(P28)disappointed adj. “失望的;失意的;受挫的”,可在句中作表语、定语或宾补。be disappointed at / about“对感到失望”;be disappointed with“因为而失望”。disappointed是由动词disappoint的过去分词形式演变而来,一般有被动意义。
2、 eg: He was disappointed to hear they were not coming.disappointing adj.“令人失望的”,主语常是物或事,有时可用于最高级,如most disappointing,是由disappoint的现在分词演变过来的。可见-ing形容词和-ed形容词都是由其相应的动词转换而来的,这样的动词还有如amaze,bore,excite,exhaust, interest,satisfy,surprise,tire等。 The disappointing news made us disappointed.“That was very ex

5、e closed the gate to prevent the dog from going out of the garden.该短语的同义词组有stop from doing和keepfrom doing,三个短语意思一样,但prevent和stop可以省略from,keep后面不能省略from,如果省略了,意思就发生了变化。如: The boss kept the workers from having a rest. 老板不让工人们休息。The boss kept the workers working day and night. 老板让工人们夜以继日地工作。3.

6、life will continue on the earth for millions of years to cine will depend on whether this problem can be solved.

10、ther“是否”,表示一种不确定的因素;连接代词what“的东西;事情”,可在从句中作宾语、定语和表语;who仍有疑问的意思“谁”,在从句中作主语;which“哪个”,在从句中作定语或主语;连接副词where“哪里”;why“为什么”;how“怎样”;when“何时”,在从句中作状语。四、it作形式主语主语从句过长时可用it作形式主语,that引导的真正的主语放在后面,且从属连词that可以省略。 eg: It is well-known that the earth moves around the sun.五、whatever / whoever / whichever的功用 whatev
