2023-2024学年第二学期甘肃省永昌县赵定庄中学联片教研九年级英语第三次模拟考试试卷一、单项选择题(共25分)1. —Will daddy drive me to school today, mummy?—Didn’t you find the two ________ bottles of beer on the table? I will, instead.A. cleanB. silentC. deadD. absent【答案】C【解析】【详解】句意：——妈妈，爸爸今天会开车送我去学校吗？——你没有看到桌子上那两个空啤酒瓶了吗？我来送吧。

考查形容词辨析。

clean干净的；silent沉默的；dead用完了的；absent缺席的。

根据“I will, instead.”可知，妈妈来送孩子上学，结合“two...bottles of beer”可推测，爸爸不能送孩子上学是因为他喝完了两瓶啤酒，醉了，dead符合语境。

故选C。

2. The teacher made us English exercises all the time.A. didB. doC. doingD. to do【答案】B【解析】【详解】句意：老师让我们一直做英语练习。

make sb do sth使某人做某事，故选B3. The young man ________ eats at home, because he isn’t good at cooking.A. alwaysB. usuallyC. oftenD. seldom【答案】D【解析】【详解】句意：这个年轻人很少在家吃饭，因为他不擅长做饭。

考查频率副词。

always总是；usually通常；often经常；seldom很少。

根据“because he isn’t good at cooking”可知，因为不擅长做饭所以很少在家吃饭，故选D。

4. We’re not very close friends________ we’ve known each other for a long time.A. untilB. althoughC. asD. if【答案】B【解析】【详解】句意：虽然我们认识很长时间了，但我们不是很亲密的朋友。
