168.Because the Earth’s crust is more solid there and thus better able to transmit shock waves,an earthquake of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West. A.of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West B.of a given magnitude will typically devastate 100 times the area if it occures in the eastern United States instead of the West C.will typically devastate 100 times the area in the eatern United States than one of the comparable magnitude occuring in the West D.in the eastern United States will typically devastate an area 100 times greater than will a quake of comparable magnitude occuring in the West E.that occurs in the eastern United States will typically devastate 100 times more area than if it occured with comparable magnitude in the West 能看出D是对的 可是我觉得A也没什么问题 A 中的of a given magnitude 是啰嗦吗？ 路过的NN 们请指点 |
