1、SPACE EXPLORATIONLead inAfter learning the text on P40,what do you think of space exploration?necessary&beneficialdangerous&difficultcost much money and time.V.SIs exploring space a waste of time and money?Pre-readingWhat should we focus on when reading an argumentative essay?thesis statemetevidence

2、Read the essay and find the relative information.Is exploring space a waste of time and money?Countries around the globe are spending billions of dollars and lots of time on various space missions,whether to Mars or other planets much further away.Some people argue that we should stop wasting time a
