2、At the symposium,the PrimeMinister said that the Korean economy is facing greater economic hardshipsnowadays due to external variables such as soaring international crude pricesand the strengthening of the Korean won,__ a prolonged increase in exports.


　　A.despite 和 B.in spiteof 是介詞,都表示“盡管”,前者語(yǔ)氣緩和,后者比較強(qiáng)硬,后面需要用名詞作賓語(yǔ)；C.although和 D.though 都是引導(dǎo)讓步從句的連詞,后面需要跟句子.
　　這里的a prolongedincrease in exports（出口長(zhǎng)期的增長(zhǎng)）是名詞短語(yǔ),前面只能用介詞despite 或in spite of,這是兩個(gè)同義詞,意思一樣.從修辭角度來(lái)說(shuō),這兩個(gè)詞中,前者語(yǔ)氣緩和,后者語(yǔ)氣較強(qiáng).
　　though和although在意義上幾乎毫無(wú)區(qū)別,但文體上后者是較正式用詞,語(yǔ)氣比though強(qiáng).如果此處是 there is a prolonged increasein exports,就可以選用其中的一個(gè).
