Have you tried public bicycles? Public bicycles have recently become popular in big cities. But some people still question whether it really is easy to use the public bicycles. 1.

A group of students, at Shenzhen High School, Guangdong, are interested in it. 2. Through interviews and an online questionnaire (问卷), they found the

biggest problem was that many bicycles were broken. 3. So, these students designed a smart storeroom that could store and protect bicycles.

They tried many designs, but finally made the smart circle storeroom. A storeroom can store 15 bicycles. Lei Mingcong, 12, the main designer, said he got the idea from his own life. “I found out that our public library has a smart storage machine. 4. Also, I noticed collective clothes

hangers (集合式晾衣架) are often found. They hang the most clothes.”

So how does the storeroom work? There is a smart mechanical device (机械装置) at the center of it. 5. “It is all controlled by computer programs. Just like a‘smart home’, the device

could work by pressing a button ( 按 动 按 钮 ),” said Wang Shunzhi, another designer of the storeroom.

A. It can catch the bicycles and hang them up.

B. It was the rain and sun that caused the problem.

C. It helps readers return books easily and quickly.

D. People also wonder what other problems there are.

E. They did a survey to find out the answers in August.

Some birthday customs(习俗) are quite similar(相似) in many parts of the world---- birthday candles, birthday games, and birthday cakes. But some customs are more specific(特殊的) to certain countries. Here are some children talking about their customs.

Linda---I am fourteen. I come from Aruba. In our country, Children take something special to school for their classmates and all teachers. Each teacher gives the birthday child a small gift like a pencil, an eraser or a postcard. The birthday child can wear special clothes instead of the school uniform.

Lucy---I am one year older than Linda. Denmark is my country. A flag(旗子) is flying outside a window to show that someone who lives in that house is having a birthday. Parents put presents around the child's bed while they are sleeping so they will see them at once when they wake up.

Tom---I am as old as Linda. I am from Brazil. The birthday child gets a pull on the earlobe(耳垂) for each year in my country. The birthday person also gives the first piece of cake to his/her most special friend or relative, usually mom or dad.
