1. 听写包 答案：

these dead penicillin filaments, we can use the chitin in their cell walls to make industrial filters to adsorb heavy metals.

We can put these filters into waste pipes from industrial processes, and use the filters to trap heavy metals, like mercury and zinc.
Later, we can chemically extract the heavy metals and reuse the filter over and over.
Now going back to the adsorption of toxic metals into the body of the fungus, let’s turn our attention to mushrooms.
Like other fungi, mushrooms can adsorb large quantities of heavy metals.
In fact, they may contain up to two and a half times the concentration of toxic metals found in the soil they grow in.
So mushrooms, at least what we see above ground...we can potentially harvest them and then once for all safely dispose of the pollutants contained within them.
In fact, to clean up, especially in the groundwater system, permanently, harvesting mushrooms is probably the best way to go.
For some reason, this hasn’t happened yet as far as I know, but I can easily envision cultivating mushrooms for the sole purpose of detoxifying a large underground ecosystem.
我们可以用这些已死亡的盘尼西林菌丝细胞壁中的角素制造工业过滤器来吸附重金属。
我们可以把这些过滤器放进工业工序的废物管道中，用这些过滤器困住像汞和锌这样的重金属。
稍后我们可以用化学手段提取出重金属，并且一遍又一遍地重复使用这个过滤器。
现在我们回到把有毒金属吸附进真菌内部，让我们把注意力转向蘑菇。
和其他菌类一样，蘑菇可以吸附大量的重金属。
事实上，它们可能包含的重金属是在它们生长的土壤中发现的有毒金属的2.5倍。
所以蘑菇，至少是我们在地面上看到的那些......我们能把它们采摘下来，然后永久地安全地把包含在其中的污染物处理掉。
事实上，为了永久地清洁，尤其是地下水系统，采摘蘑菇可能是最好的方法。
据我所知，出于某种原因，这种做法还没有采用，但我能很容易地想象出只为了去除大片地下生态系统中的毒素而采摘蘑菇的场景。

2.阅读包答案：

比如，有关证据和事实、基本权利和公共利益这样的概念在新闻判断和新闻编写过程中就如同在法庭上一样发挥作用。

3.写作包答案：

The Dragon Boat Festival, also called Double Fifth Festival, is celebrated on May 5th on lunar calendar.It is a folk festival widely spread with a history of over 2,000 years, and is one of the most important Chinese festivals as well. There are various celebrating activities on that day, among which the customs of eating rice dumplings and dragon boat racing are quite important.There are many legends on the origin of the Dragon Boat Festival.Some people think it is to commemorate the poet Qu Yuan, while others say it is to be in honour of Wu Zixu, a famous general during the Warring States period. However, the legend of Qu Yuan spreads most widely. People appreciate highly the noble sentiment and prominent talent of this patriotic poet and are very sympathetic with the ending that he committed suicide by drowning himself in a river.
