英語(yǔ)第一單元知識(shí)點(diǎn)
1. Choosing what to eat is no longer as easy as it once was.
我們?cè)谶x擇吃的東西方面,現(xiàn)在不像過(guò)去一樣簡(jiǎn)單了。
[問(wèn)]as在此處作何解釋?
[答]作連詞,表示比較。又如:My hometown is no longer the same as it was. 我的家鄉(xiāng)同過(guò)去不一樣了。
2. if we want to keep up with the high pace of modern life, we had better learn to make the right choices about what and how we eat. 如果我們要跟上現(xiàn)代生活的步伐,我們最好學(xué)會(huì)正確的選擇吃什么以及怎么吃。
[問(wèn)]如何分析此句?
[答]這里if引導(dǎo)的是條件狀語(yǔ)從句,we had better ...是主句,what and how we eat 是賓語(yǔ)從句做about的賓語(yǔ)。keep up with 趕上,跟上,had better最好。
3. When we choose what to buy and eat, we had better think if the food will give us the nutrients we need. 當(dāng)我們選擇我們想要買(mǎi)和想要吃東西的時(shí)候,我們最好想一想這些食物是否提供了我們所需要的 營(yíng)養(yǎng)。
[問(wèn)]這個(gè)句子中有三個(gè)從句,對(duì)嗎?
[答]對(duì)。when..., 是時(shí)間狀語(yǔ)從句;if...是賓語(yǔ)從句;we need是定語(yǔ)從句。
4. Some nutrients help build our body and amke it stronger. 一些食物有助于我們?cè)鰪?qiáng)體魄。
[問(wèn)]build our body and make it stronger 一起做help的賓語(yǔ)嗎?
[答]是的。
5. Caicium, which is found in eggs, milk and other dairy products, is good for our bones and teeth.
[問(wèn)]which is found in eggs, milk and other dairy product 是定語(yǔ)從句嗎?
[答]是的。而且引導(dǎo)詞which在從句中作主語(yǔ),代替calcium。
6. Other nutrients help keep our body functioning well. 其他的營(yíng)養(yǎng)物有助于我們的身體正常運(yùn)轉(zhuǎn)。
[問(wèn)]function在這里作動(dòng)詞嗎?
[答]是的。在這里“起作用”等的意思。
7. But the choices we make are not just about nutrion. 但是,我們做出的選擇不僅是營(yíng)養(yǎng)方面的。
[問(wèn)]we make 又是定語(yǔ)從句?
[答]是的。make choices 是“作出選擇”的意思。引導(dǎo)詞which/that 作賓語(yǔ),可以省去。
8. Eating habits become part of who we are: people become vegetarians either because they believe it is healthier not to eat meat or because they so not think we should kill animals for food.
飲食習(xí)慣成了我們信仰中不可分割的部分;素食主義者有的認(rèn)為不吃肉身體要更健康些,有的則是不主張殺動(dòng)物為食者。
[問(wèn)]這么長(zhǎng)的句子,怎么分析?
[答]主句是:Eating habits become part of who we are. Eather..., or... 引導(dǎo)兩個(gè)because 原因狀語(yǔ)從句。
9. We also make choices based on how the products are grown or made: environmentally friendly foods, or "eco-foods", are made by companies who have tried to use green and clean ways to make the foods. 我們對(duì)產(chǎn)品的作出的選擇還決定于生產(chǎn)和加工方式,要是環(huán)保性的或者說(shuō)是生態(tài)性的食物,是廠家用綠色而又清潔的方式生產(chǎn)出來(lái)的食物。
[問(wèn)]此句是否定語(yǔ)從句中套定語(yǔ)從句。
[答]對(duì)。that are grown without chemicals 做vegetables 的定語(yǔ);that can be harmful to human beings and the environment 做chemicals 的定語(yǔ)。
11. If our diet includes foods from all the food groups, in the right amounts, we so not have to buy any supplements. 如果我們食物品種多,數(shù)量恰當(dāng),我們就不需要買(mǎi)任何補(bǔ)給品。
[問(wèn)]請(qǐng)解釋此句中的if結(jié)構(gòu)和do not have to 相當(dāng)與need't。
12. The same goes for "crash diets" that some companies say will make us lose weight fast. 對(duì)于一些公司所宣稱(chēng)可以讓我們減肥的減肥餐也如此。
[問(wèn)]that some companies say will make us lose weight fast 起什么作用?
[答]定語(yǔ)從句。that 在從句中作主語(yǔ)代替“crash diets"。
13. Instead of eating expensive diet foods or going on unhealthy diets, we can simply try to eat less fat and sugar and exercise more. 我們不需要去吃那些昂貴的固定飲食或者不健康的飲食, 只需要少吃脂肪和糖, 多鍛煉就行了。
[問(wèn)]請(qǐng)問(wèn)intead of 介詞短語(yǔ)?

14. The best way to make sure that we will feel and look fine is to develop healthy eating habits. 保健的最好方式是養(yǎng)成健康的飲食習(xí)慣。
[問(wèn)]這句話(huà)的主句究竟是什么?
[答]The best way is to develop healthy eating habits 是這句話(huà)的主句 to make sure that we will feel and look fine 不定式短語(yǔ)做定語(yǔ), 修飾the best way.
15. We ought to learn more about our body and the fuel it needs so that we can make sure that we are well prepared for the challenges and opportunities in life.
我們應(yīng)該更多地了解自己的身體以及我們身體所需的養(yǎng)料, 以便我們對(duì)生活中所面臨的機(jī)遇和挑戰(zhàn)有充分的準(zhǔn)備。
[問(wèn)]so that 是什么意思?
[答]so that 是“以便”的意思,常引導(dǎo)結(jié)果狀語(yǔ)從句。
16. That means that sandwich or a salad is a good choice, but a chocolate bar or a bag of patato chips is not. 也就是說(shuō),要選擇三明治和色拉之類(lèi)的而不是選擇巧克力和炸土豆條。
[問(wèn)]如何分析此句句子 成分?
[答]“That" 是主語(yǔ), “mean" 是謂語(yǔ), 后面整個(gè)that引導(dǎo)的兩個(gè)并列從句是賓語(yǔ),第二個(gè)從句“is not" 后省略了a good choice.
