Topic： the declining heath of maple trees第2套
Next week, we are going to talk about ways to evaluate online sources of information.As you know, while there is a lot of information available on the Internet, it is not all equally reliable. Not all the information you find on websites is accurate, and some of it is even intentionally misleading. When looking for information online, what do you think is the best way to determine whether the information is accurate and truthful?The best way to protect consumers of news from misinformation is through education. in our school, for example, there was a class about evaluating media sources. By constantly questioning journalists' points of view and by considering a variety of sources, we developed a more critical eye and can now better avoid falling victim to propaganda and “fake news".I don't think it's always possible to know for sure whether news is reliable or not.That's why l try to get most of my news from well-known sources that l trust. Those sources may not always have the most up-to-date information, but it is good to know that their reporters have fact-checked the information before they've shared it.
话题: 关于细菌跟随陨石是从外太空来到地球的。Reading不认可是从其他星球上来的,举了三个点反驳。听力说阅读这3个点都不对
Reading
1.细菌很难从它原来居住的行星上面脱落下来，虽然会有石块的碎片撞击别的星球，但是它撞击的力度很难把这个bacteria throw into the space。
2. bacteria could not live alone in the space.因为小行星，就是meteorite，它从原始星球出发到达地球，中间会经历很长很长的时间，细菌在这个meteorite上面很难存活那么久，因为在宇宙中还有比如高温和高压可能会杀死这些细菌。
3.在meteorite进入earth atmosphere的过程中，因为表面会和空气摩擦，会产生大量的热量，这个热量足以杀死bacteria，所以它也很难进入地球表面
