The earth is getting warmer. People burn coal, oil and gas and this produces carbon dioxide, methane（沼气）and nitrous oxide. These gases, called “greenhouse gases”, prevent the heat of the sun from leaving the earth’s upper atmosphere and this makes the earth warmer
A few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. According to what they found, the scientists say that during the next 50 years about 25% of land animals and plants will become extinct. More than a million plant and animal species will be extinct by 2050.
More than 10% of all plants and animals will become extinct. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we could save many more plant and animals from extinction.
The scientists studied some regions of the world with a very rich biology. These were Europe, Australia, Central and South America, and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill, to get cooler. In flat areas, such as deserts, plants and animals would have to move a very long distance to get cooler, so they are in grater danger of extinction.
The scientists found that half of the 24 species of butterflies they studied in Australia would soon become extinct. 60% of the species in the Kruger National Park in South Africa would also die out, and more than 100% of the 300 South Africa plant species they studied would also become extinct. One of the plants in danger of extinction is the national flower of South Africa, the King Protea. They studied 163 tree species in the Cerrado region of Brazil and found that 70 would become extinct. Many of the plants and trees that live in the region live nowhere else in the world. In Mexico, they studied 1,870 species and found that more than 30% of these were in danger of extinction.
Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock 36 Here is how to make one.
● 37 In order to make a change, you need to decide why it's important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reason, tell your family or roommates about the change you want to make.
Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. 3 8 That's a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.
Keep your sleep/wake schedule on weekends. If you're tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found. 3 9

If anyone had told me three years ago that I would be spending most of my weekends camping. I would have laughed heartily. Campers, in my eyes, were people who enjoyed insects bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me. 36
The friends who introduced me to camping thought that it meant to be a pioneer.
37We sleep in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor`s bill for my son`s food poisoning.
I was, nevertheless, talked into going on another fun-filled holiday in the wilderness.
38 Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.
39 We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.
40 It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.
| A． |
This time there was no tent. |
| B． |
Things are going to be improved. |

| E． |
I must say that I have certainly come to enjoy camping. |

After the trip, my family became quite interested in camping. |
| G． |
There was no shade as the trees were no more than 3 feet tall. |
Everyone knows that fish is good for health. 16But it seems that many people don't cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn't difficult. 17 This text is about how to buy and cook fish in an easy way.
18 Fresh fish should smell sweet: you should feel that you're standing at the ocean's edge. Any fishy or strong smell means the fish isn't fresh. 19 When you have bought a fish and arrive home, you'd better store the fish in the refrigerator if you don't cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn't as tasty as the fresh one.
There are many common methods used to cook fish. 20First, lean it and season it with your choice of spices(调料). Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. (A larger one will take more time.) Then, it's ready to serve.
| A． |
Do not buy it. |
| B． |
The easiest is to steam it. |
| C． |
This is how you can do it. |
| D． |
It just requires a little knowledge. |
| E． |
The fish will go bad within hours. |
| F． |
When buying fish, you should first smell it. |
| G． |
The fats in fish are thought to help prevent heart disease. |
How to Do Man-on-the-Street Interviews
The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the sport. _____31_____But with these tips, your first man-on-the-street interview experience can be easy.
When your boss or professor sends you out to do man-on-the-street interviews for a story, think about the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, "Why do you think environmental protection is important in America?" _____32_____
Hit the streets with confidence. _____33_____Say, "Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic." This is a quick way to get people to warm up to you.
