10．My father decided ________．My mother and I are glad about it．（ ）| A． | not smoke | B． | didn't smoke | C． | not to smoke |
分析 我爸爸决定不抽烟了．妈妈和我对此感到很高兴．
解答 答案：C．在一些动词的后面需要用动词不定式来作动词的宾语，decided的意思是"决定"后面需要用动词不定式来作宾语，也就是需要用decide to do sth．的形式．还要注意动词不定式的否定式是在不定式的前面加not，也就是not+to do．根据"My father decided ________"可知空格处需要用不定式，结合给出的选择项，需要用否定式，不定式的否定式是在不定式前面加not，也就是：not+不定式．综上所述，故选C．
点评 首先要掌握结构"动词+不定式"的基本用法，还要掌握经常可以用于这个结构的动词，比如want，decide，intend，fail，wish，export，pretend等等．还要掌握不定式的否定式，然后结合具体的题目，就可以确定正确答案．

An AIDS （艾滋病）understanding program in Yunnan was started six years ago．It was held by the Chinese Red Cross．The program is a great way of making sure that people learn the facts about HIV/AIDS．It is so successful that it is running in several other provinces now．
The program not only provides care and support for the people who carry HIV/ADIS virus（病毒），but also trains young people to teach others about HIV/ADIS．In the program，the volunteers hold two-day classes to teach people about the virus and its links（相关）to drug use and sexual practices．They also work with students，drug（毒品）users and people who may be at risk of becoming infected（感染）by the virus．
The organizers of the program said that people knew about HIV/ADIS and how it was spread after taking part in it．HIV/ADIS was found mainly among drug users and those who had become infected through careless blood transfusion（输血）practices．Today，the number of young people becoming infected through sexual activity is increasing，so it is important to deal with this big problem．
The Chinese government predicts that unless action is taken right now，as many as 10million people could be infected with HIV/ADIS in China in the next nine years．
In June 2001，the Chinese central government announced a five-year plan for dealing with the spread of the disease（疾病）．This plan focuses on better education about the virus，a national system to report cases of the disease and better practices for collecting blood．
