Do you think_______ I should attend the lecture?” she asked me.
A)that
B)whether
C)if
D)when
为什么选A不选B?
翻译过来是“你认为我应该去参加演说吗?”that表从句,whether表是否,就成了“你认为我应该去还是不去参加演说?”虽然中文两句没什么差别,可是一般疑问句的从句中就应该是单项而不是表是否的whether,即do you think 与whether语意重复
Jim knows little of mathematics,______of chemistry.
A)and still less
B)as well as
C)no less than
D)and still more
为什么选A不选C?JIM对数学和化学都知之甚少.C项后面不能接of的
Calculations,which are astronomically exact,have been made _____ with the use of computers
A)possible
B)it possible
C)possibly
D)to be possible
为什么选A不选D have been made后应当接形容词不是不定式
According to the periodic table,________ still some elements undiscovered .
A)there seem to be
B)it seems to be
C)it seems that
D)here seem
为什么选A不选B
根据语意,句中没有it具体指代,或者说没有it作形式主语的必要.
不管我答得对不对,都很烦那些说自己[绝对]对的人.
