A student newspaper reports that most students go to sleep at 1:30 am. Even if that’s an overstatement (夸张), it’s close to the truth. Scientists say teens should sleep nine hours each night. But that’s hard. Some are even “pulling all-nighters” (开夜车). These students must hand in their homework the next day but they haven’t done it. In the morning they don’t look healthy and you can tell who’s been doing it. One of my classmates did a survey on the topic. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!
Maybe our lack(缺乏) of sleep is because of laziness — I think I’m a rather lazy student — or maybe it’s because we have too much to do in American high schools. I usually go to bed around midnight. If I stayed up past 1:30 am, I wouldn’t get any work done. I’d be falling asleep at my computer. My classes begin at 7:30 am. I’m partly awake in my first class. By the second, I’m a little sleepy. By my third class, I’m sleepy. By midday I’m finally fully awake. But by 3:00 pm, I’m slowing down again. Yet I get more sleep than usual students.
Most American high schools seem to have a similar(相似的) problem with sleepy students. High school classes start at 7:30 am, so students have to get up one and a half hours before that to get ready and catch the bus. It’s believed that lack of sleep can be bad for both grades and health. Some schools are paying attention. Classes in those schools start at 8:30 am.

A city without cars would be very strange, right? But Venice is such a city.

Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands.  Seawater is everywhere around the city.

Even so, travel isn't difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go. People in Venice move from place to place by boat. They like to enjoy the scenery and cool summer nights while taking boat trips.  They can talk to other people as they go along.

Venice grew out of small islands in saltwater lakes when some Italians escaped from a war more than 1,500 years ago, and built homes there.

Water makes the city special, but it is also a big problem.

Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is the rising seawater. The temperature has risen over the years.  This has made the ice of the Arctic Ocean (北冰洋) rnelt( 融化).

Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater.

Scientists are trying different ways to stop the city from getting even lower.
