Answer 1

1、选A。prevent sb. from doing sth.，是固定短语用法喽，表示阻止某人做某事。整句的意思是：我昨晚筋疲力尽了，但为胃中剧痛所阻而不能入睡。这里当然是我被阻止啦，所以用被动。
2、选B。what is known to us all作为主语哦，表示众所周知的意思啦。整句意思：众所周知（的是）2016年奥运会将会在里约热内卢举行。这里主要分析清楚句子的结构，is （that+后面的一大串）也就是谓语与宾语喽。
3、选B。floating，漂浮着的。floating in the pool作为状语补充形容模型船的。整句意思：看见池中漂浮的船模了没？那是我爸上周末做给我的。
还有不懂，再问我哦。求分！
