--- Shall we take some coke to your home? B. 以some-, any-, no-, every- 开头的词 1) something someone somebody 2) anything anyone anybody 3) nothing no one nobody 4) everything everyone everybody

以上这些词都是不定代词,如果有形容词或其他短语来修饰这些词时,放在这些词的后面,如:

nothing much 没什么 something interesting 一些有趣的事

C. both & all 1) both指“两者都”,后面动词用复数形式,其反义词是neither (两者都不)

2) all指“三者或三者以上都“,all后面加可数名词复数时,动词用复数形式,all后面加不

三、例题精析

【例题1】

1. Who’s singing over there ? — ________ is Sandy’s sister. A. That B. It C. She D. This

【答案】:C 【解析】:此题考察人称代词的用法,根据语境,回答是Sandy’s sister,而且句子缺主语,

所以要填写人称代词的主格形式 she, 故答案是C。

【例题2】

Our school is big. is small. A. His B. Him C. It D. He 【答案】:A 【解析】:此题考查物主代词的用法,根据语境,句子的意思是表达他的学校是小的,所以

用名词性物主代词his代替了his school, 故答案为A。

【例题3】Don’t give children money. It is not good for them. A. too many B .too much C. many too D. much too 【答案】:B

9

个性化教案

【解析】:本题考查固定短语too much的用法,too many和too much都是太多的意思,但是

前者加可数名词,后者加不可数名词,money为不可数名词,many too本身是错误表达,much too为太...的意思,后面加的是形容词,故选A。

【例题4】

Ben works for his test to the USA,so he moves his body all day. A. hard; hard B. hardly; hardly C. hardly; hard D. hard; hardly

【答案】:D

【解析】句意为“Ben在努力准备去美国的考试,所以他整天几乎没有运动”,work hard 是努力学习的意思,而hardly是几乎不的意思,,故答案问D。

In 1972, the important ancient copies of the Art of War were found in Linyi. This helps to understand Master Sun's military art greatly.

The best time to collect green leaves is early in the leafing season but not so early. The months

14

个性化教案

of June and July provide the best leaf samples but you can find great leaf samples throughout the summer. To make a fall colour collection you have to collect the leaf in autumn. I have seen many beautiful fall color collections.

When you select leaves for your collections, try to select leaves of about the same size and shape on the tree. Make sure you should collect the complete leaf.

Remember , simple leaves have only one blade(叶片) or leaflet. Compound leaves have several or many leaflets. You must know these two kinds of leaves. Good leaf collections contain the entire leaf. That is a small part of the twig(嫩枝) with a lateral or terminal bud(顶芽)。

You should dry the collected leaves carefully before placing them in a leaf press. When you collect leaves in the field, you can place them between the pages of a magazine to protect them. And then, press them as soon as possible before you remove them from this magazine. Finally , place them in a leaf press. You should write down each leaf's name and these names should follow the leave until the exhibition coming.(228 words)

1. Which months are the best times to collect green leaves?

A. February and March B. April and May
