The Chinese Medical Doctor Association asked 8,200 people in China about their sleep. More than 36.3 percent of them said they often sleep badly. The study also finds that many students have only 5 hours of sleep a day. According to the US National Sleep Foundation, teenagers need 8.5 to 9 hours of sleep every night. What cuts into their sleeping time? Homework. Also, school starts early in the morning.
But bad sleeping habits also play a role. Do you like to have a look at your mobile phone before going to bed? The survey finds that 60 percent of people check their phones before they sleep. They read news, check their WeChat (微信) or chat with QQ friends.
It’s important for us to get enough sleep. We feel tired and think slowly. Besides, sleepy kids are often unhappy, says a study by the US National Sleep Foundation.
We can’t change our school time. But there are still ways to get better sleep. Stay away from coke, coffee and tea at night. They make it hard to fall asleep. Watch less television. Leave your mobile phone and tablet computer (平板电脑) on your desk.

Do you know you could get sick just by walking past a building? The bacteria(细菌) that cause Legionnaire"s disease grow very fast in large modern buildings.

You can be proud of yourselves, even if you can only make one or two of these green changes. The goal here is to limit carbon dioxide and other greenhouse gases, which are closely connected to the big problem of global-warming (全球变暖).
WAY 1: Bring your own cup to Starbucks. You’ll get a 10-cent discount, and it’s one less paper cup to end up in a dustbin. The store won’t create more waste when they throw away a cup.
WAY 2: Turn off your computer. When in standby mode, your PC is still using energy. Turning off a monitor (显示器) for 40 hours a week may only save $ 5 a month, but it reduces CO₂by 750 pounds.
WAY 3: Reuse plastic bags. Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag. The amount of oil it would take to make just 14 plastic bags would run your car for one mile.
WAY 4: Use recycled paper in the bathroom. Most of the toilet paper we use is made from trees found in forests. If every family replaced(替换)one roll of toilet paper with a recycled one, 424,000 trees would still be standing.
WAY 5: Plant a tree. Adding green to your garden is beautiful and earth-pleasing. Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year.
小题1:How many ways are mentioned(提及) in the passage?

A．Two.	B．Three.
C．Four.	D．Five.
