專八改錯練習(xí)第三十篇：

Many students today display a disturbing willingness tochoose
academic institutions, fields of study and careers in the basis of__1__
earning potential. In an extensive 1989 survey of collegestudents
nationwide, 72 percent of students reported that their primary
objective to attending college was to make more money upongraduation. __2__
This state of mind came with the present generation. Studies show
that the majority of baby boomers attended college to develop
themselves, their critically thinking skills and their personal __3__
philosophies of life.
Nationaly, the number of students going into business-related fields
has sharply increased, and this rise has attributed primarily to __4__
the shift in educational and career priorities. At Duke, economy is __5__
now the most popular major, attracting nearly 15 percent of the under-
graduates, and history majors comprise only 5 percent of undergraduate __6__
population. Thirty years ago the situation was reversed, with economic
and business administration majors together consisting 8.7 percent of __7__
undergraduates and almost 12 percent of undergraduates declared __8__
themselves history majors. The number of English majors has also decreased,
from 9 percent in 1969 to 5.5 percent today.
Degrees in economics are marketed and likely to garner their holders __9__
of high salaries without the added effort of medical or law school. __10__
And given the objectives of current college students, such options
are attractive.

答案及解析(反白可見):
--on
詞組on the basis of 中須用介詞on而不是in。
(attending)--in/of
不要將objective和objective相混淆，object后需加介詞to，但這里應(yīng)用in或者of表示“上大學(xué)的目標(biāo)是……”。
ally--critical
thinking在這里已變成名詞，因此前面應(yīng)該用形容詞critical來修飾，表示“批判性思維”。
4.^attributed--been
attribute作動詞時是及物動詞，通常的搭配是 to attribute sth to sth，因此這里應(yīng)使用被動語態(tài)，加上been。
y--economics
economy表示一個國家的“經(jīng)濟(jì)”，而economics才表示“經(jīng)濟(jì)學(xué)”，因此這里應(yīng)使用economics。
--while/but
and表示順接，而這里缺少的是一個表示對比的連詞，因為歷史系學(xué)生和經(jīng)濟(jì)系學(xué)生在人數(shù)上形成很大對比，所以應(yīng)改and 為while或者but。
ting--comprising/constituting或者 consisting^--of
consist的意思是“包括，由……組成”，一般要與介詞of連用，而comprise或者constitute則表示“組成……”，而且不需要與of連用。
ed--declaring
“almost 12 percent of undergraduates declared themselves history majors”和“economic andbusiness administration majors together consisting 8.7 percent of undergraduates"應(yīng)是并列結(jié)構(gòu)跟隨介詞with，所以這里應(yīng)將declared變?yōu)閐eclaring，與前面的分句保持形式上的一致。
ed--marketable
原句的意思是“經(jīng)濟(jì)學(xué)的文憑是有市場的，有銷路的”，所以應(yīng)該是marketable。
(high salaries)--/
garner后面不需加介詞of，直接說garner sth即可。?
