8下英语7单元2d知识点讲解

❶ 新目标八年级下册英语unit7的重要语法是什么

1.表示礼貌请求的疑问句

Would you mind doing sth.?请你做……好吗?

这是征求对方意见?希望对方做某事的委婉说法,这样更容易为对方所接受,从而达到自己的目的,何乐而不为?

Would you mind opening the door?请你打开门好吗?

你看一下,比open the door是不是委婉得多?

【拓展】

类似的句式表达还有:

Could you do sth.?

Would you like to do sth.?

Would/Could you please do sth.?

其中would,could并不表示will,can的过去式形式,而是委婉语气的表达。

如果提醒对方不要做某事,可分别表示为:

Would you like not to do sth.?

Could you not do sth.?

Would you mind not doing sth.?

2.状语从句

英语的句子类型分为三种:简单句,并列句和复合句。从句与主句合在一起被称为复合句。在复合句中修饰主句中的动词、形容词和副词等的从句叫做状语从句。状语从句根据它表达的意思可分为时间、地点、原因、目的、结果、让步、比较、方式和条件状语从句。

本单元中出现了以if引导的条件状语从句,该从句修饰主句中的动词,表示该动作发生的前提条件。

需要引起注意的是,如果主句中的谓语动词为将来时,以if引导的条件状语从句则用一般现在时。看下面的例子。

We will have a meeting if it doesn’t rain.如果天不下雨,我们要开会。

If he comes,I will tell you.如果他来,我会告诉你的。

从以上例句中不难看出,以if引导的条件状语从句可以置于句子开头,通常与主句以逗号相隔,也可以放在主句后面。

❷ 英语八年级下册第七单元SectionB 2b翻译

8: At the Cheng Panda Research Base, Lin Wei and other panda keepers are preparing to feed the baby panda.

8:30在成都熊猫研究基地,林伟和其他熊猫饲养员正在准备给小熊猫喂奶。

At 9:00, they found that most of the pandas were awake and hungry. When the pandas see the keepers, they come over happily, some come to their friends, some turn over and roll over.

在9:00,他们发现大多数熊猫已经醒来、也饿了。小熊猫看见饲养员,它们就高兴地过来,有的向它们的朋友走过来、有的翻身滚过来。

"How cute and smart they are. I take good care of them like my own children. I bathe, feed and play with them every day. They have a special feeling for me. " Lin Wei likes her job, but it's also very difficult.

“它们多么可爱和聪明。我把它们像自己的孩子那样好好照看。我每天给它们洗澡、喂食和陪它们玩。它们对我有特别的感情。”林伟喜欢她的工作,但是这份工作也非常困难。

这部分内容主要考察的是情态动词的知识点:

本身有一定的词义,表示语气的单词。但是不能独立作谓语,只能和动词原形一起构成谓语。情态动词用在行为动词前,表示说话人对这一动作或状态的看法或主观设想。 情态动词虽然数量不多,但用途广泛,常见的有: can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would).

四大分类

①只做情态动词:may, might, must…

②可做情态动词又可做实义动词:如:need, dare.can...

③具有情态动词特征:have(had,has) to,used to, ought to

④可做情态动词又可作助动词:如:shall(should),will(would)

At the Cheng research base, at 8:30 a.m., Lin Wei and other panda keepers prepared milk for their cubs for breakfast. At 9 a.m., they found that most of the pups were awake and hungry. When these babies saw the keeper, they all rushed over with excitement. Some even climbed over their friends and fell down.

成都调研基地,上午八点半,林伟和其他的熊猫饲养员给熊猫幼崽准备了牛奶做早餐。上午九点,他们发现大部分幼崽已经睡醒并且感到饿了。这些小宝宝看到饲养员的时候,全部兴奋冲了过来,有些甚至从朋友们的身上爬过去还摔倒了。

They are so cute. I take care of them as my baby. Bathe, feed and play with them every day. They are very special to me. Lin loves her job, but it's not easy.

他们太可爱了。我把它们当成自己的宝宝来照顾。每天给它们洗澡,喂养和玩耍。它们对我来说非常特别。林伟爱她的工作,但是这工作并不容易。

Pandas can't have many babies, maybe only one every two years. Pups often die and cannot live long. Alt pandas spend about 12 hours a day eating 10 kilograms of bamboo.

熊猫并不能生很多宝宝,也许每两年只能生一个。幼崽们经常病死,不能活很长时间。成年熊猫每天大概花12个小时,吃掉10公斤的竹子。

Many years ago, there were many bamboo forests and pandas in China, but then people began to cut down bamboo forests. Scientists say there are fewer than 2000 giant pandas in the existing bamboo forest environment. About 200 pandas live in zoos or research centers in China and other countries.

许多年前,中国有许多竹林和熊猫,但之后人类就开始砍伐竹林。科学家们说在现存的竹林环境中,仅有不到2000只大熊猫。大约200只熊猫在动物园或中国和其他国家的研究中心生活。

An ecation project in Cheng aims to teach children in the city about giant pandas and other endangered animals. They sent people to school to tell the children the importance of protecting these animals. Children sing songs or make pictures about giant pandas and other wild animals.

成都的一个教育项目旨在向城市的孩子教授大熊猫和其他濒危动物的知识。他们派人到学校告诉孩子们保护这些动物的重要性。孩子们唱歌或者制作有关大熊猫和其他野生动物的图片。

Ecating children is a way to help save pandas. The Chinese government has also planted more bamboo forests, so there will be more bamboo forests for pandas to live in. We all hope there will be more pandas in the future than they are now.

教育孩子是帮助拯救大熊猫的一种方法。中国政府也种植了更多的竹林,因此将会有更多的竹林供熊猫居住。我们都希望将来会有比现在更多的大熊猫。

这部分内容主要考察的是间接引语的知识点:

用在表述意见的动词perception 之后的一种从句,这种从句并非由主语直接叙述出来,而是通过第三人转述的。实际上间接引语大都是宾语从句,当直接引语为祈使句,陈述句,疑问句被转换成间接引语时,句子的结构,人称,时态,时间,时间状语和地点状语等都要发生改变。间接引语其实就是我们所说的第三人称转述。

主句动词认为:sentiunt ,时态是现在时。间接引语中的动词是不定式 liberandos esse,是将来时,因为“被释放”的动作是发生在主句动词“认为”之后的。liberandos 的性(阳性)、数(复数)与间接引语的主语servos 保持一致。
