名词性从句是英语三大从句之一。包括四个分支：主语从句、宾语从句、表语从句和同位语从句。既然是复合句，也就是由两者或两者以上的句子复合而成。两句话合二为一的时候需要一个连接词。
最常见的连接词是that在宾语从句中的运用，如：I know that you will come. 句中的that 就是连接词，作用就是连接主句和从句，不充当成分也没有含义，只起风向标的作用，告诉你接下来的部分是一个整体，及that you will come 充当know 的宾语。
whether和if 也是引导名词性从句的连词，与that相同的地方是也不充当从句中的成分，但是是有含义的，“是否”。通常用于有疑问的句子，确定性。我们把that,whether, 和if 称为名词性从句连接词里的“3”。
名词性从句连接词里的“4”：where, when, why, how。此时从句中主谓宾这种主要成分都是不缺少的，缺少的是状语部分，如：I want to go to Walmart, but I don’t know_____ it is. 此时填where，缺少地点。
名词性从句连接词里的“5”：what,who, whom, which, whose. 缺成分指物用what；缺成分指人用who。
如：______ doesn’t does kill you makes you stronger. 填what 指事物。I don’tknow _____ took it away. 填who 指人。which 和 whose 后面通常还需接一个名词，如：I don’t know whichone I should buy. I dont know whosebook it is.
变体部分：whatever，however等相当于no matter what，no matterhow，如：I will do _____ makes her happy. 填whatever。

关于我最喜欢的城市的英语作文150字

我最喜欢的城市(my favourite city) Shanghai is my favorite city. I like it because I was born in there, and a lot of my family members and my friends live there. The shopping in Shanghai is cheaper than here, but it’s expensive in China. I have a lot of things to do there, like: shopping, playing, going to my friend’s home… And there’re also a lot of places that are interesting. In Shanghai, people speak the same language as I do. I was there for 13 years! I left there on August, 18th, 2005. And I was there because I was born in there and I lived there. There’re a lot of people in Shanghai. The people are like me. We all speak the same language. The people in Shanghai are busy and friendly. And Shanghai is also and international city. It’s beautiful and fancy. There’re a lot of tall buildings. That’s why Shanghai is my favorite city. It’s my home city. I love Shanghai!!! I’d like to go back to Shanghai, but just for a visit. Although Shanghai is good, I’d like to live here because I’d like to study here. I only get a little homework and the air here is flasher than Shanghai. The weather is hot in Shanghai. And the best time of year to go there is spring, because in spring, the weather is cool and warm. But some people asked me:” Why don’t we go there in the fall? The fall is also cool and warm.” I don’t think so, because in Shanghai, the fall is still very hot. I’d like to recommend this place to other because I want more and more people to know and visit my hometown. I hope if I ask my friends:” Have you ever been to Shanghai? Do you like Shanghai?” The answers shouldn’t be:” No, I haven’t been to Shanghai. And I don’t even know anything about Shanghai!” Now, I’ll recommend you to go to visit Shanghai in summer vacation or winter vacation or spring break or every time you’d like, you’d want, because Shanghai is a very nice city. If you go there, you’ll soon like it!
