英語六級-攻克閱讀關(guān)鍵句111. By capping her grades at 94 while most ot

111. By capping her grades at 94 while most other teachers grade on a scale that tops out at 100, your teacher could jeopardize a student's chance of getting a scholarship or getting into a top college.

譯文　

如果你的老師將最高分?jǐn)?shù)定在94分，而其他大多數(shù)老師評分范圍的最高分是100分，那么她這樣做可能會危及學(xué)生得到獎學(xué)金或進入名牌大學(xué)的機會。

點睛　

本句的主干是...teacher could jeopardize...chance...。句首的介詞短語By capping...是句子的方式狀語，其中while引導(dǎo)的是比較狀語從句，that引導(dǎo)的是scale的定語從句。由or所連接的getting a scholarship和getting into a top college是介詞of的并列賓語。
cap在句子中作動詞，意思是“規(guī)定限度”。如：
This kind of mortgage is capped. 此類按揭被規(guī)定了額度。
top out的意思是“以……為頂點；封頂”。如：
Interest rates topped out at 4 percent. 利率在百分之四封頂。
jeopardize的意思是“使受到傷害、損失；使陷于險境”。如：
The security of the operation has been jeopardized by one careless person. 作業(yè)安全讓一個粗心大意的人給破壞了。
