C 解析：enough修饰形容词large要放在后面，large enough表示“足够大” 3. B 解析：句意为“他太累了，不能继续走了”，考查“too...to...”结构（太……而不能……） 4. B 解析：enough修饰名词money要放在前面，enough money“足够的钱” 5. C 解析：根据后句“每个人都能回答”可知问题“足够容易”，easy enough放在系动词后 6. A 解析：根据后句“我们不能喝”，可知水“太”烫了，用too修饰hot 7. B 解析：句意为“恐怕现在太晚了，不能出去了”，考查“too...to...”结构 8. A 解析：根据句意“这个男孩太小了，不能照顾自己”，表示“太……而不能”用too...to... 9. D 解析：修饰动词speak用副词loudly；enough修饰副词要放在后面，故用loudly enough 10. B 解析：修饰动词ran用副词fast；enough修饰副词要放在后面，fast enough表示“足够快” 11. A 解析：根据后句“它们不合脚”可知鞋“太小”了，用too small 12. D 解析：根据后句“我们不必着急”，可知“有足够的时间” enough修饰名词time放在前面 A太多（修饰不可数名词），B太（修饰形容词/副词），C很多，但不如enough直接对应 13. C 解析：句中有名词girl，用such...that...结构，表示“如此……以至于……” 14. A 解析：句意为“这道题太难了我解不出来”，考查“too...to...”结构 15. B 解析：根据后句“他有足够的钱”，可知他“足够有钱”，rich enough放在be动词后 16. B 解析：根据后句“不凉”，可知汤“足够热”，hot enough 17. D 解析：句意为“你应该先做作业” be supposed to do sth.“应该做某事”，是固定短语 18. B 解析：句中boring是形容词，用“so + 形容词 + that从句”结构，表示“如此……以至于……” 19. B 解析：句中young是形容词，且后接从句，用“so...that...”结构 A项too...to...后要接动词原形，不能接句子 20. A 解析：句意为“这个男孩够大了可以去上学”，old enough放在be动词后 （二）句型转换 1. too; to 解析：将“so...that...”否定句转换为“too...to...”结构 2. too; to 解析：原句“old enough to”（足够大能）的反义表达是“too young to”（太小而不能） 3. not light enough 解析：原句“too heavy to move”（太重搬不动）= “not light enough to move”（不够轻所以搬不动） 4. too; to 解析：原句“没有足够的钱买房子” = “太穷了买不起房子”，用too poor to buy 5. easy enough; to 解析：合并为“easy enough for everyone to answer”（足够容易每个人都能回答） 6. not tall enough 解析：原句“too short to reach”（太矮够不到）= “not tall enough to reach”（不够高所以够不到） 7. fast enough to 解析：原句“ran so fast that he could catch”（跑得如此快以至于能抓到）= “ran fast enough to catch”（跑得足够快能抓到） 8. too; for anybody to 解析：原句“such a heavy box that nobody can move”（如此重的箱子没人能搬动）= “The box is too heavy for anybody to move”（箱子太重谁都搬不动） 9. old enough to 解析：原句“too young to go”（太小不能去）= “not old enough to go”（不够大所以不能去） 10. doesn’t have 解析：主语he是第三人称单数，变否定句要借助doesn't，后面动词用原形have 1 学科网（北京）股份有限公司 $
