汉译英
1._______(很明显)that Jack has returned.
2._________(几乎所有行为都是学来的)is a basic assumption of social scientists.
选做★:His ability has never been in doubt,but the question is________(他是否已准备好努力工作。)
1.It is evident
【解析】该题考点为主语从句后置,句首it充当形式主语
2.That nearly all behavior is learned behavior
【解析】该题考察主语从句的用法。主语从句需有连接词that引导,且不能省略(引导宾语从句的that可以省略)
选做★:whether he is prepared to work hard
【解析】该题考察表语从句的使用,前文中表示never in doubt,即为肯定之意,而后文中用but转折,表示与前文不一样的感情色彩,即有些怀疑,所以应用表示不确定的引导词whether或if;由于if不能用在表语从句中,故只有使用whether.
