【语法精讲】
本模块的重点语法是含有实义动词的一般现在时态的特殊疑问句,其用法如下:
1. 疑问词+助动词(do或does)+主语+动词原形+其他?例如:
What do you use the computer to do?你用电脑做什么?
注意:在这一句式中,疑问词不作主语。
【典例】
— C do they usually play games?
—In the park near their home.
A. How B. What
C. Where D. When
解析:结合答语“在他们家附近的公园里”可知,问句问的是地点。故选C。
2. 疑问词+行为动词的第三人称单数+其他?例如:
Who uses the computer to play games?谁用电脑玩游戏?
注意:在这一句式中,疑问词作主语。
【典例】
—Who often A dinner in your family?
—My mother.
A. makes B. does C. making D. cooking
解析:根据often可知,句子使用一般现在时,主语是who,谓语动词使用第三人称单数形式,make dinner表示做饭。故选A。
