根据短文内容回答下列问题。

    My father used to work in the city and seldom stayed at home. But he would come back and help to harvest(收割) rice every year.

    One autumn, he promised to help our neighbour, who lost his arms in a traffic accident in 1999, to harvest his rice. After father harvested our own, his little rice picker broke. What's worse, he had to return to work the next day because his partner was ill in hospital. It meant that father wouldn't be back in a few days. It now seemed impossible to help out the neighbour.

    Father told us that he wouldn't let the neighbour's rice rot(腐烂) in the field. He decided to harvest it by hand without a machine. "If tonight's weather is clear, I think I can do it, "added my father. In fact, he was rather tired after a day's harvest work.

    After dinner, father had a short rest and made his way to the field. A full moon was glowing(发光) in the sky and the weather was cold but clear. He spent the whole night keeping his word.

    I would never forget the image(画面): Father was cutting rice in the light of the harvest moon. Behind him, row after row of rice stocks(秸秆) stood at attention, showing respect for a man who kept his word.

    How would you persuade (劝说) your parents to support your dream? American actress Emma Stone created a PowerPoint presentation (陈述) to get her argument across.

    Stone is a rising star in Hollywood. She has played the role of Gwen Stacy, Spider-Man's high school love interest, in two Spider-Man movies.

The actress said she has something in common with her character in the film. "Gwen is clear on what she wants to do with her life... I think I am in the same ballpark (同一范围) there."

    Stone made up her mind to become an actress at the age of 15. But would her parents agree to her leaving school early and pursuing (追求) her dream? The young girl decided to think outside of the box.

    "I used a lot of computers when I was younger, and my dad's a businessman, so I just thought a presentation is the way to get my point across," she said.

She titled the presentation Project Hollywood and used pop singer Madonna's classic song Hollywood as the soundtrack, saying "just please let me move to LA to be an actress."

    Her tactic (策略) proved to be a success. In 2004, Stone dropped out of high school and moved with her mother to Los Angeles. She was homeschooled after that.

Now Stone is a successful actress with many films to her name. Her next step is to try different things like "bizarre (奇怪的)" characters or comedy. Will she persuade directors with PowerPoint presentations too?

    Answer the following questions:

    Rainforests are magical(神奇的)places on earth, full of life and beauty. They are homes, to millions of birds, insects, animals, and plants. These forests are the world's natural treasure(财富).

    Most rainforests are near the equator(赤道). Some of the largest are in Brazil, South Asia and Central Africa. There are several kinds. Each has different levels of rainfall and different types of soil and temperature.

    In equatorial rainforests, the temperature stays between 25 and 35 degrees during the year. These rainforests get a lot of rain-as much as 4, 000 millimeters per year. Monsoon rainforests are very different. They have long dry periods. Also, their temperature can change a lot from season to season.

    Rainforests are important for many reasons. One is their great diversity(多样性)of life. There are millions of species of insects, animals, and plants. Scientists still don't know about most of them yet. Many rainforest plants could help us make new medicines. Rainforests also keep the soil strong. And they may be important to the earth's climate.

    Unfortunately, rainforests are getting smaller every year. Farmers burn down trees for land. Large companies cut down trees for their valuable wood. Other companies build mines near forests.

    Environmental groups are trying hard to save the rainforests. Hopefully they can, before they're all gone.
