根据短文内容,完成下列小题。

    Is sleep important for children? A new study says yes.

    In America, most people don't get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can't sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their poor sleeping habits down to their children.

    In the study, Reut Gruber and some other scientists either added or reduced(减少) one hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect(影响) a child's behavior.

    Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After changing the children's sleep for five nights, the teachers had to record again. According to the two records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely(可能的) to feel sad and had more problems paying attention.

    The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children's behavior at school. "In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference," says Gruber.

(1)、According to scientists, what may cause children to sleep less?
(2)、Why did scientists do the new study?
(3)、Who helped do some records in the new study?
(4)、Who did the scientists find behaved better in the new study?
(5)、Was the study done in a laboratory?
举一反三
阅读下面一段短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词,每个空格只填一个单词。

    Giving a speech in front of your class can be challenging. However, you can do something to make it success. First of all, you need to do something about your topic. For example, choose a topic about something you like, such as something that interests you or someone who is close to you. Once you've chosen your topic, try to find useful information about it online or from the library. As you do this, write down the information that supports your ideas in a valuable way.

    Rehearsing(排练) your speech is also important. For this, you'd better write the script (讲稿) just like talking to your friends. Keep your script simple. Use interesting examples or stories to show your ideas. Once you finish your script, read it out loud to yourself and remember it. After that, write down 2 to 3 points that you may forget on a note card. Finally, you have to practice your speech in front of something or someone until you don't have to look at your note card.

    In the end, it's time to give the speech. At this time, stand straight and hold your head high. This will show that you're confident. Show your listeners that you're excited by smiling before you begin and throughout the speech. Pause(停顿) after finishing a sentence, or after saying an important point. It will allow you time to collect your thoughts.

    If you're out of breath while speaking or if your words start running together, you're most probably speaking too fast. If this happens, take a breath and slow down. While talking, look at your listeners, like friends. What's more, if you don't remember the next word or line, pause for one or two seconds to look at your note card. Before you begin speaking, take a deep breath, smile at your listeners, and then go on.

阅读下面短文,根据短文内容,完成下列各题。

    Mr. Guo is a teacher from Xi'an.  He asked his students to hand in their homework through a QR code(二维码). "We spent an hour or two in class learning how to generate(使产生) the codes, and in the end everything gets easier. "Said Mr. Guo, "When students finish the homework, they keep it on WeChat. Then, each student makes his own QR code and gives it to me. So I can cheek their work anywhere using my computer or telephone. "

    The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Mr. Guo scans (扫描) his students' QR codes, their homework appears on his phone, lie finds that their homework becomes more creative, with many pictures, music and even videos.

    Mr. Guo's students like the new way and think it is interesting. "We are living in the information age. Many students like to work with computers, which makes learning more fun. "Said Tingling, a student of Mr. Guo's.

    "The paper is not easy to keep, hut the code is easy to keep and share." Mr. Guo said," It is worth trying to use new technology in education. Education itself is a kind of creation. I don't want my students to fall behind the times. "

    However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it's unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the codes when they hand in their work, which doesn't take them too much time.  Also for teachers, it allows them to cheek the students' work at any time.  And it's also an easy way to share homework with other students.
