网上科普有关“九年级英语第三单元的短语和词组”话题很是火热，小编也是针对九年级英语第三单元的短语和词组寻找了一些与之相关的一些信息进行分析，如果能碰巧解决你现在面临的问题，希望能够帮助到您。

　1. Businessmen are afraid of newspapers and TV stations.

be afraid of sb./sth. 害怕某人或某事。

be afraid后面还可接不定式和v-ing形式，但二者之间有区别：be afraid to do表示由于主观原因不敢、害怕去做某事；be afraid of doing表示担心出现与主观良好愿望相违背的情况或不好的结果。如：

She was afraid to step further in the grass because she was afraid of being bitten by a snake.（她生怕被蛇咬着，而不敢往草丛中再走一步。）

She was afraid to wake her husband.（她不敢去叫醒她丈夫。）

She was afraid of waking her husband. （她生怕吵醒她丈夫。）

2. a year and a half

英语中表示“一个半”的方法有两种：① a/an +名词单数+and+ a half ② one+and+a half+名词复数。如“一个半小时”就有两种表达方式：an hour and a half或one and a half hours。

3. My friend said there was a car collecting rubbish outside.

collecting rubbish做car的后置定语。v-ing形式作后置定语时，通常表示被修饰词是动作的发出者且动作正在进行。如：Do you know the boy lying under the tree? lying这个动作就是前面的名词boy发出的，而且这个动作正在进行。

4. ...needs to do better in protecting the environment.

need 作实义动词时，后面可接名词、不定式和v-ing形式。如：

Everyone needs others\' help.

You don\'t need to know.

need后接v-ing形式时，主动形式表示被动含义。如：

My shoes need repairing.

= My shoes need to be repaired.

need还可作情态动词。如：You needn\'t go

一语天机（Unit 3）

1． waste

①作名词，可以和不定冠词连用，无复数形式。表示“浪费”或“废物”。

②作动词，表示“浪费……”、“未充分利用”。

③作形容词，表示“废弃的”、“无用的”。

2． story①通常理解为“故事”、“小说”，但在本课中指“报道”。

Unit 3 重难点解析

1.原文 I\'ve been with Greener China for a year. (L. 9 ) 句中be with是“参加”的意思吗？与join有什么区别？

精析be with是“参加”的意思，表示状态，可与时间段连用。而join表示“参加”时，是非延续性动词，不可与时间段连用。例如：

I\'ve been with the group for many years.我参加这个组织已经多年了。

I joined the army three years ago.我三年前就参军了。

2.原文“ It\'s a pleasant way to help keep our city clean,” said my friend. ( L.10 ) 这个句子是什么结构？to help keep...怎么理解？

精析这是由it作形式主语，不定式短语作真正主语的句子。这类句子由于主语较长，而用it作形式主语，把真正主语移至句末，使句子保持平衡。本句中的to help keep our city clean是真正的主语。再如：It\'s nice to meet you.见到你很高兴。

to help keep...意思是“有助于保持……”。keep our city clean是“keep + 宾语 + 宾语补足语”结构，作help的宾语。不定式作help的宾语常可省去to。

3.原文He\'s gone with his group to plant trees.（L. 11）plant有哪些用法？用作动词表示“种植”时，与grow相同吗？

　 精析plant可用作名词，表示“植物”，如：Plants need light and water.植物需要光和水。用作名词时，还有“工厂”的意思，常指大型工厂。如：A new power plant was built last month.上个月新建了一个发电厂。plant用作动词，意为“种植”，可表示种植各类植物。grow也可表示“种植”，多指种植农作物类，一般不用于植树。试比较：

They plant many trees in North China.他们在中国北方种了许多树。

They grow rice in South China.他们在中国南方种植水稻。

4.原文 I suppose we\'ll go there next week. (L. 11 ) suppose与think有区别吗？　 精析有。二者都有“认为、想”的意思，think含有推理、判断形成看法之意。suppose近似于think，但含不确切之意。在“suppose + (that) 从句”这一句式中，若主语是第一人称,其从句若为否定形式，应将否定词前移至主句，用法同think。如：I don\'t suppose he will come. 我猜他不会来。

