Please complete Exercise C1 on page 11 T: .Have you finished them? Lets check the answers. (PPT)Keys:1a 2 b 3 c 4 c 5 b 6 b 7 a 8 bT: Well done, youve remembered so much about Mars. Do you have any difficulties while reading? Lets look at some sentences together.Step 4 Explain some important sentences 1There will be various designs for settlers to choose from. 将有许多种设计可供移居者选择。to choose from “从中挑选”。 e.g. 我有很多双鞋子可以选择，但我决定不了选哪双。I have many pairs of shoes _(to choose from), but I dont know which pair _. (to choose) 2. The journey might take only a very short time in space shuttles that travel at half the speed of light.用以光速一半速度飞行的太空穿梭机进行旅程可能只花很短的时间。分析：此句是that连接的定语从句。that引导的定语从句修饰先行词space shuttles, 从句中的动词的人称和数由先行词space shuttles决定。3. Compared with life on Earth, life on Mars will be better in many ways . 与在地球上的生活相比,火星上的生活在很多方面将会更好. compare with意思是“与做比较”。在句中是过去分词短语作状语，此时with和to可通用。 e.g.与我们的那条路相比,这条路繁忙得多。This road is quite busy_ _ ours. (compared with / to )4. Every student will have a computer at home connected to inter-planetary network. 每个学生家有一台连接星际网络的电脑。connect to 意思是“与连接”。这里的connected to 是过去分词后置作定语，修饰computer。当然我们也可以用connect to结构表示“把和连接起来”。 e.g. 江阴大桥把江阴和靖江连接了起来.Jiangyin Bridge _ Jiangyin _ Jingjiang. (connects to )T: Well, boys and gir
