Answer 1

分析 當(dāng)他班主任拍他的頭時(shí)，他正在唱那首You don't know love，F(xiàn)ar High between classes．

解答 答案：B
考查句子時(shí)態(tài)，根據(jù)when引導(dǎo)的時(shí)間狀語(yǔ)從句可知，主句he當(dāng)時(shí)正在唱歌；根據(jù)when his head teacher patted…用一般過(guò)去時(shí)，所以確定主句時(shí)態(tài)為過(guò)去進(jìn)行時(shí)，結(jié)構(gòu)為was+doing．

點(diǎn)評(píng) 考察過(guò)去進(jìn)行時(shí)，考生要掌握該時(shí)態(tài)的特點(diǎn)，即在過(guò)去的某個(gè)時(shí)間點(diǎn)正在發(fā)生的動(dòng)作，結(jié)構(gòu)為was/were+doing．
