As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.

    Scientists have found out that the radiation(辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health. The harm of the radiation won't be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far. Space rubbish is also thought to be a great danger to spacemen. It's reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion(爆炸) in space in 1999 made a cloud of 300,000fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage(损坏).

    Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may become possible for people to spend a few days in a space hotel. People may even choose to leave the earth and live in space in a few years. So scientists are doing everything they can to help improve the space environment.

Nowadays more and more people prefer to go fishing or hiking in the woods. Experiencing nature is {#blank#}1{#/blank#}, but when you're doing this, always keep yourself safe. It's important to remember several basic rules if you don't want to turn a pleasant outing into a {#blank#}2{#/blank#}.

First, be fully prepared for different weather. Before you set out, always get warm clothes and raincoats ready, just in case! This is especially true in the {#blank#}3{#/blank#} of travelling in the mountain areas. The weather is really {#blank#}4{#/blank#} in high mountains. Sometimes you can experience two or three seasons in one day.

Second, {#blank#}5{#/blank#} a map, a compass, and a flashlight in your bag. Even experienced travelers get lost. Before you start your trip, study the map to get familiar with the area you are going to. The flashlight is important if you do get lost. Many trips that start out in daylight will {#blank#}6{#/blank#} become nighttime adventures when people can't find their way.

Third, bring a first-aid kit and know how to use it. Small cuts can be more serious when there is no doctor {#blank#}7{#/blank#}.

Finally, tell people where you are going and when you plan to come back. That way, someone will go search for you if troubles {#blank#}8{#/blank#}. This will increase your chance of being found quickly.

Is there anything in your community that could be changed? Is there a person in your neighborhood who could offer help? If you're hoping for someone to make a difference, that someone could be you! {#blank#}1{#/blank#}. And you'll feel good about doing something that helps people or improves the places around you. 

Last summer, my friends and I noticed how messy our neighborhood park was. We wanted it to be different. {#blank#}2{#/blank#} . We had a great time making the park even better than before, and now the whole neighborhood is able to share and enjoy it again. 

Maybe cleaning up a park isn't your choice, though. No problem! {#blank#}3{#/blank#}. Do you like playing chess, reading or spending time with your pet? You can volunteer to do what you love. For example, you could help at an old people's center, simply by talking or playing games with them to make their days better. {#blank#}4{#/blank#}, you could volunteer to be a homework helper at your school. You're always needed to walk dogs or play with cats. Or you can collect things for homeless people, such as soap and toothbrushes. 

You see, there is something for everyone. Whatever you do as a volunteer, your time will be enjoyed and that always feels good. {#blank#}5{#/blank#}. You can, too!

A. If you're great at math or English

B. Volunteering your time is a great way to make a difference in your community

C. Kids everywhere are making a difference by volunteering

D. You can turn anything that matters to you into a volunteer project

E. We worked with our parents and teachers to clean up the park

Hello, everyone!

……

This is a nice room. I like my room very much.

The Arctic Region（北极地区）is one of the coldest place in the world. It is cold all the year round. Spring comes from May to June. The ice and1 begin to melt. The plants begin to grow and the animals look for2 . The summer comes from July to August. The temperature in summer can get only -8℃. It should be the warmest3 here. Autumn comes from September to October and it lasts4 .5 comes quickly from November to April next year. Winter is the6 and coldest season of a year. And the Arctic Region is filled with ice and snow everywhere. At this time there is no7 . So it looks like night in winter.

Are there any people living in such a8 place? Yes, they are Eskimos. It is9 for them to live there, but they live happily with a long10 .

"The best mianshilies in China and the best Chinese mianshilies in Shanxi." Can you imagine that in North China's Shanxi Province, there are over 280 kinds of mianshi, or cooked wheaten (小麦的) food?

Shanxi people's love for mianshiis closely connected to the local natural conditions. The dry weather on mountains and plateaus (高原) makes it a good place for growing wheat. Therefore, as time passing by, Shanxi people not only developed an eating habit for mianshi, but also invented different ways of cooking wheaten food.

Among the many Shanxi mianshi, the sliced (削的) noodle is the most famous one. It is a noodle made with a special knife. When making it, the cook needs to hold the dough (生面团) with one hand, while fast slicing the noodles into the soup pot with the other hand. The length and thickness of each sliced noodle are required to be the same. Experienced cooks can even turn the way of slicing noodle into an excellent show. They can slice 200 noodles in one minute, and make sure each noodle falls exactly into the soup pot 1.5 meters away.

In Chinese food culture, people like to give special meanings to the food. For example, they would have a bowl of Changshoumianon their birthdays, carrying good wishes for health and long life. In many places, the tradition is to serve jiaozito a person leaving home, and noodles to a person returning home, as both foods have their own important meanings.

Well, seeing all these Chinese mianshi, do you feel enjoyable? Would you like to have a try?
