Anyone, once _______ positive for H7N9 flu virus, will receive free medical treatment from our government.

A. to be tested                 B. being tested                 C. tested                           D. to test

 

【答案】

C

【解析】

试题分析:句意:任何人一旦检测H7N9流感病毒为阳性,将会接受我们政府的免费医疗服务。此处once后是省略句,完整的是once anyone is positive for H7N9 flu virus,这里把从句放在了句中,从句省略的条件是从句的主语与主句的主语是一致的,并且从句的谓语动词有be动词,这时把从句的be动词与主语一起省略,故选C。

考点:考查省略的用法。

I found another cell phone a few years back, too, and called a number in its phone book.I explained the situation to the guy who answered.He said it was his sister’s and that he’d come to pick it up, which he did.

B
It was a beautiful Sunday morning, and Maggie and I were returning from our walk through the woods. We were only a couple of blocks from home when I spotted a cellphone and credit card sitting on the road. We took them home. We find amazing things on the street. She looks upon it as a movable dinner. Chicken wings here and there.
I found another cellphone a few years back, too, and called a number in its phone book. I explained the situation to the guy who answered. He said it was his sister’s and that he'd swing by to pick it up, which he did.
And that was that. No verbal (口头的) thank-you, no written thank-you, no “here’s a box of chocolates” thank-you.
I didn’t have time to call anyone on my latest found cellphone. I was pouring myself coffee when it started to vibrate (颤动) and dance across the kitchen counter.
“Who’s this?” someone asked when I picked up.
“Who’s this?” I countered. “Sarah?”
She was taken aback until she realized her name was on the credit card I also had recovered. “Could you send it to me?” she asked.
She lives in Arlington, which is 2 miles from my house.
“Hmm, no,” I replied, adding that I thought she could come get them, and that if I wasn’t home, they would be in my mailbox.
A day later, when I was out for a run, someone retrieved them. But I got nothing. In this age of e-mail and cellphones, there’s really no excuse.
Years ago, I found something more precious than a $100 bill on the street: a driver’s license. I saw that its owner lived a couple of blocks from me, so I called him up. He asked whether I could slip the license through his front door.
“I guess I could,” I replied.
And that was that.

MySpace, the social networking website, is different from other websites which only provide stories about other people. MySpace is a place that allows you to broadcast your own stories and personal information to as many people as you like. Started two years ago, it is a big source of information for and about American kids.
Teenagers and their parents feel very differently about it. Teens are rushing to join the site, not sharing their parents' worries. It signals yet another generation gap in the digital era.(数字时代)
For teenagers, it is reliable network to keep in touch with their friends. They will often list their surnames, birthdays, after­school jobs, school clubs, hobbies and other personal information.
“MySpace is an easy way to reach just about everyone. I don't have all the phone numbers of all my acquaintances (熟人). But if I want to get in touch with one of them, I could just leave them a message on MySpace.” said Abby Van Wassen. She is a sixteen ­year­ old student at Woodland Hills High of Pittsburgh, Pennsylvania.
Parents on the other hand are seriously concerned about the security problems of MySpace.
“Every time we hold a parents meeting, the first question is always about MySpace,” said Kent Gates, who travels the country doing Internet safety seminars (研讨会).The National Center for Missing and Exploited Children has received at least 288 MySpace­ related complaints, according to Mary Beth Buchanan, a lawyer in Pittsburgh.
“Your profile on MySpace shows all your personal information to anyone on the Web. And MySpace even lists this information by birthplace and age. It's like a free checklist(清单)for troublemakers and it endangers children,” Buchanan said.
【小题1】From the passage we can learn that MySpace ________.

