14、 hardly ever 几乎不，

二、习惯用法、搭配

want to do sth. 想做某事，

be going to + 动词原形：将要做某事，

practice doing sth. 练习做某事，

keep on doing sth.继续做某事，

learn to do sth. 学会做某事，

finish doing sth做完某事，

promise to do sth.答应做某事，

help sb. to do sth.帮助某人做某事，

remember to do sth. 记住要做某事，

agree to do sth.同意做某事，

love to do sth.喜欢做某事，

be going to 的用法

1）   be going to + 动词原形——表示将来的打算、计划或安排。常与表示将来的tomorrow, next year等时间状语或when 引导的时间状语从句连用。各种句式变换都借助be 动词完成，be随主语有am, is, are 的变换，going to 后接动词原形。

肯定句： 主语 + be going to + 动词原形 + 其他。he is going to take the bus there.

否定句： 主语 + be not going to + 动词原形 + 其他 i’m not going to see my friends this weekend.

一般疑问句： be + 主语 + going to + 动词原形 + 其他

肯定回答： yes, 主语 + be.                   否定回答： no, 主语 + be not.

are you going to see your friends this weekend?   yes ,i am.   /    no, i’m not.

特殊疑问句： 疑问词 + be + 主语 + going to + 动词原形 + 其他？

what is he going to do this weekend?   when are you going to see your friends?

2) 如果表示计划去某地，可直接用 be going to + 地点

we are going to beijing for a holiday.

3) 表示位置移动的动词，如go , come, leave 等常用进行时表示将来。

the bus is coming.              my aunt is leaving for beijing next week.

4) be going to 与 will 的区别：

① 对未来事情的预测用“ will + 动词原形”表达，will 没有人称和数的变化，变否定句要在will 后面加not,

也可用will 后面加 not,或者缩略式won’t, 变一般疑问句将will 提至 句首。

will planes be large in the future?         yes, they will. /  no, they won’t.

②will 常表示说话人相信或希望要发生的事情，而be going to 指某事肯定发生，常表示事情很快就要发生。

i believe lucy will be a great doctor.

③ 陈述将来的某个事实用will.    i will ten years old next year.

④表示现在巨大将来要做的事情用 will.   i’m tired i will go to bed.

⑤ 表示意愿用will.     i’ll tell you the truth.

⑥ 表示计划、打算要做的事情用 be going to, 而不用 will.

i’m going to buy a computer this month.

---let’s discuss the plan, shall we?   ----not now. i ______ to an interview.  a. go  b. went   c. am going  d. was going

------jack is busy packing luggage.   ---yes. he ____for america on vacation.  a. leaves b. left  c. is leaving  d. has been away

三、重要句子（语法）

what do you want to be when you grow up?                i want to be an engineer.

how are you going to do that?                       i’m going to study math really hard.

where are you going to work?                        i’m going to move to shanghai.

when are you going to start?              i’m going to start when i finish high school and college.

四、词语辨析

1 promise vt. 保证，许诺。有三种结构：

1)promise to do sth. ——my mother promised to buy a piano for me.

2)promise sb. sth.  ——my aunt promised me a bike.

3)promise + that 从句——tom promises that he can return on time.

promise n. 允诺， 诺言   lily is a dishonest girl. she never keeps a promise.

与 while 的区别：

when 表示“当…时候”，既指时间点，又指一段时间，when 引导的时间状语从句中的动词可以是终止性的也可以是延续性的。when the teacher came in, the students were talking.

when she arrives, i’ll call you.

while 表示“当…时候”，仅指一段时间，从句中的动作必须是延续性的，一般强调主从句的动作同时发生， while  还可以作并列连词，意为“ 而、却”，表示对比关系。

lisa was singing while her mother was playing piano.

tom is strong while his younger brother is week.

3. practice vt.  练习， 后接名词，代词或v-ing 作宾语。

your elder sister is practicing the guitar in the room.

常跟v-ing 作宾语的动词有：

考虑建议盼原谅：consider, suggest/advise, look forward to, excuse, pardon.

承认推迟没得想： admit, delay/put off, fancy.

避免错过继续练：avoid, miss, keep/keep on, practice.

否认完成能欣赏： deny, finish, enjoy, appreciate.

不禁介意与逃亡： can’t help , mind, escape.

