Do you know Venus (金星)? Of the eight planets, Venus is the nearest one to us. Venus was the Roman goddess of love and beauty. In Greek her name was Aphrodite. Venus and the Earth are almost the same size, and you would weigh almost the same on both planets. If you were 70 pounds on Earth, you would be 63 pounds on Venus. Venus is an “unfriendly” planet. Because of its thick cloud, you can’t see the surface (表面). In many ways, Venus is like the Earth. It has active volcanoes (火山), mountains and valleys, too. But Venus is too hot for life. It has the highest temperature of the planets in our solar system, about 480°C. Besides, the Earth lets heat out through volcanoes, hot springs. But Venus lets heat out in a different way. Venus has no moons. Scientists call Venus the Earth’s sister planet because Venus and the Earth are almost the same size. For a long time, most scientists thought that Venus probably had plants, animals, and possibly even human beings. However, because Venus is so hot, it is impossible for anything to live there.

【推荐1】We have seen lots of science fiction movies about aliens. People travel to stars and even fight with aliens in the movies. But are there real aliens in the universe（宇宙）? Most of us think it is impossible, just like fairy tales. But the answer of some scientists is yes. So they have been searching for aliens in outer space for many years. They hope to find life signs of aliens.
Some scientists are used to using radio telescopes（望远镜）to search for aliens in space. In order to find aliens, they have worked hard for over half a century, but so far they have found nothing. Then some scientists guessed aliens might not want to connect us, but aliens could answer our messages. So some scientists sent radio signals into the universe. They hope one day they would be picked up by alien technology. These scientists want to prove（证明）that we are not alone in the universe.
But what should we do if the “alien phone” rings one day? Should we answer it? Stephen Hawking, the famous physicist, thought it could be dangerous to connect aliens. He said that the main purpose of aliens’ visiting to the earth could be searching for our resources（资源）. But other scientists think we have no need to worry. David Morrison, a NASA scientist, said, “If an alien radio signal reaches the earth from a planet thousands of light-years away, then they almost surely have solved all the problems we still have including the short of resources. Maybe they are much smarter than us, but why do they want to hurt us? I think we can try to connect them.”

【推荐2】If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet (彗星).
A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth, a comet goes round the sun, but on a much longer path (轨道) than the earth travels.
If a comet isn’t a star, what is it then?
Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.
Many people perhaps have seen a comet. However no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.
An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley because he was the one who worked out when it would come back again. Maybe you have ever seen Halley’s Comets because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s Comets when it comes near the earth again.
1. A comet is like ________, goes round the sun.| A．sun | B．star | C．planet | D．the earth |
| A．water and rock | B．water frozen into pieces of ice and mixed with iron |

【推荐3】From far out in space, Earth looks like a blue ball. Since water covers three-fourths of the Earth’s surface, blue is the color we see most. The continents（陆地）look brown, like small islands floating in the huge, blue sea. White clouds cover around the Earth like a light blanket（毯子）. The Earth is shaped like a sphere, or a ball. It is 25, 000 miles around! It would take more than a year to walk around the whole planet. A spaceship can fly around the widest part of the sphere in only 90 minutes.
Even though spaceships have traveled to the Moon, people cannot visit the Moon without special suits. The Moon has no air or water. Plants and animals can’t live there either. Astronauts first landed on the Moon in 1969. After that, there were six more trips to the Moon. They brought back Moon rocks, which scientists are still studying. There are holes, or craters（火山口）, all over the Moon’ s surface. Scientists believe that meteorites（陨石）smashed into the Moon millions of years ago and formed the craters.
The Sun is the closest star to Earth. A star is a hot ball of burning gas. The Sun looks very big because it is so close. But the Sun is just a medium-sized star. Billions of far-away stars are much bigger than our Sun. The burning gases from the Sun are so hot that they warm the Earth from 93 million miles away! Even though the Sun is always shining, the night here on Earth is dark. That's because the Earth rotates, or turns around, every 24 hours. During the day, the Earth faces the Sun. Then we see light. During the night, the Earth turns away from the Sun. Then it faces the darkness of space.
Each day we learn more about the Earth, the Moon and the Sun.

【推荐1】Do you know what music people like listening to? If you ask them, you may get many different answers. Why do different people have different musical preferences? What do these differences say about us?
Researchers from Cambridge University tried to answer these questions. They asked 350,000 people from 50 different countries. Then, they found that musical preferences depend on personality (性格). Outgoing people prefer danceable music with strong beats such as rap. Country music fans are shown to be more serious in their jobs. One of the findings is quite interesting. The researchers thought that people with much stress (压力) should like sad music or rhythmic (有节奏的) music. But it turned out that these people dislike these two kinds. Instead, they like loud music better. Maybe they like to listen to this kind of music to lower their stress.
The researchers also found that climates may affect people’s musical preferences and personalities, too. People in hot weather prefer danceable music. They are more outgoing. This may be a result of longer daylight hours. They advised people to go outdoors to dance.
Of course, nothing is clear-cut. We may not group people simply by their musical tastes. The study just showed us that people of different cultures are more similar than we think. “People are grouped by language and culture,” said Dr. David Greenberg. “But if an outgoing person in one place likes the same music as outgoing people in other places, then we can say that music is really like a bridge.”
1. How does the writer begin this topic?| A．By asking questions. | B．By telling stories. |

