Scientists have made the world’s first human-sheep----with the body of a sheep and half-human organs(器官). Amazing, but true. The sheep is15percent human and 85 percent sheep. The breakthrough(突破)makes it possible to use animal organs in human bodies in the future. Professor Esmail Zanjani of University of Nevada, US, has spent seven years And over $9 million on the work. Zanjani took stem cells(干细跑) from the human body and put them into the sheep while it was still in its mother’s body. The stem cells made other cells that grew into organs. Zanjani believe that in the future such sheep might be used to help humans. Two months later a human-sheep is born, it has a liver(肝脏), heart, ling(肺) and brain that are part-human. These organs could be used to help people in need of them. There are different opinions about his work, however. Some say that scientists don’t have the right to create new creature(生物). Using animal organ might bring animal viruses(病毒) into human bodies. Others are afraid that the work might change sheep. But Professor Anjani has said that this is impossible.

Scientists have discovered the first Earth-sized planet. It was first marked by scientists’ using NASA’s Kepler telescope(望远镜), so it’s called Kepler-186f. It lies about 500 light years from Earth and goes around its star. The planet is the right distance from its star for water: not too close or not too far. Water is one important condition that scientists guess is necessary for life. So it could have water and possible life. It’s called a true Earth cousin.
“This planet is an Earth cousin, not an Earth twin, ”said Barclay, who is among a team of scientists reporting on the discovery in the magazine Science this week.
“It’s very exciting to find a planet similar to the Earth, ”Barclay said. “It’s not easy work because things change as we get more measurements.”
Scientists don’t know anything about the air of Kepler-186f, but it will be a task for future telescopes which can study for chemicals that have something to do with life.
“It’s possible for life to live in this planet, but that doesn’t mean there is life in it,”Barclay said.
So far, scientists have found nearly 1, 800 planets in the universe.
“The past year has seen a lot of progress in the search for Earth-like planets. Kepler-186f is very important because it is the first planet that is the same temperature and is almost the same size as Earth, ”scientist David Charbonneau wrote in an email.
1.Scientists have already found about planets now
A. 500 B. 186 C. 1,800
2.The planet is the distance from its star for water: not too close or not too far.
A. far B. right C. close
3.Which of the following about Kepler-186f is NOT true according to the passage?

About 800 years ago, a Chinese man named Wang Hu made the world's first rocket, but unluckily he lost his life with it. It was not until April 24, 1970 that China sent its first satellite Dongfanghong-1to space successfully.
To celebrate the first big success for the country's space development, April 24 is now China's Space Day, which started this year. While celebrating, China also announced(宣布)new plans to make a space station and go to Mars and further space.
A space station is like a home for astronauts in space. Astronauts live and work on a space station and spaceships can even park there. China plans to finish building its space station in 2022.
According to China’s top space scientist Zhou Jianping, by that time, becoming an astronaut will be a normal job. Astronauts are needed more than ever before. They need to be able to finish more tasks. So far, China has been choosing astronauts mainly from pilots. In the future astronauts will also be picked from engineers, doctors and space technology experts.
Another plan is about Mars. In order to search Mars, China will send a probe(探测器)first to Mars around 2020. It will land there and even bring back things from the Mars.
It's such a big plan! Only by doing this can China say it has truly started the exploration of deep space. And the exploration will help us understand how the universe changes.

九年级英语填空困难题查看答案及解析
We have found plastic in the ocean and in animals. But for the first time, scientists have found plastic in human poop(粪便),USA Today reported.
The findings came from a study by scientists from Environment Agency Austria. The researchers followed eight healthy volunteers from different parts of the world. The volunteers wrote down what they ate for a week and then provided a stool sample(大便样本)for testing.
Scientists found nine different types of plastic particles( 颗粒)in the samples. “The smallest plastic particles are able to enter the bloodstream, the lymphatic system (淋巴系统),and may even reach the liver(肝脏)”said Philipp Schwabl, who took part in the research.
However, the scientists aren't sure if this plastic is harmful to humans. They're not sure how the plastic got into the volunteers' bodies, either. But most of the volunteers said they drank from plastic bottles and also ate seafood that could include plastic from ocean pollution.
In fact, plastic is everywhere around us. Every year, about 8 million tons of plastic waste goes into the oceans. There, sunlight and waves break the plastic down to small particles. Most of the particles stay in the ocean. Others can spread into the soil and air. Could plastic in the air fall onto food and get into the human body?
According to USA Today, 90 percent of sea salt sold in the world includes plastic. And even some top water has been found to have plastic particles in it.
1.According to USA Today, what have scientists found for the first time?
A.Plastic in the ocean. B.Plastic in animals.
C.Plastic in human poop. D.Plastic in the soil.
2.The researchers________according to the second paragraph.
A.followed eight healthy volunteers. B.are from Environment Agency Australia
C.wrote down what they ate for a week D.provided a stool sample for testing
3.Paragraph 3 is written to tell us that________
A.plastic particles can be a few different sizes B.plastic particles can reach many parts of our bodies
C.plastic can harm the lymphatic system D.plastic particles are inside all of us
4.What can we infer (推断) from the study?
A.Plastic does no harm to our bodies.
B.The best way to deal with plastic waste is to burn it.
C.People should stop drinking tap(水龙头)water.
D.It can be hard to avoid plastic in food and drinks.

