选择题：Since she is angry, we . A. had better to leave her alon

你的问题应该是这样的吧?Since she is angry,we ______。a。had better leaving her alone b。should leave her alonec。might as well leave her alone d。had rather leave her alone答案：可以用排除法,我的分析是这样的A：因为had better的用法是 had better+do 后不应该用现在分词,应该是had better leave her alone就对了B：意义不对,这里使用should的话表示了应该去做没有做过的事情比如：You should complete your test in time。你们应该及时完成你们的测试。（但实际没有完成）。可以看到,用进去意义就不对了。C：might as well 还可用于指过去的情况或用于比较两个令人不愉快的情况,强调前后主语要一直另外是不愉快的情况。所以不对。D：had rather表示宁可,宁愿 比如：I had rather join you in research work than go on holiday to the seaside。我宁愿和你们一起参加科研工作,而不愿去海滨度假。所以原句的解释应该是因为她生气了,所以我们宁可让她一个人待着
