72、keep up with为固定结构，意为“跟上，不落在后面”。3where解析：考查定语从句。先行词为websites，空处在从句中作地点状语，所以用where，相当于on which。4covering解析：考查非谓语动词。提示词为动词，该句中已经有谓语动词(reports)，提示词cover和其所修饰的名词news之间为逻辑上的主谓关系，所以用cover的v.ing形式作后置定语，在此相当于which covers。5suitable解析：考查形容词。这里构成“find宾语形容词(宾补)”结构，所以用suit的形容词形式。6is called解析：考查语态和时态。另一个“我”每天查看的精彩
