释义 | 1.I have no doubt that he will come soon 和 I have no doubt he will come soon 都可以说。 2.可以说There is no doubt that he will come soon,不可说It is no doubt that he will come soon。 There is no doubt about it that he will come soon. =There is no doubt that he will come soon. 3.doubt(动词)除了在否定句和疑问句里以外,后面通常接 whether 而不接 that,如通常说 I do not doubt that he will come soon 和 Do you doubt that he will come soon? 但不说 I doubt that he will come soon。最好把 that 改作 whether。doubt 用作名词也有这区别,如通常说 There is no doubt that he will come soon 和 Is there any doubt that he will come soon? 但不说 There is some doubt that he will come soon。最好把 that 改作 whether。 4.在上面说过,I doubt that he will come soon 里的 that 最好改作 whether。用了 that,不但不合习惯,而且往往有可能被人误解,因为在旧式些的英语里 doubt that...作“恐怕……”或“料想……”解。 5.I doubt whether he will come soon 含有“我想他不会不久就来”的意思,I doubt whether he will not come soon 含有“我想他不久就来”的意思。 6.no doubt 是状语短语,现在作“当然”或“大约”解,没有“确实无疑”那样的坚信的意思,如 No doubt he meant well enough 和 You have no doubt heard of her before。要表示“确实无疑”的意思,该用 undoubtedly,without doubt,without a doubt,beyond doubt 或 beyond a doubt。 7.in doubt 有时作“怀疑的”解,有时作“使人怀疑的”解,如 I am in doubt about his age 和 His age is in doubt。在用作“怀疑的”解的时候,后面往往不用介词而直接以 what,where,how 等开首的短语或从句。例如: I am in doubt what to do with it. I am in doubt where he lives. I am in doubt how to proceed. 8.I have no doubt about it 和 There is no doubt about it 等句子里用单数形式 doubt,但 I have doubts about it 里必须用复数形式。 |
