Direction: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.

Apple’s iPhone may be big news, but in Silicon Valley all eyes are on Facebook. The all-age private Internet club that began as a college student hangout has become the technology industry’s hottest ticket.

Facebook, which started out offering simple Web profile pages for users to update personal details and link to their friends, has since late May provided an easy way to enhance profiles with growing menu of 1,400 applications from virtual horoscopes to music video players.

Membership has exploded to over 29 million active users, up one million users in just the past week and five million from six weeks ago. It’s adding more than 150,000 member a day, up from its pace of 100,000 six weeks ago, Facebook says.

Facebook has become the central way many users keep track of Web sites they use every day. More importantly, it’s a way to keep up with what friends are doing, says Chief Technology Officer Adam Angelo, a high school classmate of Zuckerberg.

Far bigger rival MySpace has difficulty striking a balance between sharing personal data and not revealing “too much information”. Many Facebook users post their mobile phone numbers, political affiliations or changes in dating status.

“Facebook is not open the way the Web is open, Users share all kinds of information on the site they would never share on the Web,” Angelo, 22, says. “We get users to reveal more information because we protect users’ privacy.

One protest group, called “Facebook Should Be Students ONLY”, with 20,000 members, is magnet from random discontent.

“Facebook should most definitely be ONLY students,” Katerina Laurel, 15, of Kansas City, Kansas, writes in Web shorthand. “Our CHOIR teacher has a Face book membership.”

Laurel’s solution is to use the site’s privacy controls to exclude the teachers/principals/dens/choir directors in her life. “I can just block them from my site if I don’t want them to see any of my profile.” She says.

（Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.）

1.What is Facebook?

科目：高中英語(yǔ) 來(lái)源：2013-2014學(xué)年福建省高三第二次月考英語(yǔ)試卷（解析版） 題型：閱讀理解

We each have a unique genetic(基因的, 遺傳的)make-up. Every cell of our body has the same set of about 100, 000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of our skin to the way our brain works. We have one of several billion combinations of DNA which come from the random mixing of our parents’ genes. Except for identical twins(同卵雙胞胎), no one has the same combination as another person. We are unique! We are unique in another way, too: in the way we are raised and all the experiences we have from before birth to adult life. These experiences influence us, our behaviour and attitudes, and the choices we make.

But are genes or life experiences more important in shaping our appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births—some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters.

Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit(繼承). For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins.

Scientists are trying to identify the different genes that influence our behavior. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.

We could ask, “Are our lives determined by our genes or our upbringing? ”Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.

1.What is the main idea of the first paragraph?

A. Both our genes and our experiences make us who we are.

B. How we turn out depends on our parents’ genes.

C. Everyone has a physical double somewhere in the world.

D. We cannot easily change our physical appearance.

2.Why are scientists studying twins?

A. To find out how many twins are born every year.

B. To discover what shapes us as individuals.

C. To compare differences between twins.

D. To study brother-and-sister relationships.

3. According to the passage, .

A. one in 70 twins are genetically identical

B. non-identical twins are usually not of the same sex

C. twins separated at birth behave exactly the same

D. identical twins are genetically the same

4.What does the underlined word “this” in Paragraph 4 refer to?

A. Our love of sports. B. Our attitude to risk-taking.

C. Our skill at bungee jumping. D. Our ability to take drugs.

科目：高中英語(yǔ) 來(lái)源：2013-2014學(xué)年浙江東陽(yáng)中學(xué)高三下期中英語(yǔ)試卷（解析版） 題型：閱讀理解

My parents have certainly had their troubles, and as their child I’ll never know how they made it to 38 years of marriage. They loved each other, but they didn’t seem to like each other very much. Dad was too fond of his beer, and he talked down to Mom a lot. When she tried to stand up to him, a fight would unavoidably follow.

It was my dad’s disease that began to change things. The year 1998 was the beginning of a remarkable transformation for my family. My father, Jim Dineen, the always healthy, weightlifting, never-missed-a-day-of-work kind of dad, discovered he had kidney (腎) disease.

The decision to go ahead with a transplant for my father was a long and tough one, mostly because he had liver damage too. One physician’s assistant told him, “According to your file, you’re supposed to be dead.” And for a while, doctors mistakenly thought that he would need not just a kidney transplant, but a liver transplant too. Dad’s future hung in midpoint.

When the donor testing process finally began in the spring of 2003, numerous people, including me, my uncle Tom, and my mom, came back as matches of varying degree. But Mom was the one who insisted on going further. She decided to donate a kidney to my father. She said she was not scared, and it was the right thing to do. We all stepped back in amazement.

At last a date was chosen – November 11, 2003. All of a sudden, the only thing that seemed to matter Dad was telling the world what a wonderful thing Mom was doing for him. A month before the surgery, he sent her birthday flowers with a note that read, “I love you and I love your kidney! Thank you!”

Financially, the disease was upsetting to them. So my sister and I were humbled and surprised when, shortly before his surgery day, Dad handed us a diamond jewelry that we were to give to Mom after the operation. He’d accumulated(積累) his spare dollars to buy it.

At the hospital on the day of the transplant, all our relatives and friends gathered in the waiting room and became involved in a mean euchre (尤克牌游戲) tournament. My family has always handled things with a lot of laughter, and even though we were all tense, everybody was taking bets on how long this “change of conduct” would last in my parents.

We would inform Dad that if he chose to act like a real pain on any particular day after the operation, he wasn’t allowed to blame it on PMS just because he’d now have a female kidney.

The surgeries went well, and not long afterward, my sister and I were allowed to go in to visit. Dad was in a great deal of pain but again, all he could talk about was Mom. Was she okay? How was she feeling? Then the nurses let us do something unconventional. As they were wheeling Mom out of recovery room, they rolled her into a separate position to visit Dad. It was strange to see both my parents hooked up to IVs and machines and trying to talk to each other through tears. The nurses allowed us to present the diamond jewelry to Mom so that Dad could watch her open it. Everyone was crying, even the nurses.

As I stood with digital camera in hand, I tried to keep the presence of mind to document the moment. My dad was having a hard time fighting back emotion, and suddenly my parents unexpectedly reached out to hold each other’s hands.

In my nearly 35 years of existence, I’d never seen my parents do that, and I was spellbound. I snapped a picture and later rushed home to make sure I’d captured that enormous, life-defining moment. After so many years of disagreement, it was apparent to me that they finally understood how much each loved the other.

1.From the first paragraph we can learn that _________.

A. Dad was fond of drinking

B. My parents got along well

C. Dad often beat Mom

D. Mom never obeyed Dad

A. Dad's life journey was on half way

A. Worried and negative.

B. Anxious and helpless.

C. Nervous but optimistic.

D. Relaxed and positive.

B. Dad asked the nurse to visit Mom soon after the operation.

C. Despite a lot of pain, Dad was eager to know Mom’s condition soon after the operation.

D. On the day of the transplant, the families involved in a mean euchre tournament to relax themselves.

C. Dad watched Mom opening the gift.

D. His parents were holding each other’s hands.

6.What’s the best title for the passage?
