(to) do sth. 帮助做 He often helps me with my English.= He often helps me study English. 他经常帮助我学习英语。4. over and over again是固定搭配，译为：反复的；多次”， 还可以说 over and over。例如：They sang the song over and over. 他们反复的唱着那首歌。 They call over and over again but nobody answered. 他多次打电话，但没人接。Task 3.

James White believes that robots wont be able to do the _ things as we can. For example, he thinks that robots will _ be able to wake up and know where they are. Which side do you _ with?讲解重点单词或短语：1. Some robots are very human-like. 一些机器人十分像真人。在human-like （形似真人的；真人一样的）一词中，-like 为形容词后缀，用在名词之后，与其构成一个完整的形容词，表示“ 形似的；像一样的；类似于.的”。又如： a bird-like building （像鸟一样的建筑） a cabbage-like vegetable（一种形似卷心菜的蔬菜） the ball-like thing on the top of the building（楼顶上那个像球一样的东西。） 2. be able to 能够做某事 We hoped that we should be able to do that. 我们希望我们能这样做。 They may be able to give me some ideas. 他们会给我一些建议的。be able to 和 can 的区别 (1) be able to 用于表能力，并可用于多种时态和非谓语动词短语，而can 只有一般现在时和一般过去时两种时态。 (2) can 可用于人或物作主语的句子中；而be able to 的主语只能由有生命的名词充当。 (3) can 常指客观上能够；be able to 更侧重于“克服一定困难”、“经过努力”、“有能力”做成某事。3. the same as 和一样 She looks the same as Lucy. They are the twin sisters. 她看起来和露西长的一样。他们是双胞胎姐妹。 反义短语： be different from(阅读策略：有选择地精研细读有关章节或段落，解决疑难之处。) Task 6.
