2018年高考英語重難點總結(jié)
[問]此句是否定語從句中套定語從句。
[答]對。that are grown without chemicals 做vegetables 的定語；that can be harmful to human beings and the environment 做chemicals 的定語。
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)，我們就不需要買任何補給品。
[問]請解釋此句中的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. 對于一些公司所宣稱可以讓我們減肥的減肥餐也如此。
[問]that some companies say will make us lose weight fast 起什么作用？
[答]定語從句。that 在從句中作主語代替“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]請問intead of 介詞短語？
[答]instead of 是介詞短語， 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. 保健的最好方式是養(yǎng)成健康的飲食習(xí)慣。
[問]這句話的主句究竟是什么？
[答]the best way is to develop healthy eating habits 是這句話的主句 to make sure that we will feel and look fine 不定式短語做定語， 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， 以便我們對生活中所面臨的機遇和挑戰(zhàn)有充分的準(zhǔn)備。
[問]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，要選擇三明治和色拉之類的而不是選擇巧克力和炸土豆條。
[問]如何分析此句句子 成分？
[答]“that" 是主語， “mean" 是謂語， 后面整個that引導(dǎo)的兩個并列從句是賓語，第二個從句“is not" 后省略了a good choice.
三、本單元高考熱點歸納與拓展
[概述]
本單元重點語法是 had better，should 和 ought to 等情態(tài)動詞的用法。象其他的情態(tài)動詞一樣，had better， should 和 ought to 后面跟動詞原形。ought to 與 should 都表示“應(yīng)該”的意思。had better 表示“最好”的意思。如：you had better get some rest.你最好休息一會兒。you had better not eat fruit that isn't ripe. 你最好不要吃沒有成熟的水果。you should/ought to be careful with fruit. 你們應(yīng)該小心水果。you should not/ought to eat so much junk food. 你不應(yīng)該吃這么多垃圾食品。
