It is also ②what drives scientists to constantly push the boundaries of human knowledge. Moreover, scientific exploration is ③where new technologies and innovations are born. The doubt in many people’s minds is ④whether there is life on other planets. Another mystery scientists often study is ⑤why some species evolve faster than others. A key focus of medical research is ⑥how we can develop better treatments for diseases. What remains unclear sometimes is ⑦which approach will work best in complex experiments. 【自主发现】 以上语段中,①、②、③、④、⑤、⑥、⑦句均为　　　从句;其中that,whether为　　　　,在从句中不作成分;what,which为　　　　　　;where,why,how为　　　　　　。  Predicative clauses (表语从句) 在复合句中,位于系动词之后作表语的从句叫作表语从句。表语从句常用以下引导词: 类别 例词 说明 从属 连词 that, whether 两者在从句中都不作成分,that无实义,whether意为“是否”,通常不能用if替换 连接 代词 who, whose, what, which等 在从句中作主语、宾语、表语、定语 连接 副词 when, why, where, how 在从句中作时间、原因、地点、方式状语 其他 连接词 because 主句主语不用reason as if/ as though 表语从句表示的情况发生的可能性较小时常用虚拟语气 如:The most important thing is that we should find enough water for the sheep. 最重要的事是我们应为羊找到足够的水。 The doubt is who has taken away the valuable painting. 疑问是谁拿走了那幅珍贵的画。 The black clouds are gathering. It looks as if it is going to rain. 乌云正在聚集。天看起来好像要下雨了。 注意: 1.that,why,because引导表语从句的区别: (1)表示原因的名词(reason,cause)作句子主语时,其后的表语从句常用that引导,不可用because。 如: The reason why he was late was that he missed the first bus this morning. 他迟到的原因是他今天早晨错过了首班公共汽车。 (2)because引导的表语从句常用于“That’s because…”结构中,说明产生上述结果的原因,表示前果后因;why引导的表语从句说明由上述原因导致的某种结果,表示前因后果。 如: I was late for school this morning. That’s because I stayed up too late last night. (果→因) 今天早晨我上学迟到了,那是因为我昨晚熬夜太晚了。 I stayed up too late last night. That’s why I was late for school this morning. (因→果) 我昨晚熬夜太晚,那就是我今天早晨上学迟到的原因。 2.表语从句中的虚拟语气 当主语是表示“建议、命令、要求、计划”(suggestion,advice,proposal,order,command,request, requirement, demand, plan)等的名词时,表语从句应该用虚拟语气,即从句谓语用“should+动词原形”形式,should可以省略。 如: My suggestion is that we (should) set off early tomorrow. 我的建议是我们明天早点儿动身。 【实战演练】 ●Ⅰ 单句填空 1.I didn’t see the film last night.
