year”可知，事情发生在过去，故此处用一般过去时。5hidden根据空后的名词delights可知，空处应用形容词hidden作定语。6surroundingsurround和句子谓语float之间没有连词，故用非谓语动词形式，又因surround和句子主语“The varied shapes of the clouds”之间构成逻辑上的主谓关系，故用现在分词作状语。7atake a

bacteria”可知，应填are。3powerful此处应用形容词作定语修饰名词短语，故填形容词powerful。4health介词后跟名词、代词或动词ing形式作宾语。human health意为“人类健康”，作介词to的宾语。5theability被不定式短语“to easily turn treatable infections into

time”可知，treat所表示的动作发生在过去，且动词treat和infections之间是被动关系，故用一般过去时的被动语态。.短文改错After I elected chairman of the students union of our school, I decided to start a school English newspaper for us student.
