据报道,近日公安部统一指挥浙江、山东、河南等地公安机关,首次全环节破获了一些特大利用地沟油制售假食用油的系列案件,一条集掏捞、粗炼、倒卖、深加工、批发、零售等六大环节的地沟油黑色产业链浮出水面。地沟油,这个被不少中国人唯恐躲之而不及的东西,在美国、荷兰、英国甚至阿联酋用来生产生物柴油,燃烧后产生的二氧化碳排放量要比传统柴油少60%——80% ;荷兰对废油进行脱氧处理,经过一系列有机化学反应后,提炼成“可再生飞行燃料”。对此,我国不少网民呼吁,要让地沟油“变废为宝”,给它找一条出路。 据此,为了让同学们树立“变废为宝”理念,增强生态文明意识,某校一研究性学习小组准备开展一系列探究活动,请你一起来参与。

Tanzania Tarangire is a national Park which lies in Tanzania.The park itself covers an area of around 2,850 square kilometers, making it the sixth largest park of its kind in the country.I recently visited Tarangire to see what it was like….

One of the first sightings upon entering the park which I found was a huge herd(群)of elephants. Our guide told us that Tagrangire was probably the best place in Tanzania to find large herds of elephants, and that their population in the park was around 2,500.We continued to watch the elephants as they stood under trees and scratched themselves against the trees to hit the spot of an itch(痒处).

To the right of the elephant herd, we noticed a big tree! Our guide informed us that this was a Baobab tree and that they could live for hundreds of years.Compared with this tree, the elephant just looked like dwarfs(侏儒)! We were informed that Tarangire was one of the best National Parks in Africa to see so many Baobab trees.

As we continued our drive through the park, we finally reached a watering hole.Our guide warned us that there were lions all around us.It took us all a while to find them, but there they were! Most of them are resting in the shade under brushes, but there was one that was drinking from the watering hole directly in front of us.We then noticed just to our right, there were a couple of fresh zebra corpses(尸体)— it seemed as if the lions which were resting had killed them! We were unlucky not to have seen the actual kill, as our guide had mentioned that the zebra corpses were fresh and the kill had occurred within the last hour.

Our final big sighting was one that none of us were expecting to see, even our guide! We pulled over to where there was a large gathering of cars, with a sleeping leopard(美洲豹)there! We took photos happily and excitedly and observed its surprising body before returning to our hotel as it was getting late.

So, I hope you enjoyed my description of Tarangire, and that I have inspired you to add this amazing park to your very own Tanzania travel route.
