4小题怎么做谢谢？

Answer 1

【答案】【小题1】Why do you usually do to keep healthy?【小题2】Thank you for giving us some candy/candies/sweets as a treat.或Thanks for treating us with some candy/candies/sweets【小题3】He spends half an hour (in) reading newspapers every day.或 It takes him half an hour to read newspapers every day.【小题4】In her free time, Sandy learns/ studies English and enjoys music.【小题5】Children of ten help their grandparents (to) get ready for supper.【答案解析】试题分析：【小题1】考察短语keep healthy，保持健康。【小题2】考察句式Thank you for doing sth或者Thanks for doing sth谢谢你做某事。注意介词for后面接动名词作宾语。【小题3】考察“花费”的英语表达。take 用于 it takes sb ... to do sth句型，仅指花费时间（three hours等），必须用it作形式主语；spend用于sb spend...on sth或者sb spend...in doing sth（in可以省略），spend的主语必须是人，可以指花费时间、也可以指花费金钱。【小题4】考察一般现在时态。注意主语桑迪是单数第三人称，谓语动词用单数形式。Study加s规则指去掉y变i，再加es。【小题5】考察help用法及短语get ready for为……做准备。注意help后不定式符号to可省略。考点：汉译英点评：在做汉译英时，首先应该根据句子的时间状语，逻辑关系确定句子的时态；其次，根据相关信息确定主要句式短语；第三，注意句子中人称、数以及时态问题。第四、注意英语的表达习惯及常见搭配等问题。

Answer 2

正方形的边长＝√（6×6+6×6）=6√2
S阴影＝6^2兀-6√2×6√2
=36兀-72

Answer 3

你好
阴影面积=圆面积-正方形面积
圆面积 : 6x6x3.14
=113.04cm²
正方形面积（两个直角三角形面积之和） :
底6x2=12cm
高6cm
12x6÷2x2=72cm²
阴影面积 : 113.04-72
=41.04cm²
阴影面积41.04cm²

Answer 4

阴影面积
6x6x3.14-6x6x2
=113.04-72
