在prep07版,TEST1 第44题中
Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat
from the Earth's interior and producing energy on a commercial scale, enough for efficient
generation of electricity and heating factories and homes.
(A) and producing energy on a commercial scale, enough for efficient generation of electricity and
heating
对A选项错误的理由中,有一条是说have succeeded...and producing ....前者是动词结构,后者是动名词结构不平行;
可是能否把producing和mining看做并列呢,那问题就在于succeed 后的 介词in 能否在并列时省略呢?推而广之,是否不及物动词并列是其后的介词都不能省略呢?
