What are in their schoolbags？

    In America, the school day usually starts at 9 a.m. and finishes at about 4 p.m. The school subjects are different from1. In China, we always2Chinese, math, English, P.E. and so on. But in America, students have more3, such as cooking and driving lessons. Their school life isn't just4study. They also have more things to do than（比）Chinese students. There are many clubs（俱乐部） in American schools, 5. If the students are interested in sports, they6join different sports clubs. American students also have art clubs, language clubs and some7clubs. From 2:30 p.m. to 4 p.m., they do8things in these clubs.

    Maybe you think English is very popular in the world, so American students don't need to 9any other language.10that's not true. American children from the age of seven have to learn a foreign language. For example, they learn French or Chinese.

Few parents can hear the words "What can I do to help?" from their kids. Teenagers spend more time on video games, computers and mobile phones, so they help less with housework.

Students at a primary school in Fuzhou, East China's Fujian Province were required to clean the school toilets to help them develop good habits. But some parents are strongly against the idea. They can't see the advantages of students doing such chores. They think that the school should provide students with a proper education, not the chance to be school cleaners.

In fact, parents, schools and society play an equally (同等地) important role in developing the character of students. It is good for schools to give students such tasks, because few of the students will do them at home. Their parents want them to do homework only.

In recent years, some parents will make mountains out of molehills when students are asked to do some chores in schools. Some will complain the teachers if their kids get hurt in schools; some will even challenge the schools' teaching methods and management. As a result, many primary schools, especially those in big cities, do not let students join in outdoor activities during breaks, fearing that they might get hurt. This is bad for the development of students' best qualities.

What the primary school in Fuzhou doing is worth praising. Doing chores can put a sense of responsibility (责任感) into students' minds and teach them the spirit of rules as well as teamwork. Also, it can make students' in-school experiences more meaningful.

There are many colors in nature. But do you think that a color has weight? Let's do a test.

First, put two objects with the {#blank#}1{#/blank#} weight into two boxes. Then cover the boxes. Third, wrap (包裹) one box with a red piece of paper, the other with white. Now hold the boxes {#blank#}2{#/blank#} your hand one by one. Which one is {#blank#}3{#/blank#} ? It is certain that you will think the red one is heavier. Why do you think so? A scientist did many {#blank#}4{#/blank#} and found that different colors have different weights in a man's mind.

Also, scientists say that people accept the colors they like, and {#blank#}5{#/blank#} the colors they hate. So your body and mind will be {#blank#}6{#/blank#} by using the colors you like. Or you'll be nervous {#blank#}7{#/blank#} even get ill. For example, you {#blank#}8{#/blank#} blue and hate red. If you stay in a room with red windows and wallpaper for two hours, you'll feel you have been there for {#blank#}9{#/blank#} hours. But if the room is blue, you'll feel you have been there for only an hour, And, if a person walks {#blank#}10{#/blank#} of a blue room and into a red room, his temperature will rise. That means our body temperature will change with different colors.

Every year, wildfires destroy millions of hectares of forest land. Homes are damaged, and thousands of people die. Smokejumpers help to stop this. 

Smokejumpers are a special type of firefighter. They jump from planes or are lowered by helicopters into areas that are 1 to reach by car or on foot, such as the middle of a mountain forest. They race to put out fires as fast as they can. 

At a fire site, smokejumpers first examine the land and decide 2 to fight the fire. Their main goal is to stop a fire from spreading or to slow its progress  3 ground—based firefighters arrive. Using basic equipment such as shovels (铲子) and axes(斧头), smokejumpers clear land of burnable material, like dry grass and dead trees. They carry water with them, too, but only a limited amount. 

Most smokejumpers are men. The most important factors are your height and  4 .Smokejumpers employed in the United States must be between 54 and 91 kilograms so they don't get blown away by the strong winds or get 5 when they land. 

The work is dangerous, and the hours are long. But for these firefighters, smoke jumping isn't just a job. They6 being able to jump out of planes, fight fires, and live in the forest. As 28-year-old Russian smokejumper Alexi says, "This is the best job for tough guys. "
