1.before是選題的關鍵所在,表明該句應該用完成形式.
2.主句為：Remarkable breakthroughs in gene research may lead to dramatic changes in medical,你可以試著問：具體怎樣做到“l(fā)ead to dramatic changes in medical”呢?方法就是通過“making it possible to create drugs tailored to a patient's genetic makeup”
E項句子都讀不通；
D項偉定語從句,這里不適用.
3.celebrate sth with 用.方式慶祝.1.我上過新東方的課，那老師說after/before/until引導的時間狀語從句不搭配現在完成時，而是搭配過去完成時和一般過去時。這里的D選項卻用了having been?2. make的用法不是make (sth) do或make it to sth嗎？而C選項是make it to do?幫忙解答，謝謝！1.在此提一點建議，新東方老師講的多是應試技巧，對于老師講的東西，你最好能夠分析真正理解，找到其根本所在，使之成為你自己的東西，做到不變應萬變（題型一直在變），否則。。。2.此處“Never having seen anything like this style of architecture before”是一個原因狀語從句，此處省略了主謂語“I had not seen nything like this style of architecture before ”,因為后面還有一套主謂語，一個句子中不能出現兩套主謂語，于是我們通常會將其中一套主謂語用狀語的形式給出。此處還有一種類似情況：seeing the house on fire,I called the police immediately yesterday.3.請不要斷章取義，原句為“making it possible to create”分解如下：make it be possible;it is possible to do sth.
