Activity 4 Of all the modern inventions, the camera impresses me most. It was invented in the late 20th century and has developed rapidly ever since. Not only is it used for recording beautiful moments, but it also brings great convenience to ordinary people. Before it came into being, people had to draw paintings to record views, which took up much time and energy. Thanks to this wonderful invention, our lifestyle has been greatly improved. It is so useful that modern people can hardly get used to living without it. Pronunciation Pause and sense group & Stress, pause and rhythm 1. Sense group(意群)：指根据句法结构与语义完整性划分的语言单位，一个意群表达一层相对完整的意思，是语句停顿划分的依据。 意群划分：①逗号后面划/；②介词短语(in, by, for, about)前面划/；③从句引导词(that, when)前面划/；④长主语说完之后划/。 2. Pause(停顿)：朗读时在意群边界处进行短暂间歇，分为句中停顿与句末停顿，用于区分语义层次，提升语句可读性。①斜线/：短停顿，稍微顿一下，不用换气，语调不变；②句尾句号：长停顿，换气，语调降下来。 要求：只在斜线处停顿，不要逐词停顿。 Pronunciation Pause and sense group & Stress, pause and rhythm 3. Stress(重音)：在连贯语句中：①重读：名词、实义动词、形容词、副词、数字；②弱读：冠词、介词、助动词、人称代词、连词。 4. Rhythm(语流节奏)：由重读音节、非重读音节交替排布，配合规律停顿形成的英语韵律特征，是自然流利朗读的核心要素。 注意：重读单词读重、读慢，非重读单词读轻、读快，轻重交替均匀朗读，不要每个词读得一样重。 Read the sentences. Pay attention to the sense groups and the pauses in each group of sentences. Activity 1 1. The light bulb was invented / by Thomas Edison. The light bulb was invented / by Thomas Edison / in 1879. As we know, / the light bulb was invented / by Thomas Edison / in 1879. 2. There are a few steps / to follow. There are a few steps / to follow / in the invention process. The scientist tells us / there are a few steps / to follow / in the invention process. Amazing Inventors We’re in'ventors. / We have made 'great in'ventions / since our 'birth. / Our in'ventions can go 'slow / or 'really 'fast. / And there are some in'ventions / from the 'past. / Our ma'chines go over 'land / and through the 'air. / Our in'ventions can 'take us 'anywhere! Our in'ventions / 'fly us 'high / and 'far away! / And our in'ventions / are 'here to 'stay! Read the text. Pay attention to stresses, pauses and rhythms. Activity 2 Language points 1. It is said that it was invented in 1879. Do you know who the inventor was? 据说它发明于1879年。你知道发明者是谁吗？ 【点拨】(1) 固定句型 It is said that＋从句，意为“据说······”，it是形式主语，that从句为真正的主语；同类结构还有It is reported that(据报道)，It is believed that(人们认为)。 (2) was invented是一般过去时的被动语态，结构为：was/were＋过去分词。 (3) who引导宾语从句，宾语从句必须使用陈述语序，不能用疑问语序。 2. It is surely more convenient to travel by car than on horseback. 乘汽车出行肯定比骑马更方便。 【点拨】by car 乘坐汽车 on horseback 骑马 3. —These great inventions have truly changed the world, haven’t they? —They certainly have.——这些伟大的发明真的改变了世界，不是吗？——的确如此。 【点拨】(1) 此句为反意疑问句，遵循“前肯后否，前否后肯”原则。 (2) 反意疑问句的答语依据事实回答，本句肯定事实，“They certainly have”相当于 “Yes, they have”。 (3) have在此处是助动词，帮助构成完成时态，不是实义动词“拥有”。 Exercise 一、用所给单词的正确形式填空 1.
