When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(温室气体). This means that every time you use electricity you help make global warming worse!

Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.

Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let’s try one of these top ideas:

(1) Try to use less electricity. Turn off lights, your television, and your computer when you’ve stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.

(2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.

(3) Don’t throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐烂) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It’ll make you feel great! And it’ll help the Earth.

1.If we _____, we may make global warming worse.

A．use less electricity                      B．drive a car on sunlight

C．plant trees                            D．throw away rubbish

2.We may use more electricity by______.

B．the more electricity is used, the more greenhouse gases are produced

C．more electricity is used, less greenhouse gases are produced

D．less electricity is used, more greenhouse gases are produced

Zach Linsky, 11, watches TV for 3 and a half hours a day and plays video games every other day. Zach, a sixth grader in Washington, D. C., is an American. But unlike many kids, he doesn’t have a TV, VCR, or computer in his bedroom. He only has a boom box (手提录音机).

The survey of 3,155 kids, aged 2 to 18, shows that they spend 5 hours and 29 minutes on average(平均的) a day using some types of media outside of school, including 2 hours and 46 minutes watching TV, 21 minutes on the computer, 20 minutes playing video games, and 8 minutes on the Internet. The good news: The total includes 44 minutes spent reading.

The survey also shows that those aged 2 to 7 spend 3 hours and 9 minutes watching TV every day and shows that 32 percent in that age group have TV sets in their rooms. Among those aged 8 to 18, 21 percent have computers in their rooms, 65 percent have TV sets, and 61 percent say their parents don’t stop them from watching TV. Nearly 1 in 4 say they watch more than 5 hours a day.

“Kids are living much more lonely lives than ever before,” says Kay S. Hytnowitz. “They just disappear into their rooms and spend all of their time with these media.”

You might have noticed that sometimes, when you’re playing mobile games or making a video call, the picture suddenly freezes(卡顿)because the network speed is too slow. When you try to download a movie on your phone, it seems to take forever.

These annoying things will soon become things of the past, as China just issued commercial licenses(发放商业牌照)for 5G networks on June 6. This means that China’s telecommunications(电信) companies will be able to offer 5G network speeds for mobile phone users.

The “G” stands for generation (代) . 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and Internet, and 4G made all of these things faster. So what will 5G bring？

First of all, 5G is so fast that it will allow us to download an entire HD movie in a second. The delay(延时) between sending and receiving data will be shortened. Now, 4G takes about 100 to 200 milliseconds(毫秒)，while humans have a reaction time of about 200 to 300 milliseconds. But 5G will get the delay down to 1 millisecond or less, which is almost real-time.

Because of this increase in speed, it will be possible to create and use new kinds of technology. Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay. Self-driving cars will be able to drive more safely because they can smoothly communicate with other cars, traffic lights and road Sensors (传感器). 5G also makes the Internet of Things(IOT物联网)possible.

All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.

1.From the first paragraph we can know that________.

A.people can’t download movie at all on the phone

B.making a video call is impossible for phone users

C.sometimes the network speed is too slow to use

D.mobile games can’t be downloaded on the phone

2.What happened on June according to the passage？

A.China just gave commercial licenses officially for 5G networks.

B.Every mobile phone user could improve the network speed

C.Most mobile phone users didn’t use 4G anymore.

D.All the mobile phones are much cheaper than before.

3.Which of the following is NOT true according to the passage?

A.5G will make people’s life much easier and more convenient.

B.Self-driving cars will become safer because of the use of 5G.

C.Using 5G to download something doesn’t take any time at all.

D.5G can make people download an entire HD movie in a second.

4.We can find the passage________.

A.from an ad B.in a newspaper C.in a storybook D.in science fiction

Is reading better than watching TV? I believe it is. Is reading better than playing video games? I’m not so sure if it is. If learning is important to you, but not necessary so，and if pleasure is what you want，these activities can be pleasant in their own way. Reading might be better than many activities if you want to educate yourself and improve your chances of succeeding in your work.

If you’re serious about creating the habit of reading，what’s important is finding a time you can read every day—often that’s early morning or late at night，or both. For others, it might be during their lunch break. You only need to read for 10 to 20 minutes a day to form the habit.

Then, you need to find a place that’s comfortable. Make sure it has good lighting, the temperature is nice and you’re in a good chair. Or you can find some place that you can relax in without falling asleep, although there’s nothing wrong with sleep.

Next，be sure to shut off the TV，Internet，cell phone，radio, or other music. Let reading be a quiet time. Mark an “x” on your calendar every day you read, and try to keep your unbroken “x”es going as long as possible. A habit is much easier to form if it’s something you enjoy, not something you are made to do. So make the time, you spend reading a joy. I’ve been a lifelong reader, so the pleasure of a good book is one of my favorite things in the world. I love to lose myself in the world of a book.

When you are watching TV, you will notice that more and more famous stars make the ads on TV. Many people believe them because they are famous. But have you ever thought if the ads are real or not?

In the past few years, lots of stars have been on TV or newspapers as spokesmen(代言人) of some products(产品), such as Sanlu Milk and Haojixing Study Machine. People spent much money on these products, but at last, many of them were not like what the stars said. More and more people are very angry with the famous actors for making the ads after the accident of Sanlu Children Milk.

What are the public’s ideas about the famous people making ads on TV? Do you agree that the famous people should take responsibility (负责任) if the products have any problems? A research shows that about 36% think it wasn’t the famous stars’fault(过错)，but they all think famous stars should give out the money they got from the ads or the charity(慈善机构).More than34%think the famous stars must take responsibility.They are dishonest and lose themselves in the public.
