A Pioneer for all People
Though he was one of China's most famous scientists，Yuan Longping considered himself a farmer，because he worked the land to do his research.
Known as "Father of Hybrid Rice （杂交水稻）"，Dr Yuan graduated from Southwest Agricultural （农业的） College in 1953.From then on，finding ways to grow more rice was his life goal.As a young man，he saw the great need for increasing the rice production.At that time，hunger was a serious problem in many parts of the countryside.Dr Yuan searched for a way to get more rice with the same size of the fields.In 1974，he became an agricultural pioneer in the world to grow rice that has high production and that is called super hybrid rice.In the 1980s，he went around the world and gave advice about growing rice to farmers in other countries.In 2004，he won the World Food Prize for his work.
Dr Yuan was quite satisfied with his life.He would much rather keep time for his hobbies.He enjoyed playing the violin，swimming and reading.Spending money on himself meant very little to him，so he gave millions of yuan to help some researchers with their research in farming.
Long ago Dr Yuan had a dream about rice plants as tall as sorghum （高粱） .With his hard work，he grew the rice that could feed more people.President Xi Jinping praised him for his great contributions （贡献） to China's food safety and world corn development.

It's 2050.The Earth is dying，and moving to Mars seems to be the only way out for humans.A team of American astronauts （宇航员） begin to search on Mars.This is what the movie Red Planet begins with.Known as the Red Planet，Mars is the favourite of writers and filmmakers.
Mars is the fourth planet from the Sun and the next planet beyond the Earth.Mars is the only planet whose surface can be seen from the Earth.It is about half size of our planet.
The surface of Mars is more like the Earth than any other planet.But it is further from the Sun than the Earth，so temperatures on Mars are much lower.Plants and animals can not live now on Mars.But many scientists still believe that such life may have been on Mars long ago.
On 6th August，1996，scientists discovered a piece of rock from Mars，which fell to the Earth 13，000 years ago.10 years later，some scientists still didn't accept that there was life on Mars.People may not be sure about life on Mars until a sample （样本） of life is brought back.Some further researches are being done in many countries.If you want to know more，please click www.spaceexploration.com.

Li Tao，a Junior 1 student，was quite busy over the past winter vacation but not just with homework.Li，together with his 10 classmates made a volunteer group to call on people to join in The "Clean Your Plate Campaign" （光盘行动） .
The 11 students went to many restaurants and told people the importance of saving food. "Excuse me，do you know that 950 million people around the world still haven't got enough to eat？Please don't waste food." They would say that hundreds of times every day.
China in these years has serious problems with wasted food.CCTV reports that the food Chinese people waste every year is enough to feed 200 million people for a year.
Chinese people are well ﹣ known for being generous （慷慨的）.Many even feel that they lose face if their guests have eaten all the food.
To reduce food waste is a big task，and it needs time.It's important that everyone should do their bit，just like Li.Did you finish your meals today？
Judge the following statements True（T） or False（F）.

（2）The 11 students went to the same restaurant and said the same words many times.
（3）The problems with wasted food in China are serious.

So，it's exam time again.Have you done the necessary work to get good marks？Sleeping with the textbook under the pillow（枕头）doesn't work.The best way is to space your practice out，rather than cram（塞）it all together.Just as a scientist called Tom Stafford advises，if you organize five hours of study into one hour a day，you'll remember more than what you study for five hours on one day.
▲Get pens and paper and start working!Students who can test themselves earlier will be better at retrieving the knowledge from the memory and keep it in the long run.John Dunlosky，a professor in the US，suggests that "you start by reading a textbook with your favorite pens and colors，and then write down the important ideas on small cards.While doing so，you actually try to test yourselves on them."
Good revision（复习）should give you confidence，but if you are still worried，it's not harmful to follow some special customs.In Japan，it seems to be a tradition for students to eat Katsudon before a test.This is a bowl of rice with egg and pork pieces.The name of the dish makes people think of the word "katsu"，meaning "winning".For some students in South Korea，the key to success is not washing their hair before an exam，because they believe they could wash all the knowledge out of their heads.And in different parts of the world，there are always those who believe in their "lucky underwear".
The bottom line is that you need to study，eat a good meal，sleep well on the eve of the test，and believe that your efforts will pay off.
Good luck in your exam!

Science is the best way we have of finding out about the world.Scientists collect evidence（证据）.They have ideas about the way things work.Science tests those ideas.Sometimes the test will show that the idea is not correct.If the idea passes the test，it adds to our understanding.

Scientists make predictions.They say something about the future.They might say 'if I do this，then I think that will happen'.Isaac Newton was a famous scientist.When he shone white light through a glass prism，he saw a spectrum （光谱） of different colors.Newton predicted what would happen if he shone the spectrum through a second prism.He thought the colors would come together and he would see white light again.He tried it.He shone a spectrum through a second prism.He was right.The colors made white light.He discovered that white light is made up of many colors.

Most children are taught the virtue （美德） of honesty from stories.The well﹣known story of Pinocchio teaches the importance of telling the truth.Every time Pinocchio lies，his nose grows longer and longer.Another story is about the boy who"cried wolf." In the end，he loses all his sheep and the trust of his fellow villagers because he tells lies many times.These types of stories show children that "honesty is the best policy." Still，if thisis the case，then why do so many people lie？The fact is that people lie for many reasons.
One reason people lie is to minimize （减少） a mistake.While it is true that everyone does something wrong from time to time，some people do not have the courage to admit their errors （错误） because they are afraid they will be blamed.For example，students might lie to their teachers about unfinished homework.They might say that they left the work at home when，in fact，they did not do the work at all.These students do not want to get in trouble or seem irresponsible，so they make up an excuse﹣ a lie﹣ to save face.
Another reason for lying has to do with self﹣protection.Parents，particularly those with young children，may teach their children to use this type of"protective" lie in certain circumstances （状况）.What should children do if a stranger calls while the parents are out？Many parents teach their children to explain that their mother and father are too busy to come to the phone at that time.In this situation，protective lying can mean greater safety.
People lie for many reasons，both good and bad.Lying to keep the peace or to stay safe can have positive results.However，lying to stay out of trouble can lead to more trouble in the end.Understanding the motives behind the impulse （冲动） to lie might minimize this habit of lying.

Water is important to all living things but some areas in the world are short of water a lot.So we should try to protect and save water.
A group of students from Zhejiang University have successfully developed an"air hand﹣washing machine".The machine uses an infrared ray induction system （红外线感应系统），which can feel the presenceof our hands.If it feels there are hands，the water with the air will come from the tap.And it has been proven that it is nearly as effective as traditional hand﹣washing.It uses only ten percent of the water that regular hand﹣washing does.The students have even set up a company to introduce the product to the public.
Li Qizhang，a member of the team that developed the machine，told a reporter that a model of their machine had already been placed in a classroom building at the university and it worked very well.
In 2014，a student called Chen Puyang first thought of the idea while he was washing his hands.Washing one's hands uses a lot of water，Chen thought.Would it be possible to replace the water with air？ Others may not give the question a second thought.However，for Chen and Li，who were studying fluid mechanics （流体力学） at the time，this was considered to be an excellent idea.
Soon，Chen，Li and several classmates started on the project.After a year of research，the team cam up with a gravity﹣driven （重力驱动） hand﹣washing machine successfully.
