I have come to realize后加宾语从句 what selfless love is all about ,about 是介词，后加宾语what。如问句：What is selfless love all about? 无私的爱是什么?人不是太阳月亮，很多属性可能变了，甚至都不在了。以前是澳大利亚人，现在可能是美国人了，以前是老师，现在可能是老板了。otherwise 在这里是 in a different way 以另外方式。如He is rich, but otherwise an unhappy man.他有钱，但在其他方面是个不幸福的人。改成therefore是与上文逻辑一致。I hope my advice will be some help to you 应该在be后加of: I hope my advice will be of some help to you. be of some help意思是be helpful。agree to 和 agree with搭配上：agree to a plan, scheme, or project agree with somebody或sth agrees with sth. “与...一致”如 That story does not agree with the facts.意思上：agree to 有一方勉强同意...的意思，而 agree with是 “与...一致”当序数词在句中作状语时，序数词前不用theWho got there second? 谁第二个到那儿的？I finished the work first. 我最先完成那项工作。或者说，当表达考试（赛跑等）中获得的名次时，序数词前不用She stands first in his class. 她在班上成绩排名第一。希望对你有帮助。
