重點句型與高考
1. it took more than two decades, though, until 1951, for colour broadcasts to begin in the usa.
  a. it takes sb. some time to do sth. 此句型表示“某人做某事需花費多少時間”。句中take表示“花費”。 如：
1) _______ environmental damage is done, it takes many years for the
ecosystem (生態系統) to recover.
a. even if       b. if only               c. while     d. once
答案d。一旦環境被破壞，生態系統需要經歷多年才能恢復正常。
    b.句中 though是副詞，表示“然而”，通常用于句末。如：
1）---you do not seem to be quite yourself today. what is wrong?
---oh, i am suffering from a cold. nothing serious,______
a. though  b. indeed   c. anyhow  d. yet
答案a。這個題目考察的是though的用法，意思是“我感染了感冒，但是不嚴重”。though作副詞，表轉折，相當于however,一般放在句末。也就是說，這里的though是副詞，副詞一般用于句末,而做連詞的時候，一般不用于句末。yet在表示雖然，但是的時候，是連詞，而不是副詞 。
2. it is reported that in 1998,66 per cent of households in the usa had cable tv.
  it is reported that…為固定句型，表示“據報道,…”，其中it為形式主語，that引導主語從句。此種句型常可轉換為“as is reported,…”。或“ sb. is reported to…”如：as is reported , in 1998, 66 per cent of households in the usa had cable tv. 或 66 per cent of households in the usa are reported to have had cable tv in 1998.
類似的句型還有以下一些：　　it is reported that …    　　   it is said that …
　 it is thought that …         　　it is considered that…       如：
 1）leonardo da vinci (1452 - 1519) ________ birds kept in cages in order to have the pleasure of setting them free. [ 重慶卷]
