In most parts of the world, many students help their schools make less pollution. They join environment club. In an environment club, people work together to make our environment clean.

    Here are some things students often do.

    No-garbage lunches. How many lunch bags do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classa that make the least garbage and report them to the whole school.

    No-car day. On a no-car day, nobody comes to school in a car including the students and the teachers. Cars give pollution to us, so remember:

    Walk, jump, bike, or run!

    Use your legs! It's lots of fun!

    Turn off the water! Do you know that some toilets can waste twenty to forty cubic（立方米）of water an hour? In a year, that would fill in a small river. In the environment clubs, students mend（修理）those broken toilets.

    We love our environment. Let's work together to make it better.

    Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they have no teeth or claws. But plants can protect themselves in both physical and chemical ways.

    Some plants have their own ways to keep animals away. For example, the leaves of the holly(冬青) have sharp prickles(刺) that discourage grass-eating animals. Holly leaves on lower places have more prickles than leaves on upper places. This is because the lower leaves are easier for most animals to reach. Some plants, such as the oak trees(橡树), have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material, and eating such grasses wears down the animals' teeth. Many plants also have chemical defenses. Some plants produce chemicals that taste bitter(苦) or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a worm bites a tobacco leaf (烟叶), the leaf produces a chemical smell. Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly leaves, and each prickle has poisonous water(毒液). Only one experience with this kind of plant will teach an animal to stay away from it in the future.

    When we talk about the universe, we mean not only the earth, the sun and the moon, but also the stars and space between them. There are millions of stars in our sky. The sun is one of them. Around it there are eight big planets moving, including the earth. The moon is our nearest neighbor in space. If you look at the sky on a clear night, it is possible to see about 3, 000 stars. They look small, but they are really very big hot balls of burning（燃烧着的）gas. Some of them arc huge（巨大的）, but others are much smaller like our planet Earth. The biggest stars are very bright, but they can only live for a short time. Every day new stars are born and old stars die.

    All the stars are very far away. The light from the nearest star（except the sun）takes more than four years to reach the earth.

    Hundreds of years ago, people used stars, like the North Star, to know which direction（方向）to travel in.

Today you can still see that star.

  Why are so many people so afraid to fail ? Quite simply because no one tells us how to face the failure (失败）. In fact, failure can become experience that means growth. We forget that failure is part of the human condition and that every person has the right to fail.

Most parents work hard to prevent failure or protect their children. One way is to lower (降低)standards. Nearly 60% of the parents choose this way. When a child finishes making a table, the mother describes it as "perfect" even though it doesn't stand still. The other way is to blame (责怪）others. If John fails in science, his teacher is unfair or stupid.

There's a problem with the two days. It makes a child unprepared for the real life if they don't meet enough failure. The young need to learn that no one can be the best at everything, no one can win all the time. The young should be allowed to experience failure. 

Failure never gives people pleasure. It hurts both grown—ups and children. But it can be really good to your life when you learn to use it. 

The world's attention turns to Sweden for the announcement (公布) of the Nobel Prize winners 1 December 10 each year. The Nobel Prizes, six prizes given to groups or individuals who are really excellent in 2 fields, were founded by a Swedish inventor, Alfred Nobel. 

 Alfred Nobel was the man who invented dynamite, a 3 explosive(炸药). During his life, Nobel made a lot of money from his invention, and he decided 4 he would use his money to help scientists, artists, and people who worked to help 5 around the world. 6 he died, he decided to place the money in a bank and the interest(利息) would be given out as five cash prizes every year. 

 The prizes 7 were set up by Nobel were first handed out in 1901, including physics, medicine, chemistry, literature, and peace. Later, in 1968 the Bank of Sweden 8 a prize in economics to celebrate the bank's 300th year of business. 

 The person who receives a Nobel Prize 9 a cash prize, a medal, and a certificate. The money for each category is worth about 1. 5 10 dollars. The aim of the prize is 11 the winner to carry on working or researching, and they don't have to worry about 12 money. 

 The prizes can be given to either individuals 13 groups, like Albert Einstein, Tu Youyou and the United Nations. The prize winner who has won the 14 times is the International

Committee of the Red Cross. This organization has received three Nobel Peace Prizes, and the founder, Jean Henri Dunant, was awarded 15 first Nobel Peace Prize in 1901.

It's no secret that there is a space（空间）problem in Manhattan（曼哈顿）.People build up higher and higher buildings because there isn't much land left and there is no room to build out.So people have been building lots of tall and thin buildings.Developers（开发商），the government has made laws（法律）that don't allow developers to build too high buildings.

Oiio Studio thinks about things differently， "what if our buildings were not tall but long？" So the founder of Oiio Studio，loannis Oikonomou（设计）a U﹣shaped building，the Big Bend.It would be a very thin building.It would curve at the top and return to the ground.Oikonomous said he thought of the great idea because he learned from a piece of news.It said that a company made a lift that could travel in curves.So he designed the Big Bend.He thought it as "the longest building in the world".It would be 4000 feet from end to end and would need a different lift system.

"We can't change the law，  ▲   .So if we can bend（使弯曲）our building，" Oiio Studio said.

The Big Bend is just an idea for now.Oikonomous has sent the plans to a few companies，and is looking for developers.If successful，they will build the Big Bend around West 57th Street
