請問一下~ Q1:Since June,Jake___rather than driving to the fitness center.He has more time now that he is retired. a.walking b.has walked c.is walking d.has been walking A:d 請問為什麼不是B而是D呢?因為since不是都接現在完成式比較多嗎?? Q2:He__take a taxi to the airport,but it makes more sense for me to just drop him off. a.should b.ought to c.could d.will A:B 請問為什麼答案是b而不是a 到底should跟ought to 該怎麼分辨呢?? 謝謝老師的幫忙瞜~

the best way is to look at the word driving. it is verb+ing. so the first verb also needs to be verb+ing Jake has been walking instead of/rather than driving Walk and drive must be in the same tense. Jake has been walking and Jake has been driving (Perfect continuous) Then you simplify it to just Jake has been walking and driving In this case, it’s rather than, so, Jake has been walking rather than driving. You can have has walked too but you’ll have to change driving into drived Jake has walked and Jake has drived (perfect) Jake has walked rather than drived. After since, we need a perfect tense (either present perfect or present perfect continuous) but both verbs must be in the same tense!!

Q1:Since June,Jake___rather than driving to the fitness center. He has more time now that he is retired. a.walking b.has walked c.is walking d.has been walking A:d 請問為什麼不是B而是D呢?因為since不是都接現在完成式比較多嗎?? 這裡用現在完成進行式才能表示將來還會繼續下去。因為從後面看到他已經退休，以後會有較多的時間，在邏輯上，這是表示從此以後都是如此了，有繼續進行下去的意思。此外用了walking可以和driving 對稱。因為遇到rather than來做比較，這也是應該的寫法。 Q2:He__take a taxi to the airport,but it makes more sense for me to just drop him off. a.should b.ought to c.could d.will A:B 請問為什麼答案是b而不是a 到底should跟ought to 該怎麼分辨呢?? 用should時表示這是我的想法（I think he should take a taxi），但後面又有it makes more sense for me來表示我的想法，同一句話中我有兩個相反的想法，是不對的。所以前面不能用should。該用ought to，這和我的想法不衝突，ought to=must只是單純的敘述，表示他受別人（或別的事情）的影響，必須去做，和我的意見無關。所以不衝突。這題只能選B。
