1 . At first glance, SoFi looks exactly like a real fish. But if you look     1    (close), it’s not hard to spot the truth: SoFi is a robot, or as     2     (it)MIT developers call it, “ a soft robotic fish”, according to BBC news.

SoFi     3     swim, turn and change speeds just like a real fish, and more     4     (importance), it can take high-resolution photos and videos with a camera     5    (build) into its nose. The robot’s “ soft artificial muscle” is made of a type of rubber, it has two side fins(鳍)for waving,     6     its nose also hides important electrical components(组成部分).

The team at MIT developed SoFi to swim among real fish to explore where few other robots or humans can, reported the Los Angeles Times. It     7    (operate) with a waterproof video game controller by someone     8     can be up to 21 meters away.

According to its leading     9    (create) Robert Katzschmann, SoFi, pronounced like the girl’s name “Sophie”, is an abbreviation(缩写)of soft fish--- and was named     10       a girl he had a crush(暗恋)on in high school.

During the last Spring Festival, I get lots of money by snatching(抢)the red envelope through WeChat. But now I am losing in thought --- whether it really does good to people, especial young   children, since the smartphone is now so popular. From his point of view, it will do more harms than good to young children unless they are addicted to snatching the red envelope. On the one hand, they will think it’s such easy to get much money. Just by snatching they can get it. On other hand, spending too much time on the things that they have nothing to do with their studies will never benefit them. It’s bad for either young people’s mental health but physical health.

3 . The rosebushes were finally in full bloom on that spring morning.

The sight of roses always brings to________Wanda’s childhood memories. Then the family had no _____to buy extra things, so even a tired rose was something to ________ .

Currently, to have a backyard full of different roses is pure ________. And her husband, Dale, devotedly ________the roses. ________that she loves the very first blooms, he picked some on this particular morning.

But as Dale returned, he came across a neighbor who had________ for a quick visit. As the woman turned to go, Dale generously gave the ________ to her. And even though their visitor ______ she didn’t want to take them, she was_______ assured (确信) that the flowers were hers to keep.

Seeing her precious first blooms go out the door________Wanda with regret, and a bit of ________. She knew it was “better to give than to receive.” ________, she wished she could have kept the roses for herself.

Later that day, the couple headed to the post office, where Wanda waited outside in the car.

Then, without_______, an older woman suddenly appeared at the open window, and gave her a bunch of fresh roses!“These are for you. They’re my first blooms this spring.”

Completely ________,Wanda thanked the woman and_______ for a moment to breathe in the rich fragrance. When she looked back, the mysterious visitor was gone.

That special______changed Wanda. It made her understand the true meaning of_________gifts. Now, she always_______her first blooms to others , as a(n)________that someone is thinking of them.

4 . London (CNN) There is no God -- that's the conclusion of the well-known physicist Stephen Hawking, whose final book is published on Tuesday. The book Brief Answers to the Big Questions, which was completed by his family after his death, presents answers to the questions that Hawking said he received most during his time on Earth.

Other bombshells(爆炸性事件)the British scientist left his readers with include the belief that alien life is out there, artificial intelligence could outsmart humans and time travel can't be impossible.

"There is no God. No one directs the universe," he writes in the book." For centuries, it was believed that disabled people like me were living under a curse by God," he adds. "I prefer to think that everything can be explained another way, by the laws of nature."

While Hawking spoke of his lack of belief in God during his life, several of his other answers are more surprising. "There are forms of intelligent life out there," he writes. "We need to be cautious about answering back until we have developed a bit further."

"Travel back in time can't be ruled out according to our present understanding," he says. He also predicts that "within the next hundred years we will be able to travel to anywhere in the Solar System."

In remarks prepared by Hawking and played at the launch of the book in London on Monday, the scientist also turned his attention to the world he was leaving behind. His greatest concern, his daughter said, "is how divided we've become," adding ,"He makes this comment about how we seem to have lost the ability to look outward, and we are increasingly looking inward to ourselves."

Hawking's final message to readers, though, is a hopeful one. Attempting to answer the question "How do we shape the future?", the scientist writes, "Remember to look up at the stars and not down at your feet."

1. Which question is NOT probably included in the book Brief Answers to the Big Questions,?

A．Is there alien life?	B．Does anyone direct the universe?
C．Is time travel possible?	D．Does the solar system exist?

2. Hawking mentioned his disability in his book to________.

A．show his confidence.	B．support his disbelief in God.
C．tell readers about his hardship.	D．complain of God

3. What was Hawking most concerned about?

A．Artificial intelligence will outsmart humans.

B．Human beings are not united.

C．Technology will destroy the world.

D．Allen life will come to the earth some day.

4. What did Hawking suggest human beings do?

A．Contact alien life.	B．Respect artificial intelligence.
C．Develop the earth.	D．Explore the universe.

5 . Chinese researchers say they have come up with a simple way to find out a person’s biological age — how much the body has aged physically — through a urine (尿) test.

Their findings will help researchers conduct numbers of ageing studies and even predict a person’s risk of age-related diseases, according to a paper published in the journal Frontiers in Ageing Neuroscience.

Another paper by researchers at the Beijing Hospital and the West China Hospital in Chengdu, Sichuan province, said on Tuesday that people aged at different rates due to changes in their genetic make-up and their environment.

Chronological age — which is based on one’s birth date — was not an exact measure of biological age so a more exact method was needed, the team said.

Ageing is driven by the lifelong gradual accumulation (积累) of a broad variety of molecular (分子) faults in the body’s cells. The team said they had identified a matter 8-oxoGsn   that indicated increases in oxidative (氧化性) damage in urine as people’s bodies aged.

Cai Jianping, a co-author at the Beijing Hospital, said: “As we age, we suffer increasing oxidative damage and so the levels of oxidative matters increase in our body.” The team tested the levels of 8-oxoGsn in urine samples from 1,228 Chinese people aged two to 90 and concluded the marker helped accurately determine the stage of biological ageing in adults.

They had previously found that 8-oxoGsn levels also increased with age in the urine of animals such as mice.

The team has also developed a rapid analysis technique called ultra-high-performance liquid chromatography (层析法), which can process up to 10 urine samples an hour, according to the study.

1. Scientifically speaking, by what does a doctor judge the stage of a person getting old?

A．His psychology.	B．His condition.
C．His biological age.	D．His chronological age.

2. What are the outer factors the speed of one’s ageing physically depend on?

A．One’s birth date.

B．The changes in their genetic make-up and their environment.

C．The accumulation of various molecular faults in the body’s cells.

D．The increases in oxidative damage in urine.

3. Which can take the place of the underlined word “marker” in the sixth paragraph?

A．Molecular faults.	B．8-oxoGsn.
C．Oxidative damage.	D．Stage of biological ageing in adults.

4. What is the passage about?

A．Why people are ageing.

B．What determines the stage of people’s ageing physically.

C．A rapid method with which to judge how much people are aging physically.

D．How to delay people’s ageing physically.

6 . The best bikes for the beginners

When it comes to purchasing your first bike, the choice is endless, making it tough to know what to go for. Here are the best buys on the market right now.
