Do stars only appear at night? The answer is no. Venus (金星) is the only star that can be seen in daytime. It shone at its brightest in the night sky on Feb 17 this year.

Venus is the second planet from the sun. It is the second brightest natural object, behind the earth’s moon, in the night sky. Why is it so bright?

First of all, Venus is the closest planet to the earth. It is also covered by highly reflective (反射的) clouds, which can reflect about 70 percent of the sunlight striking (照射) it, almost twice as much as the earth does. Some people call 2017 the year of Venus, because the planet is at its brightest twice this year. Venus gets brighter when it goes further away from the sun, and nearer to the earth. The brightest moment happened once in February, and will happen again, during daylight, on April 30.

If Venus is so bright and close to us, isn’t it a better choice for human exploration (探索) than Mars? It is closer to the earth than Mars and it’s closer to the earth in size. The closer distance to the sun means solar power (太阳能) would be easier to generate as well.

However, with a temperature of about 465℃ on the surface, Venus is the hottest planet in our solar system!

But scientists never give up. Recently, a team of NASA and Russian scientists created new computer equipment that can stand temperatures of 480℃. It can work under Venus-like conditions (环境) for almost 22 days.

The next step, according to the scientists, is to send a probe (探测器) to Venus by 2025.

1. Which of the following about Venus is NOT true?
A.It’s the only star that can be seen in daylight.B.It’s the second planet from the sun.
C.It’s the brightest natural object in the night sky.D.It’s the closest planet to the earth.
2. The underlined word “generate” is similar in meaning to the word “________”.
A.heatB.produceC.spreadD.form
3. What makes Venus a worse place for human exploration than Mars?
A.The closer distance to the earth.B.The similar size to the earth.
C.Too much solar power to use.D.The extremely high temperature.
4. According to the last two paragraphs, the new computer equipment ________.
a. was created by some UK scientists     b. can stand temperatures of 480℃
c. can work for about 22 days on Venus     d. will be sent to Venus by 2025

【推荐1】Is there intelligent(有智力的)life on other planets? For years, scientists said “no,” or “we don’t know.” But today this is changing. Seth Shostak and Alexandra Barnett are astronomers(天文学家). They believe intelligent life exists(存在)somewhere in the universe. They also think we will soon contact these beings(人;生物).

Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is size—the universe is huge. “Tools like the Hubble Telescope(哈勃望远镜)have shown that there are more than 100 billion galaxies,” says Shostak. “And our galaxy, the Milky Way, has more than 100 billion stars. Some planets going around these stars might be similar to Earth.”

In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes(高倍望远镜)allow scientists to discover smaller planets—the size of Mars or Earth—in other solar systems. These planets might have intelligent life.

Have beings from space already visited Earth? “Probably not,” says Shostak. “It’s a long way away.However, intelligent beings may contact us in other ways, such as radio signals(信号). In fact, they may be trying to communicate with us now, but we don’t have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other.”

1. Seth Shostak and Alexandra Barnett are ________.
A.astronomersB.farmersC.singersD.drivers
2. What is the best title for Paragraph 2?
A.The Age and Size of Earth
B.Our Galaxy: The Milky Way
C.Why Intelligent Life Might Exist
D.Earth: The Only Planet with Intelligent Life
3. Why was it hard to look for signs of intelligent life in the universe in the past?
A.There were not any smaller planets.
B.There were not any powerful telescopes.
C.The astronomers were not interested in them.
D.The Milky Way didn’t exist at that time.
4. Why haven’t beings from space visited us yet according to Shostak?
A.They’re afraid of us.B.It’s a long way away.
C.They don’t want to see us.D.They don’t know how to use radio signals.
5. What does the underlined phrase “life forms” in the last paragraph mean?
A.Messages.B.Tools.C.Intelligent beings.D.Radio signals.

文章大意:本文介绍中国在探测月球上取得的成就。

【推荐2】Like many other countries around the world, China hopes to explore the moon. It has already done so with several probes (探测器) and lunar rover (月球车). But it has even bigger plans to put a man on the moon in the near future.

Yang Liwei, China’s first man in space, said that it will “not take long” for a manned mission (任务) to get official agreement and money support, according to the Xinhua News Agency.

China’s space program is still young compared to those of the United States and Russia. But it has already made great achievements in exploring the moon. Its moon mission began with Chang’e 1, an unmanned orbital (轨道) probe that was sent up in October, 2007. It collected data that was used to create a 3-D map of the moon’s surface.

China achieved another achievement with the Chang’e 3 mission. For this mission, China’s first lunar rover, Yutu, successfully landed on the moon.

For China’s space program, it was another great achievement that Chang’e 4, the second lunar rover successfully landed on the moon’s far side, an area that has not yet been explored, in December, 2018.

China will follow Chang’e 4 with a series of other lunar mission. These missions will include taking lunar soil and rock samples, building “moon base”, and hopefully landing a human on the moon’s surface around 2030, according to Zhao Xiaojin, a senior official at the China Academy of Space Technology.

Last year, when Yang Liwei was asked if he had any plans to visit the moon himself, he replied, “If I am given the chance, no problem!” It is likely that many other Chinese share Yang’s excitement about this new stage of China’s space exploration efforts.

1. Which of the following countries may be better than China in space program?
A.Russia.B.The UK.C.Canada.
2. China has already made great achievements in exploring the moon, such as, Chang’e 1 was ________.
A.the first lunar rover and landed on the moon
B.the second lunar rover and landed the moon’s far side
C.an unmanned orbital probe and began the moon mission
3. From this passage, we can know that Yang Liwei ________.
A.is China’s first man on the moon
B.is worried about China’s future space program
C.believes it won’t take long to put a man on the moon for China
4. What`s the best title for this passage?
A.Hope for FutureB.China for SpaceC.A Moon Base

【推荐3】The solar system has eight planets. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The Planets are all round, like balls. The planets all go around the sun.
Mercury is the closest to the sun. It is very hot on Mercury. The planets that are far away from the sun are very cold. Venus is between Mercury and the Earth. It is sometimes called Earth’s “sister planet” because they have almost the same size and shape. The Earth is the planet where we live. From space, the Earth looks blue because it has so much water. Jupiter is the largest planet in our solar system. Saturn is known for having rings around it. Uranus was the first planet discovered with a telescope. We can see Venus, Mars, Jupiter, and Saturn with our eyes, however, to see Uranus, we need a telescope. Neptune is the 8th planet in our solar system. The planet is farthest from the sun.
Probes (探测仪) go into space and take pictures of the planets. We learn a lot from these pictures. If you could send a probe to any planet, where would you send it?
