On Dec 22, China became the third country in the world after Japan and the US to have a carbon dioxide(CO2)monitoring satellite.
Named Tansat, as "tan" is the Chinese word for carbon, the satellite moves around Earth at about 700 kilometers above the ground. There, it can “see” clearly how much CO2 there is in the air and how it is moving.
How is TanSat able to do that?When sunlight travels through the air, the CO2 molecules(分子)take in different colors from the light. The satellite then looks at these colors to find out how much CO2 there is in the air.
“The TanSat has very good vision(视力), and it can tell changes in CO2 as small as 1 percent, ” said Yin Zeng shan, one of the satellite's designers at the Chinese Academy of Sciences, according to Xinhua News Agency.
But there is a question. When CO2 can already be measured from ground stations, why do we need a satellite that does the same thing?
The truth is that they don't do exactly the same thing. According to Zhang Peng, vice director of the National Satellite Meteorological Center, the data from ground stations is limited and it does not cover the ocean area, which takes up more than 70 petcent of Earth's surface.
But TanSat has solved the problem. It has a bird's eye view of the Earth, covering both the land and the ocean. It can also change its mode(模式)and position when looking at the ocean area because the water can reflect light. This light may change the data if its normal mode is used.
More importantly, China is now working on its goal of producing less CO, , starting from 2030 or earlier. To meet that goal, it will need to keep track of every bit of progress that it's making.
And with TauSat, China will have first-hand, detailed data of CO2 emissions in different areas, provinces and parts of the ocean, no longer having to use data from Japan and the US.
1.Which of the following about TanSat is TRUE?
A.It collects the CO2 in different areas above the ground.
B.It gets CO2 data by studying the colors of air.
C.It has been developed with the help of Japan and the US.
D.It has different modes to suit different weather conditions.
2.By reporting that the TanSat has very good "vision", the article shows that_______________.
A.the satellite uses many different kinds of cameras.
B.the satellite is very sensitive.
C.the satellite can capture every change in CO2.
D.the satellite can reflect light at 700 kilometers above the ground.
3.What can be concluded from the last paragraph?
A.TanSat is specially designed to reduce China's CO2 emissions.
B.China did not have any detailed data of CO2 emissions before.
C.TanSat will play a key role in helping to reduce China's CO2 emissions.
D.China is going to share its data of CO2 emissions with other countries.
4.What could be the best title for the passage?
A.Making great achievements B.Cutting CO2 emissions
C.Monitoring the ocean D.Checking more carbon

On January 13, 2016, France became the first country in the world to pass a law requiring supermarkets to donate food that is approaching its expiration date (保质期) instead of throwing it away. The regulation that applies to supermarkets over 4,000 square feet requires stores to sign official donation agreements with local food banks.
The law also makes it illegal for stores to pour water over nearly-expired food, or store it inside locked warehouses until it is picked up by the garbage trucks. These measures are often undertaken by supermarkets to prevent the hungry from searching for food through the dustbins.
Though that may appear cruel, the stores claim they do it to avoid potential food poisoning that could occur if the product is on its way past its expiry. Those who do not obey the new law face the risk of heavy fines.
Also, excess goods like yogurt or milk that are likely to go bad quickly are now allowed to be donated directly to the food banks. Though this has always been possible, the current process is long and complex, making it difficult for producers to give away the food in a timely manner.
France’s food banks are of course thrilled about the possibility of receiving extra food. Jacques Bailet, who heads a network of French food banks called the Banques Alimentaires, says that of the 110,000 tons of goods received annually, only 36,000 tons comes from supermarkets. Bailet estimates (估计) that just a 15% increase in supermarket donations would translate to over 10 million additional meals to feed the hungry each year.
Though this is a great first step, Arash Dermabarsh, the activist responsible for the grassroots movement that led to the ban, is not done. He now wants to extend the law to other places like restaurants and also try to convince other countries in the European Union to pass similar regulations. These steps are necessary because of the over 9 million tons of food wasted in France; an astonishing 67% is thrown away by consumers, with supermarkets and restaurants making up the rest.
1.What should stores do with nearly-expired food?
A. Throw it away. B. Send it to the hungry.
C. Store it in refrigerators. D. Give it away to food banks.
2.What does the underlined word “excess” in Paragraph 4 probably mean?
A. Extra. B. Cheap.
C. Seasonal. D. Returned.
3.What might Bailet agree with about the French food banks?
A. They have a lot of expired food.
B. They will get much benefit from the law.
C. Their food is enough for the people in need.
D. Their food mainly comes from supermarkets.
4.What does Dermabarsh plan to do?
A. Build more food banks in France.
B. Make the law take effect in more places.
C. Organize a campaign to promote this law.
D. Raise consumers awareness of waste reduction.

