There are many wetlands (湿地) in China ‒ and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are {#blank#}1{#/blank#} them. They are in Yancheng, Jiangsu Province. They are {#blank#}2{#/blank#} to many different kinds of animals. The world's {#blank#}3{#/blank#} Milu deer nature reserve (自然保护区) is on these wetlands. More than 700 Milu deer live there. There are not many red-crowned cranes (丹顶鹤) {#blank#}4{#/blank#} in the world, but every winter, you can see some in the red-crowned crane nature reserve in the Yellow Sea Wetlands.

    The {#blank#}5{#/blank#} in the wetlands is neither too high nor too low. There is  {#blank#}6{#/blank#} rain and sunshine, too. They are a good place for wildlife. But offering food and shelter for special kinds of animals is not the  {#blank#}7{#/blank#} reason we need to protect wetlands. Wetlands are important {#blank#}8{#/blank#} they also prevent floods. But some people want to {#blank#}9{#/blank#} the wetlands to make more space for farms and less space for wildlife.

    More people are beginning to realize the {#blank#}10{#/blank#} of wetlands and wildlife. Every year, on Feb 2, many activities are held to teach people about the wetlands.

    The summer holiday is coming. Try to take some time off from school and have fun. Here are some ideas for planning your summer holiday.

    First of all, joining a club is a good idea! You can join a music club, a sports club or an art club, it's good for your future and the teachers in the club can give you some good advice (建议). You can also make some new friends.

    Doing something good for society (社会) is also great. There are many volunteer programs(志愿者项目) for you to choose, such as looking after the____①___or the young, cleaning the streets, planting trees or keeping the traffic(交通) in order. You know that students can also make the world better.

    Did you ever live with another family? You can join in a program___②____"Meeting a New Family" .Two families exchange their children for some time so that they can learn how to get on well with others.

Summer camps are still popular today. An English summer camp can be a good one. You can not only make friends but also learn English.

Now students' English handwriting（书法）gets worse and worse. That makes their teachers feel worried. Is your English handwriting beautiful? If not, here are four steps that really work!

u  Using paper with lines (线条)

Using paper with lines can keep you writing straight when you write English words or sentences. Those lines on the paper can help you to write words in the right size.

u  Slow down

If your writing is hard to read, try slowing down a little. For some kids, going slower makes the handwriting clear. If you write too fast, it's hard for you to stop where you should, and even worse, you may make more mistakes.

u  Hold your pencil right

When you hold your pencil the correct way, writing is much easier. Try to be relaxed and don't hold the pencil so hard while writing, and then it makes your handwriting nice and clean. If you do so, people will think you are a student with a good habit.

u  Draw more pictures

Drawing can improve your handwriting. You need to use the skills to control(控制) your pencil better when you are drawing pictures. If you have no time for drawing at school, you can practice it at home.

Some have good handwriting and some don't. Anyway, handwriting is very important. You need to take time to improve it.

    Imagine you are taking a walk on the beautiful beach. Just then, your feet step over something and you hear a crack (噼啪声) —an empty plastic bottle. Things like this are happening more often because of sea rubbish.

    Studies show that 80%of all the waste is from the land. The waste is mainly plastics (塑料制品) which are really hard to degrade (降解). So the rubbish will remain there for a long time. Some of the pollution is caused accidentally. For example, about 10,000 product-filled boxes are lost at sea every year from business ships. Sometimes people just throw things into the water from boats or land. Many large rubbish areas are formed in the North Pacific Ocean.

    Thankfully, the situation isn't ignored (忽视). Groups like the National Oceanic and Atmospheric Association (NOAA) are taking action to help clean the sea. Since 2006, 76 projects have cleared out 3,814 metric tons (公吨) of rubbish from the sea. Methods of rubbish cleaning include using machines to remove (移除) the waste away from the surface of sea water. Besides, special nets are set by the mouths of rivers to stop the rubbish before it reaches the sea. If everyone does his part, sea rubbish seems like a problem that can be solved.

Think about the colors of fruit and vegetables: the red of tomatoes, the orange of carrots, and the purple of grapes.

You can eat fruit and vegetables of all colors—green, yellow, blue, purple and white. Each color is important to our health. These colors work together for our bodies.

Red gives us a healthy heart. Red helps improve our memory (记忆力). Yellow is good for our eyes. White can reduce (降低) cholesterol. Green is good for our eyes, too. It also gives us strong bones and teeth. Blue helps us keep a good memory as we grow old. It also helps our heart. So when you are buying or eating fruit and vegetables, remember to try fruit and vegetables of different colors.

Imagine （想象） walking into a movie theater without being greeted by the smell of popcorn. It's hard to believe, isn't it? For many people, popcorn goes hand in hand with movies. They can't have one without the other. But 1  did this happen?

The 2  between the two is younger than you may think. In the mid-1800s, popcorn was already a popular snack in America. Vendors sold it on the 3  . People, especially kids, loved this street food. In the early 1900s, vendors started to sell popcorn 4  movie theaters.

However, theater owners didn't like popcorn. They believed it would make the experience of watching a movie 5  enjoyable. Eating it would make too much noise during the silent movies.

Later, when movies added sound, the 6  noise problem went away. More and more people went to the movies. Some of them even secretly（秘密地） took popcorn into the theaters. Later, more movie theaters 7  . Some of them agreed people to eat popcorn while they were watching movies.

In the 1930s, the theater owners found that people didn't need to buy popcorn from street vendors. Because popcorn was 8  to make, they could make and sell it themselves. They did that and the smell of popcorn drew more people to their theaters. The 9  made a lot of money, and people enjoyed themselves at the movies.

Today, popcorn is still an important part of the movie-going experience. Roles, a man who once ate three bags of popcorn, said, "People come to theaters sometimes just for the 10 . They don't even care what is playing!"
