A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.
Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

Death Valley is one of the most famous deserts in the United States, covering a wide area with its alkali sand. Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280 feet below sea level and the lowest point in the United States.
Long ago the Panamint Indians called this place "Tomesha"-- the land of fire. Death Valley's present name dates back to 1849, when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has been declared a National Monument and is crossed by several well-marked roads where good services can be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this place.
Here nature created a lot of surprising, almost like the sights on the moon, ever-changing as the frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and colorful parts of Death Valley is the Devil's Golf Course, where it seems hard for one to tell reality from dreams. Sand sculptures stand on a frightening ground, as evening shadows move and lengthen.

A. an Indian name B. the death of the miners

Tanzania Tarangire is a national park 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 it to see what it was like.
One of the first sightings upon entering the park I found was a huge group of elephants. Our guide told us Tarangire was probably the best place in Tanzania to find large groups of elephants. We continued to watch the elephants as they stood under trees and scratched(搔)themselves against the trees to hit the spot of an itch(痒).
To the right of the elephant group, we noticed a big tree. Our guide informed us that this was a baobab tree and 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 there were lions all around us. Most of them were resting in the shade under bushes, but there was one that was drinking from the watering hole directly in front of us. We then noticed there were a couple of fresh zebra corpses(尸体)—it seemed as if the resting lions had killed them!
Our final big sighting was one that none of us were expecting to see!We pulled over to where there was a large gathering of cars, with a sleeping leopard 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've inspired you to add this amazing park to your very own Tanzania travel plan.
