1 . Today's world is not an easy adjustment for young adults. Key skill set for success is persistence (毅力), a characteristic that researchers say is heavily influenced by fathers. Researchers from Brigham Young University discovered that fathers are in a unique position to help their adolescent children learn persistence.

BYU professors Laura Padilla-Walker and Randal Day arrived at these findings after following 325 American families over several years. And over time，the persistence gained through fathers led to higher achievement in school.

"There are relatively few studies that stress the unique role of fathers，"Padilla-Walker said. "This research also helps to prove that characteristics such as persistence-which can be taught-are key to a child's life success.”

Researchers determined that dads need to practice an "authoritative" parenting style. Authoritative parenting is not authoritarian:rigid，demanding or controlling. Rather，an authoritative parenting style includes some of the following characteristics:children feel warmth and love from their father；responsibility and the reasons behind rules are stressed children are given an appropriate level of autonomy(自主权).

In the study，about 52 percent of the dads exhibited above-average levels of authoritative parenting. A key finding is that over time，children raised by an authoritative father were significantly more likely to develop persistence，which leads to better outcomes in school.

This particular study examined 11 to 14-year-olds living in two-parent homes. Yet the researchers suggest that single parents still may play a role in teaching the benefits of persistence，which is an avenue of future research.

2 . 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?

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.

3 . The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don’t know. By next year, half of the calls we receive will be scams(欺诈). We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it’s too little, too late. By the time these “solutions”(解决方案) become widely available, scammers will have moved onto cleverer means. In the near future, it’s not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you’re hearing is actually real.

That’s because there are a number of powerful voice manipulation(处理) and automation technologies that are about to become widely available for anyone to use. At this year’s I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.

These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches(数据侵入) of personal information has led to a situation where scammers can easily learn your mother’s name, and far more. Armed with this knowledge, they’re able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller’s, tricking you into “confirming” your address, mother’s name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.

We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications—using apps like FaceTime or WhatsApp, which can be tied to your identity.

Credibility is hard to earn but easy to lose, and the problem is only going to get harder from here on out.

5 . Alice Moore is a teenager entrepreneur(创业者), who in May 2015 set up her business AilieCandy. By the time she was 13, her company was worth millions of dollars with the invention of a super-sweet treat that could save kids’ teeth, instead of destroying them.

It all began when Moore visited a bank with her dad. On the outing, she was offered a candy bar. However, her dad reminded her that sugary treats were bad for her teeth. But Moore was sick of missing out on candies. So she desired to get round the warning, “Why can’t I make a healthy candy that’s good for my teeth so that my parents can’t say no to it?” With that in mind, Moore asked her dad if she could start her own candy company. He recommended that she do some research and talk to dentists about what a healthier candy would contain.

With her dad’s permission, she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly. She also approached dentists to learn more about teeth cleaning. Consequently, she succeeded in making a kind of candy only using natural sweeteners, which can reduce oral bacteria.

Moore then used her savings to get her business off the ground. Afterwards, she and her father secured their first business meeting with a supermarket owner, who finally agreed to sell Moore’s product—CanCandy.

As CanCandy’s success grows, so does Moore’s credibility as a young entrepreneur. Moore is enthusiastic about the candy she created, and she’s also positive about what the future might bring. She hopes that every kid can have a clean mouth and a broad smile.

Meanwhile, with her parents’ help, Moore is generally able to live a normal teenage life. Although she founded her company early on in life, she wasn’t driven primarily by profit. Moore wants to use her unique talent to help others find their smiles. She donates 10% of AilicCandy’s profits to Big Smiles. With her talent and determination, it appears that the sky could be the limit for Alice Moore.

7 . When I mentioned to some friends that we all have accents, most of them proudly replied, “Well, I speak perfect English/Chinese/etc.” But this kind of misses the point.

More often than not, what we mean when we say someone “has an accent” is that their accent is different from the local one, or that pronunciations are different from our own. But this definition of accents is limiting and could give rise to prejudice. Funnily enough, in terms of the language study, every person speaks with an accent. It is the regular differences in how we produce sounds that define our accents. Even if you don’t hear it yourself, you speak with some sort of accent. In this sense, it’s pointless to point out that someone“has an accent“. We all do!

Every person speaks a dialect , too. In the field of language study, a dialect is a version of a language that is characterized by its variations of structure, phrases and words. For instance,“ You got eat or not? ”(meaning “Have you eaten?” ) is an acceptable and understood question in Singapore Oral English. The fact that this expression would cause a standard American English speaker to take pause doesn’t mean that Singapore Oral English is “wrong” or “ungrammatical”. The sentence is well-formed and clearly communicative, according to native Singapore English speakers’ solid system of grammar. Why should it be wrong just because it’s different?

We need to move beyond a narrow conception of accents and dialects — for the benefit of everyone.

Language differences like these provide insights into people’s cultural experiences and backgrounds. In a global age, the way one speaks is a distinct part of one’s identity. Most people would be happy to talk about the cultures behind their speech. We’d learn more about the world we live in and make friends along the way.

8 . If anyone had told me three years ago that I would be spending most of my weekends camping, I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me.     1    

The friends who introduced me to camping thought that it meant to be a pioneer.     2     We slept in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor’s bill for my son’s food poisoning.

I was, nevertheless, talked into going on another fun-filled holiday in the wilderness.     3     Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.

    4     We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.

    5     It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.

A．This time there was no tent.

B．Things are going to be improved.

C．The trip they took me on was a rough one.

D．I was to learn a lot about camping since then, however.

E．I must say that I have certainly come to enjoy camping.

F．After the trip, my family became quite interested in camping.

G．There was no shade as the trees were no more than 3 feet tall.
