二.语句层次
⒈否定句
㈢双重否定句
①其形式一为：主语+cannot+help/refrain/keep+from+动名词。Help from, refrain from, keep from等词具有“抑制，忍住”等否定含义，与cannot等连用，具有双重否定的意义。
例：Having won the gold medal,___________________(他禁不住喜形于色)。
答案：he could not refrain from showing his pleasure.
(本题考察双重否定句，refrain from的意思是“克制，避免”)
②其形式二为：主语+cannot+but/choose but/help but+动词原形。
例：_______________________(我们别无选择只好另投旅馆住宿)，
since all the hotels here are with signs “Be Booked Up”.
答案：We could not help but look for another one to stay in.
(本题考察双重否定句，“cannot help but”句型，注意这里but后要用动词原形。)
③其形式三为：(There be)no+主语+but+谓语。在此句型中，but是关系代词，即代替前面的名词，又引导后面的从句，并且具有否定意义。
例：He is so devoted to his experiment that______________________(没有人感觉不到他对事业的热爱)。
答案：not a man/no man but felt his love to his career
(本题考察双重否定句型，“no+主语+but+谓语”，no相当于not a 或 not any)

2.______________________(人们不能不被他的事迹所感动)after knowing the bachelor has adopted five orphans.
