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.

It is true that shyness can be a disadvantage socially for those who suffer from it seriously. I mean real shyness, not somebody who is simply quiet. Quiet people could be shy, but on the other hand, they may just be observing because they are unsure of you or others in your company. They may be capable of being extrovert (性格外向的) and sociable, but on some particular occasions, they are quiet.
I have learnt from my experience that those who observe and listen more and talk less can gain a position of strength. This means that even a very shy person, the type who is reluctant to talk in company (在交际场合) , especially new company, can become a strong person in just about anything they choose. Remember, knowledge is power, and a shy introvert (性格内向的人) is in a better position to gain knowledge than an extrovert. Introverted people can give great attention to learning, and as good listeners they can take in an enormous amount from others. Over time, people can come to respect them far more than the extrovert who speaks a lot. Usually about themselves.
What does it take , then for a very shy person to be that successful person they have always wanted to be ? They may only need one more thing to push themselves on their way. They need to dare themselves to take the leap; and when they do , they will probably find all the knowledge they have gained over the years will help them on their way to the top in their chosen field.
1.What does the first paragraph mainly want to tell us?
A. A person who is quiet may not be shy. B. A shy person may not be a calm one.
C. Quiet people are usually doubtful. D. Shyness is sometimes a bad feature.
2.The underlined word “reluctant” in paragraph 2 probably means ________.
A. lazy B. careful C. eager D. unwilling
3.According to the author, introverted people can be successful because they usually ________.
A. have a strong will B. talk less and show off less
C. learn more than extroverts D. have a good attitude to learning
4.It can be learned from the last paragraph that “one more thing” probably refers to ________.
A. energy B. courage C. quietness D. knowledge

For many people – especially those juggling (兼顾) family and work at the same time --- it can be difficult to stick with a college degree. Kathy Bitzthum thought many times about dropping out of her accounting program at Iowa State University: She had two children and a job at Electronic Technology Corp. She’d only enrolled in the first place because her boss would offer her a promotion if she took a few accounting courses.
Because she only had enough time to take one class at a time, it took her seven years to complete the courses her boss asked her to take on. She received the promotion as her boss promised and wasn’t planning to continue a degree. But a request from her father, who was dying of cancer, made her think twice. He said to her, “Kathy, why don’t you just keep going and get your degree?”
Before he passed away, he made her promise that she would finish it. And he made her a promise in turn. Vitzthum’s parents had agreed to give each of their children a valuable gift when they graduated from college, and Vitzthum was obsessed with an antique she’d come across and knew that she couldn’t afford. After she promised to graduate from college, her parents bought her the antique. Her father told her, “I’m not going to be around when you graduate, so I’ll give this to you now. But it doesn’t _________ until you graduate from college.”
Since then, Vitzthum has looked at that antique every day and remembered the promise she had made to her father. Despite a hectic life as a wife, mother and full-time employee, she’s taken one course every semester for the last 19 years. And finally, at the age of 48, she graduated with a bachelor’s degree in accounting --- and she was excited to accept full ownership (所有权) of the antique that she’d borrowed for more than a decade.

What to endure before publication?
It takes a lot to write a novel. Even those who haven’t tried would say, “Well, duh!” to this. But it’s not much the mind space or the considerable time it takes to write a novel that is as discouraging as how many times any writer must go back to the drawing board for yet another draft. To really ready a novel for publication, a writer must spend time with his or her book. Like any promising relationship, you, the writer , must date your novel, take it out to dinner, meet its parents, and see it through its most trying and desperate times. As a writer, you have to stay up all night with your novel crying and talking and sometimes even pulling your hair out before that perfect moment of inspiration can truly help you cross the finish line.
For many published authors I know, myself included, a completed novel takes them about 10, that’s right, 10 drafts, and at least a year of real editing. Will you be spending every single second editing your novel? No, of course not. Just as drafts need some real time on the surgery table, they also need rest in the recovery room. You don’t nurse a relationship by spending every waking second with them until you can’t stand the sight of each other, and you can’t produce a novel by breathing down its literary neck. However, a novel should undergo many drafts---and different kinds of drafts—before declaring it ready for an agent or editor to see.
Everyone has their own way to write a novel, and not all craft advice (or even craft “rules”) should all be followed by everyone, but when it comes to the many drafts of a novel, there are specific things a writer should focus on during each revision to help create a smooth transition from the initial idea to final products.
1.People are discouraged from writing a novel mainly because it requires _____.
A. a good publisher B. too much thinking
C. tons of working time D. frequent revisions
2.What do writers do in the course of creating a novel?
A. They spend every minute with the novel. B. They treat the novel as a lover.
C. They go out with some readers for dinner. D. They hurt themselves to stay awake.
3.By “breathing down its literary neck” in Paragraph 2, the author most probably means _____.
A. writing casually thus failing to take readers’ breath away
B. letting go a single mistake thus annoying the readers
C. X-raying the work thus finding each literary mistake
D. sticking too close to the work thus causing anxiety
4.Which of the following is most likely to come after the last paragraph?
A. The importance of using proper transitional words in writing.
B. The writing experience shared by famous successful write.
C. Tips on how to make ten drafts to complete a good novel.
D. Setbacks writers may suffer if ignoring the craft advice.

[1]Traveling overseas to a foreign country can be an amazing experience. However, for those who are not prepared to take part in a new culture, they may be totally overwhelmed by having to go through this unfamiliar chain of events. This phenomenon is called culture shock, and often occurs when people visit a country for which they are not ready. One can avoid embarrassment and enjoy the trip more if they have taken preparations against such "shock" in the first place.
[2] First off, one must remember to prepare themselves through education for their visit. Do not just show up in some country like Mongolia with no idea about what to expect even in the least. Instead, take some time to read, research, and look up information on the specific country you are traveling to, either through the use of a library or a bookstore, or through the Internet.
[3] Secondly, ________. Many times these people can answer questions you may have about the country, especially ones you may not have answers to from the research you have done online or in print. Firsthand experience is extremely valuable and having someone you can trust to talk about their experience in a certain country is very important.
[4] Lastly, after you have done everything you can do to prepare, you are on your way to your destination, remember to be very, very flexible, and be polite. It is so important to be flexible in your travel, which really helps in breaking down any culture shock on might experience. Keep these tips in mind, and be open in your travel experiences.
