题目分析：
小题1:观察图示，可知图中描述的是一个男生骑车去学校.本句描述的是客观性事实，故用一般现在时态。主语是是单数第三人称，故谓语动词用单数。短语go to school去学校，by bike骑自行车。故填：Jim usually goes to school by bike.
小题2:根据图示及时间状语提示，可知本句指的是，昨晚八点某人正在读书。故用过去进行时态。填：I was doing some reading at 7:00 last night.
小题3:根据图示及汉语提示，可知本句指的是，每年要砍伐很多树。结合语境可知本句主语是动作对象，故用被动语态。主语many trees表示复数含义，Many trees are cut down by us every year.
小题4:根据图示及时间状语，可知本句描述的是一直持续到现在的动作，故用现在完成时态。主语是单数第三人称，故助动词用has，填：Mike has been ill for two days.麦克已经病了两天了。
