Clothes are traditionally made of natural materials, such as cotton, leather and wool. They are all from plants or animals, but that doesn't mean they're friendly to the earth. For example, farmers have to use a lot of chemicals to grow cotton plants.

    Scientists are now looking for new ways to make clothing materials. They hope the new materials are both comfortable and good for the earth. Scientists have worked out how to make materials out of cornhusks (谷壳), chicken feathers and rice straws.

    "They used to be useless things. We always have a problem of how to deal with them," Yang, a scientist says. "Now, we can turn them into beautiful materials. Chicken feathers are better than other things. They have small air pockets like honeycombs. That means it will be very warm if you use them to make a jacket or sweater, and I think more and more people will like to buy these kinds of clothes."

    There are many online food shopping sites. Things l{#blank#}1{#/blank#}CDs, books, and DVDs sell well online. But it is quite different to sell food online because people like to see food with their o{#blank#}2{#/blank#} eyes. It is very I {#blank#}3{#/blank#} for people to buy fresh fruit and vegetables. Customers like to c{#blank#}4{#/blank#} their food by its color. They also want to touch and smell it. Some people like going to the same shop to buy food with good quality. So if the food is always g{#blank#}5{#/blank#}, they will feel comfortable buying it online.

    Boxes of fruits and vegetables have been d{#blank#}6{#/blank#} to homes around Britain for a few years now. Dried or canned foods are almost the same all the time, but fresh things are not. For example, People may want to pick their own apples so they can take the o{#blank#}7{#/blank#} that look nice. Buying dried and canned food online is easier. A person can buy this kind of food on the Internet and then buy fruits and vegetables at a store or a market.

Last Saturday, Tony went to see Benny. But he didn't know1Benny lived.2the way, he stopped in front of a yellow house, and asked an old woman the3to Benny's house. "His house is not far from my house," said the woman.

"It's behind the trees. But you can't get there4. You can go there by bus. It'll5you hours to get there6foot."

"What's7with her?" Tony thought." "I can see Benny's house from here now. It's behind the8."

Then Tony walked to the other side of the trees. He found the old woman was9.There was a river in front of him, and he couldn't see a boat. The house was on the other side of the10.

The Spring Festival(春节)is coming.You will buy new clothes and much food.There are always some old clothes you don't want.And there is always some food you can't eat.What can you do?Take them to two places(地方)，

Take a look at the following ads! You may find some useful information you need here!

My name is Leo. These days, I have online(线上的) classes. I have a lot to share about them.

When I take lessons at school, I usually spend much time on the way to school and go back home. But when I take lessons at home, I can sleep more in the morning and it makes me feel full of energy. 

Even though I have classes online, I listen to the classes and take notes carefully. Sometimes, teachers give students several questions in the teaching videos(教学视频) and I always get myself ready for solving these problems. When I can't understand the teachers in class or don't have lessons on time, I can watch the videos again. 

However, it's not always good for me. I sometimes feel upset about online classes. The Internet is slow when too many students use the Internet at the same time. In online classes, I only see my teachers on the computer. And talking to my teachers is like talking to the computer. Also, I can't talk with my classmates at any time. 

At school, I talk with my classmates during the breaks between classes. We often tell each other about our daily lives. But now we stay at our homes and do other activities. Even I try to talk to my classmates online, they may stay in bed or listen to music. 

I think online classes are helpful but I still look forward to having lessons at school and meeting my teachers and friends face to face.
