    Wake up, boys and girls! Put up your hand if you try to repair your tired body by sleeping in(睡懒觉)on weekends. A new study says the habit might not be a good idea for your health.

    The ten-day study came out in the magazineCurrent Biology. Volunteers were divided into three groups. The first group enjoyed nine hours' sleep each night. The second group was allowed to sleep only five hours each night. The third group was given five hours' sleep Monday through Friday.  But they were put back on the short sleep schedule the next Monday.

    Both the second and third groups ate more snacks at night and put on weight. They also saw a decrease (减少) in insulin sensitivity (胰岛素敏感性), a warning sign for diabetes (糖尿病). Researchers have long known a tack (缺乏) of sleep can increase health risks.

    "Even though people in the third group slept as much as they could on the weekend, it was not enough," said Dr Kenneth Wright, who led the study. "When they went back to the short sleep schedule the next week, their body failed to control blood sugar.

    So what should we do if sleeping in over the weekend is not a good choice?  Cut out the "sleep stealers" such as watching television shows or spending time on computers or mobile phones. Always remember. Getting enough sleep is as important as having good caring habits or doing exercise regularly.

    We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these three words daily: reduce, reuse and recycle.

    Reduce

    Reduce means "use less". Do not waste things. It saves money and causes less pollution. Do not order more food than you can finish.当你不需要的时候就把灯关上。Before you buy something new, think whether it is really necessary because maybe the old one is just as good!

    Reuse

    Reuse means "use again". Use things for as long as possible. Look after them so that they will last. Repair them if possible. Do not throw them away and buy new ones. Do not use paper cups or paper bags.

    Recycle

    Recycle means "change things into something else to be reused". We throw tons of rubbish away each year, and we have to make a change.Divide your rubbish into plastic, glass, paper and rubber. Develop a recycling policy for the whole community. Buy products such as recycled paper to help save trees.

This 12-year-old Girl Built a Robot to Find Plastics in the Ocean

    Anna Du was walking along the beach when she noticed plastics there. She reached down to pick them up, and quickly realized there were many more tiny pieces than she could deal with. It seemed impossible to clean them all up.

    Du, 12 years old at the time, tried to solve the problem like any good scientist-first, by doing a little research. That's how she learned that 8 million tons of plastics end up in the oceans every year.

    Then she got to work building something that could help solve the problem; a remote-operated vehicle(遥控潜水器), or ROV. Her ROV can move through water and find plastics on the ocean floor.

    The actually cool part of Du's ROV is the detection(探测) system. She uses a camera along with three different kinds of light to find the plastics. She also uses visible(可见的) light to find unnatural colors that might make the plastics stand out.

    "She has a very good engineering sense to break down a problem like this and then go after it," says engineer Casey Machado. "It sounds simple, but it's a level of thinking that's really amazing."

    Du started attending public events and workshops at a university when she was five years old, and so she picked up the engineering skills necessary to build her ROV. She says actually getting her ROV to move through water well was not easy. She failed many times, but she never gave up trying and testing.

    When asked about future plans, she mentions wanting to address the effects of climate(气候) change. "I think there are a lot of problems that could be solved with new inventions," says Du.

    Du thanks her parents, who for years have taken her to student outreach activities, for supporting her interest in science, technology, engineering and math (STEM). She says she has been able to meet students and scientists there.

    "I know I want to be an engineer because I like building things to help solve world problems," says Du. "But I'm not sure what kind of engineer I want to be yet."

    Trees are one of the oldest "citizens" of our earth. They keep our air clean, reduce noise pollution, improve water quality and provide food and building materials.

    Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to grow up safely. For example, many trees grow thorns to warn animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy.

    When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit.

    It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. The adult tree gives us shade, oxygen and natural beauty. It is also a great place for a tree house, or a place for us to read a book, listen to music and so on. If we give the adult tree proper care, it will go on to live healthily for many years.

    Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow or part of it becomes dead, it provides a home for small animals and is a source of food for many other animals.

    In many ways, the life of a tree is similar to our own life experience. When we are looking at the life of a tree, we learn that each period of life brings its own form of joy and challenge. Enjoy every minute of the life of the trees and look after the trees!

    Some people are nervous about living near rivers because rivers can cause floods (洪水). Every

once in a while, floodwaters rise higher than a house, ruining (泡坏) many things in the house.

    Such waste causes water to smell bad and pollutes the crops (庄稼) we eat. Water and crops in polluted areas can make people very sick.

    How do people decide where to live?

    Rivers can provide jobs and fun activities in a beautiful place. However, those living by rivers should be willing to accept possible problems as well.

    You've been learning words since you were a tiny baby. At first, you learned them only by hearing other people talk. Now that you're a reader, you have another way to learn words. What should you do when you come to a word and you think you don't know what it means?

Say it

    First, sound it out. Then say it to yourself.. Sometimes you know a word in your head but you don't know what it looks like in print. So if you match up what you know and what you read - you have the word!

Use context

    If this doesn't work, take the next step: look at the context - the other words and sentences around it. Read this sentence: When it rained, the dog looked for shelter in the doorway. . Rain and in the doorway might give you helpful information.

    If the context doesn't help, look at the parts of the word. Does it have any parts you know? These can help you understand what it means. If you don't know the meaning of miner, try looking at parts of the word. You might know that a mine is a place underground where people get coal and other valuable things. A lot of times, -er at the end of a word means “a person who does something”. So a miner might be someone who works in a mine.

Look it up

    If the three steps above don't work, you can look it up. .- either a book or online. Nobody knows the meaning of every word, but good readers know how to understand words they don't know.

A. Use word parts

B. Look at the words

C. It might sound like a word you know

D. You can find the word in a dictionary

E. Following some easy steps can help you

Answer the questions according to the passage.

    In recent years, with the development of technology, many popular apps (应用程序) have been produced. These days, an app has caught great attention. It is Douyin, a video sharing app. Douyin first appeared in 2016. Now it is many people's favorite app, especially the young.

    With Douyin, users can record videos, edit (编辑) them and share them online. It is very easy and interesting. We can share our videos with our friends with just a tap on the mobile phone screen. What's more, it's a great way to spend our free time by looking through those funny videos.

    However, every coin has two sides. The app also has bad things. On the one hand, some people spend long hours on the app, which is harmful to their health. On the other hand, users can also find some bad things on the app. Such thing is unhealthy and unsuitable.

    In my opinion, Douyin should check the videos before they are uploaded (上传) in order to keep a healthy environment for its users. Douyin is not good for teenagers. We should not use it too often.
