必修四
Discovering useful words and expressions
1 Find the word or phrase from the text for each of these meanings.
1.只能后接动名词作宾语的动词, 常见的有 avoid, consider, enjoy, keep, finish, suggest, dislike, delay, escape, cannot help, imagine, mind, miss, practise, cannot stand等。 如： I can’t avoid going． Have you considered looking for one special friend?
1. 表示经常的、习惯性的动作或状态, 谓语动词通常用单数。如： Walking is a good form of exercise for both young and old. 无论对年轻人和老年人来讲, 走路是一种 很好的锻炼。 Watching news on TV has become a routine for me. 在电视上看新闻已经成了 我的一种日常习惯。
常用-ing形式作主语的句型
• It +be +a waste of time doing 做……是浪费时间的 • It is/was no good/use doing 做……是没用处的 • It is/was hardly/scarcely worth doing 做……不值得 • It is/was worth/worthwhile doing 做……是值得的 • There is no doing... 无法……; 不允许……
3. 在there is no + Ving 的结构中如： There is no hiding of evil but not to do it． 若要人不知, 除非己莫为。
There is no joking about such matter.
这种事开不得玩笑。
1、 动名词作主语表单数概念,谓语动词用 单数形式。 Walking after supper is good for your health. 2、 动名词的复合结构作主语 动名词的复合结构是指物主代词、名词所 有格是动名词逻辑上的主语、动名词是其 逻辑上的谓语。 Your coming made us happy. Your father’s cooking is very good.
动名词与不定式做主语时的比较：
动名词表示的动作通常是一个泛指的动作, 不定式则通常表示具体的动作。 如： 还是个孩子的时侯, 她就觉得探视病人是 一种责任, 也是一种愉悦。 As a child, she felt that visiting sick people was a duty and a pleasure．
Doing nothing is doing ill． 一直不做就是作恶。 He said, “To go on like this is useless .” 他说: “继续这样下去是无用的。” It’s an honor for me to be invited to the party. 我很荣幸被邀请参加这个晚会。

1. information: statistics; world: globe 2. Strong: super; races: nationalities 3. Not having enough food: hunger; sickness: disease 4. A small Southeast Asian country: Vietnam; jobs: occupations 5. Open conditions: freedom sold and sent abroad: exported
2. -ing形式作主语时常后置, 此时须用it 作形式主语, 用形容词或名词作表语。 常见的名词或名词短语有: no use, no good, fun, hard work, a hard / difficult job, a waste of time 等; 形容词有: dangerous, worthwhile, useless等。如: It’s no use making an excuse for this. 为这件事找借口是没有用的。 It’s dangerous swimming in the sea on windy days. 有风的天气在海里游泳是危险的。
考 例
D that with them. 1. I can’t imagine _____ A. do B. to do C. being done D. doing 2. She looks forward every spring to D the flower-lined garden. _____ A. visit B. paying a visit C. walk in D. walking in
The –ing form as the Subject and Object
Have you ever seen these signs?
parking, spitting, littering, smoking
动词-ing形式
1. 构成: 在动词末尾加-ing 。 否定形式: not+ -ing 构成 2. 动词-ing形式不能单独作谓语, 没有人称和 数的变化, 但可以有自己的宾语和状语, 还有 时态和语态的变化。 3. 动词-ing形式由动词加-ing变化而成, 它同时具有名词和动词的特征, 在句中可以 作主语、宾语等。
在动词forget, remember, regret之后, 用 动名词与不定式意义不同。动名词表示动作
先于谓语发生,不定式表示后于谓语动作。如：
这类动词还有: excuse, fancy, give up,
put off, risk, insist on, look forward, feel like等。
当 need, want, require, worth后面接动词ing也可以表示被动。 Your hair wants cutting. The floor requires washing. That novel is not worth reading.
3 Complete the passage with the words below in their proper forms.
disturbing expand output struggle battles grain crops decade equip
In the past _______, decade some of the farmers in the west of China have met with some struggle against the success in the ________ expanding desert. _________ Equipped with new __________ scientific farming methods,
2. 既可接动名词又可接不定式作宾语的动词, 常见的有: begin, start, continue, like, love, prefer, by, mean, forget，remember, hate等。 在 like, love, hate, prefer等动词之后， 用-ing或不定式意义上没有什么不同, 只是侧重 点有些不同, 动名词表示泛指的动作, 不定式表示具体的一次性动作。 在 begin/start, continue之后, 用动名词和 不定式, 意义无甚区别, 尤其是当主语是人的 时候。
they have been able to use less farmland output of _____ grain than in the past. Their ______ crops however, is still the and other ______, same, which makes it possible for them to use the remaining farmland for planting trees. These and other farmers battles in the are starting to win small ______ disturbing growth great war against the __________ of the desert.

Unit2 learning about Language 名师教学设计人教版高中英语M4U2 Learning about Language教学设计一、教材分析本单元的中心话题是“农业”，内容涉及我国著名的杂交水稻专家袁隆平的贡献、化肥对土地耕种的影响以及开展有机生态耕种等。
学生对于农业的话题较为陌生，因此本单元词汇学习重设语境，从三国演义中学生耳熟能详的故事着手，结合社交媒体和多媒体应用帮助学生熟悉并掌握以下词汇：occupy; disturb; struggle; regret; satisfy; comment; focus; lead to; thanks to; freedom 。
二、学生分析授课对象为高一学生，学生喜欢轻松的话题，具备一定的词汇基础和中国古典名著的知识基础。
因此，本次设计从热门微博中三国演义片段着手，能较好地吸引学生，激发学生的语言学习兴趣从而进一步掌握该单元词汇。
但是学生对于词汇的用法缺乏系统的认知和理解，运用能力弱。
因此本次课题结合教授与运用，着重提升词汇运用能力。
三、教学目标1.语言能力学生能熟悉并运用以下词及词组的用法:occupy; disturb; struggle; regret; satisfy; comment; focus; lead to; thanks to; freedom 。
2. 学习能力学生能通过个人、同伴互助和小组讨论等方式，在观察、思考、游戏等过程中，正确归纳、比较和运用重点词和词组的涵义和用法。
3.文化品质学生能加深对中国经典著作的理解，致力于传统文化的学习与传播，让传统文化焕发生机，赋予时代意义持续传承下去。
四、教学重点通过语境呈现、填空、实操等方法，帮助学生学习掌握以下重点词及词组的意义和用法:occupy; disturb; struggle; regret; satisfy; comment; focus; lead to; thanks to; freedom 。
