一、现在完成时的构成现在完成时的谓语构成是“have/has+动词的过去分词”。二、现在完成时的用法1. 表示过去发生的动作对现在的影响或产生的结果。常与just, already, every, never, yet等副词连用。He has had breakfast. 他吃了早饭了。（对现在的影响是不饿了）She has spent all f her mney. 她把所有的钱都花了。（对现在的影响是没有钱了）
2. 表示一个从过去某个时间开始，延续到现在并可能持续下去的动作或状态，常与since或fr引导的时间状语连用。since后面加时间点或从句（从句时态常用一般过去时），fr后加时间段。They have lived in Beijing fr 5 years. 他们在北京住了五年了。He has learned 200 wrds since he was 7 years ld. 从他七岁开始，他已经学了200个词了。
（2）in/n+a/the+交通工具名词 Hw abut ging there in a car?乘小汽车去哪儿怎么样？We want t g t the z n a bike.我们想骑自行车去动物园。（3）take+a/the+交通工具名词 We'll g t Lndn by train, and then take a bus.我们将坐火车到伦敦，然后转乘公共汽车。（4）walk t+某地/g t +某地+n ft 步行去某地He ften walks t schl.他经常步行去上学。
三、现在完成时与一般过去时的区别1. 现在完成时强调过去发生的动作或状态对现在造成的影响或结果，而一般过去时强调的是过去某一具体时间的动作或状态，与现在没有关系。I have lst my key. 我丢了钥匙。（对现在的影响是没有钥匙了）I lst my key. 我丢了钥匙。（过去钥匙丢了，没说明现在是否有钥匙）2. 现在完成时表示自过去延续到现在的行为，而一般过去时着重说明过去某一时间的某一具体动作。所以现在完成时可与包括现在在内的时间连用。而一般过去时只能与表示过去某一具体时间的时间状语连用，如yesterday, last week, three days ag。We have learned English fr three years. 我们已经学英语三年了。We learned English here three years ag. 三年前，我们在这儿学习英语。
1. Kitty’s cusins, Lucy and Simn, have cme t Garden City t visit the Li family. 基蒂的表妹露西和表弟西蒙到花园城来拜访李家。动词不定式（短语）作目的状语动词不定式短语t visit the Li family在句中作目的状语。I wrte it dwn t remember it. 为了记住它，我把它写了下来。T finish the wrk n time, they started wrking early. 为了按时完成工作，他们早早开始工作。
