Here are the results. 这是一个倒装句在英语中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的用法：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”，在通常情况下，其中的名词是特指的，所以通常会带有定冠词the或其他表特指的限定词（如his, her, these, those, Tom’s等），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. Most students use it for fun and not for homework. for 此处意为“为了”例如:He came to Jim’s home for dinner.【拓展】介词for的用法:1）“对于，关于”例如:English is easy for him. 2） 做事“达到”多长时间，例如:I slept for 10 hours last night. 3） 表示目的，“为了”，例如:The girl bought a sweater for her mother. 4）表示原因，例如: Thanks for helping me. 4. 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。

例如:Although/though he is very tired, he doesn’t have a rest.【针对练习】_________they are brothers, they don’t look like each other at all. 5. such as的用法such as用来列举同类人或物中的几个例子，可置于被列举的事物与前面的名词之间，但其后边不能用逗号如:Boys such as John and James are very friendly.像约翰和詹姆斯这样的男孩都很友好针对练习】I like drinks (例如)tea and milk. 6.
