Answer 1

Dear Mr Sun，
     Knowing that our library is going to buy books，I d'like to give some suggestions．（高分句型一）What we need most are popular science books．Usually popular science books explain basic parinicples of nature in a simple and interesting way．They help us understand science subjects better and arouse our curiosity about scientific discoveries．
     In addition to reading for knowledge，we read for fun and inspiration．That is why I recommend anther category of literary books，classic works written by masters，present great thoughts through fascinating stories and language．（高分句型二）They not only offer us to think critically．
     I'll be glad if you can consider my recommendation．
          Yours sincerely，
           Wang   kai
