Though he wore his whiskers (颊须) only four years, today we can hardly think of Abraham Lincoln without them. He often talked about the little girl in Westfield, New York, who suggested in a letter that he grow the famous whiskers. And he would add, “Sometimes a small thing can change our lives!”
Grace Bedell sat in her room looking at a picture of Lincoln. Her little lamp threw shadows on the picture. A frame (框) of small shadows lay around the thin face and covered the hollow cheeks (面颊). “Whiskers!” she thought.
“How nice!” she said to herself. “There will be more people to elect him President if he lets his whiskers grow. Somebody ought to tell him.” She reached for a pen and began to write the letter.
On February 16 of the following year a special train carried the newly elected President Lincoln to the White House. The train stopped briefly at a station near Grace’s town. At the station Lincoln was speaking to a large crowd, among whom were the Bedell family.
Lincoln continued his speech, “I have a little friend in this place,” he said. “That little lady told me how to improve my appearance, and I want to thank her. If she is present, I would like to speak to her. Her name is Grace Bedell.”
Grace’s father led her forward to Lincoln. She looked and laughed happily, for up there on his face were the whiskers.
If you visit Springfield, Illinois, today you will see the house in which Abraham Lincoln used to live. On the wall of a room hangs a piece of paper covered with a child’s handwriting: “Dear sir...”

Plants are flowering faster than scientists predicted（预测）in reaction to climate change, which could have long damaging effects on food chains and ecosystems.
Global warming is having a great effect on hundreds of plant and animal species around the world, changing some living patterns, scientists say.
Increased carbon dioxide（CO2）in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.
“Predicting species’ reaction to climate change is a major challenge in ecology,” said the researches of several U.S. universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated（低估）the speed of flowering by 8.5 times and leafing by 4 times.
“Across all species, the experiments under-predicted the speed of the advance — for both leafing and flowering — that results from temperature increases,” the study said.
The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.
Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis（光合作用）to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world’s average temperature has risen by about 0.8℃ since 1900, and nearly 0.2℃ every ten years since 1979.
So far, efforts to cut emissions（排放）of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃ this century — a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.
【小题1】What is the key information the author wants to give in Paragraph 1?

Most people think that the capital of the movie world is Hollyhood, in the United States. However, the real movie capital is Mumbai, in India. Mumbai used to be known as Bombay, and so the film industry there is called “Bollywood.” Bollywood makes twice as many movies each year as Hollyhood—more than 800 films a year.
The movies from Bollywood are very different from Hollywood movies. For one thing, Bollywood movies are much longer than most Hollywood movies. Most Bollywood movies are more than three hours long, and contain singing, dancing, action, adventure, mystery, and romance (but usually no kissing). Because Bollywood films contain so many different features, this style of film is sometimes called a “masala” film. (“Masala” is an Indian word for a mixture of spices.)
Another big difference between Bollywood and Hollywood movies is the way movies are made. It takes much longer to make a movie in Hollywood than in Bollywood. In fact, filming may begin on a Bollywood movie before the script even finished. The director and writers can make up the story while the film is being made. Sometimes they will even write the script by hand instead of taking time to type it.
Bollywood actors are very popular and some are in such high demand that they may work on several movies at the same time. They may even shoot scenes for several films on the same day using the same costumes and scenery. Since most Bollywood movies follow the same kind of story, shooting scenes for several films at the same time is not a big problem for actors or directors. This also helps keep the cost of Bollywood movies lower than the cost of Hollywood movies. The average Bollywood film, with a budget of only two million U.S. dollars, seems very cheap compared to the average budget of sixty million U.S. dollars for a Hollywood film—thirty times as much!
