21、NASA on September 28, 2015 announced the strongest evidence yet for liquid water on the red planet, increasing the possibility that astronauts journeying to Mars could someday rely on the planet's own water for their drinking needs.

  You may feel like you've heard about the hunt for liquid water on Mars before—and the researchers involved know it may seem played out. But science has yet to truly prove that water flows on Mars once and for all, and doing so could completely change the way we view the planet. This new data is a big step in the right direction.

"Liquid water is an attractive topic, and we like the thousandth time someone has discovered water on Mars," Lujendra Ojha, the Georgia Tech PhD candidate who led the research announced Monday, told The Post. But there's a good reason that liquid water is so "attractive": Mars is now the only planet in our solar system to show evidence of the stuff on its surface, other than our own. Other worlds have it in subsurface oceans, or scattered around as vapor in the atmosphere. But Mars is the only place where we have solid evidence for liquid that sits right there in the open air. While it would be a major leap to suggest that Mars might harbor life—even microbial life—liquid water at least makes it possible that parts of the planet are habitable.

The study builds on research from April, when scientists using data from the Curiosity rover noted that the planet had the seasonal potential for liquid water. We know that because of the extremely low pressure on Mars, water has a boiling point of just a few degrees Celsius, after which it evaporates. The April study noted the presence of perchlorates (高氯酸盐) —a kind of salt—which could make the boiling point of Mars' water much higher, theoretically allowing it to remain liquid. They affirmed that the planet's temperature would be right for liquid, perchlorate-filled water to form every day during winter and spring.

【1】What does the Paragraph 2 mainly tell us?

A. The significance of the discovery.

B. The doubt of the discovery. 

C. The difficulty of the discovery.

D. The expense of the discovery.

【2】The underlined words "our own" in Paragraph 3 refer to ________.

A. Mars

B. the earth

C. liquid water

D. the solar system

【3】 What plays an important role in making Mars' water in the state of liquid?

A. The thick atmosphere around Mars.

B. The physical structure of Mars.

C. The extremely low pressure on Mars.

D. Perchlorates in Mar's water.

【4】 The best title for the passage can be "________".

A. Water on Mars could be used for dringking

B. There might be some kinds of life on Mars

C. NASA would send astronauts to journey to Mars

D. NASA confirms the best-ever evidence for water on Mars

22、There’s just a 1 in 3, 700, 000 chance that a person will be killed by a shark in their lifetime, but the fear is still enough to have swimmers worrying about being perceived as prey (猎物). Now, new research supports the long-standing theory that when great whites do go in for a bite, it’s a case of “mistaken identity”.

A team of biologists from the UK and Australia compared videos of seals swimming with videos of humans swimming. They then edited the videos to simulate (模拟) a great white’s vision — the sharks are likely colorblind, and they can’t make out fine detail-and found that from the point of view of the ocean creatures, humans do indeed bear a strong resemblance to seals.

“Great white sharks are often regarded as ‘mindless killers’ and ‘fond of human flesh’. However, that's not the case — we just look like their food,” Laura Ryan, lead author of the study, said.

Despite their dissatisfying vision and spatial perception, great white sharks are highly visual creatures, and rely on motion and shadows when on the lookout for prey. To really see through the species’s eyes, the research team had to get creative.

“We attached a camera to an underwater scooter (轻便小车), and set it to travel at a typical speed for predatory sharks,” Ryan said in a statement. The researchers then paired the recordings with computer models to simulate how similar people look from a shark's view below the surface.

“I knew there would be some similarities, but not to the extent we have found,” Ryan said. “Specifically, I thought swimmers might not be as similar as surfers to seals as they typically aren’t involved in as many shark bites. However, the swimmers are also difficult to tell apart from seals.”

Ryan put it in a statement, “Understanding why shark bites occur can help us find ways to prevent them, while keeping both humans and sharks safer.”

【1】What do the underlined words “the ocean creatures” in paragraph 2 refer to?

A．Seals.

B．Sharks.

C．Humans.

D．Swimmers.

【2】Why did the researchers use the scooter with a camera?

A．To measure the speed of predatory sharks.

B．To take clear pictures of underwater seals.

C．To keep track of sharks’ travel underwater.

D．To see human beings through sharks' view.

【3】What does the research find?

A．Swimmers are easy to tell apart from seals.

B．Swimmers are not as similar as surfers to seals.

C．The similarities between humans and seals are few.

D．Swimmers surprisingly resemble seals in sharks’ eyes.

【4】Which of the following can be a suitable title for the text?

A．Why Sharks Attack Humans

B．Are Shark Bites Common?

C．How Sharks Hunt for Food

D．Are Sharks Really Dangerous?

23、   When I was first married to my wife, I lived and worked in Ontario, moving from small town to big city as I pursued my career as a radio broadcaster. We have two sons, both of whom were born in Toronto, but they moved, with us, to Ottawa when they were quite young. They grew up there, and then, chasing their own careers, they also moved. One went to Canada's east coast near a city called Halifax and the other headed to the west coast to Vancouver. We had a dilemma; we were left in the middle.

At the time I was still working and my job was in Ottawa. However, as we began to consider retirement we wondered where we should spend our final years. We couldn't be close to both of our children and there was no telling when they might again relocate. For several reasons we settled on a small town on Vancouver Island. At least we were close to one of them. However, he had his sights set on Hollywood and, when an opportunity presented itself, he left Canada and headed south. I helped him move.

