1 . Nowadays, smart phones are becoming more and more popular among middle school students. But schools don’t allow (允许) students to bring their phones to school. Many people discussed about whether the phones are good for students or not. They have different ideas.

Some think it is good for students. They can look for some useful information for their study on the phone. Then the students can use it as a tool (工具) of study. Also, they can call their parents at any time.

But some people do not think so. They think it is bad for students. Because some students can’t use the phone in the right way. They may use mobile phones to play games and waste much time on it. What’s worse, some students become a phone addict, taking the phone anywhere anytime.

In my opinion, smart phones are good for students. As we know, the 21st century (世纪) is full of information. A smart phone is one of the quickest tools for us to exchange information. It is a fashionable and useful invention (发明). It makes our life more colorful. So we should make the best use of it. And it’s not wrong to follow the fashion, but the most important thing is how to use the smart phone properly. If you can use it in a right way, you will know many things out of classroom.

These days schools don’t allow students     1    （bring）mobile phones to schools. Many parents are worried. How can they connect（连接）with their kids? Well, smart watches may be the answer to their worries. Smart watches are like small computers. They usually tell time and count a     2    （person）steps. Most smart watches connect with smart phones and they let the users     3     （make）calls, and send and receive messages. Often smart watches have microphones（麦克风）and speakers. Some even have     4    （camera）.

Many parents buy smart watches     5     their children because they are too young to have a mobile phone. They are     6    （little）worried because they can call their children at any time through smart watches. Also, many smart watches have GPS trackers（追踪器）    7     their children are, so they know if everything is OK.

But now some groups in Europe say many smart watches are not as     8    （safe）as what we think. Some watches allow more than parents to track where the children are. They also allow anyone to send the children a message. People can also control the watches from far away to watch and listen to the children.     9    （be）safe, anytime a smart watch makes a call or sends a message or GPS information—the information should be processed（数据处理）. So no one     10    （别的）can get the information.

3 . If you are joining in chat room conversations, or writing e-mails with net pals（网友）, you are one of the millions who write in a special, short form of English.

Throughout the world, every night children and their elders are “talking” online—many of them are talking at the same time.

It’s fast: trying talking to six people once. It’s easy: three or four words per exchange. It takes cleverness and quick fingers.

And it requires very simple language. There’s neither time nor space for explanations. Why waste valuable time telling six friends you have to leave for a moment to take care of your little brother when BRB（=be right back）will do?

Want to enter a conversation? Just type PMFJI（=pardon me for jumping in）.

Interested in whom you’re talking to? Type A/S/L, the common request（要求）to know your pal’s age, sex（性别）and location（地点）. You may get 15/M/NY as a reply from your pal.

If something makes you laugh, say you’re OTF（=on the floor）, or LOL（=laughing out loud）, or join the two into ROTFL（=rolling on the floor laughing）.

And when it’s time to get back to work or go to bed, you type GTG（=got to go）or TTYL（=talk to you later）.

People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital （大写字母）letters are left in the dust, except when expressing feelings, as it takes more time to hold down the “shift” key and use capitals. Punctuation（标点）is going too.

Cell phones have become one of the most useful devices in the past half century. The first cell phone had only one use—calling someone. Today’s smart-phones are really minicomputers that     1     users to do many things at once. People can send texts and emails, listen to music, take pictures and videos, and find information online.

Cell phones are perfect for learning in school. For example, students can find information on the Internet,     2     math problems and share notes. They can use calendars and alarms for reminders about homework, projects, and tests. They can even share ideas on social media.

Some schools don’t allow cell phones     3     they think the phones can distract(分心) students from their work. Some teachers worry that students won’t pay attention and will need to be reminded to put down their phones. They also worry that students will spend lunches and recess(暂停) playing games or using social media. Kids could miss out on quality time spent with friends.

Teachers and parents also worry about students using phones to cheat on tests or bully others. Cheating is unfair and does not help students learn. Bullying     4     classmates. Studies show that younger students are more likely to be bulled if they have cell phones.

However, researchers have found that most parents and teachers want students to have phones. It is important for parents and children to be able to keep in touch, Teachers like using phones during lessons because students are more interested and pay     5     attention.

