七下Unit4Reading一 词汇讲解1. They help us in many ways. 他们在很多方面帮助我们。 in many ways 意思是“在很多方面”；此外，还可以用in 。way 表示“以方 式”，如in a clever way, in a simple way.e.g. Tom is a big man in many ways. Tom在很多方面都是位了不起的人。He solved the difficult problem in an easy way.他用一种简单的方法解决了那道难题。2. They keep the air cool and clean. 他们保持着空气的清爽与洁净。Keep sb/sth. + adj. 意思是“使（某人或某物）保持。”，具有同样用法的动词还有make, e.g. make the little girl unhappy.e.g. Its necessary for us to make our country more powerful.对我们来说，使自己国家变得更强是必需的。3. A lot of furniture is made of wood.1) furniture 意思是“家具”，为集合名词，当单数使用，没有复数形式。“一件家具”应表达为 a piece of furniture.e.g. All the furniture in this shop is from Europe.所有这家店里的家具都是从欧洲进口的。2） be made of 意思是“由。制造”， of 后接表示材料的名词。The desks and chairs in our classroom are all made of wood and metal.我们教室里的课桌和椅子都是由木材和金属做出来的。4. But we cut down millions of trees every year.但我们每年都砍下了数以百万计的树木。millions of 意思是“数以百万计”，后接名词，表示概数，如millions of trees；当million 前面出现具体数字十，如two, 应表达为 two million trees.e.g. Millions of tourists visit Guangzhou every year.每年都有数以百万计的游客来广州游玩。二 句子解析We should stop doing this if we dont want a world without trees.如果我们不想要一个没有树木存在的世界，就应该停止这样做。If “如果”，引导条件状语从句。主句与从句的时态常遵循“主将从现”原则。即：主句使用一般将来时（也可使用情态动词），从句使用现在时。e.g. We will/can go to visit Tom if the weather is fine tomorrow.如果明天天气好的话，我们将（可以）去Tom家拜访。三 经典句记忆1. They keep the air cool and clean.他们保持着空气的清爽和洁净。2. I know trees also make our lives more convenient.我知道树木也使我们的生活更加便利。3. In fact, we get a lot more from the trees.事实上，我们从树木上得到的还远不止这些。4. I cant imagine a world without trees.我无法想象一个没有树木的世界（是怎么样的）。Grammar现在进行时语言观察1. .Listen! Tom is playing the piano in the room.2. -What are you doing at the moment? -I am reading a book.3. The workers are building the mansion these days.4. When are you leaving for London?要点归纳通过上述四个例子，我们可以得出现在进行时的以下用法：1. 当句中出现“listen, look, be quiet”等祈使句时，即强调事物正在进行，需使用现在进行时；另外，与部分时间词“right now, at the moment, now”搭配时，也常用现在进行时；2. 当对方用现在进行时提问时，通常用现在进行时回答；3. 现在进行时可以表示现阶段一直在发生的动作，常搭配的时间词有“these days, this week”;4. 现在进行时可表示即将要发生的动作。Speaking and Writing口语经典句型1. Trees are really important in our daily lives.2. Trees keep the air cool and clean.3. Trees help us in many ways.4. Trees take in harmful gases from the air and produce oxygen for us to breathe.5. Trees are major fighters against air pollution.写作策略指导我们一般使用现在进行时对图片进行描述，但当所描述的图片内容较多或需描述较多图片时，为了使描述更具条理性，一些适当的衔接必不可缺。1. 描述同一图片中不同事物的衔接方法。1） 从人物方面进行衔接。常用句型;Some, others; One, and another (two); one/two of them, and the other(s)2） 从时间方面进行衔接。常用连词：While(A is doing while B is doing); at the same time,3） 从方位方面进行衔接。常用方位词；On the left(right) of the photo, in the middle of, near (sb./sth), beside, next to, behind, in front of2. 描述多张图片中事物的衔接方法：从事物或动作发生的顺序方面进行衔接。如：First(ly) second(ly) at last, finally, after (doing); and then; the first/second step is toMore Practice一 词汇讲解1. Its home to thousands of animals, birds and insects.它是成千上万动物，鸟类及昆虫的家。Home to sb./sth. 意思是“某人或某物的家”。Thousands of 意思是“数以千计，成千上万”，用法与millions of 相同。e.g. It is the home to thousands of orphans. 这是成千上万名孤儿的家。2. As a result, the number of kinds animals, birds, insects and trees in the world is decreasing. 因此，世界上动物，鸟类及树木的种类数量在不断减少。 The number of 意思是“。的数量”；a number of意思是“一些，许多”。 e.g. Here are a number of books for you. The number of them is 20. 这里有一些给你的书，数量是20本。3. We must do our best to protect the Amazon rainforest. 我们必须尽自己最大的努力去保护好亚马逊雨林。 Do ones best to do 意思是“尽某人最大努力做。”；意思与“try ones best to do ”相同 e.g. We should do our best to help the elderly people of no family. 我们应尽力帮助那些无家可归的长者。二 句子解析1. However, people are destroying the area by cutting down many of the trees.然而，人们正在以滥伐的方式破坏着这片土地。By doing 表示“通过。手段或方式”，在句子中充当状语。e.g. He makes a living by collecting rubbish. 他靠捡垃圾为生。2. Many living things lose their homes because of deforestation.由于森林砍伐，很多生物都失去了他们的家园。Because of 意思是“因为”，后接名词，代词或动名词，如because of doing sth; 而because后接句子。e.g. Many living things lose their homes because people keep cutting down trees.由于人们砍伐森林，很多生物都失去了他们的家园。三 经典句记忆We must do our best to protect the Amazon rainforest.我们必须尽自己最大的努力去保护好亚马逊雨林。 课堂评价Reading一 根据句意和所给的首字母完成下列句子。1.
