2 . Compassion and love are concepts that are often thought to be felt by humans only. As the most intelligent creatures to ever walk the earth, we tend to assume that we are the only ones who can feel emotions. We forget that the speechless beings who live here with us—animals—also have the same capability.

During a cold night in Ontario, Canada, a passer-by spotted something on the side of the road that made her stop-a shaking dog curled up in the snow.

When she approached the pet, she discovered that she wasn't alone—she was cuddling five orphaned black kittens to keep them warm.

The dog surely could have found a safer place to stay for the night, but she chose instead to help not just herself but other stray animals as well.

The Good Samaritan called Pet and Wildlife Rescue and an animal control officer picked them up. When they got to the shelter, it was apparent that a close bond had already been formed between the dog and the orphaned kittens. The staff decided to name the kind dog Serenity in honor of her selfless act.

“It's truly heartwarming!” a shelter spokesperson told The Dodo. "It had been a very cold night so these kittens would have had a very hard time surviving.”

Aside from requiring treatment for worm and flea infections, the orphaned kittens are now safe. Just like a proud and doting mother, Serenity insisted on checking on her babies regularly to oversee their progress.

The good news is that the kittens are now living with a foster family who will care for them until they are old enough to be adopted. Serenity, on the other hand, is still looking for a family.

According to the shelter, she loves zooming around in the yard and is big on playing. She is also quite jumpy, so she would do best in a home without small children.

1. What did the passer-by see on the road?

A．A dog curled up in the snow.

B．Five kittens were in the snow alone.

C．A dog found a safe place to stay for the

C．Staying with the kittens.	D．Playing with some children.

4. What can we draw from the story?

A．Animals have the same capability with humans.

B．A sad end can be turned into a positive one.

C．Animals and humans should live in harmony.

D．Animals can feel compassion and love like humans.

3 . 阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。

I went up to the roof for a break after studying for an hour and watched the 50 or so people swimming in the natural rock pool below our house. It was a sunny day--a blue, cloudless sky over a calm sea. But then, as I looked in the distance, I discovered three or four big waves heading towards the shore. I'd seen these mini-tsunamis(海啸) many times before. They were heading at speed in the direction of the pool. Most people knew how to look out for them, but from the screams that started coming from the beach, I could tell someone was in trouble.

Without thinking, I ran down into the street, holding my body board(俯伏冲浪板) on the way and shouted at a stranger to go inside my house and call the coastguard. My neighbor Moises had heard the screaming as well and was also outside with his body board, so together we rushed to the steps that led down to the sea.

Once we got closer, we discovered the waves had pulled a boy and a girl from the pool and into the open sea. I knew that the nearest boat would take at least 30 minutes to reach us. Waiting for help wasn't a choice. I wasn't used to this sort of emergency--I’d never been trained as a lifeguard-but I didn't think twice about trying to save them. I supposed in a way I wanted to impress everyone: at 19, a deal like that can seem like a good opportunity to show off.

Moises and I dived into the water and it took us 10 minutes to get to them. When we finally reached them, they were almost lifeless with only their heads coming in and out of the water. We could tell they were still alive from their small breaths but it was clear they wouldn't have been able to stay there much longer. I held the boy and pulled him over my board. Moises moved the girl onto his board. We discussed pushing them back to the shore, but we were too far out.

6 . For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.

Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.

To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.

Then, on two separate morning visits to the scientists’ lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.

Just before and an hour after each workout, the scientists took additional samples of the men’s blood and fat tissue.

Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.

But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.

The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.

1. The underlined expression “stomach it” in Paragraph 1 most probably means “______”.

A．digest the meal easily	B．manage without breakfast
C．decide wisely what to eat	D．eat whatever is offered

2. Why were the 10 people chosen for the experiment?

A．Their lifestyles were typical of ordinary people.

B．Their lack of exercise led to overweight.

C．They could walk at an average speed.

D．They had slow metabolic rates.

3. What happened to those who ate breakfast before exercise?

A．They successfully lost weight.	B．They consumed a bit more calories.
C．They burned more fat on average.	D．They displayed higher insulin levels.

4. What could be learned from the research?

A．A workout after breakfast improves gene performances.

B．Too much workout often slows metabolic rates.

C．Lifestyle is not as important as morning exercise.

D．Physical exercise before breakfast is better for health.

7 . Babies’ Look Changing

Researchers show that the early social behavior called look changing is linked to babies’ ability to learn new language sounds.     1    . It is when a baby makes eye contact and then looks at the same object that the other person is looking at.

Rechel Brooks, one of the researchers, made a report, showing that babies’ look changing serves as a building block（基础）for more complicated language and social skills.     2    .

In this experiment, nine 5-month-old babies from English-speaking families attended foreign language tutoring sessions. Over four weeks, the tutors talked and played with toys while speaking Spanish.

At the beginning and end of the four-week period, researchers counted how often the babies changed their look.     3    . There they tested how much Spanish language sounds.

    4    . The more look changing the babies participate in during their tutoring sessions, the greater their brain response were to the Spanish language sounds.

“Our findings show young babies’ social engagement contributes to their own language learning – they’re not just passive listeners of language,” Brooks said. “They’re paying attention and showing parents they’re ready to learn when they’re looking back and forth.”     5    .

The researchers hope their findings help people develop strategies for teaching young children.

A．That’s when the most learning happens

B．These skills are what preschool children can gain

C．The results were really amazing

D．We can’t imagine how look changing helps them learn so much

E．However, others may regard look changing as something useless

F．Look changing is one of the earliest social skills that babies show

G．After the experiment ended, the researchers brought the babies back to the lab

8 . 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。

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育)    4     nature, as a mother's lifestyle appears     5    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

9 . A Leap（跳跃）to Honor. Leaping on a narrow balance beam（平衡木） is not easy. But Lola Walter, a 13-year-old gymnast, is an expert at it.

She likes the determination it takes to do the sport. Her biggest __________ is the balance beam. Because she has double vision, she often sees two beams. She must use her sense of touch to help her during her routine. Sometimes she even closes her eyes. “You have to ________ your mind that it’ll take you where you want to go,” says Lola.

To be a top-level gymnast, one must be brave. The beam is probably the most ___________ for anyone because it’s four inches wide. At the state competition, Lola didn’t fall ___________ the beam. In fact, she got an 8.1 out of 10---- her highest score yet.

Lola doesn’t want to be _____________   differently from the other girls on her team. At the competitions, the judges don’t know about her vision ____________. She doesn’t tell them, because she doesn’t think they need to know. Her mom is amazed by her __________ attitude.

10 . Hollywood’s theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics（控制论）, put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”

A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.

The possibility of entering into and losing such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.

Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.