A.brings about the generation gap
B.is very careful about people's privacy
C.encourages you to list your personal information
D.lists the telephone numbers of your friends
【小题2】Why are some parents against MySpace?
A.Because MySpace has a bad influence on their children.
B.Because they don't want to pay so much money for MySpace.
C.Because it takes up too much of their children's spare time.
D.Because troublemakers can easily approach their children through the site.
【小题3】The writer's attitude towards MySpace is ________.
A.negativeB.positiveC.optimisticD.objective
【小题4】Which of the following can be the best title of the passage?
A.Internet safetyB.MySpaceC.Generation gapD.The digital era

Below are some smart ways to stay healthy suggested by some American experts.

Drink More Coffee

When was the last time you heard a doctor use the word miracle? Well, wake up and smell the coffee: “It’s amazing,” says liver specialist Sanjiv Chopra, MD, professor of medicine at Harvard Medical School. “Coffee is truly a lifesaving miracle drug.”

Though he says it’s still a “scientific mystery” how a simple cup of coffee works its wonders in the body, large epidemiological studies have repeatedly proved its astonishing benefits.

“Drink it black, or at most put a little skim milk in it” to minimize calories, Dr. Chopra recommends. He drinks at least four cups a day himself, though most people should limit themselves to two. And no, he jokes, “I’m not sponsored by Starbucks.”

Take a Walk for Your Memory

Aerobic (有氧运动的) exercise is good for your body, great for your mind, according to the latest research from brain-fitness pioneer Arthur Kramer. Every year, an area called the hippocampus, which is key to memory, shrinks by about 1 to 2 percent, increasing the risk of dementia (脑衰) as the years roll by. However, Kramer’s new investigations reveal that the hippocampi of adults who walked briskly for about 45 minutes three times a week grew by about 2 percent over the course of a year, preventing age-related shrinking.

It’s never too late to start exercising, Kramer says; volunteers in his research were between 55 and 80 years old and hadn’t exercised at all. And it doesn’t need to be backbreaking. “Anything that raises your heart rate seems to work,” he says. “Walking is fine. Just find something you like and do it.”

Early to Bed, Early to Eat

“Being a night owl might increase your waistline,” says sleep expert Michael Breus, PhD. People who stay up late and sleep late tend to eat more fast food and consume more of their calories after 8 p.m. than do normal sleepers.

“One of the easiest things that anyone on a diet can do to improve her results is go to bed and wake up at the same times every day,” Breus says. “This way, your body knows when to sleep and is much more efficient. Organize your eating, too, by trying to eat meals at the same times every day. Avoid eating after 8 p.m., and don’t miss morning meals by sleeping in.”

Use the 20-Second Rule

What’s the difference between having a goal and actually accomplishing it? Just 20 seconds, says positive-psychology specialist Shawn Achor. Researchers have learned that if we can cut 20 seconds off the startup time required for a task, we’re much more likely to follow through. So, for example, if you want to work out in the morning, place your shoes and exercise clothes next to your bed the night before. If you want to praise people more, put thank-you notes and a pen on your desk.

Imagine the Worst to Feel Better

Don’t count your blessings; subtract (扣除) them. “Consciously spend a few minutes imagining what your life would be like without the good things,” says Timothy Wilson, a psychologist at the University of Virginia. You’ll experience stronger feelings of love, gratitude, and happiness when you think about what life would be like without the people and things you love. “And they’ll seem surprising and special again,” he adds.

1. According to Sanjiv Chopra, most people should not drink more than ______ cups of coffee a day.

A. two????????????? B. three????????????? C. four????????????? D. six

2.Which of the following may help people on a diet to improve their results?

A. Raising their heart rate.????????????? B. Taking a walk for their memory.

C. Eating at fixed times.????????????? D. Sleeping in every morning.

3.According to Shawn Achor, if people place their shoes and exercise clothes next to their bed at bedtime, they’re more likely to ______ the next morning.

A. do exercise????????????? ????????????? ????????????? B. set a goal?????????????

C. cut 20 seconds off????????????? D. sleep 20 minutes more

4. Why should people spend a little time imagining their life without good things?

A. To experience surprise.????????????? B. To feel better.?????????????

C. To consider their own blessings.????????????? D. To prepare for the worst.
