Do you know the way of using wind power to make electricity? There are many advantages({优点) of using wind to make electricity. Here're some of them.

    First, it may be one of the cheapest ways to make electricity. Second, it can make and store hydrogen gas. The most important one is that it won't pollute the environment. Besides, the wind power can be reusable.

    But large wind farms might kill birds too, because birds always fly into the wind turbine(风力涡轮机). Scientists are looking for ways to stop it.

    Experts said that by the middle of the 21st century, wind power could supply more than 10% of the world's electricity. Wind really helps us a lot.

    Humans have learnt many things from nature. These things have helped us in our daily life. The latest thing is self-repairing clothing.

    Scientists have developed a special way for clothing to repair rips and tears by itself, without the need for sewing. It works with materials such as cotton, linen and wool. The scientists are from the Naval Research Office and Pennsylvania State University in the USA. Scientists Dr Walter Dressick and Dr Melik Demirel looked at how a squid can cling on to things so well. The research team found a protein in the rings of teeth that cover the suckers on a squid. The protein is similar to the one found in the silk that spiders use to make spider webs. It is very strong and elastic.

    The new protein has been developed as part of a coating, which is put on clothes. When the coating is dipped in water, the area around the rip or tear joins together in less than a minute. This could help clothes last longer and save money for us. It could also be useful for military and survival clothes. People like soldiers and mountaineers would be safer if they had clothes that could be repaired quickly and easily. Professor Demirel spoke about the invention. He said," The coatings are thin, less than a micron, so they wouldn't be noticed in everyday wear." Then he added, "Even thin, they increase the overall strength of the material. For the first time, we are making self-healing textiles."

In the warm waters near an island, a small group of dolphins comes up for air. The dolphin in the front is Mother Dolphin.

Mother Dolphin will 1 Baby Dolphins for a long time. She'll stay beside her babies until they grow up. Baby Dolphins are very playful. They can swim well and love to push their mother softly. After playing so much, they get tired. At night, they 2 just below the surface of the water with Mother Dolphin.

Dolphins may look like fish, 3 they aren't really fish. Dolphins have their own underwater language of sounds. They use these 4 to communicate with each other.

Dolphins always travel in small groups to 5 themselves against their enemies, like the shark. They can live for many years. Some dolphins live up to 35 years in the wild.

Our school will hold an English Week. We can communicate with others about the English learning methods there. What's more, we're sure they will help you learn English more easily and with more fun!

The winter solstice, or dongzhi, is the 22nd of the 24 solar terms(节气) in the Chinese lunar calendar. It usually happens {#blank#}1{#/blank#} December 21st, 22nd or 23rd. People in different parts of China have different customs on this day. 

Eating dumplings, or jiaozi, is a common custom for many Chinese on the winter solstice, {#blank#}2{#/blank#} those living in the north. Why do we eat dumplings on this day?

It is said {#blank#}3{#/blank#} this custom is to remember Zhang Zhongjing, a famous doctor of the Eastern Han Dynasty. He was the {#blank#}4{#/blank#} person to make them. People called this food "Jiao'er" for its shape at that time. During the Three Kingdoms Period(三国时期), dumplings became a popular food. In the Song Dynasty, dumplings{#blank#}5{#/blank#} to Mongolia(蒙古). Influenced by Mongolians, dumplings had {#blank#}6{#/blank#} fillings(馅) . Then Mongolians spread {#blank#}7{#/blank#} to all over the world.

Make a timetable!

 Do you have problems after starting junior high? You may have more subjects to learn and less(更少的) time for sleep. But some classmates adapt(适应) quickly to their new school life. Nick makes a timetable. It shows his daily life from 6:30 am to 10:00 pm. It helps him arrange(安排) his school days well.

 So how can a timetable help students? First, it can help them live a healthy life. Some students have no time for a good breakfast or some exercise. With a timetable, they can do them well. Second,a timetable can help them do more things in one day. It sets(设置) time for differ- ent things, so they know what to do at different times.

 You may find it difficult to keep a timetable. But when you do the same activities every day, they finally become your habit(习惯).
