mustⅢ.语法填空
Are you any good at hula-hooping (转呼啦圈)? If 1.____________， don't worry. It's so easy to learn that you can understand its working principle 2.__________ any hula-hooping experience. 3.____________ (be) you interested, you could examine some interesting knowledge of physics behind hula-hooping using just a pencil and a rubber band.
Hula hoops' move 4.____________ (determine) all by forces! While playing with a hula hoop, many different forces are at work to help keep it 5.__________ (circle). A force is a push or a pull that acts on one thing. Forces can make objects move, but just that something isn't moving doesn't 6.____________ (necessary) mean there're no forces acting. For example, if you're sitting on a chair right now, there is an upward force on you 7.____________ prevents you from falling to the ground. On the contrary, when something is moving, we can't say it gets 8.__________ (evidence) force acting on it.
So what forces act on a hula hoop? 9.____________ (weigh), friction, the normal force, etc. Just as you can see, the 10.____________ (combine) effect of all these makes it spin.
[语篇解读] 这是一篇说明文，主要由呼啦圈的工作原理引入主题，介绍了力的作用。 1．解析：考查省略结构。上文问“你擅长转呼啦圈吗”，此处答“如果……，不要担心”，根据逻辑关系可知，此处应该表示如果不擅长，故用if not“若非如此”。 答案：not
2．解析：考查介词。结合“don't worry. It's so easy to learn...experience”可知，该句话意为没有任何玩呼啦圈的经验也能明白其工作原理。空后是名词短语，所以用without “没有，缺乏”。 答案：without
3．解析：考查虚拟语气、省略和倒装。分析句子结构可知，本句是虚拟条件句，表示与现在事实相反的假设，从句用一般过去时(be动词用were)，主句用could/should/might/would do。从句省略了if，将were提前构成倒装，故填Were。注意句首单词的首字母要大写。
- 2 -
答案：Were
4．解析：考查时态和语态。此处在讲一个原理，用一般现在时表示陈述事实。又因Hula hoops' move与determine之间是动宾关系，所以用一般现在时的被动语态。 答案：is determined
5．解析：考查非谓语动词。此处是keep sb./sth. doing结构，表示“让某人/某物保持做某事”，故用现在分词作宾补。 答案：circling
6．解析：考查词性转换。空处修饰动词mean，故用所给词的副词形式necessarily。 答案：necessarily
7．解析：考查定语从句。分析句子结构可知，空处引导一个分隔式定语从句，修饰前面的先行词force，并在从句中作主语，又因先行词为物，所以用that或者which。 答案：that/which
8．解析：考查词性转换。空处位于名词force前作定语，应该用形容词evident “明显的”。 答案：evident
9．解析：考查词性转换。空处与后面的名词friction和名词短语the normal force并列，故用所给词的名词形式。注意此处首字母要大写。 答案：Weight
10．解析：考查非谓语动词。此处为非谓语动词作定语，effect和combine有着逻辑上的动宾关系，故用过去分词。 答案：combined Ⅳ.短文改错
