Question

Unfortunately, the research was limited __________ increasing economic profits, _________ protecting the environment.

A．to; other than

B．by; rather than

C．to; rather than

D．by; more than

Answer 1

C

試題分析：原句意思，不幸的是，這份研究局限于提高經(jīng)濟(jì)利益，而非環(huán)保。be limited to 局限于 other than 不同于rather than 而不是 more than 多于，故選C。
點(diǎn)評：解答此類題型要先理解題干要表達(dá)的意思，再分析各個選項中詞組的詞義，從中選取適合語境的一個。在平時的學(xué)習(xí)中，要重視對詞組的總結(jié)和記憶。