5.原文...ask them to stop pouring dirty water into the river or the lake nearby? （L. 12） 请讲一下stop doing 与stop to do的区别。

　 精析stop后接v-ing是“停止做某事”，v-ing是stop的宾语，被停止的对象。stop 后接to do意思是“停下来去做另一件事情”，to do是目的状语。试比较：

It\'s time for class. Stop talking, please.该上课了，请不要说话了。

We have worked for a long time. Let\'s stop to have a rest.我们工作很长时间了，让我们停下来休息一会儿。

高中英语必修4 UNit2 an early farmer pioneer原文以及翻译如下：

Unit2---An early farmer pioneer

Some people thought Jia Sixie was a lucky man.He had worked for the emperor and when he got old,he was able to go to his hometown to relax. Jia Sixie, however, had other plans. He had always been interested in agriculture and intended to do something to make Chinese farming even better.

Jia Sixie lived in the sixth century AD. He was born in Yi du in Shandong Province and worked in Gaoyang, which is also in Shandong. As he rode through the country side on his journeys for his work he looked out at the fields. Some of them were greener and had more crops than others. Some cows and sheep looded healthier than others too. He was lost in thought. What could a farmer do to get good crops from his fields? Surely there must be rules that would help them. He thought he could use his knowledge to find out the best ways for farmers to grow crops and then write a book to help them. In doing so he collected information from farmers who did well, studied it and did experiments to find the best way.

For example, he studied ways of keeping seeds and advised farmers to choose seed-heads which had the best colour. Then he told them to hang them up to dry all winter. The next spring the seeds should be knocked out of their seed-heads and planted. He studied how to improve the soil. He advised farmers to clean weeds from the ground before planting crops. They could either let the animals eat the weeds or turn the soil over so that the weeds were covered and would rot. Then he gave advice on turning over the soil. The first time each year, farmers should dig deeply, but the second time should be less deep.Therefore the autumn ploughing of the soil should be deeper than the spring ploughing. He suggested changing crops in the field every year: rice one year and wheat the next so that they would always get good harvests. They should also grow different plants next to each other in the field. He also gave advice on how to fish, keep a garden and even make wine.

He wrote down his advice in a book called QiMin Yao Shu, which was considered an important summary of the knowledge off arming. For centuries after Jia Sixie died, it was studied by Chinese farmer sand students of agriculture.

早期的农民先锋

一些人认为贾思勰是一个幸运的人。他曾为皇帝效力，而且当他老的时候,他回到家乡去养老。然而,贾思勰已经有了其他的计划。他一直对农业感兴趣,还打算做些事使中国农业变得更好。

贾思勰生活在公元六世纪。他出生在山东省宜都市,在山东皋阳工作。当他在乡野之间骑马查看工作时他眺望那一片片的田野。它们中的一些田地比其他田地更加葱绿，结了更多的作物。一些牛和羊看上去也比别家的更健康。他陷入了沉思。一个农民要怎么做才能从他的田地中获得好的农作物呢?无疑一定有有助于他们的方法。他认为他可以用他的知识为农民找出这种方法种植农作物,然后写一本书来帮助他们。为了做这些他从有经验的农民那里收集信息, 并研究和实验, 以求找到最好的方法。

例如,他学习保存种子的方法并劝告农民要挑选有最好色泽的种子。然后,他告诉他们把种子挂起来晾晒一冬，使其干燥。来年的春天就可以从粮仓里取出种植。他研究过如何改良土壤。他劝告农民种植作物之前先锄去杂草。或者他们可以让牲畜把杂草吃掉或进行翻土,使野草被覆盖,最终腐烂。然后他又对如何翻土做出了建议。每年年初,农民应该挖的深一些,但是第二次应该比第一次稍浅一些。因此秋天犁地应该比春天犁地更深一些。他建议每年轮换种植作物: 种植大米一年，次年种植小麦, 这样他们就总有收成。他们也应该在田地里种植与相邻田地不同的作物。他也对如何养鱼,维护花园,甚至对如何酿造葡萄酒做出了建议。

他把他的建议写在一本叫做《齐民要术》的书中,这被认为是一本非常重要的农作物种植总结。在贾思勰死后的几个世纪里,中国众多的农民和农业科学的学生都在学习这本书。
