2 . If something that you’re doing doesn’t challenge you, then it doesn’t change you. We all need some normal stress in our lives, after all.     1     So challenge the following limits:

1.Figure out what you’re scared of and do it continuously.

If you’re a salesman, and you’re scared of talking to people personally or over the phone now, instead of being scared and thinking you’ll fail, spend at least five minutes a day to pick up the phone and make a call.     2     But don’t stop on the first try! Eventually, you can look at fear in the eye and say, “Go on. I’m not scared!”

2.     3    

Make sure this hobby is not linked to your career; you have to relax and relieve your stress while performing this. Some examples might be cooking, sewing, painting and so on. Apart from helping you challenge yourself, taking a class for your hobby may also give you extra income.

3. Set aside at least nine minutes a day for physical exercise.

    4     A simple 9-minute run around your neighborhood can do wonders for yourself. Exercise can not only help you maintain your regular weight, but also make you feel better about yourself.

4.Travel and allow yourself to be interested in new people.

Don’t just limit yourself to your fellow travelers, try to connect with the service staff. You never know what kind of people they’re going to be. Get out of your house or go online to book your ticket right now.     5    

A．Someone may hang up on you.

B．You should do it continuously.

C．You don’t need to go to the gym.

D．Running in the gym may be a better choice.

E．Start to travel now and learn to challenge yourself.

F．Take a class for a hobby you’ve been wanting to develop.

G．You can never see any improvement if you stick to your comfort zone.

7 . You run into the grocery store to pick up one bottle of water. You get what you need, head to the front, and choose the line that looks fastest.

You chose wrong. People who you swear got in other lines long after you are already checked out and off to the parking lot.     1    

It turns out, it’s just math working against you; chances are, the other line really is faster.

Grocery stores try to have enough employees at checkout to get all their customers through with minimum delay.     2    Any small interruption-a price check, a chatty customer-can have downstream effects, holding up an entire line.

If there are three lines in the store, delays will happen randomly at different registers. Think about the probability:    3    So it's not just in your mind: Another line probably is moving faster.

Researchers have a good way to deal with this problem. Make all customers stand in one long, snaking line- called a serpentine line-and serve each person at the front with the next available register.     4    This is what they do at most banks and fast-food restaurants. With a serpentine line, a long delay at one register won't unfairly punish the people who lined up behind it. Instead, it will slow down everyone a little bit but speed up checkout overall.

    5    It takes many registers to keep one line moving quickly, and some stores can't afford the space or manpower. So wherever your next wait may be: Good luck.

A．Why does this always seem to happen to you?

B．So why don’t most places encourage serpentine lines?

C．Some of the may have stood in a queue for almost an hour.

D．The chances of your line being the fastest are only one in three.

E．How high is the probability that you are in the fastest waiting line?

F．With three registers, this method is much faster than the traditional approach.

G．But sometimes, as on a Sunday afternoon, the system gets particularly busy.

8 . At the start of the 20th century, an American engineer named John Elfreth Watkins made predictions about life today. His predictions about slowing population growth, mobile phones and increasing height were close to the mark. But he was wrong in one prediction: that everybody would walk 10 miles a day.

Today, in Australia, most children on average fall 2, 000 steps short of the physical activity they need to avoid being overweight. In the early 1970s, 40 per cent of children walked to school, while in 2010, it was as low as 15 percent.

The decline is not because we have all become lazy. Families are pressed for time, many with both parents working to pay for their house, often working hours not of their choosing, living in car-dependent neighborhoods with limited public transport.

The other side of the coin is equally a deprivation: for health and well-being, as well as lost opportunities (机会) for children to get to know their local surroundings. And for parents there are lost opportunities to walk and talk with their young scholar about their day.

Most parents will have eagerly asked their child about their day, only to meet with a “good”, quickly followed by “I’m hungry”. This is also my experience as a mother. But somewhere over the daily walk more about my son’s day comes out. I hear him making sense of friendship and its limits. This is the unexpected and rare parental opportunity to hear more.

Many primary schools support walking school-bus routes (路线), with days of regular,   parent-accompanied walks. Doing just one of these a few times a week is better than nothing. It can be tough to begin and takes a little planning-running shoes by the front door, lunches made the night before, umbrellas on rainy days and hats on hot ones-but it's certainly worth trying.

1. Why does the author mention Watkins' predictions in the first paragraph?

A．To make comparisons.	B．To introduce the topic.
C．To support her argument.	D．To provide examples.

2. What has caused the decrease in Australian children’s physical activity?

A．Plain laziness.	B．Health problems.
C．Lack of time.	D．Security concerns.

3. Why does the author find walking with her son worthwhile?

A．She can get relaxed after work.	B．She can keep physically fit.
C．She can help with her son's study.	D．She can know her son better.

9 . Researchers say they have translated the meaning of gestures that wild chimpanzees (黑猩猩) use to communicate. They say wild chimps communicate 19 specific messages to one another with a “vocabulary” of 66 gestures. The scientists discovered this by following and filming groups of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.

Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.

“That’s what’s so amazing about chimp gestures,” she said. “They’re the only thing that looks like human language in that respect.”

Although previous research has shown that apes and monkeys can understand complex information from another animal’s call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.

Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signaling: “Climb on me.” The youngster immediately jumps on to its mothers back and they travel off together. “The big message from this study is that there is another species (物种) out there. that is meaningful in its communication, so that’s not unique to humans,” said Dr Hobaiter.

Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were “a little disappointing”.

“The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions,” she said. “Moreover, the meanings seem to not go beyond what other animal convey with non-verbal communication. So, it seems the gulf remains. ”

1. What do chimps and humans have in common according to Dr Hobaiter?

A．Memorizing specific words.	B．Understanding complex information.

A．It was well designed but poorly conducted.

B．It was a good try but the findings were limited.

D．It was a failure but the methods deserved praise.

3. What does the underlined word “gulf” in the last paragraph mean?

A．Difference.

B．Conflict.

C．Balance.

D．Connection.

4. Which of the following is the best title for the text?

A．Chimpanzee behaviour study achieved a breakthrough

B．Chimpanzees developed specific communication skills

C．Chimpanzees: the smartest species in the animal kingdom

D．Chimpanzee language: communication gestures translated

10 . More than 25 years ago, Saroo Brierley lived in rural（农村）India. One day, he played with his brother along the rail line and fell asleep. When he woke up and found himself alone, the 4-year-old decided his brother might be on the train he saw in front of him-so he got on.

That train took him a thousand miles across the country to a totally strange city. He lived on the streets, and then in an orphanage（孤儿院）. There, he was adopted by an Australian family and flown to Tasmania.

As he writes in his new book, A Long Way Home, Brierley couldn't help but wonder about his hometown back in India. He remembered landmarks, but since he didn't know his town's name, finding a small neighborhood in a vast country proved to be impossible.

Then he found a digital mapping program. He spent years searching for his hometown in the program's satellite pictures. In 2011, he came across something familiar. He studied it and realized he was looking at a town's central business district from a bird's-eye view. He thought,   “On the right-hand side you should see the three-platform train station”—and there it was. "And on the left-hand side you should see a big fountain"-and there it was. Everything just started to match.

When he stood in front of the house where he grew up as a child, he saw a lady standing in the entrance. "There's something about me, " he thought—and it took him a few seconds but he finally remembered what she used to look like.

In an interview Brierley says, "My mother looked so much shorter than I remembered. But she came forth and walked forward, and I walked forward, and my feelings and tears and the chemical in my brain, you know, it was like a nuclear fusion（核聚变）. I just didn't know what to say, because I never thought seeing my mother would ever come true. And here I am, standing in front of her. ”
