The government is trying to protect and repair the old city walls, isnt it?反意疑问句有以下几个问题要注意。(1) 陈述部分若用指人的不定代词everyone, everybody, someone, no one, somebody, nobody 等作主语时，其附加问句的主语常用they, 有时也可用he; 陈述部分若用指物的不定代词everything, something, nothing等作主语时，疑问部分的主语常用it;若陈述部分的主语是指示代词 this, that或these, those时，疑问部分的主语一般用it或they。如： 那是一辆小汽车，不是吗？That is a car, _ _?每个人都过得很愉快，不是吗？Everybody had a good time yesterday, _ _? (2) 当陈述句含有few, little, never, nothing, no, seldom, nobody, hardly, neither, tooto, no one等含有表示否定意义的词时，疑问部分要用肯定形式。如： 这个女孩年龄太小不能上学，是吗？The girl is too young to go to school, _ _? 屋子里什么都没有，是吗？There is nothing in the room, _ _? 他们从没步行去过学校，是吗？They never go to school on foot, _ _? (3) 特殊形式的反意疑问句陈述部分为I am时，疑问部分常用arent I 来反问。如：Im interested in reading story books, _ _?陈述部分为祈使句时，疑问部分用will you或wont you, 用will you 多表示请求，用wont you 多表示提醒对方注意。如： 别开门，好吗？Dont open the door, _ _? 准时来，好吗？Come here on time, _ _? 陈述部分为Lets和Let us 时。Lets 表明对话人和说话人是一个群体，所以Lets 的反意疑问句常用shall we; Let us表明对话人和说话人是两个群体，所以Let us的反意疑问句常用will you。如： Lets go home, _ _? Let us go home, _ _? 当陈述部分有had better (not)时，疑问部分用助动词had。如： 他最好去上学，不是吗？Hed better go to school, _ _?你最好不要吃辣的食物，好吗？Youd better not eat hot food, _ _?当陈述部分含有情态动词must时，疑问部分要根据must的含义而确定。当must 作“一定，必须”讲时，疑问部分要用neednt;当must作推测意义“一定，准是”讲时，疑问部分要根据must后的动词原形选用相应的形式。如： 我们必须努力工作，是吗？We must work hard, _ _? 他准是个医生，是吗？He must be a doctor, _ _? 2. try to do sth. 尽最大努力做某事try to do sth. = do ones best to do sth. = try ones best to do sth. 意为“尽某人最大努力去做某事”。因此文中原句也可说成：_3. protect sb. / sth. 意为“保护/ 防护某人/ 某物”。常用短语有：protect from保护免受的伤害 如：我们应该保护身边的动物。We should _ the animals _ us. 尽量保护你的皮肤不被太阳晒。Try _ _ your skin _ the sun.4.
