Yuan Longping， a great scientist，is the first person to develop a kind of hybrid rice（杂交水稻） which helps fight hunger in China．
Food was a big problem in China in the past． This was because China had 22 percent of the world's population， but only 7 percent of its farmland．In the 1960s， China suffered （遭受）serious hunger．Millions of people died because they had no food．As an agronomy （农学） teacher．Yuan was very sad to see this． "How can I help them have enough food？" he thought．He decided to work on a kind of hybrid rice．It has a high output （产量）．
At that time， other scientists didn't think hybrid rice was worth studying． But Yuan and his team worked on it every day． They took very good care of their rice seeds．
At last， in 1973， they grew a new kind of hybrid rice． This rice is strong． Farmers can grow it in many different kinds of farmland and also in bad weather． It can also fight disease． Its output was much greater than common kinds of rice． With the new kind， about 70，000，000 people could have food every year!
Yuan solved the food problem in China．But he is still working on rice．Before he retires （退休），he hopes to grow rice in the sea!

As Internet users become more dependent on the Internet to store information，do people remember less？if you know your computer will store information，why do you store it in your own personal memory，your brain？Experts are wondering if the Internet is changing what we remember and how.
In a recent study，Professor Betsy Sparrow made some experiments（实验）.She and her research team wanted to know how the Internet is changing memory.
In the first experiment，they asked two groups of people to put 40 unimportant facts into a computer.The first group of people understood that the computer would store the information.The second group understood that the computer would not store it.Later，the second group remembered the information better.People in the first group knew they could find the information again，so they did not try to remember it.
In the second experiment，the researchers gave people facts to remember，and told them where to find the information on the Internet.The information was in an exact in an exact computer folder（文件夹）.Surprisingly，people later remember where the folder is better than the facts.When people use the Internet，they do not remember the information.However，they remember how to find it.This is called "transitive memory （交互记忆）".
According to Sparrow，we are not becoming people with poor memories as a result of the Internet.Instead，computer users are developing stronger transitive memories；that is，people are learning how to organize a lot of information so that they are able to get it at a later date.This doesn't mean we are becoming either more or less clever，but there is no doubt that the way we use memory is changing.

If your pencil box is broken，the batteries（电池）in your flashlights run out，or you have some leftover food，how will you deal with these things？You will probably throw them all into one rubbish bin.But actually，we need to sort（分类）all the rubbish separately.If you don't sort your rubbish，all of it will go to a special place where it is buried（埋藏）together.As a result，it will take up some fields.Some rubbish will pollute the groundwater.Some rubbish that can be reused will be wasted.
In recent years，some Chinese cities have been working hard on rubbish sorting.
Shanghai has called on all the people living in this city to sort their rubbish into four groups：wet，recyclable，harmful and dry.Wet waste is known as household waste.They are things you don't want but pigs can eat.Paper，metal，glass，plastic and other things that can be reused are recyclable waste.Harmful waste includes thins like medicine，batteries.Finally，any waste that is not wet，recyclable or harmful will go to the "dry waste" bin.
Many other Chinese cities are also using this way to sort their rubbish.For example，Deyang has been sorting its rubbish into the same four groups since several years ago.Students in Deyang have already received waste﹣sorting guidebooks.They have studied these books and known how to sort the rubbish.
China is now improving its waste﹣sorting efforts.There is still a long way to go.But it's never too late to learn how to sort your rubbish rightly.We should take an active part in it.

To become a better person，we should go to school every day.So how can we become powerful and start changes in our own life？Perhaps we can get some tips from the US First Lady Michelle Obama.During her visit to China，from March 20–26，Mrs.Obama shared her views on education with students.
The first lady encouraged Chinese students to aim high and get a good education.In Chengdu No.7 High School，she told students that having poor roots doesn't matter A long as you work hard.
Mrs.Obama said her family was not rich.Like many Chinese students，her parents had big dreams for her.She felt the weight of her parents' sacrifices （牺牲） on her shoulders and worked hard to make them proud.
Persevering was not easy，though.Sometimes she had to wake up at 4：30 a.m.and study late into the night. "But whenever I got tired or discouraged，I would remember something my mother always told me，" she said， "A good education is something that ①take，no，from，can，one，away，you."
Mrs.Obama also encourages Chinese students to study abroad. "As the Chinese B goes，
②It is better to travel 10，000 miles than to read 10，000 books，" she said. "③在学校取得好成绩是不够的。It's also important to have real experience with languages，cultures and societies different from your own， " she noted.
"Studying abroad could also gain future international relations. ④It could help young people from different country work together to deal with problems such as climate change，" Mrs.Obama said.
