解析
【分析】
本题为英语课文还原填空题，需结合语境、语法规则、固定搭配及词性转换确定每个空的答案。解题思路：先分析空格前后的词性、逻辑关系，再结合固定搭配、时态、词性变化规则推导答案。
【解析】
1. 空格后为可数名词单数artificial arm，表泛指且artificial以元音音素开头，故填不定冠词an；
2. 语境为女孩天生没有手臂，be born without是固定搭配，表“天生没有”，故填without；
3. 前半句说手臂是简单的钩子，后半句说价格昂贵，前后为转折关系，故填连词but；
4. what's worse是固定短语，表“更糟的是”，需用bad的比较级worse，故填worse；
5. 表示“第十六个生日”，需用序数词，故填sixteenth；
6. 全文为一般过去时，谓语动词用过去式，weigh的过去式为weighed，故填weighed；
7. keep doing sth是固定搭配，表“坚持做某事”，故填work的动名词形式working；
8. 全文为一般过去时，cost的过去式与原形一致，故填cost；
9. 空格处需名词作主语，invent的名词形式为invention，故填invention；
10. 空格处需形容词修饰名词hand，help的形容词形式为helping，构成固定短语helping hand（援手），故填helping；
【答案】
an, without, but, worse, sixteenth, weighed, working, cost, invention, helping
【知识点】
不定冠词用法；介词搭配；动词时态；词性转换；固定短语
【点评】
本题侧重考查英语基础语法与词汇的运用，结合语境和固定搭配即可解答，是初中英语常见的基础题型。
【难度系数】
0.6