Stephen Hawking, one of the world's most famous scientists, believed that humans will one day have to move into space, "Once we step into space, our future should be safe," he said.
Today, many countries are all planning to send astronauts to Earth's closest neighbor: the moon. Some of these countries want to create space stations there within the next 10 years. These stations will prepare humans to visit and later live on Mars or other earthlike planets.
__①__ Robert Zubrin, a rocket scientist, thinks humans should colonize(殖民) space. He wants to start with Mars. Why? He thinks sending people to Mars will allow us to learn a lot of things—for example, the ability of humans to live in a very different environment. Besides, any progress we make in the fields of science, technology, medicine. and health will do good to people here on Earth.
__②__ Elon Musk, the CEO of Space X also believes we should colonize Mars. His long-term goal is to put one million people there if something bad happens to us here on Earth.
__③__ Many people say it's too expensive. Also, most space trips are not short. A one-way trip to Mars, for example, would take at least six months. People traveling this kind of distance could face many health problems. Besides, these first people would find life especially difficult in space. On the moon's surface, for example, the sun's rays are very dangerous. People would have to stay indoors most of the time.

The United Nations has made the first Monday of October as World Habitat Day(世界住房日). The idea is to show the living level of ourselves. Everybody wants to have enough room. It also reminds the world of its duty for humans to have better habitat in the future.
We must improve city planning to deal with new challenges of the 21st century. In both developed and developing countries, cities and towns are feeling the effects of weather change, food danger, population growth and so on. These facts will change towns and cities in the century ahead. Many developing countries will continue to experience fast population growth in cities, along with its most serious problems, such as overcrowding and poverty(贫穷). Over half of the world’s population mainly live in cities, so there is no doubt that city planning will become the first thing to do for governments.
Unfortunately, the city planning systems in many parts of the world can’t deal with these challenges. After all, we know the problems, so we need to share the best solutions as efficiently and widely as possible by planning better for ourselves and our environment.

Scientists in Britain and the United States have made a new kind of enzyme(酵素) that eats plastics(塑 料). With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution.
The enzyme is able to break down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics.
The researchers made the discovery(发 现) while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids(氨 基 酸). It made the natural enzyme’s plastic-eating abilities work faster and better.
John McGeehan, one of the lead researchers, said, “We’ve made an improved enzyme. It’s better than the natural one. And we are trying to make more improvements to it.” He went on, “The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we are considering putting it into wider use.”
The team is now trying to make the enzyme break down PET in large quantities(大量). “We’ll see that the plastic pollution may be stopped with this technology. However, there is still a long way to go,” John McGeehan added.
1.Which is not true about the advantage of enzyme?
A.It’s able to make plastics become smaller parts.
B.It can solve the problem of the plastic pollution right now.
C.It’s used to make the plastics disappear in a rapid way.
2.The underlined phrase “break down” in the passage probably means “________” in Chinese.
A.实验 B.生产 C.分解
3.Which isn't the change they made to the natural enzyme?
A.Some amino acids were put in it.
B.The speed of plastic-eating has been improved.
C.The quality of plastic -eating remained the same.
4.Which of the following is TRUE according to the passage?
A.The scientists are still trying to improve the enzyme.
B.The enzyme will pollute large areas of land and water.
C.The natural enzyme woks better than the improved one.
5.We can’t infer from the study that________.
A.The team is able to increase the speed of the plastic -eating abilities
B.Efforts are made to increase the number of PET that the enzyme breaks down
C.Few efforts are required to the improvement of this new enzyme