So, there we were, and still are, in our little west coast town. We love our little corner of paradise but we have paid a price. We have not been there for some important events such as the births of two of our grandchildren. We have missed watching each of them grow up; we have missed the normal, noisy households that have young people in them. Our home, while very comfortable, is also very quiet.

Every fall we travel to see the children. We usually fly, first to California to see our son Scott and spend a week or more with him trying to catch up on everything we've missed. Then, usually in November, we make the even longer trip east across Canada to see Travis and our grandchildren, who are now teenagers, actually into their twenties. They seldom come to visit us. The distances are just too great and it is costly.

Fortunately, both our boys are doing well and our grandchildren are growing up straight and tall. We love all of them and we are secure in the knowledge that they love us but the reality is that they don't need us. We have done our jobs and, at least in theory, we can sit back, relax and enjoy the time remaining to us. They have also missed having a set of parents and grandparents around.

Life has been good for our family but we have all paid a price.

【1】What's the dilemma ( Pa. 1) to the author and his wife?

A.The situation where they were not happy about their sons' absence.

B.The fact that they were unwilling to separate from their sons.

C.The fact that they were not yet prepared for retirement at that time.

D.The situation where they couldn't decide which son to live with.

【2】The reason why the author says they have paid a price is that ______.

A.they have lost lots of money because of his retirement

B.they have to pay a large sum of money to their sons

C.they have been absent from their children's life

D.they have to afford very expensive fare to visit their sons

【3】Why do not the authors grandchildren visit them regularly?

A.They are quite occupied with their homework.

B.It's not easy for the kids to visit their grandparents.

C.They don't need their grandparents any more.

D.The weather of winter in Canada is very awful.

【4】What is the best title for the text?

A.A Price to Pay B.Suffering Separation

C.Love Actually D.Hidden Emotions

24、   If there had to be a father of handwashing in history, it would be Ignaz Semmelweis. While working at Vienna General hospital, the Hungarian doctor, faced with a situation in which maternal death (孕产妇死亡) in hospitals were significantly higher than local clinics, tried hard clues as to why.

Germs (细菌) were yet to be discovered, and it was still believed in the 1840s that disease was spread by bad smells in the air. So it didn’t seem a problem that trainee doctors hanging out of labs to dissect (解剖) human bodies would pop up to the maternity ward (产房) to deliver a baby without washing their hands.

Then an accidental finger cut by a knife during a dissection caused a doctor to die, seemingly of the same sign the mothers had been getting. Semmelweis assumed that something from the dead bodies was to blame, which might, through the hands of doctors, make their way into women’ s bodies during childbirth.

To test his theory, he ordered doctors to wash their hands and instruments in some chlorine solution. As a result, the death rate for new mothers dropped to about 1 percent, compared with that of as high as 18 percent before the experiment.

However, he faced great resistance, and met a sad end. People at that time didn’t think of themselves as sort of walking Petri dishes. And the majority of doctors then were from middle- or upper-class families, and thought of themselves as very clean people.

Over the next 40 years, a better understanding of germs developed, and attitudes to hygiene (卫生) gradually shifted. In 1876, the German scientist Robert Koch discovered the anthrax bacillus (炭疽), kicking off the new research field of medical bacteriology. Many more germs were later identified. Surgeons started to take handwashing seriously.

By the 1890s and into the early 1900s, handwashing moved from being something doctors did to something everybody had been told to do.

【1】What was the situation like in the 1840s?

A．Germs might have been discovered then.

B．Women suffered from delivering babies then.

C．The air at that time was dirty and full of viruses.

D．People were unaware of how disease was spread.

【2】What does the underlined word “Solution” probably mean?

A．Liquid.

B．Option.

C．Tissue.

D．Shell.

【3】How did the public feel about handwashing at first?

A．It was effective.

B．It was necessary.

C．It was ridiculous.

D．It was dangerous.

【4】Which of the following can be the best title of the passage?

A．Steps to Protect Yourself

B．Disease Spreading by Your Hand

C．Hand Washing Critical in Fighting Viruses

D．The First Recorded Discovery of Handwashing

26、阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

When my daughters reached the third and fourth grades, I sometimes allowed them to walk to and from school alone if the weather permitted. One warm spring day, a little dog followed them home after school. It had short legs and long lovely ears. It was the cutest dog I had ever seen and the girls begged me to keep it.

The dog was about twelve weeks old. It had no collar(项圈) or identifying marks of any sort. I didn’t know what to do. I thought about posting an advertisement but I really didn’t want to. It would break the kids’ hearts if someone should show up. Besides, its owners should have watched it more closely.

By the end of the week the dog was part of our family. It was very intelligent and good with the girls. The following week something told me to check the lost—and—found section in the local paper. One particular advertisement jumped out at me and my heart beat with fear for what I read. Someone was begging for the return of a lost dog in the neighborhood of our grade school. They sounded extremely eager. My hand shook, couldn’t bring myself to pick up the paper.

Instead, I pretended I hadn’t seen the advertisement. I quickly put paper away in the drawer and continued with my dusting. I never said a word about it to the kids or my husband.

By now we had named the dog. It looked like a Molly, so that was what we called it. It followed the girls everywhere they went. When they went outside, it was one step behind them. When they did the housework, it was there to lend a hand.

There was only one problem with this seemingly perfect picture: my conscience(良心)was bothering me. I knew in my heart I had to call that number in the paper and see if our Molly was the dog they were desperately seeking. It was the most difficult thing I’ve ever done.

注意:
