I don’t like this dress.---Neither do I.9. My mom came over as soon as I sat down in front of the TV. (P. 19)as soon as引导时间状语从句，表示“一……就……”，要遵从“主将从现”的原则，即主句用一般将来时，从句用一般现在时I will go as soon as she arrives.10.

Please don't talk so loud while others are working.Tom’s brother was playing the computer games while Tom was studying hard.Kate listens music as she walks in the park.Section B1.
