onlyif倒装句的用法例句
only if表示"只有...才..."。当only if放在句首时,应该用倒装句型。所谓倒装句型,就是将句子中的"助动词"提前。
例句:Only if presented in this way can your idea get over to the audience.
扩展资料
Only if 条件从句在前,中间无逗号时主句要倒装。
例句:
Only if I get a job will I have enough money to go to school.
我只有找到了工作才有足够的钱上学。
Only if a teacher has given permission is a student allowed to enter this room.
只有得到教师的允许,学生才可以进这间屋。
若置于句首的only if不强调“唯一性”或“排他性”,比如当其中的only表示just或as recently as等意思时,此时其后的'句子则不用倒装。
例句:
Our prices are in force only if you order by return mail.
