语言点解析

动词语态的复习
语态是表示主语与谓语的关系的。 如果主语是动作的执行者,动词要用主动语态 之,如果主语是动作的承受者,动作就要使用 被动语态。 (1) The naughty boy broke a glass yesterday.

(主语“淘气的男孩”发出“broken”的动作,是执行者, 因此用主动语态)

(2)A glass was broken by the naughty boy yesterday.

听力原文

Section A 1b

Boy: Hey, Ginny. What’s that big, furry animal in the pond? Girl: It’s a polar bear, Victor. They’re kind of aggressive. Boy: Are they? Looks like they really love water. Girl: Uh-huh. Boy: And what do you call those big, gray things in the water? Girl: They’re called manatees. Boy: What? Girl: Manatees. They are very gentle and shy. Boy: Oh. And how about the yellow and black spotted animals in that cage? Girl: They’re cheetahs. The Cheetahs is the fastest animals on earth.

Section A 2a&2b

Boy: Can you tell us about the manatees, please? Man: Sure. We’re trying to save them. Boy: Why? Are they endangered? Man: Yes. There used to be a lot of manatees, but now there aren’t very many of them. Boy: Do you know how many there are? Man: At this point, there are only about 2,500 in the U.S. In 1972, it was discovered that they were endangered Since then, the government has passed laws to protect them. Boy: Where do they live? Man: Their favorite habitat is the water under the trees in mangrove swamps.

Boy: And why are they endangered? Man: Some of the swamps have become polluted. Also, there sometimes isn’t enough food for all of them. As you can see, they’re large. The average manatee is about three meters long and weighs about 1,000 pounds. They need about 100 pounds of aquatic feed a day. Boy: Aquatic feed? Man: Oh, that

’s underwater plants and vegetation. That’s what they eat.

Section B 2a&2b Boy: Hey, Julia. Don’t forget to turn off the lights. It saves electricity. Girl: Oh, I know. I usually do that. I was just in a hurry. How come you’re so interested in the environment, Jack? Boy: I always have been. Lots of people think there’s nothing they can do, but I just read this book about it, and there are lots of things the average person can do. Girl: Like what ? Boy: Well, you should turn off the shower when you’re washing your hair. Girl: Oh, I’d never do that! Boy: Well, every minute helps.

Girl: What else does it say? Boy: It says you should take your own bags when you go food shopping. Girl: Oh, that’s not difficult. I can do that. What else? Boy: Hmmm. Here’s a good one. It says people should stop riding in cars and start riding bikes. Girl: Oh, I’ll never do that! Can you see me riding 45 minutes to and from school every day? Boy: Well, I think the environment is really important. Besides, I like riding my bike. Girl: Yes, and you also live close to school!
