SC新題考點分布及例題分析
同學們都知道，OG21的新題目出來了，SC部分一共新出了31題，里面涉及到最多的考點還是平行和比較考點，今天老師帶同學們看其中3題相對復雜的題目。
1. Satellite radio transmissions, a popular feature in car stereos, differ from those of AM and FM radio, which is sent directly from earthbound towers and then to a car stereo.
A. which is sent directly from earthbound towers and then to a car
B. which are sent directly from earthbound towers to a car's
C. sent from earthbound towers and then directly to a car
D. sending them directly from earthbound towers to a car's
E. being sent directly from earthbound towers to a car
考點：平行 修飾
解析：
A選項：根據(jù)定從的is，修飾AM and FM radio，單復數(shù)不一致。
B選項：根據(jù)定從的are ，which定從修飾AM and FM radio，正確。
C選項：from...to...中間的and then 冗余
D選項：，sending from...現(xiàn)在分詞短語做狀語修飾謂語動詞differ，其邏輯主語，也就是主句主語Satellite radio transmissions不能主動的發(fā)出這個動作。
E選項：錯同C，且being冗余。
關(guān)于CD選項，要提醒同學們分詞結(jié)構(gòu)做定語修飾名詞，做狀語修飾動詞，逗號+現(xiàn)在分詞短語，只可以做狀語，而過去分詞沒有這個限制。
2. Just like the Internet today, often being called an “information superhighway,” the telegraph was described in its day as an “instantaneous highway of thought.”
A. Just like the Internet today, often being
B. Just as the Internet is today often
C. As with the Internet being today often
D. As is often the case today with the internet,
E. Similar to the Internet today, often
考點：比較
解析：
AC選項：being冗余。
B選項：正確，兩種情況的比較。
D選項：As is often the case today with語義不合理，講的是was described in its day as an “instantaneous highway of thought.”同一種情況適用于兩者the Internet和the telegraph。例：As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful on-line drugstore
E選項：錯同D
3. As opposed to adults, pound for pound, children breathe twice as much air, drink two and a half times as much water, eat three to four times as much food, and have more skin surface area.
A. As opposed to adults, pound for pound, children
B. Compared pound for pound with adults, children
C. Unlike an adult, pound for pound, children
D. Pound for pound, a child, unlike an adult, will
E. Pound for pound, children compared to adults will
考點：比較
解析：
A選項：as opposed to 是（表對比），與...相對，而不是的語義，而根據(jù)后面的語義，twice as much，這里需要的是比較的含義，而不單單是對比，就比如：我有玫瑰花，而她有茉莉花。
B選項：正確。
C選項：pound for pound，修飾的應(yīng)該是比較的程度，這里變成插入語，有補充說明adult的歧義。
DE選項：will時態(tài)錯誤。
