Betty 认为树木可以改善空气质量。 有一点要提醒同学们：并非所有的动词后面都可接that引导的宾语从句。常接that引导的宾语从句的谓语动词有：believe，expect，explain，feel，hear，hope，imagine，prefer，promise，report，say，see，tell，think，understand，warn，wish等。","I hope (that) it will snow this winter.",{"t":269,"c":270,"eg":271},"whether \u002F if","引导的宾语从句 如果我们要表达 \"他不知道他们周六是否会去植树\" 或 \"我记不清以前是否见过他\" 这样的不确定的概念时，从句就要用 whether 或 if 来引导，不能用 that。 例如： 他不知道他们周六是否会去植树。 他问我们星期天是否会去钓鱼。 想知道他明天是否需要早来。 同学们可能会问，这里有两个引导词，一个是whether，一个是if，应如何选择呢？在宾语从句中没有or not的情况下，一般来说两个词都可以用。如果从句中有or not的话，一般就要选择whether，构成whether... or not的结构。","He does not know whether they will plant trees on Saturday or not.",1787063544344]
