[語文] GWD TN10-33RC
TN 10的其中一篇滿長的閱讀 關於地震 考了七個題目
33. The passage suggests that which of the following must take
place in order for any earthquake to occur?
1. Stress must build up.
2. Cool rock must descend into the mantle.
3. A fracture must occur
A. 1 only
B. 2 only
C. 3 only
D. 1 and 3 only
E. 1, 2, and 3
答案是 D
我想問 第二部分(however之後)不是已經說high pressure makes rock so
ductile that it flows instead of cracking 為何還要選3
可從下面這段推斷
In most earthquakes the Earth’s crust cracks like porcelain,
Stress builds up until a fracture forms at a depth of a few kilometers
and the crust slips to relieve the stress. Some earthquakes, however,
take place hundreds of kilometers down in the Earth’s mantle, where
high pressure makes rock so ductile that it flows instead of cracking,
even under stress severe enough to deform it like putty.
以上
懇請解答~
