Summer is finally here for most of us． Sadly， summer is not so pleasant to people in a bit less lucky places， where air conditioning（空调） is not easy to get for most of them．
But as a saying goes， where there is a will， there is a way， especially for those who like doing it
yourself（DIY）． A young man from Bangladesh（孟加拉国） designed an air conditioning system called the Eco Cooler， one that does not require power， and is made of the world's most common waste﹣plastic bottles．
The Eco Cooler is super simple to build﹣no special engineering skills are required． First， to fix it，
a window should be taken away and replaced（替代） by it． Second， a board should be cut into the size of a window． Some bottle﹣neck sized holes should then be cut onto the board． Then， the funnel﹣shaped（漏斗状） bottlenecks， cut from the plastic bottles， should be put into the holes．The next step is to fix the design onto the window frame（框） with the wider side facing outwards． And this is it．
The Eco Cooler then works by catching the winds and sending them inside the building． It can reduce the temperature of a room by as much as 5°C﹣a big difference when looking at comfortable 25°C compared to uncomfortable 30°C．
The idea of the inventor， Ashis Paul， was to show his great product to as many People as possible． For this purpose， he received help from some groups of volunteers． Together， they offered to help local people build and fix the units，as well as teach them how to make them themselves．
Yes， the Eco Cooler is not a super high﹣tech air conditioning system， but it is one that can make a
big difference．
（1）When building the Eco Cooler， we should pay special attention to ．
A． the shape of the window

Some people seem to have unusual memories． Zheng Aiqiang， a "memory athlete" on TV show Super Brain， can remember 2， 660 numbers in just one hour!
You would think people like him must have special brains． But according to a recent study by researchers from America and Holland， the brain structure （结构） of ordinary people and 23 of the world's lending memory athletes shows no difference．
Good memories can be trained． New research in the magazine Neuron suggests that a person will get a super memory with just six weeks of hard training．
Researchers found that a technique （技巧） called loci， invented by the ancient Greeks， can greatly help improve memory．
By using loci， you are using your imagination to improve the brain's memory networks． You can link （关联） something you need to remember with a place that you know very well． For example， to remember a list of numbers， imagine yourself walking through your house． Each thing is linked to a number． For example， zero could be the handle on the door and five could be the painting on the wall．
In one study， some ordinary people were given 20 minutes to remember 72 nouns． At the beginning， they could only remember 26 words， but when they were taught loci， they could remember 62 words．
"Not everyone can become a memory winner． But everyone using the technique can improve his memory greatly，" said Boris Konrad， one of the researchers in the study．
（1）From the recent study， we know that ordinary people and memory athletes have similar ．
（2）To memorize a list of numbers by using loci means you are using your to link it with a you know well according to the passage．

What time does your school start？Do you wish you could get up later every morning？You are not alone if your answer is "Yes." In the US，many middle school students have the same wish.
In America，many schools start before 7：30 am.But that may change soon.A new law has been passed in California.According to the law，middle schools should not start before 8：00 am.The government hopes school children will have longer time in bed.
Many scientific studies show that teenagers are more active in the afternoon and in the evening.Simply telling them to go to bed earlier doesn't work well.Most of them don't get enough sleep because of bad sleeping habits and early school starting time.They need more sleep in the morning.Scientists suggest middle schools should start at 8：00 am.or later.Students can get well ready to learn and they won't fall asleep in class.______The change can help improve students' grades.
While scientists are happy with the new law，many parents disagree with it.They won't be able to send their children to school before they go to work.They also fear that later school starting time will lead to later ending time.As a result，their children will have less time to take part in after﹣school activities.