不准冒险凭想象： forbid, risk, imagine.

4. everyday 与 every day 区别

everyday  adj. 每天的   在句中作定语，位于名词前。 this is our everyday homework.

every day  副词短语， 在句中作状语，位于句首或句末。 he reads books every day.

七年级上英语外研版 computers教学设计

一、教材分析

本课以电脑为话题，围绕da ming与 lingling 的对话展开活动，内容涉及如何使用电脑完成作业、世界不同的地方的人们对电脑的使用程度等，既贴近生活，又开阔学生视野。在本模块的教学中，应充分利用学生在电脑方面的知识来促进英语学习，鼓励他们有效地利用电脑来学习。

二、学情分析

初三学生具备一定的捕捉信息的能力，有了表达的欲望。通过前面几个模块的学习，以具备一定的知识基础，这为本节课学习过程的顺利开展创造了较好的条件。

三、学习目标

2、读懂含有一般现在时的句子，掌握一般现在时的特殊疑问句和答句。

五、教学策略

本模块三个单元，我根据每个单元的不同特点进行复习，遵循听说领先、读写跟上的教学原则，训练学生听力；突出实践能力并训练书面表达；适当增加阅读材料。目的是培养学生自主学习，合作交流，创新探究的学习品质。

六、教具准备   多媒体       录音机        自制图片

选作作业：（走近中考）

一、阅读理解

we are already familiar with computers—computers work for us at home, in offices and in factories. but it is also true that many children today are using computers at schools before they can write. what does this mean for the future? are these children lucky or not?

many people who do not know about computers think of them as machines that children play with. they worry that children do not learn from experience but just from pressing a button and that this is not good for them. they think that children are growing not knowing about the real world.

but people who understand more about computers say that computers can be very good for children. a computer can help them to learn about the real world more quickly, to learn what they want to learn and think for themselves. and for the future, don’t we need people who can think clearly, who know how to get information quickly and use it well? what do you think?

1. “to be familiar with” means to ______.

a. know nothing       b. know about       c. dislike       d. like

2. does everyone think computers are good for children?（   ）

a. yes, they do.   b. no, not everyone thinks they don’t know.  d. they are not sure.

3. what can computers help children to do?（      ）

a. to think clearly, to do homework and to write.

b. to play games, to do math and to copy.

c. to think clearly, to get information and to use it well.

d. to count, to clean the house and to get information.

4. does the writer think computer is a good thing?（    ）

a. it isn’t mentioned. b. no, he doesn’t think so.  c. he doesn’t know.  d. yes, he does.

设计目的：进一步加强对基础知识的巩固，并利用话题作文，来引导学生正确的使用电脑，并从中受益。让学生远离网络的不良伤害，建立正确的上网意识。利用与电脑有关的阅读理解来进一步开拓学生的视野，接触与之有关的知识。

八、课后反思

（一）课前检测，激活课堂。这是复习课的前提。

（二）自主、合作、探究是学生必备的学习策略，为其终身学习奠定基础。

（三）在教学中，我成功“345”课堂教学模式，使之与我校倡导的自主、合作、探究有机结合。实现了小组学习的成功尝试。

（四）过渡语的应用，学习高潮的设置，拓展阅读，增强了课堂的趣味性和凝聚力。

（五）课堂作业的布置，与中考连接，训练了学生的应考能力。

one morning, a blind boy sat beside a building with a hat by his feet. he held a sign which said, “i am blind. please help me.”

there were only a few coins in the hat. a man was walking by. he took out a few coins from his pocket and dropped them into the hat. he then took the sign, turned it around, and wrote some words on it. he put the sign back so that everyone who walked by could the new words.

soon the hat began to fill up. a lot more people were giving money to the blind boy. that afternoon the man who had changed the sign came to see how things were. the boy recognized his footsteps and asked, “are you the one who changed my sign in the morning? what did you write?”

the man said, “i only wrote the said what you said, but in a different way.”

what he had written was, “today is a beautiful day, but i can" t see it.”

do you think the first sign and the second sign were saying the same thing?

of course both signs told people the boy was the first sign simply told people to help by putting some money in the second sign told people that they were able to enjoy the beautiful day, but the boy could not enjoy it because he was blind. the first sign simply said the boy was blind, while the second sig told people they were so lucky that they were not blind.
