  英语第一单元知识点

  1. Choosing what to eat is no longer as easy as it once was.

  我们在选择吃的东西方面,现在不像过去一样简单了。

  [问]as在此处作何解释?

  [答]作连词,表示比较。又如:My hometown is no longer the same as it was. 我的家乡同过去不一样了。

  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. 如果我们要跟上现代生活的步伐,我们最好学会正确的选择吃什么以及怎么吃。

  [问]如何分析此句?

  [答]这里if引导的是条件状语从句,we had better ...是主句,what and how we eat 是宾语从句做about的宾语。keep up with 赶上,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. 当我们选择我们想要买和想要吃东西的时候,我们最好想一想这些食物是否提供了我们所需要的 营养。

  [问]这个句子中有三个从句,对吗?

  [答]对。when..., 是时间状语从句;if...是宾语从句;we need是定语从句。

  4. Some nutrients help build our body and amke it stronger. 一些食物有助于我们增强体魄。

  [问]build our body and make it stronger 一起做help的宾语吗?

  [答]是的。

  5. Caicium, which is found in eggs, milk and other dairy products, is good for our bones and teeth.

  [问]which is found in eggs, milk and other dairy product 是定语从句吗?

  [答]是的。而且引导词which在从句中作主语,代替calcium。

  6. Other nutrients help keep our body functioning well. 其他的营养物有助于我们的身体正常运转。

  [问]function在这里作动词吗?

  [答]是的。在这里“起作用”等的意思。

  7. But the choices we make are not just about nutrion. 但是,我们做出的选择不仅是营养方面的。

  [问]we make 又是定语从句?

  [答]是的。make choices 是“作出选择”的意思。引导词which/that 作宾语,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.

  饮食习惯成了我们信仰中不可分割的部分;素食主义者有的认为不吃肉身体要更健康些,有的则是不主张杀动物为食者。

  [问]这么长的句子,怎么分析?

  [答]主句是:Eating habits become part of who we are. Eather..., or... 引导两个because 原因状语从句。

  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. 我们对产品的作出的选择还决定于生产和加工方式,要是环保性的或者说是生态性的食物,是厂家用绿色而又清洁的方式生产出来的食物。

  [问]此句是否定语从句中套定语从句。

  [答]对。that are grown without chemicals 做vegetables 的定语;that can be harmful to human beings and the environment 做chemicals 的定语。

  11. If our diet includes foods from all the food groups, in the right amounts, we so not have to buy any supplements. 如果我们食物品种多,数量恰当,我们就不需要买任何补给品。

  [问]请解释此句中的if结构和do not have to 相当与need't。

  12. The same goes for "crash diets" that some companies say will make us lose weight fast. 对于一些公司所宣称可以让我们减肥的减肥餐也如此。

  [问]that some companies say will make us lose weight fast 起什么作用?

  [答]定语从句。that 在从句中作主语代替“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. 我们不需要去吃那些昂贵的固定饮食或者不健康的饮食, 只需要少吃脂肪和糖, 多锻炼就行了。

  [问]请问intead of 介词短语?

  [答]instead of 是介词短语, 表示“代替”的意思。

  14. The best way to make sure that we will feel and look fine is to develop healthy eating habits. 保健的最好方式是养成健康的饮食习惯。

  [问]这句话的主句究竟是什么?

  [答]The best way is to develop healthy eating habits 是这句话的主句 to make sure that we will feel and look fine 不定式短语做定语, 修饰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.

  我们应该更多地了解自己的身体以及我们身体所需的养料, 以便我们对生活中所面临的机遇和挑战有充分的准备。

  [问]so that 是什么意思?

  [答]so that 是“以便”的意思,常引导结果状语从句。

  16. That means that sandwich or a salad is a good choice, but a chocolate bar or a bag of patato chips is not. 也就是说,要选择三明治和色拉之类的而不是选择巧克力和炸土豆条。

  [问]如何分析此句句子 成分?

  [答]“That" 是主语, “mean" 是谓语, 后面整个that引导的两个并列从句是宾语,第二个从句“is not" 后省略了a good choice.
