有沒有人明白?

Simon is fat用is是因為現時他仍是肥，肥是他的現況，或者他肥是一種事實的講法。如果用Simon was fat意思是他以前是肥，並且暗示他現在不肥了。但全句的內容都是指出所有他是肥的原因，所以全都是事實的講法，沒有顯示想講他現在不肥了，所以文法上一致地用simple present tense。 Family is 是單數。雖然明白你的煩惱是明明陳先生這一個family裏面有很多人，請就用這句中文來理解，「一個」是英文有時不用寫出來的，這是由於英文的字有單眾數詞(中文沒有明確的加s那種寫法，於是要轉用英文詞語寫英文，family本身是單數字便用單數verb動詞，如果講很多個families就用眾數verb動詞。 附註：現代漢語常硬把英文的眾數詞變為加「們」(例如：同學們)，並不是很有效的語文交流，會令中國人和外國人都學錯中文，同時亦會因此譯錯英文。

Family is a collective noun. When a singular verb is used, the group is treated as a unit ~ a “whole" entity. A plural verb presents the noun as a group of people, ~ family members.
