问题 During an ice age, the buildup of ice at the poles and the drop in water levels near the equator speed up the earth’s rotation, like a spinning figure skater whose speed increases when her arms are drawn in.
选项 A、like a spinning figure skater whose speed increases when her arms are drawn in
B、like the increased speed of a figure skater when her arms are drawn in
C、like a figure skater who increases speed while spinning with her arms drawn in
D、just as a spinning figure skater who increases speed by drawing in her arms
E、just as a spinning figure skater increases speed by drawing in her arms
答案 E
解析 Each of the incorrect answer choices makes a faulty comparison.
A    Grammatically, the comparison here is
between the buildup of ice... and the drop in water levels... on one hand and a spinning figure skater on the other. However, the appropriate comparison would be either between the figure skater and earth, or between the skater’s rotation and the earth’s rotation.
B    Grammatically, the comparison here is
between the buildup of ice... and the drop in water levels... on one hand and the increased speed of a figure skater on. the other. However, the appropriate comparison would be between the increased speed of earth’s rotation and the increased speed of a figure skater. Furthermore, note that this answer choice nowhere suggests that the skater is spinning.
C    Grammatically, as in choice A, the comparison here is between the buildup of ice... and the drop in water levels... on one hand and a spinning figure skater on the other. However, the appropriate comparison would be either between the figure skater and earth, or between the skater’s rotation and earth’s rotation.
D    When just as is used to mean in the same way as, it must link two independent clauses. The clause beginning who increases speed... is a dependent clause.
E    Correct. In this version just as is appropriately used to create a comparison between the way the buildup of ice at the poles, along with the drop in water levels at the equator, increases the speed of earth’s rotation and the way a figure skater increases the speed of her spin by drawing in her arms
The correct answer is E.
