when為并列連詞，意為“正在這時(shí)，突然……”相當(dāng)于and then, just at this time。常用于以下句型：
sb+was/were doing sth.+when… 某人正在做某事，這時(shí)……。 sb be about to do/be on the point of doing sth when… 某人正要做某事時(shí)，這時(shí)……。sb had just done when… 某人剛做完某事，這時(shí)……。
hardly……when…; no sooner…than…… 剛…就…（主句常用過去完成時(shí)/從句用一般過去時(shí)態(tài)）
另：when還可引導(dǎo)狀語從句==now that，表示“既然；考慮到”。
既然你可以走到那兒，為什么要打的呢？why did you take a taxi when you could have walked there?
while除了有“當(dāng)/在……時(shí)候”的意思外，另外的兩層意思也是考查的重點(diǎn)：
（1）while = although “盡管”、“雖然”，引導(dǎo)讓步狀語從句,句首；（2）while的意思是“然而；可是”，常用來表達(dá)對(duì)比關(guān)系。
盡管我承認(rèn)這個(gè)問題很難，但是我并不認(rèn)為無法解決。while i admit that the problem is difficult, i don’t think that they can’t be solved.
