| 释义 | 〔bust〕To render inoperable or unusable:破坏，使失败：使不能运作或不能使用：〔can〕since it requires the pupil to distinguish explicitly between what is possible and what is allowed,a difference not always apparent to younger children.And even in later life,observance of the distinction is often advisable in the interests of clarity.Thus, the sentenceStudents can take no more than three courses allows the possibility that a student who is unusually capable may take more, whereasStudents may take no more than three courses does not. · The use ofcan to express permission is better tolerated in negative questions, as inCan't I have the car tonight? probably because the alternative contractionmayn't is felt to be awkward. 由于这要求学生清楚地区分可能的和得到许可的两者之间的差异，而这对小孩子们常常是不太明显的。并且在其今后的生活中，为明确起见，体会这种差异常常是很可取的。因此，句子学生们可以选修不超过三门的课程 给能力超常的学生学更多的课程提供了可能性， 然而学生们只能选修不超过三门的课程 则不能提供这种可能性。 can 的用法更可用于否定疑问句中表示许可， 如 我今晚不能使用这车吗？ ， 或许是由于可替代的缩写mayn't 感觉起来有些笨拙的缘故 〔if〕Again according to the traditional rule,the subjunctive is not correctly used following verbs such asask or wonder in if clauses that express indirect questions, even if the content of the question is presumed to be contrary to fact: 另外还是根据传统规则，在动词ask 或 wonder 中 if 引导的间接问句， 即使其内容被认为与事实相反，也不能使用虚拟语气： 〔close〕To surround so as to make unusable:笼罩：围绕使不能使用：〔infinite〕Infinite is sometimes grouped with absolute terms such asunique, absolute, and omnipotent, since in its strict mathematical sense it allows no degree modification or comparison;one quantity cannot be more infinite than another (though technically one infinite set can be larger than another).Unlike other absolute terms, however,infinite also does not permit modification by adverbs such as nearly and almost; mathematically, infinity is not approached by degrees.In nontechnical usage, of course,infinite is often used metaphorically to refer simply to an unimaginably large degree or amount, and here the comparison of the word is unexceptionable: Infinite 有时被一些表示绝对意义的词修饰， 如unique ， absolute 和 omnipotent ， 由于在其严格的数学意义上它不允许表示程度的修饰或比较，一个数不可能比另一个数“更加无穷大”（虽然以技术上讲一个无穷集可以比另一个集更大）。但是，与其它表示绝对意义的词不同，infinite 也不能用 nearly 和 almost 这一类副词来修饰； 以数学上讲，无穷大是不能逐步接近的。当然，在非技术性的用法中，infinite 常常隐喻地仅指明一个难以想象的大程度或数量， 在这种用法下，仍然不能使用比较： |
