While Jennifer was at home taking an online exam for her business law class, a monitor(监控器) a few hundred miles away was watching her every move.

Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked---remotely---to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was; Did she enter her student number at the same speed as she had in the past? Or was she slowing down?

In the battle against cheating, this is the cutting edge and a key to encourage honestly in the booming field of on line education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid---that students haven’t searched the Internet to get the right answers.

Although online classes have existed for more than a decade, the concern over cheating become sharper in the last year with the growth of “open online courses.” Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.

Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check student’s identities using personas information, such as the telephone numbers they once used.

Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.

1. Why was Jennifer watched in an online exam?

A. To correct her typing mistakes.

B. To find her secrets in the room.

C. To keep her from dishonest behaviors.

D. To prevent her from slowing down.

2.The underlined expression cutting edge in Paragraph 3 is closest in meaning to _____.

A. sharpening tool   B. advanced technique

C. effective rule   D. dividing line

3. Some programs can find out possible cheaters by_________.

A. checking the question answering speed

B. producing a large number of questions

C. scanning the Internet test questions

D. giving difficult test questions

I clearly remember the day when my little brother was born: January 1, 1994. One of my favorite family photos shows me lying with my mother in the hospital bed, happy but un-aware of the small, sleeping baby in the background.

I stayed with my grandparents for the weekend of my brother’s birth, excited about my new brother but not yet aware of what having a little brother would mean. I didn’t truly realize what was going on until we were in the hospital room at Duke University----

coincidentally (碰巧地), the same room in which I had been born two years earlier.

When I looked at my brother for the first time, I felt a mixture of fear and interest. Little did know that small, pink creature would grow up to be one of my favorite people in the world.

In reality, though I am two years older than my brother, I am more often than not the real baby in the family. I am very lacking when it comes to common sense. Instructions constantly confuse me and I frequently find myself totally puzzled by things like knowing how to start the washing machine or manage the storage settings on my iPhone.

That’s where Gibson comes in. The poor kid has had to guide me through more tasks than I would care to admit, but he never complains. Though I should probably be told to figure it out myself, he always comes through.

I’m envious of his ability to readily answer the ever-present, “What do you want to do with your life?” question at family gatherings. “Be a doctor,” he says----a solid answer, completely opposite to my shaky one, “Well, I’m an English major, so...”

My brother truly is my best friend. No one understands me better, and there isn’t anyone else I would want to be stuck with in our family. I may not have a clear idea of where I’m headed, but he is stuck with me.

1.How did the author feel when he saw his brother for the first time?

A. Angry and sad.

B. Excited and moved.

C. Curious and scared.

D. Happy and interested.

2.What does the underlined sentence in the fourth paragraph mean?

A. My brother is the real baby in the family.

B. In fact, I seem to be less mature than my little brother.

C. My brother gets more love from the family than I do.

D. I am growing more slowly than my brother.

3.What does the brother often help the author do?

A. Help him deal with many daily tasks.

B. Help him with his studies.

C. Give him advice on how to choose a major.

D. Comfort him when he is in a bad mood.

4.What is the best title for this text?

A. My Strange Family Gatherings

B. The Real Baby in the Family

C. Stuck with Me----My Not-So-Little Little Brother

D. The Feeling of Having a Brother

I took a trip to a big lake in Indonesia with my family two years before. It was really huge lake with beautiful scenery all around. People were amazed by the endless view in front of our eye. Later on, unlike other girls, I was volunteered to go waterskiing alone. I took on the life jacket, got off the motorboat immediately and started my engine as soon as possibly.

The lake seemed broad and endless. I was so exciting to appreciate the beauty of the mountains and waters that I speed my motorboat. Then, after some time, I found me in the middle of the endless lake. I really enjoyed the unforgettable experience!
