OONNGrammar: 用情态动词表示 “许可”。1. May 的用法
(1)表示允许或征询对方的许可,有 “可以”的意思。may not 表示说话人不许可。如:
You may go now. 你现在可以走了。
May I use your telephone?
我可以用你的电话吗?
You may not go.=I do not permit you to go
我不允许你走。 (2)在回答 may 引导的疑问句时,肯定回答用 Yes, you may. 否定回答用 No, you mustn’t. No, you can’t 或 No, you had better not.
在表示 “不可以”、“禁止”、“阻止” 的意思时,
常用 must not (mustn’t) 代替 may not。如:
—May I smoke here? 我可以在这儿抽烟吗?
—Yes, please. (No, you mustn’t.) 请抽吧。(请不要抽)
(3) may 表示可能,通常用于陈述句。(may 表示的可能性比 might 大)。如:
You may be right. 你可能是正确的。
It might rain today. 今天可能下雨。
(4) 在口语中,can 可以代替 may 表示许可, 而 may 比较正式。如:
Class is over. You can go home now.
下课了,你们可以回家了。
Can I use your camera?
我可以用你的相机吗?(5)might 、could 用于现在时,语气比较委婉、礼貌。如:
Might / Could I invite you to dinner?
我可以邀请你吃饭吗?
can 可以在口语中代替 may,表示允许,有
“可以” 的意思。
Can I use your bike?
我可以用你的自行车吗?

home.
图书管理员说我们可以把书带回家。
Grammar: 宾语从句(一)1. 定义:宾语从句就是一个句子在另一个句中作主语,即宾语从句是用句子作宾语。
2. 由 that 引导的宾语从句
that 在句中不充当任何成分,只起连接主句和从句
的作用,that 不用翻译出来,在口语中常常省略,
这种宾语是陈述句。如:
The trouble is that we are short of money.
困难在于我们缺钱。
She said that she would come.
他说她要来的。3. 由if / whether 引导的宾语从句whether 或 if 在句中不充当任何句子成分,只起连
接作用,但不能省略,应在句中翻译成 “是否”。
如:
Do you know if Mr. Smith is at home?
你知道史密斯先生是否在家?
She asked if that was enough.
她问那是否够了。
Let me know if you are coming.
如果你来,就通知我。把下列句子合并为宾语从句。

whether,而主句的谓语动词是一般现在时,
所以宾语从句也用一般现在时。

not?2. 选择填空:

般疑问句。一般疑问句的宾语从句用正常语序。题
中已经给出,不必考虑。要考虑的是if引导的宾语从
句,如果主句是一般将来时,那么从句要用一般现
在时。本题的主句正是一般将来时,故选 C。

打开电视以……开始想要be different fromworry aboutbe afraid ofwhat aboutgo together 略读是一种快速阅读方法,目的不是为了帮助搜寻细节,而是为了了解文章的知识结构,找出文章的中心思想等宏观信息。因此,略读时只需注意文章的关键部分,如文章的第一段和最后一段,每段的第一句和最后一句。文章的中心思想与它的题目有很大关系,根据题目可以大致猜出文章的内容,每个段落往往有主题句,告诉该段的主要内容。通过题目和主题句并结合作者的目的或意图,可以推测出文章的中心思想,所以在略读时只需重视文章的题目和主题句。主题句是每段的概括性句子,往往是段落的第一句话,有时也存在于段落中间或段落末尾。所以通过略读寻找文章的主题句,不能只看段落的第一句话。 阅读方法介绍—略读阅读方法介绍—浏览 这一方法忌讳的是逢词逢句必读、反对一字一句阅读,这样做会严重影响阅读速度。正确的阅读方法只看不念,眼睛快速搜索信息并及时反映给大脑,眼睛浏览速度不受大脑反映速度的限制,大脑的反映速度要跟上眼睛的浏览速度。阅读时眼睛集中在一个词组中的一个单词,一句中的几个关键词组。浏览后能够对文章有一初步印象,了解文章的整体结构,知道文章的主要内容,熟悉材料在文章中的大概位置。浏览时遇到不懂的问题可以暂时跳过,不要花太多的时间,因为可能与问题的回答没有任何关系,可能对文章整体意思的理解没有任何作用。浏览时脑子要想着问题,遇到与问题相关的材料,一定要做好标记。 Life on MarsAnimals Angry when angryEating anything(1)________________(2)________________________Usually friendlyKeep them away from with laser lightMoney ¥ 1is worth M$10Money is stored at the (3)_____________________Planet Mars BankMost t things are cheaper on Mars than on Earth.TransportComfortable and never late.___________________________________(4) Cars float in the air._____________________________________________(5) No air pollution caused by traffic.
