2. because 可以引导表语从句,而 as, since 不可以，这时主语一般都是 it, this, that 3. since 往往表示的是已知的客观事实，或分析后的推理，引导的从句大多置于句首，主从 句的时态一般相同。 for 可做并列连词，不可用于句首，要放句中，引导后半句表原因，强调推理解释。 反馈训练三：用 because, as, since 填空 It was ________ he was ill that he didn’t go with us. It’s_________ he is too lazy. _______you are here, you must do it. 2． 复合连词也可以引导原因状语从句， 这些连词有： now that, seeing (that), considering (that), for the reason that, by reason that, for fear that, in that 等， Eg: 1).

There was such delicious food that he had too much. 3. so that 引导结果状语从句表示实现的一件事或一个事实，从句谓语动词一般不和情态动 词连用，且从句前多有逗号与主句分开。例如： She hurried, so that she caught the bus.(结果） She hurried so that she might catch the bus. （目的） 反馈训练四: 用 so that/ so…that…/such…that… 填空： 1.He studied hard ________ he passed the exam. 2.He was _____ angry ______ he couldn’t speak. 3.

Hard as you may try，you will not succeed. 尽管你努力了，你可能不会成功。 (2)如果从句的谓语部分为 “情态动词＋不及物动词” ， 常将这个不及物动词提到从句的句首。 Wait as you may，he will not see you. 尽管你等了，他可能不会见你。 (3)如果从句的谓语部分是“系动词＋单数名词” ，则常将这个作表语的名词提前，但这个名 词前面的不定冠词要省略。 Child as he is，he can tell right from wrong. 尽管他还是个孩子，他能明辨是非。 3.whether...or (not) ...不管??还是??。 Eg: 不管你相信与否，这是真的。 Whether you believe it or not, it's true. 反馈训练五： 1.
