    We _______ work very quickly.

    A．don’t needB．needn’t toC．need not toD．don’t need to

    D

    解析试题分析: 此题重点考查动词need的用法，它有两个词性，作为情态动词时经常用在否定句中，并且后跟动词原形；作为实义动词时后可跟名词，动词不定式，动词的现在分词（表示被动意义）,其否定形式要借助助动词do的形式.根据语境可知此句的含义是我们没有必要干的那么快.根据语境和need的基本用法,可知D为正确答案.
    考点：need的基本用法。
    点评：此题的关键要看怎样区分need的词性.A和D中的need是行为动词,但作为行为动词need的基本用法是need to do sth,A的答案是不对的;B和C都是情态动词,而need作为情态动词其后只能跟动词原形,故其也是错误的,故选D.因此区分need的词性是解题的关键,但要分析题干的基本结构.

    Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
    Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
    "We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
    British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
    But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It's hard to get a clear result.
    Will there be a better indicator than litmus paper? The three kids decided to try and find out!
    How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
    The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
    "It's our first scientific journey, Huang said, "But it makes me want to try harder."
    【小题1】 Whom did the three kids want to challenge?
    A．Their chemistry teacher.B．Their headmaster.
    C．Robert BoyleD．Thomas Edison
    【小题2】 From the text, a red cabbage is a kind of ____.
    A．plantB．animalC．paperD．liquid
    【小题3】What is widely used as the acid-base indicator now?
