The Olympic Games are the {#blank#}1{#/blank#}(big) sports meeting in the world. There are two kinds of Olympic Games. One is the Summer Olympic Games, and the other is the Winter Olympic Games. {#blank#}2{#/blank#}of them are held every four years on a regular {#blank#}3{#/blank#}(base). All countries can take part if their athletes have reached the {#blank#}4{#/blank#}(agree) standard to the games. In the past women were not allowed to take part in the Olympic Games. Nowadays, women have a chance {#blank#}5{#/blank#}(play) an important role in the great games. Because of so many athletes, a special village is needed to build for {#blank#}6{#/blank#} to live in, {#blank#}7{#/blank#}(include) a main reception building, several stadiums for competitions, a large swimming pool, and seats for audience {#blank#}8{#/blank#}watch the games. It is a great honor to host the Olympic Games. In addition, for many countries it's just as much competition to host the Olympic Games {#blank#}9{#/blank#} to win Olympic medals. Nowadays, the olive wreath has been replaced by medals. But it's still about being able to run {#blank#}10{#/blank#}(fast), jump higher and throw farther.

    John Carter was rescued from the sea near his holiday home yesterday. The accident happened while he{#blank#}1{#/blank#}(walk) along a steep cliff at the edge of the sea. He was blown off by a strong wind and{#blank#}2{#/blank#}(fall) into the sea, 30 meters below. Luckily, a woman saw him in the sea soon afterwards and she called the police rescue service. Mr. Carter was taken to hospital with a{#blank#}3{#/blank#}(break) arm. "I'm very lucky to be alive," he said. "I can't thank the woman enough."

    In the age of the smart phone, there seems no reason to ask questions about: the weather forecast, a business's phone number or directions, {#blank#}1{#/blank#} can be easily found on Google, but very often people {#blank#}2{#/blank#}(actual) ask these things by {#blank#}3{#/blank#}(make) a phone call. Your answer may be replied to with a thank­you e­mail. This isn't the first time that great changes {#blank#}4{#/blank#}(take) place in our manners due to technology. In {#blank#}5{#/blank#} late 1870s, when the telephone {#blank#}6{#/blank#}(invent), people didn't know how {#blank#}7{#/blank#}(greet) a caller. Often there is just {#blank#}8{#/blank#}(silent). Alexander Graham Bell, the inventor, suggested that people say "Ahoy", {#blank#}9{#/blank#} finally "Hello" went out. The greeting is now used in everyday face­to­face communications. Try to be respectful no matter who you communicate {#blank#}10{#/blank#}. Just keep it in mind that politeness never goes out of fashion.

    You may not have noticed it before, but many people often sit with a hunched (驼背的) back when they are in a difficult situation, such as trying hard {#blank#}1{#/blank#} (solve) a math problem. But there's a reason for this: this body position helps to reduce pressure.

     However, according to Erik Peper, a health professor at San Francisco State University, poor posture (姿势) may make our brains work not as well as they {#blank#}2{#/blank#} (normal) do.

    Peper and a team of researchers {#blank#}3{#/blank#} (study) 125 students' performance in a math test and their different postures. The team found that good posture—for example sitting up straight—could help people perform better {#blank#}4{#/blank#} bad posture when they feel stressed.

    Another professor Richard Harvey further explained in Science Daily that sitting with bad posture might make us feel more {#blank#}5{#/blank#} (comfort), but it actually increases our pressure levels.

    So the next time you have to take a test, try sitting upright and taking a deep {#blank#}6{#/blank#} (breathe). If Peper's study is correct, this small change may have {#blank#}7{#/blank#} great influence on you.

    There are many things {#blank#}8{#/blank#} lead to poor posture. The good news {#blank#}9{#/blank#} (be) that posture can be improved at any age by {#blank#}10{#/blank#} (make) just a few simple corrections in the way one stands, sits and moves.

    The silent killer — air pollution causes seven million premature (过早的) {#blank#}1{#/blank#}(death) a year, not just in{#blank#}2{#/blank#}(develop) countries but also in UK and the USA as well. In China，people are well aware of the health problems it brings.

I check every part every day. If it has heavy air pollution, I will prepare masks for my family. I dislike{#blank#}3{#/blank#}when the air is bad. Because bad air makes it difficult for me to breathe and I think it does influence my{#blank#}4{#/blank#}(perform) at work. A new research in china has also found a link between air quality and levels of intelligence. In the study, 25,000 people living across China{#blank#}5{#/blank#}(test) in language and math skills last year. They found the results of those{#blank#}6{#/blank#}lived in more polluted areas were{#blank#}7{#/blank#} (negative) impacted, especially in languages. It adds to a growing body of evidence that air pollution has an effect not just on the lungs and heart{#blank#}8{#/blank#}on the brain.

    This research shows that the longer we are exposed to air pollution, the {#blank#}9{#/blank#} (many) problems we're storing up for later life. Campaigners hope this study will persuade the British government{#blank#}10{#/blank#}(think) hard before it publishes its clean air strategy next year.
