1. way作先行詞，意為“方式、方法”時，引導詞在從句中作狀語，可用that / in which 引導，也可省略；若引導詞作從句的主語或賓語，用that / which 引導，引導詞作賓語時可省略。
如：I‘ve thought of a good way （that / in which） we can conduct the experiment successfully. The way that / which will be used to carry out the operation was suggested by Doctor White. This is the very way （that / which） we need to test the theory.
2. 先行詞是time時，若表示“次數(shù)”，應用that引導定語從句，that可省略；若time表示“一段時間”，則用when或at / during which引導定語從句。
如：This is the second time （that） the President has visited the country. This was at a time when / during which there were no radios， no telephones or TV sets.
