13. 根据文章的感情色彩解题

考生在第一遍通读时，应在掌握文章大意，弄清作者思路的基础上，着重寻找反映语境褒贬性的标志性词汇或句子，这些标志性词汇或句子往往对文章的语境褒贬性起着决定性的作用。如：

I was so surprised that I was ___47___(speechless). My cousin must have made an effort to get himself into shape. ___48___(As a result), at the point in our game when I’d have predicted the score to be about 9 to 1 in my favor, it was ___49___(instead) 7 to 9 and Ed was 50 (leading).

【解析】surprised 一词道出了情况的转折，我们可以看到这时作者用词的转变。made an effort，get into shape 等这些褒义词的使用对这些空的选择起到了很好的引导作用。speechless, instead 都是由惊讶得出的。
