Although/Though it was so cold,he went out without an overcoat.尽管天气很冷,但他还是没有穿大衣就出去了。 【注意】 although=though用作连词,意为“虽然,尽 管”,这两个词都不能与but连用,即用了although/though 就不能再用but。不过although可以与yet/still一起使用。 尽管他身体不好,但是他工作很努力。 正:Although/Though he is in poor health,he works hard. 正:He is in poor health,but he works hard. 误:Although he is in poor health, but he works hard.

在英语中here, there放在句首时，句子通常用倒装语序。

例如:Here are the results of the math exam.【针对训练】Here________ the bus. (公共汽车来了)2：percent意为“百分之……”,没有复数形式，“数词+percent of+名词”意为“……当中的百分之多少”，作主语时，用它所修饰的名词来判断谓语的单复数。

如：Only fifteen percent of our students exercise every day.【针对训练】Sixty percent of students _________(be) 16 years old.3：Although many students like to watch sports, game shows are the most popular.although连词，意为“即使，纵然，虽然”，相当于though，在同一个句子中，although/though不能与but 连用。
