Chemicals used for industrial processes often create dangerous forms of waste. The amount of these chemicals has risen heavily in the past few years, as more areas of the world industrialize and new products are produced. Over 80,000 different chemicals are used in industries world wide. Around the world hundreds of millions of tons of harmful waste are produced each year. Often, it is difficult and expensive to get rid of these chemicals or to store them in a way that does not endanger human life and the environment.
Every year, major health problems result from harmful waste. Sadly, it is often when someone has died or, become seriously ill that governments will take action and reduce levels of dumped harmful waste. In 1989, a school in New Jersey had to be closed because students there had suffered too much exposure to chromium. It was later learned that large amounts of chromium had been dumped nearby and blown over to the school area.
Research has been done to provide information on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how the combinations of these chemicals affect human health.
Some governments have realized how serious the problem is and are making laws to get rid of harmful waste. They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but the public as well must form part of the solution. They can choose not to buy those products which require the production of harmful waste, attempt to affect policymakers, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one-third using existing technologies and methods.

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 |
| D． it will finally build your character |
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. |

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 ________.
| A．his falling down and standing up |

Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.
An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.
However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.
In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible?
Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents—today’s grandparents—would have called their children more often if the means and cost of doing so had not been a barrier.
Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.
Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.The surveys inform us of______.
| A．the development of technology |
| B．the changes of adult children’s behavior |
| C．the parents’ over-protection of their college children |
