Lavf58.29.100 Packed by Bilibili XCoder v2.0.2 $这探索宇宙的奥秘。我的梦想是如此伟大，但他们却阻止了我前进的脚步。Time to be . red is not as perfect as you thought. I want to look like the red, but I cannot. The dream wants me to look like the red the most, have a strong body to protect the yellow. My only hope is to have a quiet environment. Ment. 咦，为什么我说的话跟他们的那么像？你们仔细看看，能不能找出我们说话的共同之处？啊哈如果你能发现每句话都有吐吐，那此处应该有掌声。To加动词原形构成to do形式，并取了个名字叫动词不定式。为什么它叫不定式呢？因为它在句子里的位置是不固定的，可以做主语、宾语、表语、宾补、定语和状语。嘿嘿，以我们刚才的话为例，来看看动词不定式是否真的这么神通广大。To be red is not as perfect as . you thought. 这里的土鳖是不定式做了主语OK下一句。i want to look like a red, but I cannot. 这里的不定式。to look like跟在动词want的后面，当然做的就是宾语。Will the next one? The Green wants me to look like the red. 这里的to look like跟在宾语me的后面是补充说明密的，所以做的是宾语补足语。再看看小绿说的。i have a strong body to protect the yellow, 这里的to . protect是在状语的位置上，所以做的就是状语了。You see, 我是酱子说的，my only . hope is to have required environment. 那这里的不定式to have做的是什么成分呢？啊哈他跟在了系动词意思的后面，答案就是做表语喽，不定是够牛。除了卫浴，他啥成分都能做OK现在该看看你的审美水平了。Which one is Better? A to have one's own factory is really exciting. B IT is really exciting to have our own factory. Yes, 第二句更好，因为第一句有点头重脚轻的赶脚。那第二句的IT是从哪冒出来的呢？因为一个有个奇特的功能，就是做句子的形式主语，专门用来对付头重脚轻的问题。其实它只是一个形式上的主语而已，它的真正内容是后面的图图不定式。To have one in factory. 怎么样？你明白了吧？那还不快来练练手，三分钟内跑1000米真的很困难。答案就是IT is really . difficult to run one thousand meters in three minutes。哈哈。所以你可以这样子说，一头与土豆是形式与内容的关系。讲了这么多，你是不是要大显身手了？Lets go. 什么is difficult to get like the figures，a this b that see IT b it's. So easy, 很明显这里缺的是主语，根据刚才讲过的IT可以做形式主语，很容易判断，这里应该选c IT OK。让我们再来一例。I tell them in a factory, a don't talk. B talk nut. C to not talk do not at all. OK答案是4D你做对了吗？如果你选错了，也不要伤心，我是逗你玩的。这里涉及到了我们还没讲的不定式变否定。不定式变否定是在to do前面加note构成not to do的形式。所以刚才的题目应该选not to talk OK the last one. we decide duty at the end of this month. A travel, b not start out. C to leave. D going. 正确答案是C因为动词decide后面必须加to do。英语中常加to do。做宾语的动词主要有what？Decide, ask, agree, choose, learn, plan, prepare. 哈哈你记住了没有？现在我要去实现我的伟大理想了。To be a great captain, 拜拜。
