Section II Learning about the language
一、课前预习
I. 重点短语
1. 保护……免受______________________________
2. 寻找,搜寻________________________________
3. 吹响号角__________________________________
4. 与……有关________________________________
5. 濒危物种__________________________________
II. 完成句子:用上面的短语完成下列句子。
1. He raised his arm to                 his face                 the blow.
他抬起胳膊挡住脸,以防挨打。
2. He turned the room upside-down to                 the lost key.
他把屋子翻得乱七八糟,寻找遗失的钥匙。
3. The giant panda has become                .
大熊猫已成了一种濒临灭绝的动物。
4. You should not                 because you want the traffic to move faster.
不能为开快车而鸣笛。
5. She claims that she                  the Queen
她声称和女王有亲属关系.
二、语法突破:现在进行时态的被动语态
1. 概念:表示一个被动的动作正在发生或进行,强调主语是动作的承受者。
2.用法:被动语态的主语是动作的承受者,它主要用于当我们强调动作的承受者或难以或不必说出动作的执行者时。
基本句型 am/is/are+ being+及物动词的过去分词
用法 1) 表示说话瞬间正在进行的被动动作。
 His father is being interviewed. 
他父亲正在接受采访。
2) 表示现阶段正在进行的动作,但该词在说话的瞬间未必正在进行。
 The house is being built.   
这座房屋正在建设中。
3) 表示一种习惯的被动行为,常与always, constantly等词连用,一般带有赞扬,羡慕,埋怨,讨厌等感情色彩。
She is always being praised by the teacher.    
她总是得到老师的表扬。
4) 现在进行时态的被动语态可和情态动词连用表示说话者对正在发生的被动行为的推测。
The patient must be being examined.         
病人一定是正在接受检查。
3.被动语态运用时要注意:
(1) 形式要正确。被动结构的形式为“助动词be+过去分词”。主动词总是用过去分词,其结构形式的变化在于be上。我们可以从be主动语态的不同形式推出被动语态相对应的八种时态形式和其他形式。每个形式与其相对应的主动形式在用法和意义上都一致。例如:
The film is being shown now. 电影正在放映。
is being是be 的现在进行式;shown不能误用过去式showed或现在分词showing
(2) 表示“状态、心理活动、拥有、存在”等的动词,一般不用现在进行时的被动语态,而常用一般现在时的被动语态。
Mary, you are wanted on the phone. 玛丽,有你的电话。
(3) be+ under/in等介词+n.结构,可表示现在进行时的被动语态的含 义。
The bridge is under construction= is being constructed. 这座桥正在建设中。
The telephone is in use= is being used. 这部电话正在使用。

 I suddenly heard an elephant crying as though frightened. Looking down, I immediately recognized that something was wrong and ran down to the edge of the near bank. There I sa w Ma Schwa   with her three-month-old calf struggling in the fast-rising water and it was a life-and-death struggle. Her calf was floating and screaming with fear. Ma Schwa was as near to the far bank as she could get, holding her whole body against the rushing water and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean over the mother’s body and was gone. Ma Schwa turned quickly to reach it and pressed the calf with her head and trunk(象鼻)against the rocky bank Then with a huge effort she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment she fell back into the river. If she were carried down it would be certain death. I knew as well as she did, that there was one spot(地点)where she could get up the bank  but it was on the other side from where she had put her calf.
While I was wondering what I could do next, I heard the sound of a mother’s love. Ma Schwa had crossed the river and got up the bank and was making her way back as fast as she could, roaring(吼叫)all the time, but to her calf it was music.

II.根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
    Do you know something about tree rings? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?
          1           And little sunshine or rainfall will limit the growth of a tree. We can see the change of climate by studying the tree rings of a tree from the outside to the inside. If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year.           2         
Tree rings are important not only for studying the history of weather but also for studying the history of man. Many centuries ago there lived a lot of people at a place in New Mexico.    3   
What happened?
