单项填空
An earthquake struck this area, a lot of damage. (2010•01•东青岛二中模块检测)
A.aking B. causing C. done D. Caused
解析:选B。make与damage不能搭配使用；“造成损失、损害”用do/cause damage；此处的动词与前面的句子构成逻辑上的主谓关系，所以需用现在分词作结果状语。
5. present
n.礼物；目前
adj.在场;出席;当前的
v.颁发;授予;赠给
常用结构：
be present at 出席
the present day=today 今天
at present／at the present time＝now 现在
for the present=for the time being 暂时
the present 现在(相当于名词)
present sb. with sth=present sth. to sb. 把某物送给某人
present?day attitudes/fashion现在的态度/流行款式
联想拓展
present作动词，表示“给予，赠送”之意，常用于present sth.to sb.或present sb.with sth.搭配中，此外，present作动词还有“呈现，显示；阐述，表达；引见”等意思。
①作形容词既可作前置修饰语，也可作表语，常意为“现存的；现在的；在场的；出席的”等。
②作不可数名词时，表示区别于过去或将的“现在”；作可数名词时，意为“礼物”。
The same problem presented itself to her again.
同样的问题又在她身上出现。
