3F是錯的，Even不可當連接詞。接下來看 Even if 和 Even though 哪一個可以？ Compare the following: Even if I had two hours to spare for shopping, I wouldn't go out and buy a suit. Even though I had two hours to spare for shopping, I couldn't find the suit I wanted. The first example describes an unreal situation where we could substitute 'just supposing' for even if and say: just supposing I had two hours to spare for shopping, I still wouldn't go out and buy a suit. Note:that even cannot be used as a conjunction like even if and even though when it stands alone. We cannot say: Even I've polished and cleaned it, it still doesn't look new. Even can also go at the beginning of a phrase when it refers to words or expressions that we wish to emphasize, again because this is surprising information for the listener: He works all through the year. Even at Christmas and New Year! I know his English isn't very good but even I can understand him!
