Dear fellow students,

Dear fellow students, let's take action right now!

2 . We all know that forests-especially rainforests-absorb carbon dioxide and produce the oxygen that all living things depend on. It’s no wonder that they have been named the lungs of the planet. Today, after the big fires in the Amazon, Alaska, Greenland, and even Siberia, it’s very clear that we need to grow a forest that is fireproof. That’s not an impossible dream. We can grow seaweed forests that are fireproof because they are underwater.

Seaweed can store carbon and help reduce the influence of global warming. Now, seaweed is being farmed in small ocean farms to be used for food, medicines, and beauty products. If seaweed can be grown on a large scale(大规模地), it could help to fight against global warming.

“Seaweed is finally having its moment in the spotlight,” said Halley Froehlich, a scientist at the University of California. She is the lead author of a new study published in Current Biology. The study shows that large-scale seaweed farming could be used to cancel out land-based carbon emissions and it mapped the areas of the oceans where seaweed could be grown.

Now, only 3.8 percent of the US waters off the coast of California are being used to grow seaweed but that is just 0.065 of the ocean that can be farmed. In fact, 48 square kilometers of the world’s oceans can be used for seaweed farming.

For seaweed farms to be part of the global solution, they will have to be much larger. To create underwater forests, seaweed would have to be grown, harvested and then sunk into the deep ocean so that the trapped carbon could be buried for years to come.

While it sounds like a good plan on paper, “The technology doesn’t yet exist” to keep seaweed in the deep ocean, said Froehlich. “Hopefully this paper encourages conversation among engineers and economists about what it would take for the actual tools to be put in place.”

C．It needs lots of money to carry out.	D．It needs enough evidence to support.

3 . Jane Goodall is best known for her 26-year study of the chimps in the wild. There, she made several revolutionary discoveries that made her one of the greatest field scientists of the 20th century.

Born in London in 1934, the expectations for Jane were standard for the time: a marriage to a nice man, followed by a few children. Fortunately, her mother never discouraged (劝阻, 使气馁) her interests: animals and the natural world. Once her mother discovered that little Jane had brought a handful of worms (幼虫) to bed; rather than screaming, she explained that her new little friends needed the soil to live, and together, they took them back to the garden.

Jane was a bookworm who admired Doctor Dolittle and loved the Tarzan novels. Reading did its usual quiet but life-changing thing: Jane developed a dream to go to Africa and live among the wild animals.

Jane realized her dream on July 14, 1960 when she arrived at Gombe Stream Game Reserve to study the chimps. However, for two months, the chimps escaped when they heard her coming. The only thing she saw was the back of a chimp，running away from her.

“The more I thought of the task I had set myself, the more discouraged I became,” Jane wrote in her first book, In the Shadow of Man.

Eventually, she became familiar with a male chimp and his big family. She observed them kiss, hug, pat each other on the back, shake their fingers at each other. She watched them act very human-like.

One day, moving quietly through the jungle, Jane saw the male chimp sit beside a large termite mound (白蚁土堆). He kept taking small braches from trees and putting them in the holes to fish the ants.

In any case, Jane’s discovery became the talk of the scientific world. Harvard’s Stephen Jay Gould observed, “We must now re-think what the words ‘tool’ (工具) and ‘man’ mean or accept chimps as humans.”

1. What did Jane’s mother do when she found the worms on the bed?

A．She studied them carefully.	B．She shouted at her daughter.
C．She threw them into the garden.	D．She explained they liked the soil.

2. Which is the major reason that made Jane dream to work in the wild?

A．Doctor Dolittle’s invitation.	B．Her interest in chimps.
C．The reading in her childhood.	D．Her mother’s encouragement.

3. How did Jane feel during the first two months in Africa?

A．Lonely.	B．Frightened.
C．Hopeless.	D．Content.

4. What did Stephen Jay Gould’s words imply?

A．Chimps should be accepted as humans.

B．Jane’s discovery is of great importance.

C．Only human beings know how to make use of tools.

D．The scientists should confirm the meaning of the words.

4 . Did you see snow in your hometown last winter? Did you feel it was warmer than before?

“There have been 21 warm winters in China since 1986,” said scientists. They also said that in the past 100 years, as the global (全球的) temperatures went up by 0.74 °C , the temperature in North China has climbed 1.4°C in only 50 years.

China needs to take quick action to cut carbon dioxide (二氧化碳) emission (排放), because it’s the main reason for global warming. The good news is that China has seen the importance of going green. China set the goal of cutting energy use by 20 and pollution emission by 10 in the 11th Five-Year Plan.

Can you slow global warming? Sure! You and your family can take steps to cut the amount of carbon dioxide that is sent out into the air.

Here are some pieces of advice to help you save the earth.

Wear used clothes. Wearing your brother's, sister's or dad’s old T-shirt means you save the energy.

Change your light bulbs (灯泡). Use energy-saving light bulbs. And don’t forget to turn off the lights when you leave a room and turn off your television and computer when they are not in use!

Ride the bus. Taking a bus saves a lot of oil every year.

Say no to plastic bags. The next time your parents go to the market, ask them to use baskets.

Open a window. Don’t use the air conditioner (空调), and let some fresh air in. When you have to use the conditioner, set the temperature higher in the summer and lower in the winter to save energy.

Make small changes in your daily life. Don’t use paper cups, bags and boxes.

It's time for all of us to do something to save the earth.
