The common cold is the world’s most widespread illness. People believe that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold, and it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.
In the Second World Was prisoners at the notorious Auschwitz concentration camp, naked and starving, were astonished to find that they seldom had colds.
At the Common Cold Research Unit England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be dipped with cold water, and them stood about dripping wet in wind. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
In the cold we have nothing to do with catching colds. Why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and painkillers such as aspirin, but all they do is to relieve the symptoms(症状).

Many gardeners believe that “talking” to their plants helps them grow---it turns out that they may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language.
For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase(虫荧光素酶), which is what makes fireflies(萤火虫) glow in the dark.
When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out “methyl jasmonate(茉莉酸甲酯)”.
While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators(捕食者) like caterpillars(毛虫) away.
What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other.
However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot!What’s the best title of the passage?

Why are so many people afraid to fail? Quite simply because we forget that failure is part of the human life and that every person has the right to fail. Every person is able to fight failure and finally succeed.
Most parents work hard at preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards(标准). When a child finishes making a table, the mother describes it as “perfect” even though it doesn’t stand still. Another way is to blame others. If John fails in science, his teacher is unfair or stupid.
There’s a problem with the two ways. It makes a child unprepared for life in the real world. Young children need to learn that no one can be best at everything, no one can win all the time, and that it’s possible to enjoy a game even when you don’t win. A child often feels terrible, of course, when he is not invited to a birthday party, or is not chosen into a football team. But parents should not say “It doesn’t matter.” quickly. The young should be allowed to experience failure and be helped to come out of it.
Failure never gives people pleasure. It hurts both adults and children. But it can be really good to your life when you learn to use it. You must learn to ask “Why did I fail?” Don’t blame anyone else. Ask yourself what you did wrong and how you can improve. If someone else can help, don’t be shy about asking them. Success just repeats what has been done. It is not as good a teacher as failure. You can learn how to give a good party from an unsuccessful one. How do most parents prevent their children from failure?
| A． They give them some presents. |
| B． They don’t tell them that they have failed. |
| C． They don’t blame others. |
| D． They help them to come out of failure. |
Which of the following does a person need to learn when he fails?
| A． It’s impossible to enjoy a game if he misses it. |
| B． He is the worst of all. |
| C． It’s natural not to win a game and no one can win all the time. |
| D． His teammates are not good enough. |
Which would be the best title for the passage?
| A． Learning from Failure |
| B． Ways of Preventing Failure |
| C． Reasons of Failure |
| D． Getting Pleasure from Failure |
Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.
Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.
In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.
Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.
Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I’m dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”
The great 19thcentury explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”Which of the following will Kristina Wegscheider agree with?
| A． Traveling alone is a necessary experience for everyone. |
| B． It is more meaningful to travel in foreign countries. |
| C． It is comfortable to travel around without a friend. |
| D． Traveling abroad helps people to find new things. |
Traveling alone is challenging because ________.
| A． you have to make things on your own |
| B． it is hard for you to prove yourself to others |
| C． you can only depend on yourself whatever happens |

What can we infer about Chris Richardson?
| A． He started traveling alone at an early age. |
| B． He was once shot in the arm. |
| C． He used to work as a salesman. |
| D． His website inspires others a lot. |
What is the best title for the passage?

It’s so difficult to follow the ups and downs of a 2-year-old. One moment he’s beaming and friendly; the next he’s sullen（愠怒的）and weepy, often for no apparent reason. These mood swings, however, are just part of growing up. They are signs of the emotional changes taking place as your child struggles to take control of actions, impulses, feelings and his body.
At this age, your child wants to explore the world and seek adventure. As a result, he’ll spend most of his time testing limits, his own, yours and his environments. Unfortunately, he still lacks many of the skills required for the safe accomplishment of everything he needs to do, and he often will need you to protect him.
When he oversteps a limit and is pulled back, he often reacts with anger and frustration, possibly with a temper tantrum (发脾气). He may even strike back by hitting, biting and kicking. At this age, he doesn’t have much control over his emotional impulse (冲动). So his anger and frustration tend to erupt suddenly in the form of crying, hitting or screaming. It’s his only way of dealing with the difficult realities of life. He may even act out in ways that unintentionally harm himself or others. It’s all part of being 2.
It’s not uncommon for toddlers to be angels when you’re not around, because they don’t trust people enough to test their limits. But with you, your toddler will be willing to try things that may be dangerous or difficult, because he knows you’ll rescue him if he gets into trouble.
Whatever protest pattern he has developed around the end of his first year will probably persist for some time. For instance, when you’re about to leave him with a sitter, he may become angry and throw a tantrum in anticipation (预想) of the separation. Or he may cry and cling to you. Or he could simply become subdued and silent. Whatever his behavior, try not to overreact by scolding or punishing him. The best tactic(策略) is to reassure him before you leave that you will be back and, when you return, to praise him for being so patient while you are gone. Take comfort in the fact that separations should be much easier by the time he’s 3 years old.The “ups and downs” (Para. 1) of a 2-year-old refers to ________.
