I still remember my first job in the city center. The        was large, dark and old        the physics lecture room was on the second floor.        , it wasn’t a lecture room at all, it was an ordinary room, but it had “LECTURE ROOM’ on the       . The students were sixteen or seventeen years old,        several years younger than me.       , some of them looked and acted       older than me sometimes.

The room was directly       the street, and had the window looking out over the street and many houses. One day, I was       some words on the blackboard when I heard a sudden change in the noise behind me. There was a man standing in the room with       an apple in his hand. He looked      .

“Who threw this?” he asked, looking round the class.

“I beg your pardon? What is the matter?” I said. “      threw this apple out of the window,” he said. “It       on my car.”

 “Who threw an apple out of the window?” I       to the class. There was no answer.

“I       the fellow who threw this.” said the man. “I will be       outside for you.” And then he left, closing the door behind him.

      was silence and I continued with the lesson. At the end of every lesson, usually the class were all       before the bell finished ringing, leaving me saying “That’s all for today” to an empty     .  This time, when the bell went for the end of the lesson, no one      .  “That’s all for today,” I said. “You go first, sir,” said one of the boys. It made a nice change, I being out first.

WASHINGTON—US President Barack Obama said Thursday that he had known about NBA star Jeremy Lin’s talent long before the“Linsanity”phenomenon swept the sport.

“I knew about Jeremy before you did because Arne Duncan, my secretary of education, was captain of the Harvard team,”Obama told the famous US sportswriter Bill Simmons in an interview.

“When Arne and I were playing, he said,‘I’m telling you, we’ve got this terrific guard named Jeremy Lin at Harvard.’And then when one of my best friends, whose son is a freshman at Harvard, went for a recruiting(招募) trip he saw Lin in action, so I’ve been on the Jeremy Lin bandwagon(时尚) for a while,”said the president, who is a Harvard Law graduate.

Lin, the New York Knicks’ point guard, though he was cut twice in December 2011, had had a sudden rise in the past month to high points scoring stardom in Madison Square Garden, the world’s biggest basketball stage.

He is the first Chinese-American player in the NBA. He has already developed a devoted following among many Asian-Americans and in China, Taiwan, the Philippines and other countries.

Clicks to the NYKnicks. Com website surged as basketball fans from around the world search for Lin’s news and highlights.

“He seems like a wonderful young man. It elevates(提升) this great sport all round the world,”said Obama, a Chicago Bulls fan.“And what’s been encouraging is to see how fast the sport has bounced back(恢复) recently.”But he sounded a note of caution on how much basketball costs to watch.

“It’s really important for professional athletes and sports owners to just remember you got a whole bunch of folks out here, all across the country, who invest so much in their teams. All they ask is not to be so selfish that you’re not looking out for your fans,”Obama said.

1.President Obama learned about Jeremy long before through      .

2.The underlined word“surged”in Paragraph 6 probably means     .

3.President Obama finds it encouraging that      .

4.Both athletes and sports owners should care about folks because      .

They say that Mexico is a country no one ever leaves. Every year, millions of tourists pass through. And Mexicans happily warn that a part of them will remain behind forever. Most visitors are vacationing North Americans who go up on the brilliant beaches of Cancun, Acapulco, Mazatlan, and Puerto Vallarta. The beaches, of course, are among the world’s best ----but those who venture (冒险) inland are rewarded with the true soul of Mexico.

And it is a big soul. The Republic of Mexico is vast, consisting of nearly two million square miles of coastline, desert, rain forest, mountains, and rich plains. From the American borderlands of the wide, agriculturally rich north, the country narrows gently as it sweeps south and east. The two main mountain ranges(山脊), the Sierra Madre Occidental and the Sierra Madre Oriental, hug the west and east, finally merging（融入） into the volcanically active central highlands and the capital, Mexico City - the most populous city in the world. Further south, the country narrows to only 100 miles, then broadens again before reaching the Guatemalan border. There are two major peninsulas (半岛) in Mexico: the Baja Peninsula to the west and the Yucatan peninsular to the east.

The population is about 106 million. and the generosity (慷慨大方) of the Mexican people is unsurpassed. Knowing a few simple sentences in Spanish will win hearts.

Mexico has been blessed with an unusually temperate (适度的) climate year-round. The most important thing to remember is that the Mexican summer is also the rainy season, although the rain rarely lasts more than a few hours, and typically arrives in the late afternoon. Extremes(极端)are present only in the North and in Baja, both of which have deserts where the temperature leaps above 100F. Mexico City has a year-round temperature in the high 80s. while the coasts usually stay in the mid-90s. Night time temperatures fall somewhat, but rarely break down below a comfortable 60F.
