The wind became more and more heavily. 3在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。 如：Who is taller,Tim or Tom? 谁更高，Tim还是Tom? 4. 表示倍数的比较级用法： . A is times the size /height/length/width of B. 如：The new building is three times the height of the old one. . A is times as big /high/long/wide/large as B. 如：Asia is four times as large as Europe. . A is times larger /higher/longer/wider than B. 如：Our school is twice bigger than yours. 5.连用词 much ,a little ,a bit,evenStep 7: Test (课时达标检测题)：一、 Choose1 He feels _ today than yesterday.A. tired B. more tired C. more tireder D. much tired2.
