There's grandma. 瞧！奶奶在那里 I can see you!“我能看到你！” He spent the entire afternoon watching a cricket match.他整个下午都在看一场板球比赛。 The role of scientists is to observe and describe the world, not to try to control it.科学家的任务是观察和描述这个世界，而不是试图控制它。 On the bus I always manage to glance at the headline in the newspaper.在公共汽车上我总能设法匆匆看一眼报纸大标题。单词和短语精讲(2)look作为系动词用，意为“看起来”，后跟形容词。例如:You look well/fine/healthy.你看起来很健康。The teacher looks happy. 老师看上去很高兴。She looks pale. 她面色苍白。【拓展】look at 看着 ; 看 ; 看望 ; 看待 look in 拜访：进行短暂访问：把注意力转向…look for 寻找；希望得到 look on 在一旁观看，袖手旁观；把眼光投向(某物或某人)look out of 向/朝 ... 看 look out for 小心；搜寻(某人或某物);试图得到(某物)look oneself 显得健康或情绪正常 look to 依靠〔指望〕(某人或某事)look after 照看，照料 look around 四下环顾：到处寻找单词和短语精讲4. help的用法(1)help 当动词用时，是指“帮助、帮忙”的意思，主要句型有：①help sb.
