【題目】【原創(chuàng)】The latest Chinese "god song" (an Internet term to describe pop songs that spread virally(病毒性地) through Internet) is still stirring fierce 【1】d______ between those who view it as a milestone for Chinese pop music going global and those who regard it as bad for China's image.

Last week, Little Apple, written and【2】_____(表演) by the Chopsticks Brothers, won the AMA International Song Award and the duo performed the song at the 2014 American Music Awards in Los Angeles. Another Chinese pop 【3】 ______, Zhang Jie, won the International Artist Award.

Although the song was generally dismissed by music professionals who criticized it as musical "junk food", Little Apple's popularity nationally paved the way for promoting the duo internationally.

【題目】When 18thcentury scientists first came across Australia’s platypus (鴨嘴獸)，they thought it was a trick.It is not surprising that the platypus made people confused.This funnylooking animal has feet and is a kind of warmblooded mammal(哺乳動(dòng)物)．

While other mammals usually keep their blood at around 37 degrees，the platypus has a lower body temperature of 32 degrees.As to its appearance，the platypus’ mouth is not really like the duck’s; its mouth actually looks a bit softer.The platypus closes its eyes when swimming instead of watching its hunters.It uses its mouth to pick up outside information made by the creatures underwater.

Strangest of all，the platypus is a mammal that can lay eggs.And there is only one other kind of mammal that can lay eggs，the echidna(針鼴鼠) of Australia.Both the platypus and the echidna lay soft shelled eggs，and both feed their young with their own milk that comes out of their skin.These animals also walk in a way that is similar to crocodiles (鱷魚(yú))，with legs on the sides of their bodies rather than under them.

Though pretty in a special way，the platypus is actually one of the few mammals that are poisonous.A male platypus has knifelike bones on its back legs which have enough poison to kill a dog.

The platypus has the honor of being one of the oldest mammals in the world.Until the early 20thcentury，it was hunted for its fur，but it is now protected.Although the platypus is easily influenced by pollution，it is not under any immediate threat.

【1】What can we learn about he platypus?

A．It has a lower body temperature than other mammals.
