一、 1。 spend+时间或金钱+in doing sth。(in可以省略)。 eatchangesrevolution我猜可能是大跃进吧,那是1958年的事,所以是已经发生的事,用过去完成时 3。如果要用other two的话，前面得加the二、这里要根据语义，不论是以总统还是普通游客的身份，我们都欢迎尼克松访华。所以用either …or ，要么以而总统身份正式外交，要么以朋友身份参观游览，而both …and是双重身份，矛盾了。三。may be 表示推测，前后语态一致 不用might四。 ay是不是得加as 但这些词都得加s吧 cause,since,as为从属连词，for为并列连词 因为前面有“，”号，所以用for。since as一般放在句首用。五、extremely表示程度“极其、非常”, greatly 只修饰动词及分词，例greatly appreciated六。region常指较大的行政单位，有一定界限的地区，还可用来指人体的某个部位 Area通常指面积可测量或计算的地区，但不是行政上的地理单位 range指“运用心、眼、机器、力量等所能概括的整个范围”,为抽象名词 这里指的是实际面积 land一般指土地你的问题真多，费了好大劲！！：）。

1.固定搭配spend some time doing sth. 花费一定时间做某事