Rice is one of the most commonly eaten basic foods around the world.Buying it and cooking it is a daily matter.Yet for many，its presence has been a matter of life and death.It is a main food because it is easy to grow，besides low cost and convenience.A poor community in the developing world may find it difficult to bring in foreign fruits or raise cattle for meat，but it can almost certainly use the land it has in order to grow plenty of rice.
This was the great achievement of Yuan Longping，who passed away on May 22 this year.A great Chinese scientist，Yuan successfully developed what is known as "hybrid rice" which can produce up a 30% higher output.Yuan Longping was born in the year 1930，a time when China was very different.It was a nation，without modern industry，depending on the rice which they grew.The first few decades （十年） of his life were met with major social events，and a rapidly growing population that made food supply not last all the time.This experience left its mark on Yuan Longping，which made him focus on （关注） farming science and work on his research of hybrid rice.
His achievement would see the rice supply in China increasing from 56.9 million tons in 1950 to 194.7 million tons by 2017.By 1991，20% of the world's rice output came from hybrid rice，even if only being planted in 10% of fields.
Always remember，human development begins first with the most basic and sample things，such as developing rice.We should be thankful for scientific thinkers like Yuan.
（1）Why is rice a main food around the world？
（2）What did Yuan develop successfully？
（3）When was Yuan Longping born？
（4）What made Yuan focus on farming science？
（5）How many tons was the rice supply in China by 2017？

There are plenty of myths（神话） to explain how the world came to have a moon to bring light to the night time． But now there is a plan for a man﹣made moon． It will give us much more light than the natural Moon．
China is preparing to put a man﹣made moon in the sky above Chengdu by the end of 2020．It will reflect sunlight back onto the Earth． If it succeeds， three more such objects will be sent out in 2022，according to Wu Chunfeng， a space scientist． Wu said it would be similar to how we get moonlight， but he predicted（预言） that the man﹣made moon would have eight times the brightness of the real one．
This is because the object will be about 500 kilometers above the Earth． That will make it much closer to us than the moon， which is over 380 ，000 kilometers away，Wu added．
If the plan works， the man﹣made moon will save a lot of power．Scientist predicted that Chengdu could save around 1.2 billion yuan in electricity every year if a new moon lit up 50 square kilometers of the city．And in 2022 ， four man﹣made moons can take turns reflecting sunlight as they will not always be in the best position relative to the Sun． Together， they can give light to an area of up to 6 ，400 square kilometers on the Earth for 24 hours．That means its brightness will be seen in most areas in China，so reducing the need for streetlights．

"I spent my whole life doing one thing，" Gu Fangzhou once said.Known as "the father of sugar pills （糖丸）"，Gu passed away on January 2，2019.Eight months later，he received a national honorary﹣title （荣誉称号） "the People's Scientist" for his polio （脊髓灰质炎） research.
Gu Fangzhou，a famous medical scientist，was born in June，1926.Gu's family faced a difficult time with the sudden death of his father.He studied hard and finally entered Peking University as a medical student in 1944.After graduation，Gu made the decision to work to help improve public health.
In 1955，polio broke out in Nantong，Jiangsu Province.It paralyzed （使瘫痪） 1，680 people，mostly children aged below seven.It spread to neighboring areas and resulted in 466 deaths.Gu was asked to lead polio research in 1957. "At that time the only way to prevent polio was to invent a vaccine （疫苗），" said Gu.
In 1959 Gu succeeded in developing the first polio live vaccine.Later，he developed the "sugar﹣coated pill" vaccine in the early 1960s.It not only tasted better but was more affordable and easier to keep.To test the vaccine，Gu tried the vaccine in person and later his one﹣month﹣old son was vaccinated.This inspired his team to vaccinate their kids.They became the first group of people in China to try a polio vaccine. "If we don't believe in what we produce，how can others believe in it？" said Gu.
Gradually，the sugar﹣coated polio vaccine was made available in China.It saved millions of people，especially kids，from being disabled.In 2000，the World Health Organization （WHO） announced that China was already a polio﹣free country. "We feel satisfied.I can tell people that I tried my best，and your kids will no longer get polio，" said Gu. "That's all we hoped for. "
