选A，做伴随状语与主语professor形成主动，故用ing形式。大家都想去游览的是那样好的地方以至于闻名世界。1.__to his research work, the professor cared little about any other things A.Devoting B. Devoted C.Having devoted D.To devote 这样的从句当中,根据主谓一致的原则,前面的从句的主语应该也是the professor.为了使句子简洁,于是省略了主语.完整的句子应该是: the professor devotedto his research work那么这时候,要省略主语用动词开头就只有两种形式-------- -ing/-ed.到底要用哪一个，取决于该动词在完整句子中表示的是主动还是被动，在此句子中，主动用-ing．被动用-ed．这题是主动，所以用 -ing．选择A2.It is such a good place as everyone wants to go and visit that it is well-known all over the world. 这个闻名全世界的地方，是一个人人向往的好地方真正的主语是placeIt is 做的是形式主语和宾语such．．．as：如此．．．．
