Most plant will die if they don’t have enough water. But one plant, called the resurrection（复活）plant, seems to come back to life after it dies. This plant can still be there after a long time of terrible drought（久旱）because it travels to look for water. Many people say that one difference between plants and animals is that animals move from place to place to find food and water, while plants cannot. But in the desert areas of American West, the resurrection plant can move around to get what it needs, too.
When there is lots of rain, the resurrection plant grows like any other plant. It sends roots（根）down into the ground and has green leaves（叶子）. But when there is little water, the resurrection plant pulls（拉）its roots back up and dries up. It turns into a brown ball of seemingly dead roots and leaves. This brown ball goes through the desert with the help of the wind.
As soon as it touches water, the resurrection plant begins to act like a normal plant again. Its leaves turn green once more as it starts to grow. It is resurrected or brought back to life again in a new place. Because this plant can live a long time with no water, it has become a popular house plant. For anyone who always forgets to water his or her plants, the resurrection plant can be a fantastic gift.

Glaciers are large pieces of ice that form in high mountains or near the poles（极地）over many years. They are made up of fallen snow that gets pressed and move slowly over land. Glaciers are helpful for scientists to learn about what the weather was like thousands of years ago.
Glaciers cover around 11% of the earth’s total land area. They form the largest reservoir（水库）of fresh water on the planet. In fact, they store about 70% of the world’s fresh water. The world’s largest glacier is Lambert Glacier in Antarctica, about 400 km long and 2.5 km deep!
Earth’s glaciers are melting（融化）faster than scientists thought. A study shows that we are losing 369 billion tons of snow and ice each year. Because of warming weather, the melting glaciers are adding more water to already rising seas.
Icebergs are large pieces of ice that have broken away from glaciers and ice shelves. Icebergs float（漂浮）in the sea. Most icebergs are white. There are also blue icebergs. Surprisingly, there are green icebergs in Antarctica. Scientists found green icebergs have 500 times more iron than glacial ice. This is an important finding, as these green icebergs can send iron to far parts of the ocean to tiny sea plants.
We can only see about 10 percent of most icebergs. This is where the phrase “tip of the iceberg” came from, meaning we can only see a small part of a large problem.
Icebergs are dangerous to ships. The underwater ice can easily tear（撕开）a hole in the bottom of a ship. In 1912, the Titanic, on its way to New York, hit an iceberg and sank. More than 1, 500 people died.

We have to accept the truth: Sometimes, we just want to shout out loud.
For example, we all have days like this: When we just cleaned our room, the dog made a mess on the floor. Or our friend called to tell us he or she couldn’t come at the last minute after we cooked dinner for him or her. We may be really angry but we tried to bear(忍受) things like those. According to ancient Chinese wisdom(至理 名言), we should shout in a loud voice instead of keeping quiet. In fact, it’s good for our health.
“Chinese people pass on the practice as a part of traditional medicine,” said Mrs. Li, a 60-year-old woman from Hangzhou. “My parents taught me to do this. It ’s a part of our folk(民族) culture.”
Mrs. Li is a member of a group of people, and she loves shouting. Each morning, she and some of her friends climb to the top of a hill and let out loud shouts before starting their daily exercise. They believe that shouting is good exercise for them and it brings them a lot of fun.
“Sometimes I shout out and others shout back,” said Mrs. Gu, another shouting lover. “It makes you happy. You laugh and then you feel very comfortable.”
Dr. Peter Calafiura, an American doctor, agrees that shouting can have a good influence(影响) on people’s health.
So, next time you start your morning run, why not try to shout out first? It will make you healthier.
1. Who taught Mrs. Li to shout out loud to make herself feel better? (No more than 2 words)“Zero calories (卡路里) can’t put on weight.” Diet soft drinks are often advertised in this way. But are they really a good choice?
Some people think diet soft drinks are healthier because they don’t have sugar or calories. They think drinking these drinks can help them lose weight.
In fact, diet soft drinks do have some sugar, although very little. Usually, when there is 0. 5 grams (克) of sugar or less in a 100 gram drink, we call it a diet soft drink.
Although they have little sugar, diet soft drinks still taste sweet by using artificial sweeteners (人工甜味剂). They have very few calories.
But when you eat sweet-tasting things like sugar, it hits your brain and makes you want more. Your brain tells your body to prepare itself for more sugar. When you drink a diet soft drink, the brain receives the “sweet signal (信号)”, but no sugar arrives. Since the brain is fooled, it still wants more sweets.
Some people drink diet soft drinks and they don’t drink water. This is not a good choice. Diet soft drinks can make your teeth bad and let you not want to eat. The additives (添加剂) in these drinks are not good for you either.
1. Do any people think diet soft drinks are healthier because they don't have sugar or calories?2. What is a diet soft drink?
3. Why isn’t it a good choice for us to drink diet soft drinks?
4. In your daily life, do you drink more diet soft drinks or more water? Why or why not?
One day, you open the fridge(冰箱) and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She doesn't want to waste food. She cuts off the moldy part and eats the rest. Is it safe to do this?
Mold can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad – and it's not safe to eat.
If you find mold in soft food, just throw it away. There is some water in soft food, such as bread, tomatoes or hot dogs. This allows mold to easily grow. Bacteria (细菌) can also grow along with it.
But it's easy to remove(去除)mold from hard food. The mold can't grow very deeply inside this kind of food. It's OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.
Most kinds of mold is bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌) can be used to make many kinds of cheese. The cheese is safe to eat – and it's quite delicious as well.
1. Why does the mother refuse to throw the moldy food away?2. What color is mold?
3. What should you do if you find mold in bread?
4. Can the mold grow deeply inside hard food?

