ashamed和shameful区别
意思和用法的不同:一般来说,ashamed是指人感情上感到惭愧、内疚,强调feel,不修饰名词;而shameful多用来修饰行为的可耻。例:He ought to be ashamed of himself。It's a shameful behavior/secret。It's a shameful secret/behavior。
as if 的用法
一、as if 从句的作用
1.在look, seem 等系动词后引导表语从句。如: She looks as if she were ten years younger. 她看起来好像年轻了十岁。 It seems as if our team is going to win. 看来我们队要胜了。
2.引导方式状语从句。如: She loves the boy as if she were his mother. 她爱这男孩,就好像她是他的母亲一样。 The child talked to us as if he were a grown?up. 那孩子跟我们谈起话来,像个成年人似的。
二、as if 还可用于省略句中
如果as if 引导的从句是“主语+系动词”结构,可省略主语和系动词,这样as if 后就只剩下名词、不定式、形容词(短语)、介词短语或分词。如: He acts as if (he was) a fool. 他做事像个傻子。 Tom raised his hands as if (he was going) to say something. 汤姆举起手好像要说什么。 She left the room hurriedly as if (she was)angry. 她匆忙离开房间好像生气的样子。
三、as if 从句的语气及时态
1. as if 从句用陈述语气的情况。 当说话者认为句子所述的是真实的或极有可能发生或存在的事实时。如: It sounds as if it is raining. 听起来像是在下雨。 He talks as if he is drunk. 从他谈话的样子来看他是醉了。
