A tornado (龙卷风) is a kind of strong storm with air which moves in a circle quickly. They can move over 200 miles per hour and cause a lot of damage (损坏). As they move across the land, they can easily pick up cars, trucks, and even houses, and then throw them very far. It is important to find a safe place if a tornado gets close.

A safe place could be a basement ( 地下室) or the lowest floor. If you are in a home without a basement, try to find a first-floor bathroom or a small room without windows in the middle of your house. You should curl up (蜷缩) into a ball and cover your head and neck with your hands.

But there are some people who actually want to get close to tornadoes. They are scientists who want to learn more about tornadoes. One of the best ways to do this is to get as close as possible to the tornado. They use special tools to measure (测量) what is happening in and around a tornado.

One special tool is called a tornado probe ( 探测仪). Inside the tornado probe, there are sensors (传感器) to measure wind speed, temperature, pressure, and direction.

Some probes even have cameras, so the scientists can see and understand what it's like to be in a tornado.

To be able to get these measurements, the scientists have to get a tornado probe near or into a tornado. Scientists will try to guess where a tornado will go next. Then they drive to that location and put down the probe. If they do not guess correctly, they pick up their probe and try another place. If they are right, the tornado will go near or even right over the probe. Then they take all of the measurements

from the probe and use them to predict where future tornadoes may form (形成) and travel. And they can give people some warning to keep away from a dangerous tornado.

Quan Hongchan comes from Zhanjiang，Guangdong. She is {#blank#}1{#/blank#}great diving（跳水） player in the world. 

Quan was born on March 28，2007. She is the {#blank#}2{#/blank#}（three）among（在……当中） the five children in her family. 

She spends over seven hours practicing diving every day. It is difficult，    {#blank#}3{#/blank#} she practices it hard. 

It was a hard time for Quan when she just went to the sports school. She had to live far away {#blank#}4{#/blank#} her home. The girl cried a few times，but she {#blank#}5{#/blank#}（keep） on trying. "My mother was sick（生病的） and my family was poor，so I wanted {#blank#}6{#/blank#} （make） more money for my family. "Quan said. She was hard—working. She did very {#blank#}7{#/blank#}（good） at the Tokyo Olympics （东京奥运会） in 2021. 

Quan has good living {#blank#}8{#/blank#}（habit）. She gets up and goes to bed early every day. She never eats unhealthy food like ice—cream because her coach（教练） He Weiyi doesn't let {#blank#}9{#/blank#}（she） do so. 

Quan's dream is to get more champions（冠军） for China. I think her dream can come {#blank#}10{#/blank#}. "My father told me to stay true to my dream，"she said. She always tells herself to keep going. 

We usually send and receive information through the movement of our bodies. Body language can show different feelings. We often use gestures(手势) or body movements to show and express our mind. For example, when someone is giving a talk, he or she may often use his or her hands to emphasize(强调) points.

The victory(胜利) sign, the OK sign, the goodbye wave and the blowing of a kiss are all popular gestures in America. However, most of these gestures are not accepted(接受) by people in other countries. For example, the OK gesture means acceptance in America, but it has other meanings in other countries. In France, it means worthlessness(无价值), while in Greece it is a sign of quite disrespect(不尊重).

There are some other differences in the non-verbal(非语言的) messages of people of different sexes(性别). In American culture, men usually sit or stand with their legs apart and hands outward, while women usually keep their legs together and their hands at their sides. Women sit quietly than men most of the time. Women are also better than men at expressing themselves using gestures.

In short, body language is simple and useful, so we should learn how to use it in our daily lives.

Today, I am going to talk about life in the future.  {#blank#}1{#/blank#} Will life be like in the future? No one can answer this question.  Today, cameras in space can take {#blank#}2{#/blank#} (photo) of places billions of light years (光年) away {#blank#}3{#/blank#} the Earth.  Science is developing very fast and people know more about space.  With {#blank#}4{#/blank#} help of science, we may also visit {#blank#}5{#/blank#} (that) places.  We may have to {#blank#}6{#/blank#} (leave) the Earth to live in space {#blank#}7{#/blank#} the Earth will not hold so many people one day.  In the future, we {#blank#}8{#/blank#} (travel) very fast by spaceship.  {#blank#}9{#/blank#} (we) spaceships will be as large as a city, and every spaceship will carry more than 10,000 people.  There {#blank#}10{#/blank#} also many buildings in our spaceships, such as hospitals, schools, shops and cinemas. 

International(国际的) Nurses Day falls on May 12 every year. It is in memory of the birth of Florence Nightingale. Who was this lady?

Nightingale was one of the most important health workers in history. During a war(战争)in the 1850s，she worked with other nurses to care for English soldiers(士兵). She set many important rules for health care. Because of her habit of making rounds(巡诊) at night，people called her "the Lady with the Lamp(灯)". Later in 1860，Nightingale opened a health care school in London. She trained many excellent nurses in this school. 

Every year on this festival for nurses，a special activity is held in London. A lamp is handed from one nurse to another. This means that knowledge is passed from one nurse to another. 

Nurses make up more than half of all health workers，but there are still 5. 9 million more nurses needed in the world. The terrible disease(疾病) has reminded us of the importance of nurses. Without nurses and other health workers，we wouldn't be able to fight against diseases successfully.
