Antarctica is the southernmost place on Earth, and it is larger than the United Sates and 95% of it is covered with ice. The ice is 5 kilometers thick at places and it never melts. At least that is what we thought, but let us keep it that way for now.
The ice seems to be alive as it works its way towards the seA． It forms an ice shelf over the water. The edge breaks away from the shelf and falls into the seA． From here it drifts. Now big pieces of ice become icebergs that can be 160 km long. They now drift north until they finally melt and become part of the ocean. This process is part of a bigger process which in turn forms a cooling system for Earth. This is so important that no country is allowed to control this areA． The treaty (agreement) signed by 12 countries at first and later joined by more, was to prevent any country harming the planet with irresponsible behavior.
The treaty basically states that:
Antarctica can be used for peaceful purposes only.
No country may build a military base there.
No country may do a nuclear test there.
No country may dump nuclear waste there.
Scientists working there will share their information.
Some other rules are there to protect the penguins and seals.
No dogs may run loose.
No planes may land near large groups of animals.
No guns, explosives, or tractors may be used near the animals.
Most important is that every member can inspect any of the other bases if he suspects that the treaty rules are being broken.
While the treaty is not foolproof（万无一失的）, it does play a very important part in the protection of AntarcticA． The more people realize the effects that pollution has on this continent, the bigger the pressure will be on Governments to change the way they look at pollution.

Rules of safety are made to keep people from getting hurt. It is important for everyone to learn how to live safely while at home, work, or play. You should always remember this. Put safety first.
Safety can be practiced at home by following some simple rules. Use ladders instead of stepping up on tables and chairs. Keep stairs well lighted and clear of things for someone to trip over. Fasten down loose rugs. Turn handles of pots inward from the edges of stoves. Keep matches and medicines out of the reach of small children.Keep electric wiring in good repair.
Safety at work has been getting attention from groups of people for many years. Safer machines have been built to cut down on accidents. Red lights warn when equipment is out of order and is not to be used. The proper shoes, gloves, robes, hats, or coats help protect workers on the job.
Safety at play is important, too. Children should use swings and slides properly. Common sense by people boating and swimming will also help everyone around stay safe. Good manners and care for others are part of safety.

A quarrel at home may result in you falling ill. Don’t laugh, it’s true. Family matters including living habits and even the way we speak have a big effect on our health, doctors say.
Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted (晕倒) in class when she heard her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a coma. It is because she is suffering from depression (抑郁症), caused by bad relations at home, doctors explained.
“We don’t get sick or stay well by ourselves,” says Dr Robert Ferrer from the US. Ferrer shows that family forces may explain up to a quarter of health problems, in his recent research.
The genes you get from your family may cause illness. If one of your parents has a heart attack, your risk of being affected may double. But effects on health are not only written in our DNA.
Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment affect our health, too.
Ferrer’s research also found that if teenagers feel they are ignored or unimportant at home they are more likely to get sick.
We may never fully understand all the effects that families have on our health. But just as individual (个别的) problems can have effects on others, a small improvement can have big benefits, Ferrer said.Which of the following can best explain why Wang Xiaoyu fainted in class?
| A．Because her classmates often quarreled in class. |
| B．Because her parents used to quarrel. |
| C．Because of her depression caused by bad family relations. |
| D．Because her classmates shouted loudly at her. |
According to Dr Ferrer, which of the following statements is TRUE?
| A．We get sick or stay well by ourselves. |
| B．Only the genes we get from our family have a big effect on our health. |
| C．Our health has nothing to do with diet, lifestyle and environment. |
| D．Teenagers who are ignored at home get sick more easily than those who are not. |
The underlined word “coma” in Paragraph2 probably means ________.
| A．embarrassment | B．faint | C．tiredness | D．sadness |
The best title for this passage is ________.
| A． Family relations. | B．The reasons why we get sick. |
| C． Happy family makes you healthy. | D．A research about teenagers’ health. |
Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, cannot teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to memorize (记住) some facts or a formula (公式). It is usually quite easy to learn a certain fact in history or a formula in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn’t get everything from school. But they were all so successful. They invented so many things for mankind. Above all, they knew how to use their brains. Whether he is more ________or less, a teacher can’t teach his students everything they want to know.
| A．important | B．useful | C．difficulty | D．knowledgeable (有知识的) |
A teacher’s job is mainly to train his students to master the ability of __________.
| A．learning by themselves | B．making a living |
| C．reading and thinking | D．studying all the subjects |
The reason for scientists’ success is that _______.
| A．they read books that were not taught at school | B．they worked all their lives |
| C．they wasted not a single moment | D．they knew how to use their brains |
Tired of telling students to ask questions and to think about what they were doing, Damien Hynes, a high school geography teacher in Australia, decided to do an experiment to test what he had long been thinking．He wrote some well-organized nonsense （something untrue） on the blackboard．The students simply copied it but very few asked any questions．This shows that students are willing to believe anything given by teachers．The story is repeated in support of the Project for Enhancing Effective Learning （PEEL）．
PEEL was carried out by some teachers and researchers in Melbourne who had concluded that normal teaching methods seldom achieve their intended goals; what the teachers think they are teaching is one thing and what the students actually learn is something else．Students’ lack of an over-all view of learning goals and their concentration on test scores make them see each lesson as a separate activity．
Researchers realized that many students do not come into class empty-headed but have their own explanations of how the world works．Their own ideas can remain important to them even when they differ from scientific explanations that are learned later．In fact such ideas are hardly affected by traditional teaching．Students accept the teacher’s scientific explanation, but do not drop their own．They simply keep both and use them practically: in a class test, they copy the teacher’s idea, but in real life they use their own．
Clearly what was needed was to make students understand their learning process（过程）, and this is what the PEEL teachers set out to deal with．On the surface,（表面） a class being taught by PEEL methods only differs from an ordinary class in being a little noisier, because more people are talking．But there are some meaningful changes．Students are given much more time to express their views, and teachers don’t make immediate judgment．The students are allowed to guide what is done in class and their own ideas are always respected．This draws their attention to the actual learning process, and they become responsible for their own progress．The aim of Hynes’ experiment was to ______．
| A．show that students didn’t think about what they learnt |
| B．prove the effectiveness of the project known as PEEL |
| C．test students’ general knowledge about geography |
| D．encourage students to ask more questions in class |
Why did some teachers and researchers carry out PEEL?
| A．To ensure teachers do scientific work． |
| B．To help students get higher test scores． |
| C．To find the differences between what is taught and learnt． |
| D．To help normal teaching methods achieve their goals． |
An important difference between PEEL and non-PEEL classes is that in the PEEL classes ______．
| A．the teacher does not give the usual scientific explanations |
| B．students always have their own knowledge of the subject |
| C．more attention is paid to the students’ own ideas |
| D．the best explanations are given by the students |