These days schools don’t allow students to bring mobile phones to schools. Many parents are worried. How can they connect (连接) with their kids? Well, smart watches may be the answer to their worries. Smart watches are like small computers. They usually tell time and count a person’s steps. Most smart watches connect with smart phones and they let the users make calls, and send and receive messages. Often smart watches have microphones (麦克风) and speakers. Some even have cameras.
Children are too young to have a mobile phone, so many parents buy smart watches for them. They are less worried because they can call their children at any time through smart watches. Also, many smart watches have GPS trackers (追踪器) where their children are, so they know if everything is OK.
But now some groups in Europe say many smart watches are not as safe as what we think. Some watches allow more than parents to track where the children are. They also allow anyone to send the children a message. People can also control the watches from far away to watch and listen to the children. To be safe, anytime a smart watch makes a call or sends a message or GPS information—the information should be processed (数据处理). So no one else can get the information.

Henry, Paula and Millie write for the school newspaper. They have written the short articles below to help students improve their memory.
A great way to help you remember something is to imagine a picture of it in your mind. If you make the picture big, strange (奇怪的) or silly, you will remember it better. For example, we can image there is a mile between the first letter and the last letter. This makes it the longest word in the world. Remember: a picture is better than a thousand words.
—Henry
A good method for remembering the spelling of a word is to make a short sentence with each letter of the word. For example, if you want to remember how to spell the word “because”, you can use the sentence “Big elephants can always understand small elephants”.
—Paula
You will forget something very quickly unless you understand it well. For example, you may have trouble remembering the steps of the water cycle. However, it is easier to remember them if you understand how the water cycle works.
—Millie

There are far too many mysteries in this world that we have yet to discover.
In a small town of Gryfino in Poland lies one of the world’s unanswered mysteries. There is a small group of pine (松树) trees with a strange shape. From the bottom, these trees grow with a 90-degree sharp bend (弯曲) northwards, but then go back to grow straight up into the sky. People call the area the Crooked (弯曲的) Forest for their look.
According to the scientists, the pine trees there were planted in around 1930. Though they are strange in shape, these trees are generally healthy and can grow nearly 15.24 meters.
Nobody knows exactly what happened to the pine trees in this strange forest. But there are still many guesses at the mystery. Some suppose that the gravity (重力) in this area has caused the trees to grow bent northwards. But it seems that this guess isn’t so forceful, because gravity only pulls things downwards and doesn’t make them bend. Others guess that the heavy snowfall in the area weighed down the trees as they were small. However, if that is the case, how would they explain the other normal trees in this area? Another guess is that it may be the work of aliens (外星人). This is the most interesting but also the most impossible reason. Probably they have watched too many science fiction movies before. The most widespread and most probable reason is that local farmers shaped the trees when planting them then. During those times, it was common for farmers to shape their plants for special purposes. For example, these strange-looking trees might be used as ship-building materials.
However, there is no evidence (证据) to support any of the guesses. The secret behind the Crooked Forest is still waiting for us to discover.

Can you imagine a world without chocolate? According to chocolate makers, it could happen if we don’t act soon.
One of the main causes of the chocolate shortage (短缺) is because of less production of cocoa (可可). New plant diseases and little rain in Ivory Coast and Ghana, the world’s largest producers, have reduced cocoa production by 40 percent in the past 10 years. What’s worse, many cocoa farmers are changing to easier-to-grow crops in order to make more money.
Therefore, what we can do is to increase cocoa production. To prevent more farmers from changing, researchers at the International Cocoa Control Center are trying to create new cocoa plants that are stronger and faster growing. But first they must make sure the new plants are safe to grow.
First, each new plant is stored at the Control Center for six months to make sure it is healthy. It is then planted in the Center’s fields, studied and tested for another two years. Only after scientists are certain that they’re disease-free, will the plants be sent to farmers who grow them.
To create new stronger types of cocoa, scientists at the Center are combining the best parts from different cocoa plants. Though the world is facing a serious chocolate shortage, they still believe that there is now hope!

Almost everyone likes flowers. Of all kinds of beautiful flowers, I like lotuses best. Perhaps you wonder why I like lotuses more than the others. People always throw lotuses into the dirty pools which may be out of use or even badly polluted. The earth is deep and black. The water smells terrible. But lotuses don’t mind at all. They don’t feel sad. They just stay in the earth and try their best to sprout, and they do what they can do to get much nutrition as they can from the earth around.