China became the first country to clone a monkey using non-reproductive cells, scientists said on Thursday. By December 2017 , the Chinese Academy of Sciences had created two clone macaques(猕猴) named“Zhong Zhong” and “Hua Hua”by nuclear transferring of body cells—any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.
Telra, a monkey born in 1999 , is the world’s first ever-cloned monkey, but it was done using a simpler method called embryo splitting(胚胎分裂),and cannot be genetically modified to suit experimental needs, said Pu Muming, a leading researcher at the Chinese Academy of Sciences. Cloning a monkey using body cells has been a world-class challenge because it is a primate(灵长类)that shares its genetic makeup, therefore all of its complexity, with humans, he said.
For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes, Pu said.
By cloning monkey using body cells, we can mass reproduce a large number of genetically identical monkeys in a short amount of time, and we can even change their genes to suit our needs, he added. “This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.”
Sun Qiang, director of the non-human primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different.
Monkeys and humans are both primates, so they are much closely related and testing on monkeys is supposed to be as effective as testing on humans. This achievement will help China lead the world research in an international science project related to study of primate brains.
1.Which description of the two clone macaques is true?
A. They were the first monkeys ever-cloned in the world.
B. They were created using reproductive cells.
C. They would be fed to suit experimental needs.
D. The technology used to create them was similar to that of creating Dolly.
2.The underlined word in the fourth paragraph is closest to “ ”in meaning.
A. same
B. similar
C. relevant
D. close
3.What can be learned from the passage?
A. Pu Muming and Sun Qiang were doing most work in cloning the two macaques.
B. Genetic research on monkeys can be seen as effective as that on humans.
C. Most drug trials have been done on mice because mice share the same genetic makeup and complexity with humans.
D. Scientists can mass reproduce cloned monkeys to cut down experiment costs.
4.This passage above can be most probably read in
A. a science magazine
B. a guidebook
C. a science fiction
D. a brochure

Dec.11 marked the 15th anniversary of China's entry into the World Trade Organization (WTO). On that day in 2001, China formally became a member of the WTO. Now the country has grown into the world’s second-largest economy and the largest trading country, while millions of Chinese have been lifted out of poverty. And 15 years on, it’s evident that being a WTO member has transformed the nation’s everyday lives for the better.
Imports are now a common sight in Chinese stores and supermarkets, while they were previously rarely seen on shelves. The Chinese now have access to many imports varying from luxury goods like high-end cars and famous brand watches, to daily necessities. China’s WTO membership has also made imports less expensive for the Chinese public.
For instance, since 2005, no tariffs (关税) have been imposed (施加) on Chinese imports of digital cameras and other devices.
Our education industry has also benefited from China’s WTO membership. Many top global universities have joined forces with Chinese ones to establish cooperative education institutions, bringing foreign teaching concepts to Chinese students. For example, New York University Shanghai was jointly founded by New York University and East China Normal University. In addition, an increasing number of Chinese students are furthering their studies abroad, while many foreign students are coming to China to carry out their higher education. According to the Ministry of Education, 523,700 students studied overseas last year, and the number is expected to keep growing this year.