Many teachers feel that the benefits outweigh(重于) the problems if students learn to use the cell phones     6    . Teachers and parents can teach kids to use cell phones in a safe way that helps them learn new things. In class, phones should be     7     and used only for lessons. Students should also track time spent on their phones and avoid using them too much. Students should be allowed to use cell phones in school. Setting good ground rules can improve learning for everyone.

In the past, my old grandmother didn’t enjoy talking on the phone. Actually, she hated it so she always refused（拒绝）     1     it. She told us that she preferred speaking to people in person. It always     2     her sad that she couldn’t see the person she was talking to. The other day, we chatted with my grandmother,     3     mentioned video calling over the Internet. It was     4     for people to see each other while talking online. Then we     5     up with an idea. We bought her a laptop（笔记本电脑）. One of my cousins went over to her house and taught her     6     to use it.     7    , she was a quick learner.

Now she enjoys     8     when talking with us every day. She is happy and you can tell from the expression on her face. She says it’s also very     9    . She can put it anywhere in the house because it is small and doesn’t take     10     much room. Sometimes she even talks to us while she’s in the kitchen cooking!

Now you can easily see people phubbing (低头族). Yes, “phubbing” is a newly popular lifestyle among people. We can see the same situation almost everywhere, in the subway, restaurant or on the street. People are watching their cell phones instead of watching their way while walking. Now, we can even look up this word in a dictionary called Australian National Dictionary.

From family dinner table to friend’s parties, people never stop checking their e-mail, WeChat and so on. It’s said that, during the Spring Festival dinner, all the grandchildren were looking at their cell phones instead of saying a word to their grandparents. The old people felt sad. Finally, they got unhappy and left the table. Also, we find that more and more people like taking photos of the food as soon as it’s put on the table. “My skill of taking photos has improved much but my interest in food has dropped a lot.” said Chen Lin. She is a university student from Xi’an. Some people can’t fall asleep without checking his cell phone or iPad.

Let’s put down our cell phones before the problem of “phubbing” gets worse. After all, we have many interesting things to do. We really should spend less time on cell phones and enjoy the daily life.

In the United States, 73 percent of teens have their own smartphones. Some of them use phones in class. 90 percent of teens use phones to chat, play games, listen to music and watch short videos. It costs them too much time and it’s really not a good thing for     1     health and     2    . Unfortunately, kicking the habit of using phones and other mobile devices(设备) for teenagers can be hard.

Smartphones and other devices can be very     3     in class and daily lives. A quick Internet search can turn up more facts. As the saying goes, there’s an app for that. Smartphones make it easy to get information for teens. Some apps can even replace heavy, paper textbooks. And that’s not all. Teachers can send out the test by phone and then it can clearly to show the test results. In general, teachers think these devices could improve learning, but they are also     4     about their students becoming distracted(分心). That is a really serious problem. Students use smartphones too     5    . After school, they want to use their phones to check the answers     6     they do their homework, which leads them not to think dependently. Some students are crazy to games and lost interests in learning. Some students are too fond of playing with mobile phones, and they don’t want to go out to     7     with friends and relatives face to face, and they are not     8     in outdoor sports.

In order to pay more     9     in class or even outside of school, trying to stop your habits. Turn off your phone, or give it to your parents. Move your head     10     from the phone screen, and you will open a colorful and exciting world.

10 . The mobile phone has become a problem for middle schools. Some middle schools in Australia have banned（禁止）students from carrying mobile phones during school hours.

Teachers said mobile phone use is a distraction（分心的事）to students during school hours and it also gives teachers so much trouble in their classrooms. They also said that sometimes students might use phone messages to cheat during exams.

Some schools had tried to ban mobile phones. Some parents felt unhappy because they couldn’t get in touch（取得联系） with their children.

Many teachers said students should not have mobile phones at school, but if there was a good reason, they could leave their phones at the school office. They also said the main reason why the students should not have mobile phones at school: they were easy to lose from studies.

Many people say that they understand why parents would want their children to have phones, but they think schools should let the students know when they can use their mobile phones.
