重点句型与高考
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“某人做某事需花费多少时间”。句中take表示“花费”。 如：
1) _______ environmental damage is done, it takes many years for the ecosystem (生态系统) to recover.
A. Even if B. If only C. While D. Once 答案D。一旦环境被破坏，生态系统需要经历多年才能恢复正常。 B．句中 though是副词，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。这个题目考察的是though的用法，意思是“我感染了感冒，但是不严重”。though作副词，表转折，相当于however,一般放在句末。也就是说，这里的though是副词，副词一般用于句末,而做连词的时候，一般不用于句末。yet在表示虽然，但是的时候，是连词，而不是副词 。
