10、的方式来询问信息，温柔的发号施令或要求某人做某事。我们用附加疑问句来询问意见或征求同意。当我们用附加疑问句来询问意见时，为了期待对方能同意我们的观点，附加疑问句会用降调来表达。当我们用附加疑问句来征求同意时，我们实际上是在询问我们自己也不太能确信的事情，这时候附加疑问句会用升调来表达。2 .附加疑问句的构成有以下几种：1）在肯定的陈述句之后，我们会用否定的附加疑问句。在否定的陈述句之后，我们会用肯定的附加疑问句。如：Wecanstillbefriends,can'twe?Hedoesntlikeicecream,doeshe?2）当主句中有像neither,none,nobody,no

44、ything/nobody/no时，动one/nothing/somebody/someone/something/each/eachone/either/neither/one词用单数。牛津高中英语一模块四第一单元一直接引语和间接引语1 .我们用直接引语来阐述所说的话。如果我们把引语写下来，这些单词就会被放在引号但是，我们通常更愿意用间接引语来阐述所说的话。直接弓I语：Shesaid,“ChinahasbeenusingPSAstoeducatepeople.”间接弓I语：ShesaidChinahadbeenusingPSAstoeducatepeople.2 .我们可以通过把所说的话改成

45、宾语从句或动词不定式短语的形式来把直接引语变成间接引语。如：Shesaid,Tmusedtoads.”Shesaidthatshewasusedtoads.“Wemustnotfallforthiskindoftrick!”shesaid.Shewarnedusnottofallforthatkindoftrick.3 .除了句型的改变外，还有其它的改变：1）人称代词的改变：如：Shesaid,“Ididsomeresearch.”Shesaidthatshehaddonesomeresearch.2）时态的改变:如：Shesaid,“Thisasisveryclever.”Shesaidth
