1 . After decades of playing catch-up with the U.S. and Russian space programs, China did something neither nation nor any other had done this December: land a spaceship on the dark side of the moon.

Strictly speaking, of course, the moon has no dark side. But because of the way it orbits Earth, our natural satellite shows us only one side － the other is hidden from our view. No one even saw the far side until 1959, when the Soviet Luna 3 spaceship flew around for a look and sent back photos. No astronaut or spaceship went there until this December, when the China National Space Agency (CNSA) launched a 2,500-pound lander called Chang’e-4 to the southern end of the lunar far side.

Chang’e-4 operated a small rover (探测车) to survey the geography there for the first time ever. By examining the geography of its landing area, Chang’e-4 could solve longstanding puzzles about the moon, including how it formed 4.5 billion years ago. Chang’e-4 also carried a very small ―lunar biosphere (生态圈) ‖ containing silkworm eggs and a tiny greenhouse designed to grow potatoes in order to study the growth of the seeds on the moon.

Besides Chang’e-4, China plans to launch Chang’e-5 in 2019. Its mission will be to gather moon rocks using an orbiter, a lander or collector, an ascent stage (上升器) and a capsule that will separate from the orbiter and return the rocks to the earth. ―With these missions, the Chinese will have shown complete mastery of flight in the space between the earth and the moon,‖ said Paul Spudis, an experienced lunar researcher based in Houston.

CNSA has already outlined ideas for Chinese astronauts to follow the robots to the moon. Pei Zhaoyu, deputy director of CNSA’s Lunar Exploration and Space Program Center, told that China plans a permanent robotic lunar station in about 10 years and suggested a human presence on the moon another decade or so after that. Spudis said China’s ambitious Chang’e-4 and Chang’e-5 missions should send human’s plans for lunar return into rapid development.

2 . 阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

People are always buying things because they want to get the     1     (late) products. However, in the future people will probably buy fewer things because of     2     development of digital technology.

In the past, new inventions brought many products into our houses, but digital technology often     3     (replace) these things with a single device. For example, your mobile phone can now be your television, radio, music     4     (play) and alarm clock. In the future, children may play all their games on a phone or tablet, and so traditional board games will disappear. Consequently, people     5     (have) less stuff in their house, for they spend a lot on digital services.

Secondly, digital technology supports a     6     (share) economy, and that means people will not need to buy so many things. Owning a car will not be necessary as you will simply have an app     7     (book) a driverless car when you need one. People will share things     8     bicycles and gardening equipment within their local community by using an app to find what they need.

To sum up, digital technology will     9     (definite) continue to change our lives, and one of those changes will be     10     we won’t need to own so much stucco.

3 . Think of the empty cities in zombie(僵尸)movies. The streets, the shops and the schools still there just like they would be on a normal day, except there are no people to be seen. It is the emptiness that scares you.

Now a real-life "ghost city" is being built in the US. But fortunately, it has nothing to do with zombies - it is going to be a place to test the technology of the future

Called CITE - the Center for Innovation(创新), Testing and Evaluation(测评) - the city is the idea of technology company Pegasus Global Holdings. Covering an area of 15 square miles (39 square kilometers), it is the size of a small US city and sits in the middle of the New Mexico desert.

But why do we need an empty city that nobody will call home?

The reason is that we can't afford to test the latest technologies in the cities that we live in - they might not be ready and could cause problems and danger in our everyday lives.

"It will be a true laboratory without the problems and safety issues that come with people living there. Here you can break things and run into things, and get used to how they work, before taking them out into the market, Pegasus managing director Robert Brumley told technology magazine Wired.

In fact, without worrying about hurting people, anybody with a new idea can ask to test it in this city. Just think about the possibilities- driverless cars can move freely on the streets, homes with robots can be designed and energy sources like nuclear power can also be put to the test.

As good as the idea may seem, however, there are still doubts about CITE. "One of the most difficult things to do when developing these new technologies is to have them safely move around people, who can suddenly jump out in front of something," Reese Jones, a founder of Singularity University, US, told Fortune magazine.

Jones is worried that, even if a technology works perfectly well in CITE, introducing it to a real city will still be a whole different story because there will be people living in the city.

But no matter what, perhaps we should wait until CITE is finished in 2018. Maybe it will turn out to work just fine.

1. The empty city is being built_____.

A．so people can experience the technology of the future

B．to try driverless cars and robots in

D．Anyone can ask to try out their new designs there.

3. According to Jones,_______.

A．CITE offers great possibilities for future technology

B．new technologies will work perfectly well with the help of CITE

C．settings in CITE should be real in order to create the best results

D．testing results in CITE may not prove to work in a real city

4. What is the main purpose of this article?

A．To explain why CITE could be very helpful.

B．To show that CITE has a bright future.

C．To explain CITE and problems it may have.

D．To offer a good solution that will help to develop future technologies.

4 . British MPs (国会议员) have voted in favour of the creation of babies with DNA from two women and one man, in a historic move. The UK is now set to become the first country to introduce laws to allow the creation of babies from three people. In a free vote in the Commons, 382 MPs were in favour and 128 against the technique that stops genetic diseases being passed from mother to child. During the debate, ministers said the technique was “light at the end of a dark tunnel” for families.
A further vote is required in the House of Lords. If everything goes ahead then the first such baby could be born next year. Supporters said it was “good news for progressive medicine” but critics say they will continue to fight against the technique that they say raises too many ethical (伦理的) and safety concerns. Estimates suggest 150 three-person babies could be born each year.
Prime Minister David Cameron said: “We're not playing god here; we're just making sure that two parents who want a healthy baby can have one.” The method, which was developed in Newcastle, should help women like Sharon Bernadi, from Sunderland, who lost all seven of her children to mitochondrial (线粒体的) disease. Ms Bernadi said she was “overwhelmed” by the decision.
Mitochondria are the tiny compartments (隔间) inside nearly every cell of the body that transform food into useable energy. They have their own DNA, which does not affect characteristics such as appearance_____ mitochondria are passed down only from the mother. They can lead to brain damage, muscle wasting, heart failure and blindness. The technique uses a modified version to combine the DNA of the two parents with the healthy mitochondria of a donor woman. It results in babies with 0.1% of their DNA from the second woman and is a permanent change that would be passed down through the generations.
1. According to the passage, which of the following statements is NOT true?

A．The new technique is intended to provide the parents a healthy baby.

B．The mitochondrial disease can lead to various fatal illnesses.

C．Britain is the first country to have created three-person babies.

D．All of Ms Bernadi’s children died of a genetic disease.

2. The underlined word “defective” is closest to the meaning of ________.

A．strangely-made	B．normally developed
C．functioning perfectly	D．not functioning properly

3. It can be inferred from the passage that ________.

A．Mitochondria are inside nearly every cell that change food into useable energy

B．DNA of Mitochondria can affect a person’s appearance

C．in medical science ethical factors should be taken into consideration

D．the donor woman’s DNA will not be found in the three-person baby

4. Prime Minister David Cameron _________ the creation of such babies.

A．is in favour of	B．throws doubt on
C．objects to	D．is indifferent to
