Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate(桂冠). As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi.

Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career.

Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations.

Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them.

Aided by computers, Hoffmann was able to generate a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value.

1.What can be inferred from the above passage about Hoffman?

A. He left his homeland when he got the Nobel Prize.

B. He went to the United States to gain his Nobel Prize.

C. He might find the Unites States a better place to learn chemistry.

D. His family may have settled in the United States.

2.How did Hoffman make his research popular?

A. He applied some computer skills to help explain his ideas.

B. He established a special computer system to help.

C. He drew some forms explaining his ideas.

D. He did series of experiments to prove his ideas.

3.The underlined word “generate” in this passage might most probably mean “______”.

A. bring in B. break down

B. move away D. keep secret

4.Why was Ronald Hoffman awarded the 1981 Nobel Prize for chemistry?

A. He established rules to predict chemical reactions .

B. He succeeded applying computer science to chemistry research.

C. He shared what he had achieved with another scientist named Fukui Kenichi.

D. He succeeded in both chemistry and computer researches.

One night in February 1962, John H. Glenn. Jr., flew over Australia. The man in the Mercury(水星) capsule（宇宙飛行容器）was alone, but friendly voices reached him by radio. On the dark land 100 miles below, he saw a sprinkling of light. They marked the city of Perth, where people had turned on their lights as a greeting to him.

In Friendship7, Glenn radioed, “ The lights show up very well. Thank for everybody for turning them on.” His capsule raced on to the east.

During his three orbits（繞……軌道而行） of the earth, Glenn could always reach one of eighteen tracking stations. Some of them were on ship at sea. Others were in the United States.

Many of the stations had been built with the help of other countries. These countries allowed Americans to bring in radio equipment and set it up. Without the help of such lands as Nigeria（尼日利亞）, Zanzibar（尚巴西，坦桑尼亞領(lǐng)土的一部分）, and Mexico, there would have been breaks in the worldwide radio network.

John H. Glenn. Jr., was the first America to orbit the earth. For his flight, the tracking network（跟蹤網(wǎng)絡(luò)） covered 60,000 route miles. Five hundred men worked in the stations along the route. Since his flight, the network has grown. Today, it covers more than 100,000 route miles and has about one hundred stations. One-third of these stations are outside of the United States.

Last Sunday morning, where I was having a walk in the park near my home, I came across many people make a new film with one of my favorite actor. I didn’t have my camera with me at that time, but I rushed back home to get one. Unfortunately, by the time I got back, they had finished the scene and the actor couldn’t be seen everywhere. I was really disappointing and about to leave when he walked out a building. He was right there in the front of me! I couldn’t believe my luck——not only did I had my photo taken with him, but he signed his name on my shirt!

My heart sank when the man at the immigration counter gestured to the back room. I was born and raised in America, and this was Miami, where I live, but they weren’t quite ready to let me in yet.

“Please wait in here, Ms Abujaber,” the immigration officer said. My husband, with his very American last name, accompanied me. He was getting used to this. The same thing had happened recently in Canada when I’d flown to Montreal to speak at a book event. That time they held me for 45 minutes. Today we were returning from a literary festival in Jamaica, and I was startled that I was being sent “in back” once again.

The officer behind the counter called me up and said, “Miss, your name looks like the name of someone who’s on our wanted list. We’re going to have to check you out with Washington.”

“How long will it take?”

“Hard to say ... a few minutes,” he said. “We’ll call you when we’re ready for you.” After an hour, Washington still hadn’t decided anything about me. “Isn’t this computerized?”

I asked at the counter. “Can’t you just look me up?”

Just a few more minutes, they assured me.

After an hour and a half, I pulled my cell phone out to call the friends I was supposed to meet that evening. An officer rushed over. “No phones!” he said. “For all we know you could be calling a terrorist cell and giving them information.”

“I’m just a university professor,” I said. My voice came out in a squeak.

“Of course you are. And we take people like you out of here in leg irons every day.”

I put my phone away.

My husband and I were getting hungry and tired. Whole families had been brought into the waiting room, and the place was packed with excitable children, exhausted parents, even a flight attendant.

I wanted to scream, to jump on a chair and shout: “I’m an American citizen; a novelist; I probably teach English literature to your children.” Or would that all be counted against me?

After two hours in detention, I was approached by one of the officers. “You’re free to go,” he said. No explanation or apologies. For a moment, neither of us moved, we were still in shock.

Then we leaped to our feet.

“Oh, one more thing.” He handed me a tattered photocopy with an address on it. “If you weren’t happy with your treatment, you can write to this agency.”

“Will they respond?” I asked.

“I don’t know --- I don’t know of anyone who’s ever written to them before.” Then he added, “By the way, this will probably keep happening each time you travel internationally.”

“What can I do to keep it from happening again?”

He smiled the empty smile we’d seen all day. “Absolutely nothing.”

After telling several friends about our ordeal, probably the most frequent advice I’ve heard in response is to change my name. Twenty years ago, my own graduate school writing professor advised me to write under a pen name so that publishers wouldn’t stick me in what he called “the ethnic ghetto” --- a separate, secondary shelf in the bookstore. But a name is an integral part of anyone’s personal and professional identity -just like the town you’re born in and the place where you’re raised.

Like my father, I’ll keep the name, but my airport experience has given me a whole new perspective on what diversity and tolerance are supposed to mean. I had no idea that being an American would ever be this hard.

1.The author was held at the airport because __________.

A. she and her husband returned from Jamaica.

B. her name was similar to a terrorist’s.

C. she had been held in Montreal.

D. she had spoken at a book event.

2.We learn from the passage that the author would __________ to prevent similar experience from happening again.

A. write to the agency B. change her name

C. avoid traveling abroad D. do nothing

3.Her experiences indicate that there still exists __________ in the US.

A. hatred B. discrimination

C. tolerance D. diversity

4.The author sounds __________ in the last paragraph.

A. impatient B. bitter C. worried D. ironic
