【推荐2】Sophia is an intelligent human-like robot, and famous for being the     1    (one) robot to be awarded citizenship of a country, Saudi Arabi A. But     2     is unclear whether she will receive the same rights as human citizens.

It was born with a perfect combination of science and art. Scientists said her face     3     (design) beautifully, like a pretty actress, Audrey Hepburn. The robot has the ability     4     (show) more than sixty-two facial expressions. What’s

As     9    result, some scientists have a prediction.     10     production and development of AI were not able to be controlled, this could be a deadly risk to the existence of human beings in the future.

China reached a milestone in space exploration on January 3, 2019. Chang’e-4     1     (successful) landed on the far side of the moon’s surface.

This is the first time in history     2     any country has performed a soft landing on the back of the moon. It is also a huge win for Chinese scientists who have been planning out this work for       3     (year).

Shortly after the lander’s arrival, it sent back a photo of the Yutu rover (月球车)     4     (roll) slowly across the moon’s dusty surface. As     5     (expect), the lander will conduct a number of challenging tasks. It will observe the low-gravity environment and explore     6     there is water or other resources. Later, soil samples     7     (collect) and returned to the earth. Scientists believe that the back of the moon is     8     (ancient) than the front, so the soil age is valuable for studying the early history of the moon.

Since the far side of the moon is quiet and free     9     electromagnetic interference (干扰) from the earth, it’s a perfect place to research the space environment. Everything     10     (appear)   to be working smoothly, and we can expect plenty of moon news out of China in the near future.

【推荐1】Can you imagine waking up each day in a house that is     1     (gentle) rocked by the movement of water? Well, for some people this vision of the future may become a reality.

It is a commonly accepted fact that       2     the Earth’s temperature rises, the ice caps at the North and South Poles will melt,     3     (cause) the sea level to rise.

So, where does this leave the many countries in the world       4    have large sections of their populations living in areas which lie at or below sea level? The Netherlands, for example, is one of       5     most highly populated, low-lying countries and       6     (battle) with the problem of flooding for years. Further rises in the sea level would result in much of the country disappearing under water.

Inventive architects may have come up with a       7     (solve) to the problem: a house actually built on the water. The basic idea is that houses will have a base       8     (fill) with air and a way of anchoring(使固定) them to the ground. This will allow the house       9     (move) upwards whenever the sea level rises and sink back down when the sea level drops. So, will       10     (float) houses be the homes of the future? For some people there may be no alternative.

Cards and digital(数字的) technologies     1    (kill) off cash slowly, but is it a cause for concern? Not     2    (necessary). Here are some ways of making the most of digital finance.

Cash is no longer king. Over recent years fewer and fewer transactions have been made with cash. The most recent figures show coins and notes are used just 34% of     3     time, down from 63% a decade ago. And usage     4    (predict) to fall to just 10% in 15 years.

Instead we’re paying with cards and digital technologies. Some of this is down to user choice, with contactless cards and smartphones making spending     5    (fast) and more convenient.

But it’s also being forced upon us. Some retailers are refusing physical money as they can avoid the high bank charges levied(征收) at them for     6    (handle) cash. Meanwhile it’s harder to get your hands on notes as cash machines and     7    (bank) disappear from the high street. And these are trends which are likely     8    (increase) in the coming years.

This could be bad news if you still primarily use cash,     9     that’s how you pay your bills or how you budget. For some, cash is just what you know. For     10    , cash is a necessity—especially when going digital is the alternative.

As a result this move towards cashless society makes many uneasy.
