to look at CRP levels in subjects prior to their bullying involvement.” says Copeland. “This really gives us an idea of the changes bullying brings about.”

Although CRP levels naturally rise in everyone during adolescence, levels were highest in children who reported suffering from bullies. Even at the ages of 19 and 21, children who had once been bullied had CRP levels about 1.4 times higher than peers who were neither wrongdoers nor victims. In a cruel twist, the bullies had the lowest levels of all, suggesting they didn’t suffer the same health risks. They may even see a benefit from their behavior, though Copeland stresses it doesn’t defend their actions. “The goal would instead be to find other ways to produce this protective effect without it being at someone else’s expense.” he says.

Andrea Danese at King’s College London has before shown that ill-treatment during childhood can lead to high levels of inflammation in adult life. “This new study is a helpful addition in showing that these effects extend to another important childhood stressor.” he says. He suggests that care workers monitor levels of CRP in children having psychotherapy to see if it is helping to reduce the stress of being bullied.

1.What do you know about CRP?

A. It relates directly to diabetes.

B. It is a sign of the inflammation.

C. It is a sign of cardiovascular disease.

D. It is a sign of physiological effects caused by bullying.

2.What does the phrase “prior to” in Para.2 mean?

A. through　　 B. during　　 C. after　　 D. before

3.What can be learned from paragraph 3?

A. CRP levels naturally rise along with the increase of age.

B. The bullies are not to blame for the health risks of the bullied.

C. The levels of CRP of the children once bullied are higher than their peers.

D. Copeland intends to defend the benefit of the bullies’ actions.

4. What does Andrea Danese think about childhood ill-treatment?

A. Copeland’s study shows nothing related to it.

B. It doesn’t have much to do with inflammation in adult life.

C. The stress of being bullied is reduced through psychotherapy.

D. Psychological treatment might help solve the problem caused by ill-treatment.

5.What is the main idea of this passage?

A. Bullying is beneficial to the bullies.

B. CRP levels reflect the risks of poorer health.

C. Bullying has lasting harmful effects on a person.

D. Bullying leads to high CRP levels.
