恩,主要是时态。BEFORE 一般用在完成时是吧?AFTER 呢? 同位语昨天的内容,今天咱们看看代词的指代 43. In the minds of many people living in England, before Australia was Australia, it was the antipodes, the opposite pole to civilization, an obscure and unimaginable place that was considered the end of the world. (A) before Australia was Australia, it was the antipodes (B) before there was Australia, it was the antipodes (C) it was the antipodes that was Australia (D) Australia was what was the antipodes(A) (E) Australia was what had been known as the antipodes A,B 中的IT 各自指代谁?A:Australia---it B:THERE ---IT ???
50. As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally blind if it were an adult with such vision. (A) As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally blind if it were an adult with such vision. (B) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500, or legally blind as an adult. (C) As a baby emerges from the darkness of the womb, its rudimentary sense of vision would be rated about 20/500; qualifying it to be legally blind if an adult. (D) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500; an adult with such vision would be deemed legally blind.(D) (E) As a baby emerges from the darkness of the womb, its rudimentary sense of vision, which would be deemed legally blind for an adult, would be rated about 20/500. A 中的IT 指代的是BABY 。 以前GEMJ 说过,从句的主语代词优先指代主语。 那咱们能不能说,主句的主语代词优先指代从句的主语????????????? 另外,好像IT 突然出现在句首,除了强调句和形式主语外,都是错的。 IT 出现在后半句表示指代的时候,还可能对。 44.

(D) By the twelfth week of pregnancy, fetal heartbeats can be detected using a Doppler ultrasound device by a physician.(E) (E) Using a Doppler ultrasound device, a physician can detect fetal heartbeats by the twelfth week of pregnancy. D 中的USING 修饰的是谁???-ING 分词放句中(前后没有逗号) 可以肯定是做定语不是状语的。 那么,他是修饰谁呢???虽然它用错了,但是我还想知道 |
