Americans love to drive on their holidays. Usually, the family gets into a car or recreational vehicle(RV，旅行房车) and drives for a summertime trip across the country.

    RVs are like our houses. There are kitchens, bathrooms and bedrooms in RVs. They are big, but can be very small when you share a bed with your little brother or try to play a game.

    But RV travel is a great time with the family. You can see the country in your own "home". You can spend every night in a different place. And, you don't have to pay for hotels or restaurants, only gas(汽油). Best of all, you are free to go everywhere you want at any time.

    In 2011, when British photographer David J. Slater was visiting a park in Indonesia, his camera was taken away by a group of black monkeys. The result was hundreds of monkey selfies(自拍照). The best ones show a monkey smiling toothily for the camera. {#blank#}1{#/blank#}

    Nobody knew they would create a copyright (版权) battle three years later.

    Last month, a website put the monkey selfies online under a collection d free photos without Slater's permission (允许). {#blank#}2{#/blank#}

    However, the website refused to do so. They said that according to US copyright law, whoever pushes the button on the camera owns the copyright to the photo. {#blank#}3{#/blank#}

    They said, "US copyright law says that works that come from a non-human source can't ask for copyright. That means monkeys don't own copyright. "

    {#blank#}4{#/blank#} He said he bought the cameras; he spent a lot of money traveling to Indonesia, and it was his carelessness that allowed the monkeys to take his cameras away.  All these have made him own the pictures, no matter who pushed the button. In a sense, the monkeys helped him take the photos, Slater said.

    {#blank#}5{#/blank#} Who do you think will win this interesting battle?

A. It was the monkeys but not Slater that pushed the button.

B. As of now, there has been no result in the Monkey Selfie case.

C. Slater then sold the photos and they became popular on the Internet.

D. Slater asked the website to take them down since he owns the copyright.

E. Slater argues that the pictures belong to him as they were taken from his camera.

    Stanford is a world famous university on the west coast of the US. {#blank#}1{#/blank#}, because the poor boy died of a strange disease.

    Tourists are often surprised at the beauty of Stanford. Among the green trees, buildings with yellow walls and red tops make up a beautiful picture. {#blank#}2{#/blank#}. That's because they were the favorites of Mrs. Stanford.

    {#blank#}3{#/blank#}. It stands at the center. It was built by Mrs. Stanford to remember her husband who devoted himself to the university. There, students and teachers can communicate with God, and they can also hold great activities, such as concerts and celebrations.

    {#blank#}4{#/blank#}. It is the landmark of the university. A man named Hoover had done a lot for the university. The things he once used can be seen on the first floor. On the top of the tower, tourists can have a good look at the whole campus.

    As one of the world top universities, Stanford has many subjects that stand among the top ones in the world. {#blank#}5{#/blank#}. If you want to study computer in a university abroad, maybe it is your best choice.

    Body language is used by people for sending messages to one another. It is very useful because it can help you make yourself easily understood. When you are talking with others, you are not just using words, but also using body languages. {#blank#}1{#/blank#} A smile and handshake show welcome, and clapping hands means congratulations. These are accepted both by Chinese and foreigners as having the same meanings.

    {#blank#}2{#/blank#} For example, men in Russia, France and Arab countries kiss each other when they meet, but men in China or Australia shake hands instead of kissing. People in Puerto Rio like touching each other, but people from English speaking countries do not touch each other. {#blank#}3{#/blank#} In some Asian countries, you must not touch the head of another person. People in Arab countries like standing close to one another when they are talking. {#blank#}4{#/blank#} In Arab countries, you eat with the fingers of your right land; the left hand is not used at all. In parts of Asia you must not sit with your feet pointing at another person.

    When you use a foreign language, it is very important to know the meanings of body languages in the foreign country. Following this will help you live and work better with foreign people.

    There has been a lot of talk about Chinese bicycle sharing recently. Shared bikes are nowadays becoming the centre of attention in our We Chat friend circle. Many of our friends post photos of themselves riding bikes, especially during the weekend in natural parks, and we can see people logging in and out of shared bike apps. But are people really drawn to(被....所吸引) the idea of exercise and green transportation all of a sudden?

    Some people have tried Mobikes lately, and they don't particularly like Mobikes. They think the first generation Mobikes, the ones without baskets, are designed for athletes. They are very hard to ride, and the seat is not adjustable(可调节的). Then, they tried the yellow ofo bikes. They are easier to ride than Mobikes, but they don't usually have baskets, and you need to enter the password by hand, instead of scanning a QR code and having the lock open automatically like with Mobikes.

    We appreciate that there are shared bikes on the roads. They have saved us a lot of time during emergency situations. And on beautiful, clear days, we do enjoy riding them outside the city. But from what we've seen in our friend circles, people have been giving them endless praises, while we still saw some obvious flaws (缺陷).

    In our experience, there has never been a unanimous(一致的) decision on anything in public opinion. It makes us wonder whether these people really like riding shared bikes or are just saying this to agree with others. When we asked them individually, a friend of us, Lisa, secretly told us she tried the bikes to fit in(融入朋友圈). She doesn't like bikes and finds city's roads too harsh for bike riding. But the only way to hang out with her friends was riding out of town together. To join in social activities, she had to pick up bike riding again. Another young man, Simon admitted that he started talking about and forwarding information(转发信息) on shared bikes to appear cool and fashionable to friends. He started paying attention when Mobikes firs launched(推出). These views will give us something new to think about when we ride these bikes again.
