SC新题考点分布及例题分析
同学们都知道，OG21的新题目出来了，SC部分一共新出了31题，里面涉及到最多的考点还是平行和比较考点，今天老师带同学们看其中3题相对复杂的题目。
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
考点：平行 修饰
解析：
A选项：根据定从的is，修饰AM and FM radio，单复数不一致。
B选项：根据定从的are ，which定从修饰AM and FM radio，正确。
C选项：from...to...中间的and then 冗余
D选项：，sending from...现在分词短语做状语修饰谓语动词differ，其逻辑主语，也就是主句主语Satellite radio transmissions不能主动的发出这个动作。
E选项：错同C，且being冗余。
关于CD选项，要提醒同学们分词结构做定语修饰名词，做状语修饰动词，逗号+现在分词短语，只可以做状语，而过去分词没有这个限制。
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
考点：比较
解析：
AC选项：being冗余。
B选项：正确，两种情况的比较。
D选项：As is often the case today with语义不合理，讲的是was described in its day as an “instantaneous highway of thought.”同一种情况适用于两者the Internet和the telegraph。例：As is the case with traditional pharmacies, prescriptions are the cornerstone of a successful on-line drugstore
E选项：错同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
考点：比较
解析：
A选项：as opposed to 是（表对比），与...相对，而不是的语义，而根据后面的语义，twice as much，这里需要的是比较的含义，而不单单是对比，就比如：我有玫瑰花，而她有茉莉花。
B选项：正确。
C选项：pound for pound，修饰的应该是比较的程度，这里变成插入语，有补充说明adult的歧义。
DE选项：will时态错误。
