一、根据括号中的中文提示或句意，写出句中所缺单词，使句子通顺。
1. Look! The boy is holding his mother's hand tightly while (穿越；横过)the street.
2. She spent a month organizing this (慈善机构)event for the children in need.

1. crossing 2. charity

【分析】
先逐题梳理解题思路：第1题首先观察句子结构，while引导的时间状语部分，主句主语the boy和“穿越”这个动作是主动关系，符合状语从句省略的规则——主从句主语一致且从句含be动词时，可省略主语和be动词，直接用动词的现在分词形式作状语，对应“穿越横过”的动词是cross，变形后即可得到答案。第2题空格后是名词event，需要填入“慈善机构”对应的英文单词，用名词作定语修饰event，构成常用搭配表示慈善活动，符合句意要求。
【解析】
1. 完整句意为：看！这个男孩过马路的时候紧紧攥着妈妈的手。此处是时间状语从句的省略用法，完整结构为while (the boy is) crossing the street，动词cross表示“横过、穿越”，放在省略结构中要变为现在分词形式crossing。
2. 完整句意为：她花了一个月的时间为有需要的儿童组织这场慈善活动。“慈善机构”对应的英文单词是charity，此处用名词单数作定语修饰event，固定搭配charity event表示慈善活动，完全符合语境。
【答案】
1. crossing 2. charity
【知识点】
状语从句省略，现在分词用法，名词作定语
【点评】
本题属于基础的词汇语法结合题型，核心考察常见场景词汇的正确运用，第1题容易误填介词across，要注意区分介词across和动词cross的词性差异，牢记while引导时间状语的省略规则，整体难度不高，适合巩固基础词汇和语法点。

二、根据短文内容，用括号中所给单词的正确形式填空，使短文完整通顺。
Have you ever heard of a famous charity called Operation Smile? Let me tell you something about it.
Operation Smile is an important international children's 1(medicine)charity, working for children around the world born with facial deformities(畸形). It was started by a doctor and his wife.

These volunteers worked very hard. But they 2(worry)that they could not continue with their work, because they were short of money. Then they decided 3(start)a charity so that they could help the children in need. They called it Operation Smile.
Operation Smile mobilizes(组织)a world of kind hearts to heal children's smiles and to make a chance across the globe. The charity manages to work in over twenty 4(develop)countries and 5(help)over 10,000 kids who have problems with their mouths till now. Operation Smile has won many prizes for its work so far. In 1999 they even started a special event 6(call)"The World Journey of Hope". Over 5,000 children in 18 countries are cured during the event.
On the other hand, Operation Smile trains local doctors and nurses in developing countries so that they can continue 7(help)children when Operation Smile has left. As to the children with much 8(serious)problems, they will send them to America for further treatment.

【分析】
做这类词形转换填空题时，首先要先通读整篇短文，把握文章的核心主题和整体的叙事时态，再逐个分析每个空格的前后成分：第一步先判断空格处需要的词性，第二步结合固定搭配、时态语态、比较级等语法规则，把括号内的单词转换为正确形式，最后代入所有答案通读短文，验证语句是否通顺逻辑是否合理。比如看到空格后是名词就优先考虑把给出的名词/动词转换为形容词修饰名词，看到时间标志词就对应匹配正确的时态，看到固定动词搭配就直接套用对应的非谓语形式。
【解析】
1. 空格后是名词charity，需要用形容词修饰名词，medicine的形容词形式为medical，medical charity意为医疗慈善机构。
2. 此处描述1982年发生的往事，整体用一般过去时，worry的过去式为worried。
3. 固定搭配decide to do sth. 表示“决定做某事”，因此填to start。
4. 固定常用表达developing countries意为“发展中国家”，符合语境，因此填developing。
5. 句中出现时间标志till now（到目前为止），需要使用现在完成时，主语The charity是单数第三人称，因此填has helped。
6. 此处event和call是被动关系，表达“被叫做‘世界希望之旅’的特殊活动”，用过去分词called作后置定语修饰event。
7. 固定搭配continue doing sth. 表示“继续做某事”，因此填helping。
8. 空格前的副词much常用来修饰形容词比较级，serious的比较级为more serious，表达“更严重的”。
9. 句意为“我们希望更多人将会加入我们帮助有需要的孩子”，描述未来将要发生的动作，用一般将来时will join。
10. 形容词性物主代词your后面需要接名词，donate的名词形式为donation，此处指代多笔善款，用复数形式donations。
【答案】
1. medical 2. worried 3. to start 4. developing 5. has helped 6. called 7. helping 8. more serious 9. will join 10. donations
【知识点】
词形转换，固定搭配，时态辨析
