2021年11月13日托福【综合写作】回忆和解析含范文！

　　2021年11月13日托福写作回忆和解析含范文！本文由环球教育南京学校李敏老师提供，本次考试综合点评：这次托福考试写作部分整体难度适中。

　　其中，综合写作考查天文类，围绕火星是否有液态水展开讨论。这个主题虽然有些难度，但是听力、阅读和综合写作的练习题中都出现过，认真做过练习的同学应该还是比较容易掌握内容的。

　　独立写作考查家庭教育类话题，绝对词题，同学们对这类题型还比较熟悉。类似的题目在2015年出现过。

　　综合写作

　　话题分类天文类

　　考题回忆总论点火星上是否有液态水

　　阅读部分阅读总观点：火星上的streaks不是液态水留下的

　　阅读分论点一：可能是陨石撞击形成的

　　阅读分论点二：火星的低温并不可能存在液态水

　　阅读分论点三：探测器并未检测到液态水

　　听力部分听力总观点：是液态水

　　听力分论点一：streaks的形状并不符合陨石撞击的情况。按理说，陨石撞击形成的痕迹应该偏圆偏大，而非streaks

　　听力分论点二：火星低温不代表一直低温，可能有固态水在偶然的高温环境下变成液态水，所以形成的痕迹成streaks状

　　听力分论点三：环绕火星的探测器是一直在运转的，那很有可能没探测到是因为时机不对，而不是真的没有

　　解题思路按照总分结构，做好阅读部分的总结并展现出听力对应阅读提出的反驳。

　　参考范文The materials focus on whether liquid water once existed on Mars. Although photographic images show streaks on the surface of Mars, the author maintains that these streaks were not shaped by liquid water, which contradicts with the lecturer’s standpoint.

　　First, the passage points out that the streaks may be the result of meteorite strikes. But the professor challenges this idea by providing the truth that the traces of meteorite crashes should be large and circular craters rather than streaks. Thus, this is contrary to the writer's notion.

　　Second, the passage asserts that the temperature on Mars is too low to allow liquid water to exist. Again, this is retorted by the lecture, which asserts that Mars was not in a low-temperature environment all the time. When the temperature rose, solid water might become liquid and formed streaks as its traces. Obviously, this forms a sharp contradiction against what is stated by the writer.

　　Finally, the writer claims in the passage that the detector on Mars did not find any liquid water; conversely, the speaker refutes it by proposing in the listening passage that it might not be the right time when the detector was in operation. Thus, the absence of clues of liquid water can not indicate that liquid water never existed.
