May 26, 2011—Cities and provinces along the Yangtze River in central China are struggling with the country’s worst drought in more than 50 years. Resource analysts say, the drought highlights(突出，强调) not only the impact of climate change, but also China’s long-lasting problem of lack of water and how it must balance that with the country’s enormous demand for energy and economic growth.

     Poyang Lake is the largest freshwater lake in China and is just one example of how serious the drought has become. The lake, which is located in Jiangxi Province along the Yangtze River, has become smaller to less than half its usual size, and the lack of water has had a major impact on nearby fishing and farming.

    With water levels so low, stretches of the Yangtze River have become impassable for cargo vessels(货轮), destroying supply chains that fuel factories along the river, and transport manufactured products and agricultural goods. Analysts say the river is used to transport about 100 billion tons of goods each year.

    There is a lot of hydropower(水力发电)in the Yangtze River basin. For example, the Three Gorges Dam and power production from those sources have gone down by 20 percent according to some estimates(估算值) as a result of this drought. Any company that relies on that power is feeling the impact. Some are even being forced to ration their power use, he said.

    According to Chinese state media, the drought has affected more than one million hectares of farmland in seven provinces in central China. Local government officials reportedly have fired more than 4, 000 cloud-seeding rockets into the sky to try to bring rain to dry regions along the river. The forecast, however, continues to be for little rain until at least next month.

You may have seen a lot of frogs, but if you haven't, you must have heard about frogs. However, have you heard about a frog that can kill a person?

       These small brightly colored amphibians (两栖动物) live in the tropical  rain forests of Central and South America. They are best known for their ability to kill persons even though they are no more than 2 inches long. If we touch their poisonous skin without proper protection (such as gloves), we may die! For animals of this size that can be so deadly, they are certainly one of the world's most poisonous animals! Who are they? They are poison arrow frogs or, simply, poison frogs.

        Poison frogs acquired their name from the Indians. The Indians catch and kill many of these frogs before hanging them upside down over a campfire. As the frogs get hot, the poison drips out of their skin. The Indians collect the poisonous liquid in a bottle and dip(蘸) the tips of their arrows into the bottle. Once the tips are dried, they are ready to be used for their arrows for hunting.

       There are about 170 different types of poison arrow frogs in the world. Though most species have bright markings, either in stripes or patches, on their black bodies, some just wear noticeable single-colored coats. Their shocking skin colors-usually in yellow, red, green, blue or orange-serve as a warning sign to other animals. The sign simply says,” Stay away or pay with your life!” They certainly do not bluff.

1.We can infer that the Indians may kill poison frogs in order to______.

 A. treat diseases                                        B. avoid being bitten

C. hunt animals                                  D. eat their meat

2.According to the passage,  poison frogs______.

A can grow to several meters long                    B. like to change colors on the back

C. have bright-colored skin or markings             D. are on the edge of dying out

3.Which of the following best explains the last sentence of the passage?

A. Poison frogs don't want to kill others.

B. Poison frogs do not just scare others.

C. Poison frogs want to stop others from coming near.

D. Poison frogs just pretend to be dangerous animals.
