Watch the micro lesson: How to write a summary. (Optional)2. Finish off B1 in the workbook.1) To begin with, Mars
21、 is extremely cold. Also, its atmosphere is rich in carbon dioxide, so people will not be able to breathe. Still, with no magnetic field, Mars is exposed to much higher levels of radiation. 1) What are the dangers on Mars?2) Since Mars has high levels of radiation, people in Martian cities will prob

Since it is expensive to send materials to Mars, Martian citizens will have to make good use of the planets resources and manufacture everything they need. Settlers will probably follow a vegan diet. Also, people there will not travel much because of the radiation. But they may take advantage of Mars low gravity and invent new sports to entertain themselves.2) Briefly summarize what life on Mars will be like. Include at least three aspects.
