She is so beautiful that all boys want to make friends with her. My sister is too young to go to school. =My sister is so young that she can't go to school. 单词和短语精讲10. 提建议时，常用句型有: (1)Why don’t you…? 表示“为什么不”， 后接动词原形。e.g. Why don't you have a cup of hot water？为什么你不喝一杯热水？(2)Why not…?表示“为什么不”，和Why don’t you…?相似，后接原形动词。e.g. Why not have a cup of hot water？为什么你不喝一杯热水？(3)How about/What about…?表示“...怎么样？”，后面跟动词的ing形式。e.g. How about staying at Bart's overnight? 在巴特家过夜, 你看怎么样?

I don’t know how to increase my reading speed.这里how to increase my reading speed是“疑问词+动词不定式短语”的结构，在句中作谓语动词know的宾语。这种用法相当于一个从句how I can increase my reading speed的简化形式。能这样用的还有：what/which/when/where/who/whether to do。e.g. What to do is not decided yet. 该做什么还没有确定。 Do you know when to start? 你知道什么时候开始吗？ I showed her which button to press. 我告诉她应该按哪一个按钮。 The question is how to carry out the plan. 问题是怎样执行这个计划。 单词和短语精讲13. increase 意为“增加，增长”。常用短语：increase to “增加到…”，后接具体增长后的数值。increase by “增加了…”，后面增加的百分数或倍数。e.g. The population of our country has increased to 1.3 billion.
