Unit 5 Amazing Animals
要点攻略
cold 单词小议
cold形容词（colder， coldest），表示“冷；寒冷的；冷淡“；名词，表示“寒冷；感冒“。本单元主要表示“感冒“。常用的短语：keep the cold out 御寒；catch/ have/ get a cold 受凉；感冒；easily take colds 容易伤风；take a bad / heavy cold 患了重伤风；
例如：
Winter is the coldest season of the year. 冬天是一年中最冷的季节。
They made a cold response to the matter. 他们对这个问题反应是冷淡的。
There is a lot of air in loose snow， and this helps to keep the cold out. 松散的雪里有大量的空气，这有助于御寒。
He have caught a cold for a week. 他患感冒一周了。
注意习惯用法：
have/ get a cold 一定要有a。
You‘ll catch ( a ) cold. 此处a可有可无。
Half the boys in the class were absent with bad colds. 班上半数学生因患重感冒缺课。
辨析：
cold“寒冷的，冷的“，反义词是hot （热的）；cool“凉爽“既不热也不冷，反义词是warm（温暖）。
了解一下“跳“的不同jump / hop / leap / spring
这些词都表示“跳“的意思。但略有不同。
jump是最普通用语。这任何位置、方向的跳跃。例如：
The boy jumped across the puddle. 小男孩跳过水坑。
She jumped out of bed as soon as she was called. 她一听见有人叫她，立即从床上跳下来。
spring 指动作优美轻盈的弹跳。例如：
The branch sprang back and hit him on the face. 树枝弹回来打了他的脸。
The dog tried to spring over the gate. 那条狗想从门上跳过去。
leap 指大跨度的快速跳跃，比jump的动作优美、轻捷。例如：
The young deer were leaping about in the meadow. 小鹿在草地上跳来跳去。
A fish leaped out of the water. 鱼儿跃出水面。
hop 指人单足跳，也可指鸟、蛙等跳动。例如：
As her left foot was hurt， she had to hop along. 她因左脚有伤，不得不单腿跳着走。
The birds came hopping round my window. 鸟儿飞到我窗前，跳来跳去。
hear用法
辨析hear / listen
辨析hear / hear of / hear from
hear 动词“听，听见，听说，听取“，过去式及过去分词为heard。常用结构有：
hear sb do sth 听见某人做某事（一个完成的动作或某个动作的全过程）
be heard to do sth 被听见做......
hear sb doing sth 听见某人正在做某事（一个正在进行的动作）
hear + that 从句，“听说......“
hear about / of ... 听人说起
hear from sb 收到某人的来信
例如：
I hear him go out. 我听见他出去了。
The children were often heard to sing this song. 常听孩子们唱这首歌。
I heard them talking in the next room. 我听见他们正在隔壁房间交谈。
I hear that he has gone to Paris. 我听说他已去了巴黎。
They had often heard of elephant， but they had never seen her. 他们常听见人说起大象，但从未见过一只。
Have you heard from John recently? 近来你收到约翰的信了吗？
辨析hear / listen
hear和listen都有“听“的意思。但用法不同。Hear是“听见“，不一定都是有意的，有时是偶然听见；而listen则是“仔细倾听“，是不及物动词，一般与介词to连用。Hear则指听得结果，通常不用进行时态；listen则指听的过程，可以有进行时态。例如：
I listened but could hear nothing. 我注意听，但什么也没听见。
I can hear somebody coming. 我听到有人正在走来。
辨析hear / hear of / hear from
hear用作及物动词时，可做“听、听见“讲，指亲耳听到，后面接宾语（或宾语+不定式或现在分词）；也可做“听说、得知“讲，指听到别人说某一件事，后面接宾语从句。例如：
　I heard them singing in the classroom. 我听见他们在教室里唱歌。
I hear that they are singing in the classroom. 我听说他们正在教室里唱歌。
hear of 也作“听说“讲，指听到别人说起某人或某事，后面通常接名词和代词。例如：
I have never heard of such a man. 我从来没有听说过这样一个人。
hear from的意思是“收到......的来信“，后面接名词或代词。例如：
　I hear from him every month. 我每月都收到他的信。
辨析be able to / can
be able to 和can的意思相近，但be able to 可有更多的时态形式。另外它还可以用于不定式或动名词短语中。例如：
I‘d like to be able to stay here. 我想要呆在这儿。
He said he regretted not being able to swim. 他说他对不会游泳感到遗憾。
I shall be able to come next Tuesday. 下周二我能来。
Can的过去式could，在表示“一般的能力“，即你想干什么就可以干什么时，可以与was / were able to 互换，但是在表达过去某种具体的能力，即在某种场合作某事的能力时要用was / were able to， managed to。
例如：
At last she was able to look up with tearful eyes and smile and say ....
最后她抬起头，眼含泪水微笑着说...... （不可以说成...she could look up...）这种用法在否定句中它们之间并无区别。 Be able to 不可表示“允许“， 如：不可说You are able to go now. 应该改为You can go now. 你现在可以走了。
例如：My brother is able to / can drive a car. 我弟弟会开汽车。
They stood there， unable to make a decision. 他们站在那犹豫不决。
We were able to do the work. 我们能做这项工作。
She is able to swim. 她会游泳。


你问我答

答：好的。
record动词，表示“录音/像；记录；记载“。例如：
She recorded everything that was said at the meeting. 她记下会议的全部发言。