【推荐2】When we hear the word “virus”, we naturally think of something dangerous. However, some viruses coexist (共) with us and we can even make good use of some of them, according to recent studies.
Biologists suggest that 380 trillion viruses are living on and within your body right now. These viruses are collectively known as the human virome (病毒组). Some can cause illness, but many simply coexist with you.
It appears that our viromes begin to accumulate when we are born. Studies have shown different viruses in the babies’ bodies shortly after birth, suggesting that they probably come from the babies’ mothers. The viromes grow in number as the kids grow up. They are not likely to change during adulthood.
“The virome looks like a partner that can influence our daily lives positively as well as negatively. We could even use the virome to improve our own health,” said David Pride, an expert from the US.
One way is to use parts of viruses to cure diseases. Researchers in the US have got a chemical from a virus that kills bacteria (细菌) found in patients.
The other way is to develop viruses’ value. Many viruses in our viromes infect bacteria. When the viruses move around the body, some arrive at the surfaces of our bodies such as the nose, throat and stomach. Viruses cannot divide and produce exact copies of themselves there, but they can wait for a bacteria to arrive. This process makes it possible to prevent us from getting certain diseases.
1. What does the underlined word “accumulate” in paragraph 3 mean?| A．produce matters. | B．create problems. | C．increase the quantity. | D．examine the body. |
| A．Viruses even appear in the body of a baby. |
| B．Not all viruses cause illnesses in our body. |
| C．There are less than 380 trillion viruses in a baby’s body. |
| D．The number of viromes grows largely in the body of adults. |
| A．They help people avoid certain diseases. |
| B．They have a chemical that can cure cancer. |
| C．They can copy themselves to kill harmful bacteria. |
| D．They can turn harmful bacteria into a harmless one. |
| A．To describe how viruses come into being. |
| B．To explain how viruses can be very useful. |
| C．To show the importance of human viromes. |
| D．To introduce our relationship with viruses. |

【推荐3】Do you have any experiences like this? When the teacher asks if someone could speak in front of the class, you low your head. When you go to the restroom or dining hall, you always try to find someone to go with you because you are afraid of being seen alone.
Well, many people have these kinds of experiences. They are feeling social anxiety (焦虑), or worrying about things like talking, going to a party or being the center of attention. A recent survey from China Youth Daily showed that about 45 percent of the 1,544 interviewees (受访者) said they experienced social anxiety.
Stefan G. Hofmann, an expert from Boston University, the US said that social anxiety is “a result of the fear that we will not be welcome”. For Chinese kids, there’s another reason for their anxiety. Shu Man from East China Jiaotong University said, “Most of them are the only child in their families, so they don’t have many chances to practice their social skills.”
“However, you don’t have to worry about too much about social anxiety. You only need to get help from a doctor if you can’t live a normal life,” said Li Songwei from Tsinghua University. Shu Man advised that you should go to public places more often, and try thinking about something happy when you are really nervous.
1. How many people experience social anxiety in the recent survey?| A．About 45. | B．About 695. | C．About 1,544. | D．About 1,589. |

Which animals are smart? Your answer may be dogs, monkeys or elephants. Now there is one more animal that can be added to the list: sheep.
Scientists from Cambridge University said that sheep could be trained to identify human faces. Before testing, scientists let the sheep take a look at pictures of four famous people, including Barack Obama. Then the sheep went into a room with two computer screens. One screen showed a famous person. The sheep always walked toward the screen with the correct faces.
After discovering the sheep’s ability to recognize famous people, researchers gave them a new task. They wanted to see whether these farm animals could correctly identify the same people from different angles (角度). To their surprise, the sheep were still able to identify them, though they were a bit slower than before. Finally, the researchers wanted to know if the sheep could identify their trainers from a photo. As a result, the sheep could do this without any training.
The results show that the sheep’s face-recognition abilities are similar to those of monkeys and humans.
Face recognition is very difficult, but sheep have big brains. The researchers said it might be interesting in the future to find out whether sheep can identify different facial expressions made by humans.
1. According to the passage, sheep could ________ after being trained.| A．sing and dance to music | B．become smart like monkeys |
| C．look for farm animals | D．work on computer screens |
| A．识别 | B．模仿 | C．了解 | D．逃避 |

【推荐3】“Study trains” are rising in popularity in China
这辆慢车上，有间“开往春天的自习室”
When I am in the UK, I often have long train (火车) trips. I can do many things on these trips. I can read for the day’s lesson or read some interesting books on the way. Or I can do some homework on the way home (家). I can also write some beautiful words when I have a good time watching the views (景色). At that time, I always think, it must be cool if trains can be like libraries? Well now, in China, there are trains that do just that!
According to (根据) a CCTV News, a “study train” No.5609/5610 now goes between Chongqing and Xiushan County (县). It is a seven-hour trip and the price is only 54.5 yuan. On the train, workers put some desks and chairs by the windows to let people study when they travel. A slow (慢的) train that runs between Chengdu and Kumming is also like a “school library”. Students from nearby schools use their travel time to finish homework on the train.
In the UK, many students read or study in the library after school. But they also need to go home. So they can only be there for a short time. If we can learn (学习) from the Chinese and make the trains a place to study, I think every student will be happy.
It’s great that there are trains in China that have a good study atmosphere (氛围). Maybe, the UK can do the same thing.
1. If you take the train from Chongqing to Xiushan with your parents, you need to pay (花费) ________ yuan.| A．54.9 | B．109 | C．163.5 | D．218 |
| A．Only students can take (乘坐) the study trains. |
| B．The train from Chongqing to Xiushan runs seven hours. |
