16．Time is in the year 2095．It is reported that a comet（彗星） is rushing towards the Earth．Most of it will miss our earth，but two pieces will probably hit the southern half of our planet
On 15 July，a piece about four kilometers wide enters the Earth's atmosphere with a massive explosion（爆炸）．About half of the piece is destroyed，but the remaining part hits the South Atlantic at 200 times the speed of sound．A hole is made in the sea bed．Huge waves spread outwards from the hole．The wall of water，a kilometer high，rushes towards southern Africa at 800 kilometers an hour．Cities on the African coast are totally destroyed and millions of people are drowned．
Before the waves arrive in South America，the second piece of the comet hits Argentina．Earthquakes and volcanoes（火山爆发） are set off in the Andes Mountains．The shock waves move north into California and all around the Pacific Ocean．The cities of Los Angeles，San Francisco and Tokyo are com pletely destroyed by earthquakes．Millions of people in the southern half of the earth are already dead，but the north won't escape for long．Because of the explosions，the sun is hidden by clouds of dust，temperatures around the world fall to almost zero．Crops are destroyed．The sun won't be seen again for many years．Wars break out as countries fight for food．A year later，no more than 10 million people remain alive．
Could it really happen？In fact，it has already happened more than once in the history of the Earth．The dinosaurs were on the Earth for over 160 million years．Then 65 million years ago they suddenly disappeared．Many scientists believe that the Earth was hit by a piece of object in space．The dinosaurs couldn't live through the cold climate that followed and they died out．Will we meet the same end？

13．The panda is one of the animals most in danger．There are about 1，000pandas living in nature reserves today．Zoos and research centers look after about 160pandas．Scientists are studying how they live and more baby pandas are born in the zoos．
Pandas live in the forests and mountains of Southwest China．They mainly live on bamboo，and each panda needs to eat a lot of bamboo every day．The area of bamboo is becoming smaller for many different reasons，so pandas have less and less land to live on．Pandas don't have many babies，and baby pandas often die，The situation is becoming very serious．
Our government is working hard to save pandas．There are more than 30nature reserves to protect pandas but these are not enough．The government has made a new plan to help pandas．The nature reserves will be bigger and the bamboo will grow better．Then the pandas will have enough food to eat and enough places to live in．Pandas born in the zoos may go back to live in the nature reserves．
Most people love pandas．The panda is one of the best-known animals in the world．It is the symbol for the World Wide Fund For Nature．The WWF works to protect all animals in danger，so the panda has become the symbol of all animals in danger．There is still a long way to go to save the panda．Think of other animals in danger such as tigers，whales，turtles and elephants-we need to save the panda，and we need to save them，too．
