7.答案：
D
解析：考查介词/介词短语；be
good
for
sth是对某事有好处，介词用for；agree
with
sb是同意某人的观点/看法，介词用with。据此分析，A介词使用不对；B介词使用不对；C介词使用不对，D介词使用正确。故D项符合
。
8.答案：
B
解析：考查实义动词；根据句意：她通常游泳。A游泳，动词原形；B游泳，动词第三人称单数形式；C正在游泳，现在进行时；D不定式。由于主语是第三人称单数形式，此句又属于一般现在时，故B项符合。
二、句型转换

in
good
health身体健康=be
healthy，故答案为is
healthy。
点评：考查句型转换。理解句意，掌握英语句子的不同表达方式。
10.答案：Maybe
解析：句意：他爸爸也许在家睡觉。may
be是情态动词+动词原形结构，是句子的谓语部分；maybe副词，在句中作状语，故答案为Maybe。
点评：考查句型转换。理解句意，弄清句子结构，掌握句子的不同表达方式。
11.答案：How；often；does；eat
解析：句意：汤姆一个星期吃一次饺子。once
a
week表示频率，所以用how
often提问；注意助动词does提前，故答案为How
often
does；eat。
