Section Ⅲ　Grammar and usage 　　　(语法项目——现在完成进行时) 语境中体悟 I have been hearing① a strange sound for a while.It's a deep, loud roar, like a lion's.But there aren't any lions here ...Or are there? Soon I see what has been making② the noise: a howler monkey.Now I feel less worried.Realising that something is moving③ on my shoulder, I turn my head to look at it.Oh no! It's a giant spider! I brush it off and it runs under some leaves.I try to bat away the huge insects, which have been flying④ around my head in a black cloud for quite a while.I pull off the headset and I'm back in my living room.Thank goodness! I have been given⑤ the latest virtual reality headset and, for the last twenty minutes, I have been using⑥ it to explore the Amazon.This is an amazing experience and a reminder of how many species there are in the rainforest.We must do all we can to protect it. [语法入门] 句③为现在进行时，表示动作现在正在进行； 句⑤为现在完成时的被动语态，现在完成时一般表示动作已经完成； 句①②④⑥是现在完成进行时，表示动作开始于过去，持续到现在，可能还将继续下去。 学案中理清 一、现在完成进行时的用法　 1．表示从过去某一时刻开始一直持续到说话时还在进行，或可能还要继续下去的动作。通常和“for＋时间段”或“since＋时间点(或从句)”的时间状语连用。 I've been waiting for an hour but she still hasn't come.　我已经等了一个小时，但她还没有来。 She has been playing tennis since she was eight. 自从八岁以来她一直在打网球。 2．现在完成进行时在上下文语境充分时也可不用时间状语。这种现在完成进行时多指“刚才”或“近来”发生的动作，一般不再继续，并往往含有一种直接的结果。 You've been working too hard. 你工作太辛苦了。 You've been smoking again. 你又抽烟了。 Who's been insulting you? 谁冒犯你了？ 3．有时现在完成进行时所表示的动作并不是一直在不停地进行，而是在断断续续地重复。这时现在完成进行时可用于瞬间动词。 He's been shaving since last year. 他从去年开始就一直刮胡子。 You have been saying for a year that you will study abroad.　整整一年你都在说要出国学习。 4．强调动作延续时间的长久或带感情色彩。 She has always been working like that. 她一贯是那样工作的。 Tom's hands are very dirty. He has been repairing the car. 汤姆的手很脏。他一直在修汽车。 |图解助记| 二、现在完成进行时与现在完成时的区别　 1．在不使用时间状语的情况下，现在完成进行时的动作不一定已经完成，很可能还要持续下去，而现在完成时一般表示动作已经完成。现在完成进行时强调动作的延续性，而现在完成时强调动作的结果。 2．现在完成进行时往往表示动作在重复，现在完成时一般表示一次性动作。 3．现在完成进行时比较生动，有时带有强烈的表扬或厌恶等感情色彩，而现在完成时往往只说明一个事实、一种影响或结果，平铺直叙，没有什么感情色彩可言。 |名师点津|　有些动词不能用于现在完成进行时，但可用于现在完成时： 状态动词：be, have, exist； 情感动词：like, love, hate, dislike； 感官动词：see, hear, know, feel, sound； 短暂性动词：finish, marry, come, go等。 They have gone to Shanghai. 他们已经去上海了。 They have been to Shanghai. 他们曾去过上海。 They have already finished the work. 他们已经完成了这项工作。 应用中融通 用所给动词的适当形式完成短文 Some experts ①have_been_doing (do) some research on robots these years.Robot teachers are now very popular with pupils in some primary schools in South Korea.②Compared (compare) with human teachers, robot teachers are more patient.In addition, they ③have_been_standing (stand) there since they were created and never feel tired.④Equipped (equip) with microphones and video cameras，the robots teach students as teachers.Researchers found that the English-teaching robots helped raise students' interest in the language.More and more students gradually got their grades ⑤improved (improve) in exams.Meanwhile, other robot teachers，which can teach math, science and art, ⑥have_been_developed (develop) so far as well.Many people think these robot teachers should be used in faraway village schools so that the children who ⑦have_been_looking (look) forward to better education these years can also receive good education.⑧To_give (give) rural school children more learning chances, the South Korean government ⑨has_expressed (express) great interest in developing these robots already.No doubt there will be more and more robot teachers ⑩working (work) with students.Perhaps they will completely replace human teachers one day in the future.Who knows？ I was equipped with an artificial hand, but it did not feel like part of me.　我安装了一只假手，但感觉它不像是我(身体)的一部分。 ★equip vt.配备；使有能力 |用|法|感|知| •(主旨升华句)We should equip ourselves with the high-positive poses and make our every day beautiful and energetic！　我们应该用高度积极的姿态装备自己，让我们的每一天变得美好且充满活力！ •(写作增分句)The path to success is a rocky path and you need to be prepared and fully equipped for the trip.　成功的道路是艰难的，你需要为此做好准备，充分装备自己。 [归纳点拨] (1)equip ...with ...　　 用……装备……；让……具备(知识、技能等) be equipped with 配备着/具有……(常用过去分词作状语)　　　　 　equip sb./sth.for ...　　 为……而武装某人；为……而装备某物 be equipped to do sth. 能够胜任做某事 (2)equipment n.
