2. 可以變換壹下句式顯得沒那麽啰嗦，比如說”want to be succeed"/'want to be successful'可以交替使用。
3. “But all the opportunities are accompanied with challenges though not all the challenge will make you succeed.”很簡單的語法問題，but和though不能出現在同壹句子裏；
·妳在闡述壹個道理，opportunites和challenges都應該不用the去特指；
·而將句子改為”Not all challenges will make you successful, but all opportunities are accompanied with challenges"，避免了原句的頭重腳輕。
4. "So I think success is not only need diligence,but also need a little luck." 改為“So I think success needs only diligence,but also a little luck.” （語法問題）
5. “Edison ever said”改為“Edison had said”（語法錯誤）
6. "it need you lucky enough to meet it." 改為 “ it needs you to be lucky enough to meet it.”（語法錯誤）
7. “And can you have the ability to pass the challenge?” 改為 “And do you have the ability to get through the challenge?”（表達不當）
8. "She was the first woman to win two Nobel prizes." 改為 “She was the first woman who win two Nobel prizes.”（語法錯誤）
9."But she wasn't content."改為“But she was not content.”並把“not”重讀使得句子強調更重。
10.“There are many challenge and only one opportunity at Madame Curie's life.” 改為 ”There are many challenges but only one opportunity in Madame Curie's life.“ 。我發現文章有很多關於單復數的錯誤，重復的我就不壹壹指出了；
·將”and“改為”but“體現轉折的語氣
·”in one's life“ 短語
11. "She was looked down upon because she was a woman." 改為 ”She was looked down upon by others because she is a woman.“ 加壹個”by others“使得句子更順；如果說的是事實，就不用過去式，直接”she is a woman“，如果說”she was a woman“就好像她以前是女人，然後做變性手術變成男人了……
12. All of her experiment was dangerous……” 改為 “All of her experiments were(這裏用are應該也可以） dangerous……” 同樣是單復數問題。
13."her husband was dead of a accident" 改為“her husband died in an accident”，註意是“an accident”
14.”But she had never given up and passed all the opportunity“.改為“But she had never given up and grab all the opportunities.”
15.“gather experience” 改為“gain experience”
16."pass the challenge" 改為“get through the challenge”
17.“That is all my speech, thank you.” 改為“ that's all for my speech. thanks for listening.”
妳也可以在百度搜“英語演講結束語”，選個妳喜歡的吧。
不知道妳是幾年級，不過這篇演講真的是太多錯誤了。如果是演講比賽之類的話，我勸妳舉的例子不要有太多的生僻詞匯，到時忘了怎樣讀了更麻煩，而且我相信那些單詞老師也未必聽得懂。什麽是演講？我覺得好的演講是能帶動聽眾的，我是大學生，參加過兩次演講比賽，這都是經驗之談，希望的采納為最佳答案！謝謝！
