题目内容
15.It is reported that many middle school students are just not getting enough sleep,especially during the school week.The problem seems to get(41)worse(bad) as they get older.Year 7 students sleep 8.4 hours in a school night,and Year 9 students only 6.9 hours.分析 很多孩子睡眠不足,而且随着年龄增大问题看起来更严重.他们会在课堂上睡着了,所以他们比那些睡眠充足的孩子得分低是不令人吃惊的.为什么存在这个问题呢?主要是电视,电脑,电话的问题.在学习的时间的夜晚玩手机不仅会占用写作业的时间,而且使他们很难入睡,但是第二天他们还需要早起去上学.所以科学家建议孩子在睡前一小时不要坐兴奋的事.
解答 41.worse.考查比较级.根据as they get older可知随着年龄增大问题看起来更严重.所以用bad的比较级worse.
42.problems.考查名词.problem是可数名词,本句里problem前面没有表示数量的词,而且问题肯定不是一个,所以用复数.problems.
43.asleep.考查派生词.固定短语fall asleep表示入睡,asleep是形容词.
44.surprising.考查派生词.根据上文可知that they get lower grades than those who get enough sleep(他们会比那些睡眠充足的孩子得分低)是不令人吃惊的,所以用surprising,表示"令人吃惊的".
45.unhappy.考查派生词.和nervous并列,表示负面情绪用unhappy.表示"不高兴".
46.following.考查派生词.following是形容词,修饰名词things表示"下面的事".
47.Using.考查非谓语动词.Use them on a school night 在句子里做主语,所以用doing..表示"在学习的时间的夜晚玩手机不仅会占用写作业的时间,而且使他们很难入睡."
48.it.考查代词.根据makes和difficult for them to sleep可知用it做形式宾语,代指to sleep,表示"使他们很难入睡".
49.to go.考查非谓语动词.做get up early的目的状语用动词不定式to go,表示"早起去上学".
50.before.考查前后的逻辑关系.根据常识可知应该在睡前避免做令人兴奋的事,所以用.before.
点评 考查语法填空.
it可以做形式主语和宾语.
1.it用作形式主语
当不定式、动名词、从句等用作主语时,为避免头重脚轻,通常在句首使用形式主语it,而把真正的主语放在句子末尾.如:It's a pity to refuse.拒绝是令人遗憾的.
2.it用作形式宾语
当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时,就应在宾语补足语前使用形式宾语,而将真正的宾语移至句末.如:I find it easy to get on with her.我发现她很容易相处.
