9月新SAT 考试每日一练题目
2016/9/26-Language & Writing)

今天给大家分享的练习题目是:

Some plant pathologists have turned to genetic engineering to devise new ways of responding to botanical diseases. Plant pathologist William Powell, for instance, teamed up with forest biologist Chuck Maynard to restore North America's population of American chestnut trees, which was decimated in the early 1900s by a fungus known as chestnut blight. A fungus, C. parasitica, contributes to the growth of cankers on the trees' trunks. These cankers, in turn, preventing trees from transporting water from their roots to their branches and leaves. To render American chestnut trees resistant to the blight, Powell and Maynard experimented with the genetic makeup of the trees. The resultant genetically engineered trees are called Darling 4 American chestnut trees, and during the first 15 weeks after infection with chestnut blight, they grow cankers that are much smaller than those that grow on American chestnut trees.

A.No change
B.trunks; these cankers, in turn, preventing
C.trunks; these cankers, in turn, prevent
D.trunks, these cankers, in turn, prevent

答案及解析:
答案:C
解析:Choice C is the best answer because it effectively uses a semicolon to join two closely related independent clauses.
