23、修饰movies，这是一个谓语部分为系表结构的句子。解析：make up 意思是“组成，构成”。“A make up B ”（A构成了B），它可以转换成“B is made up of A ”（B 由A 构成）。如：Twelve players make up a basketball team.12名运动员组成一个篮球队。A basketball team is made up of twelve players.一个篮球队由12名运动员组成。make up 还可以表示“编造，虚构；化妆；补充，弥补”等。Jake is good at telling and making up jokes.

25、on and this growth is clearly going to continue.1983年，只有200台计算机联网，如今大约有5千万台计算机联网，而且很显然这种增长将持续下去。connected to the internet 是一个过去分词短语作定语，修饰computers,相当于定语从句which were connected to the internet,在第二个分句中，million 之后承接上一句，省略了computers.million of 或a million of 是表示大概的数目，类似用法的词还有score（二十），hundred, thousand, b

26、illion等。与不具体的数字连用时，不用复数，且后面不接介词of.如：During the holiday, tens of hundreds of people enjoy themselves on Quancheng square.假日期间，许多人在泉城广场休闲。Three hundred students attended the meeting yesterday.300名学生出席了昨天的会议。2. In the future, terrorists may “attack” the worlds computers, cause chaos, and make planes an

27、d trains crash.将来，恐怖分子会袭击世界上的电脑，引发混乱，使飞机坠毁，火车相撞。解析：这是一个简单句，主语是terrorists, may attack, cause 和make 是三个并列的谓语。crash 作宾语planes and trains 的补足语，在make （使）之后作宾语补足语的不定式要省去to。记忆要诀 巧记后接省去to 的动词不定式作宾语或宾语补足语的词（组）：为什么不听不看（why not, listen to, hear, look at, see, watch, observe, notice）；宁愿请，最好让（would rather, would

28、 you please, had better, let; have, make 表使唤；feel表示触摸感。）3. She also believes that, in the future, we will get entertainment from the Net and that television will probably disappear. 她还相信将来我们会在网上娱乐，电视也许会消失。解析：谓语动词believes 之后接了两个宾语从句，宾语从句用and 连接。反意疑问句中，如果陈述部分是“I （we）（dont）think （believe, suppose, imag

29、ine）+宾语从句”时，疑问部分中的主语应与宾语从句中的主语保持一致，如果是否定句，否定意义还是要转移到宾语从句。如：I dont think he is forty, is he ? 4. Some experts see our future in virtual reality the use of computers with sounds and pictures that make you feel as if you are in a real situation.一些专家在虚拟现实里看到了我们的未来，使用带声像的计算机使你觉得你是在真实的情景中。that make you fe

30、el as if you are in a real situation 是一个定语从句，修饰sounds and pictures,其中as if you are in a real situation 是状语从句，修饰和说明动词feel。5. I see people living and working in a virtual world.我看见人们在虚拟世界生活和工作。living 和working in a virtual world 是现在分词短语作宾语people 的补足语。现在分词和不定式在作宾语补足语的意义上有些不同，不定式指事情的全过程，目的在于仅仅说明了这件事；现在分词

31、指正在进行的动作的一部分，目的在于将该动作当时进行的情景呈现于读者眼前，相当于进行时态。 I saw him go upstairs.我看见他上楼去了（强调上楼的全过程）。I saw him going upstairs.我看见他正往楼上去（强调上楼动作的进行）。【典型例题】综合阅读A school bus is a bus to take you from your house to school and back again.Its also a place to meet kids from other place, and a place to finish yesterdays homework if you forget to do it and finish todays homework before you get back home although homework done on the bus never gets good grades, no matter how hard you try.There are three things I dont li
