• After the verb wish in sense 1, a past tense is always used in a that clause. 动词 wish 作第 1 义时，后面的 that 从句总是用过去时：◆Do you wish (that) you had a better job? 你希望有个更好的工作吗？ In more formal English, especially in NAmE, many people use were after I, he, she, it instead of was. 在更正式的英语，尤其是美式英语中，许多人在 I、he、she、it 之后用 were，而不用 was：◆I wish he were here tonight. 要是他今晚在这儿就好了。
