13。 This kind of paper was as soft and light as silk but ______ expensive。 chmorethan这种纸和丝绸一样柔软轻薄却要比丝绸便宜得多。先判断出纸比丝绸便宜，所以是less，而比较级只能用much，不能用many。故选A16。 We should prevent pollution ________ happily。 ving为了幸福的生活下去，我们要阻止污染。表示目的，用to + 动词不定式。故选A18。 Sports build the body _______ reading builds the mind。 r当前后两个短句结构一致，表示差异时，用while表示“而”。故选A19。 The mother ________ her son's success in the newspaper。A。 learned about B。 learned C。 heard D。 learned fromA learn about得知B 学习C 听见D 向……学习。
