1．Too much smoking and drinking________him greatly，which meant bad living habits had an________on his health.
A．affect；effect B．affected；effect
C．affected；effects D．affect；effects
解析 affect为及物动词“影响”；effect为名词。另外have an effect on为固定搭配，意为“对……有影响”，故选B项。
答案 B
2．The fact that so many people still smoke in public places______that we may need a nationwide campaign to raise awareness of the risks of smoking.
A．suggest B．suggests
C．suggested D．suggesting
解析考查时态和主谓一致。句意：有许多人依旧在公共场合吸烟，这一事实表明我们也许需要搞一次全国性的活动来提高人们对于吸烟危害性的认识。the fact后跟同位语从句，设空处为主句的谓语动词，故排除D项；由题干中的smoke和may等可知语境指现在的情况，故排除C项。本句主语为the fact，且本句陈述的是一个事实，故谓语动词应采用第三人称单数形式，故选B项。
答案B
3．They receive a proportion of their________from the sales of goods and services.

解析 income意为“收入”；pay意为“工资，薪水”；wage意为“按日或周所发的工资”；expense意为“花费；消费”。根据句意应选A项。
答案 A
