如何讓自己的說話/寫作內容更有變化，第一步就是戒掉but，許多人在使用but時是用錯的，例如在寫作中but是不可以放在字首的，在口說上沒有這麼多的限制，但一直講but but but感覺實在是很枯燥乏味，本篇除了例句之外，也會教導使用方法唷! 要寫作的同學們要注意標點符號的使用喔! 快筆記吧!
1. However 然而
e.g. “Scholar A thinks this. However, Scholar B reached a different conclusion.”
* reach a conclusion 得到結論
e.g. This is one possible solution to the problem. However, there are others.這是問題其中一種可能的解決之道，但還有其他的辦法。
However, he isn’t qualified enough for the job.
This seems to be a fair way; however, we still should carefully consider every aspect.
2. On the other hand 另一方面
e.g. “The historical evidence appears to suggest a clear-cut situation. On the other hand, the archaeological evidence presents a somewhat less straightforward picture of what happened that day.”
文法: On the other hand放句首，後面需要逗號。
3. Having said that儘管如此
e.g. He forgets most things, but having said that, he always remembers my birthday.他很健忘，不過，他一直記得我的生日。
文法: Having said that放句首，後面需要逗號。
4. By contrast/in comparison 相較之下
e.g. “Scholar A’s opinion, then, is based on insufficient evidence. By contrast, Scholar B’s opinion seems more plausible.”
e.g. Their economy has expanded, while ours, by/in contrast, has declined.他們的經濟快速增長，相比之下，我們的經濟則下滑了。
文法: By contrast/in comparison放句首，後面需要逗號。
句中要用: in contrast to
The amount spent on defence is in stark/sharp/noticeable contrast to that spent
on housing and health.國防支出與住房及醫療保健的支出形成了鮮明的對照。
5. Then again 話說回來
e.g. “Writer A asserts that this was the reason for what happened. Then again, it’s possible that he was being paid to say this.”
文法: then again放句首，後面需要逗號。
e.g. He's overweight and bald, (and) yet somehow, he's attractive.他肥胖且禿頭，然而不知為何卻很有魅力。
7.on the contrary 恰恰相反
e.g. "I thought you said the film was exciting?" "On the contrary, I nearly fellasleep half way through it!"「你不覺得這齣電影很精彩嗎？」「正相反，看到一半我差點睡著！」
8. although/though 雖然
e.g. She walked home by herself although she knew that it was dangerous.
Although he is poor, he is happy.
He is happy although he is poor.
9. nevertheless 儘管如此
e.g. Nevertheless, we still believe our new project will succeed.
10. differ from 不同於
e.g. Differ from his position, she claims that this plan still has a lot of flaws.
e.g. Learning a language is not merely about memorizing vocabulary. Instead, it has many aspects to be paid attention to.
*若要放在句子中，可使用instead of 而不是。
*注意 instead後面是接你真正的想表達的東西，而instead of後面接的是你拿來站住立場的反面證據。
e.g. Learning a language has many aspects to be paid attention to instead of memorizing vocabulary.
e.g. We could go to the Indian restaurant, or alternatively, we could try that new Italian place.
13.even though 即使
e.g. Even though he left school at 16, he still managed to become primeminister.儘管他年僅16歲就輟學了，但最終還是當上了首相。
e.g. Despite repeated assurances that the product is safe, many people have stoppedbuying it.儘管已反覆保證了該產品的安全性，很多人還是不再購買。
e.g. Despite his father’s disagreement, he still came to the party.
= He came to the party despite his father’s disagreement.
*若後面要加的為子句(有主詞動詞)，需使用despite the fact that
e.g. Despite the fact that he was born in a very rich family, he still worked really hard to achieve his goal.
15. in spite of儘管
e.g. In spite of his injury, Ricardo will play in Saturday's match.儘管Ricardo有傷在身，星期六的比賽他仍然會出場。
