答案解析：
70. 根据下文B的回答“Just by taking online courses and finishing my homework in time. Sometimes I watched the online classes again when necessary.”(只是通过上网课和及时完成作业。有时在必要时我会再看一遍网课)，可知A是在询问B取得进步的方式，所以用“How did you do it“”来提问，符合语境。
71. 上文A说“I feel worried and hopeless.”(我感到焦虑和无助)，此时B应该给予安慰，“Don't worry”表示“不要担心”的意思，符合语境。
72. 根据下文B的回答“No problem. I am always there if you need help.”(没问题。如果你需要帮助，我会一直在那里)，可知A是在询问当自己有困难时B是否能帮忙，所以用“can you help me”(你能帮我吗)来提问，符合语境。
73. 根据下文B的回答“It means we need to keep temperature increases below 1.5℃.”(这意味着我们需要将温度上升控制在1.5℃以下)，可知A是在询问“Only 1.5℃”这个数字的含义，所以用“What does it mean”(它是什么意思)来提问，符合语境。
74. 根据下文B的回答“The fires lasted for several months.”(大火持续了几个月)，可知A是在询问澳大利亚森林大火持续的时间，所以用“How long did the fires last”(大火持续了多久)来提问，符合语境。
