高三英语Unit2 Crossing limits 教学设计及教案

Sample key:
Yesterday I made a survey among my classmates to see if they would like to take part in a trip to an uninhabited island. Their opinions are divided.
About 60% of the students agree to take apart in the exploration. Some believe that exploration will build up their courage. Some girls think the exploration will make their experience richer. And most students are curious about it and take it a good chance to test their ability of independence.
About 40% of students disagree with the idea. The main reason is that it is too dangerous. The rest of the students take no interest in such activities.
From my point of view, I think life means to experience. And we can be more independent only when we take a positive attitude towards everything. Therefore, I will take part in it.
