Q10:
Antarctica receives more solar radiation than does any other place on Earth, yet the temperatures are so cold and the ice cap is reflective, so that little polar ice melts during the summer; otherwise, the water levels of the oceans would rise 250 feet and engulf most of the world’s great cities.
A. is reflective, so that little polar ice melts during the summer; otherwise,
B. is so reflective that little of the polar ice melts during the summer; were it to do so,
C. so reflective that little polar ice melts during the summer, or else
D. reflective, so that little of the polar ice melts during the summer, or
E. reflects so that little of the polar ice melts during the summer; if it did
選答案 B是有問題的。were it to do so 可謂 wordy and awkward, 且it的先行詞指涉模糊不清。
C 較可接受。 so reflective 之前的be 動詞是可省略的,尤其是在附屬子句中的對比句為然。
