第一课时 Reading: Who am I? 主题语境：人与社会-----话题 语篇类型：说明文 一、

目标确定的依据

1．文本分析

本单元的主题是人与社会，涉及的话题是计算机。从文体上来讲，属于说明文，Reading中以別致的标题 Who Am1？引起学生的好奇心，使学生迫不及待地阅读这篇文章，并努力猜出“I＂是 computers，从而对文章的内容印象深刻。文章以第一人称的形式按时间先后顺序讲述了computers的产生、发展和现在，并用拟人化的口吻表达了 computer乐于为人类服务的精神。文章分为三个自然段。第一段按照时间顺须讲述了电脑在不同时期的发展状况。第二段从电脑的记忆储存和外形上讲述了电脑的变化。第三段描述电脑的应用。

通过这节课的学习，学生增加另外有关计算机等方面的的知识和相关的词语，并理解了计算机的发展史及其广泛的应用，从而激发学生对科学探索的兴趣。

学情分析

本节课的教学对象为高下学期的学生，在经历了必修1的学习过程之后，学生已经对高中的英语学习有了初步的了解和感知，但是仍然需要训练和提高语篇的理解，归纳和分析的能力。本节课的一系列活动，就是为学生的语篇阅读打开一扇商户，培养学生的语篇意识，使其更全面的理解文章内容，归纳主旨大意。

学生在前一节课的词汇学习中，已经掌握了文中所出现的大部分生词，这为本节课的阅读扫清了障碍，能让学生更好的专注于语篇结构的理解，高一学生活泼好动，思维活跃，愿意积极的投入到思考中。

News from 21st Century.

Here is a piece of news from 21st

Century , read it quickly, trying to find out the advantages of

HUAWEI Mate X.

Huawei has launched(发布) its foray into foldable smartphones, with

the

Huawei

Mate

X

officially unveiled at

Mobile

World Congress

2019

as a

competitor

to Samsung's Galaxy Fold and a

device that

could focus on productivity.

The company’s CEO of consumer business, Richard Yu, unveiled the new Huawei Mate X, on stage, saying: “We bring you the future of design, the future of technology.” Here are the advantages 1.

Eagle wing folding（鹰翼式折叠）: 180 degree free folding Unlike the Samsung folding phone, the Galaxy Fold, which opens inwards, like a book, the Huawei phone opens outwards. Given this different functionality, Huawei has managed to make this device incredibly thin.

The foldable screen of the Huawei Mate X is folded around the outside of the device, with te help of a patented hinge with over 100 components the company said.

2.5G,1GB movie in just 3 seconds

The phone will run on Huawei’s Kirin 980 processor

and Balong 5000 chipset, which supports 5G. The company said the super-fast chipset will allow users to download a 1 gigabyte movie in just 3 seconds. The Mate X is Huawei’s first 5G-enabled smartphone. Huawei said it has an advantage over other companies launching 5G devices because it provides the full-range of equipment needed to get wireless networks up and running. 3.Multi-window use（多屏多任务交互）

The device boasts of two column browsing side by side or multi-window use. 4.Fastest charging To power the phone, the device has dual batteries which make up 4,500mAH. It also features Huawei's new SuperCharge 55W to make this device the fastest charging phone in the industry. You should be able to get 85 percent power off a mere 30-minutes of charging. 5.live preview（拍摄时双屏实时预览）

The lopsidedness of Huawei's folded displays are due to a vertical camera bar that runs along the back of the phone. This houses three cameras—a 40 MP main camera, a 16 MP wide angle lens, and an 8 MP telephoto—and an LED flash, and a power button. It features a camera system that can play the role of both front and rear cameras. It also offers mirror shooting that lets you see the picture while you take it.

The new product is expected to go for the market and be available to customers in late April this year. however, most experts think the market for the new product

is very limited, with its estimated price of €2299,

which greatly falls short of the expectation of average consumers.
