Such smart homes could even be programmed to detect your health problems, and then give you reasonable advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.2.Create a smart function for your home, and share your creation in the next period.

After graduation, he realized that what farmers needed most was to boost yields in the fields. Yuan was convinced that the answer lay in the creation of hybrid rice, one characteristic of which is that it usually achieve higher output than conventional crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general assumption that this could not be done. Through trial and error, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China was comprised of crops generated from Yuan’s hybrid strains. His innovation has enabled Chinese farmers to considerably expand their output and helped feed the world. Unwilling to retire early to a life of leisure and unconcerned about celebrity or fortune, Yuan continues to turn one vision after another into realities.2. 模仿寫作：Do some research via the Internet and introduce another agricultural scientist, Chen Risheng（陳日勝）, using the structure, expressions and writing techniques you have learnt from the text “A Pioneer for All People”.【設計意圖】任務1是對文本內(nèi)容和詞匯學習成效的檢測。任務2借助文本中學到的詞匯和寫作手法仿寫另一位科學家，提升學生遷移運用詞匯、文體結構和寫作方法的能力。

預設 示例：班上分享個人讀書經(jīng)驗大家好！既然今天是交流讀書體會，那么，我想結合自己的讀書體會和大家聊聊讀書。一個愛讀書的民族，必定是一個文化素質較高的民族;一個愛讀書的人，也必定是一個文化素質較高的人。讀書能開闊我們的視野，提高我們的寫作水平；讀書能提升自身修養(yǎng)，豐富我們的人生底蘊。讀書是我們精神的呼吸，能讓人保持平淡的心境，變得博愛而無私。為了讓我們的生活和心靈變得輕盈一些，我們需要讀書。那么，應該怎樣讀書呢?其一，要擇書而讀。需要的才是最適合的，讀適合的書才能有良多收獲。如果沒有特別需要的書要讀，可以讀經(jīng)典。經(jīng)典是經(jīng)過歲月沉淀下來的人類智慧的結晶，可以讓我們觸摸先賢的思想，以充實自身。其二，要讀而有術。要對好書反復品味，將其內(nèi)化吸收，然后進行批判性閱讀，有自己的思想主張和拓展探究價值判斷;在讀書過程中與作者進行辯論，最后形成自己的思想體系，為我所用，而不是讓自己的腦袋成為別人思想的“跑馬場”。
