How do animals communicate (交流) with each other? They have special “languages”. In fact, they are using signals (信号). Different signals have different meanings.

For example, when a bee (蜜蜂) finds food somewhere, it flies home quickly. It can't speak, but it can tell others by dancing. Other bees will know where and how far the food is.

Some animals show their feelings by making sounds. For example, when a dog is angry, it barks (吠). At this time, you'd better stay away from it. Birds can make several sounds to show different meanings. Sometimes we humans show feelings by making sounds instead of by speaking. For example, when we feel painful (疼痛的), we cry“Oh!”or“Ouch!”.

We humans have languages and words. We can communicate face to face by speaking. We can write down what happened in order to remember clearly. We can also send (寄) messages to people far away. But animals can't.

Strong earthquakes hit the east of Japan in the afternoon of March 11, causing several meter-high tsunami(海啸), which killed more than 10,000 people in areas along the coast. Several nuclear plants(核电站) at the coast were broken by the earthquake and tsunami. People living near the plants have been asked to move away. People living within 30 kilometers of the first plant are asked to stay indoors and close all windows.
The breaking of the nuclear plants is causing electricity shortages(电力短缺) in Eastern Japan. As a result, electricity is cut off for 3-hour periods in the area of Tokyo and some other areas during daytime. In order to save electricity, some shops, restaurants and tourist places in the areas are closed for some time every day. But all major airports and train lines are still open and operating.
For the above reasons, tourists are advised not to visit the eastern areas in the near future. Visits to Western Japan are not affected by the event. People who plan to travel over the coming weeks and months are advised to pay attention to the situation for a few more days before making decisions.

阅读下列短文，根据短文内容，回答下列问题。
                                                                                   Save water, save lives
   A BOTTLE of water may not seem like much to you, but it can save the day for people who live in drought-hit (遭受旱灾) areas in China.
In the past few months, some places in southwest China experienced a serious drought. In Yunnan, Guangxi, Sichuan, Guizhou and Chongqing, there has been very little rain since last autumn. Crops died, the land cracked, and wells (井) and rivers dried up. More than 20 million people are having difficulty finding safe drinking water.
   After learning about the drought, many people around the country helped by giving water, money and other resources.
   Last week, China asked every member of the Communist Youth League (团员) and Young Pioneers (少先队员) to give one bottle of water to the drought-hit area. Students in primary schools and middle schools quickly joined the activity.
   “A bottle of water isn't much, but thousands of bottles will be of great use,”said Zhang Zihao, a middle school student at Tongling No 1 Middle School in Anhui.
   In Yuhua Primary School in Xi'an, 900 students bought over 100 bottles of water with their pocket money. They also wrote their wishes on the bottles.
   The serious drought has also made students realize the importance of saving water.
Students from Nanshan Middle School in Huizhou in Guangdong went on the street to tell people to take part in water-saving activities.
“I heard that some children in drought-hit areas don't have enough drinking water. They have to drink muddy (泥泞的) water. I feel really sad about that,” said one student. “I decided to take a shower twice a week instead of every day to save water.” he said.

      Growing mushrooms(蘑菇) is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.
      Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.
     When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don't have enough time to spend taking care of everything yourself, dome helpers may be the best choice.
      After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides(农药) or any other animals or something that could be dangerous to them. That is the worst part of mushroom developing. Protect your mushroom farm well with a fence(围栏) or a gate so that only you and your workers can get in and out.
     Mushroom growing is not difficult and it is easy to get stared in the world of farming. You will soon possibly be able to provide some of the great cooks of the world with high quality mushrooms that will be enjoyed by thousands of people all over the world.

Since ancient times, human beings have looked up at the night sky. Comets (彗星) and meteors (流星) flying through the blackness were seen as signs from the gods. They were used to tell the future of human lives.

In 2013, a meteorite shower hit an area in Russia. It injured around 1,200 people. In ancient times, this would have been a strange and terrible experience. Today, thought, science offers simple explanations for the occurrence (事件).

Meteorites are small pieces of debris (碎片) that float around in space. Sometimes, they come near a planet, such as Earth. When they enter our atmosphere, they often heat up and become very bright. This is why they are sometimes called “fireballs”. They are usually made of metals, such as iron (铁), and other minerals (矿物). The Russian meteorites were stony, with iron making up 10 percent of them.

Meteorite showers, such as that in Russia, happen when a large meteor enters the Earth's atmosphere and, due to heat, breaks up into small parts. Most of these are very small — smaller than a grain of sand — and so don't even make it to the ground. But others can cause a lot of damage.

The meteor in Russia weighed 10 tons when it entered our atmosphere, and broke up about 20-30 miles (30-50 km) above ground. The sky was filled with bright lights and loud noises. Many windows were broken. The damage cost Russia around 206 million yuan.

Imagine a perfect day: the weather is good and everything seems fine. When, suddenly, your mobile phone loses its signal, the television has no programs, and you can't get online with your computer.

What has happened? These are just the types of problems a solar storm（太阳风暴）might cause. You may not think of storms as putting our society in danger. But today, a solar storm is as serious as other bad events, such as earthquakes.

A solar storm is caused by solar flares（太阳耀斑）: large explosions（爆炸）near the sun that can give off lots of energy. The strong energy can stop the satellite systems（卫星系统）that control our computers, telecom networks and so on. These storms can even cause the power to go out for weeks or months.

In the past few months, scientists have recorded some of the strongest sun flares in years. The most recent one happened around Valentine's Day, 2011. It caused radio and satellite signals to go down in some northern cities in China.

“Solar flare activity is going to be much worse than what we've seen in the past. We're not talking about a few cities losing power, it could be half of the country, maybe more.” SolarStormWarning.com, a US website about space weather, warned.

Scientists say that little can be done to predict such a storm. Governments around the world are trying to work together before the next storm, although they are not sure when that may happen.

Here is a page from a magazine called Future. Read the following information about things that may happen in ten years.

Cars will run on solar power (太阳能) and will be much cleaner. They will be much safer. For example, if you are too close to another car or if you are driving dangerously, your car will slow down or stop by itself.

New cities will have to be built in the sea. Some cities on water will have two levels(层). People will live on the upper level; the lower level will be used for traffic, shops and factories.

Biotechnology(生物技术) will make food better and healthier. Plants without insects or illnesses (病虫害) will be developed. The taste of fruit and vegetables will be better and food will be kept longer.

Many new ways to cure(治愈) illnesses will be found. People will use products of genetic engineering (基因产品) to cure more illnesses. However, some new illnesses will appear.
