iy China's first aircraft carrier began sea trials Wednesday,marking a milestone in the country's rapid military modernization and longterm strategy to challenge U. S. military su?premacy in Asia and project power far beyond Chinese shores.

The 300-meter-long carrier,based on an empty hull bought from Ukraine,sounded its horn three times as it ploughed through the morning fog around Dalian and headed out to sea,accord?ing to one witness writing on the military microblog of the staterun Xinhua News Agency.

The carrier,featuring its original skijump runway to launch fighters and a new engine and radar equipment,has been undergoing refurbishment (重新装备) for the last decade in the north?eastern port.

Xinhua said the sea trials " would not take a long time”,without giving details of the exact duration or say what sort of tests would be carried out. " After returning from the sea trial,the aircraft carrier will continue refit and test work," it said.

The provincial Maritime Safety Authority said on its web site that all vessels will be barred (被禁止的) from entering a small section of sea off Dalian until 6 p. m. local time Aug. 14.

The launch had long been expected as final preparations of the vessel―which has yet to be named by China ― were visible from many points around Dalian and had been regularly photographed and documented online by amateur enthusiasts.

A Chinese company purchased the empty hull of a carrier called the Varyag from Ukraine in 1998 on the understanding that it would be used as a floating casino,but it was later towed (4& 曳) to Dalian via the Black Sea,the Mediterranean and the Straits of Malacca.

China officially acknowledged only last month that it was refurbishing the vessel,and tried to ease regional concerns by saying it would be used for "research,experiments and training" and would take a long time to become fully operational.

China is the only one of the five permanent members of the U. N.Security Council,which includes theU. S.,Britain,FranceandRussia,without an operational carrier.IndiaandThai?landhave a carrier each,whileJapanhas one that carries helicopters.

"It's warm,it's fun and it won't break the bank (耗尽资源) "goes the ad for a wellknown package holiday group. The top billing given to temperature in the slogan illustrates just how im?portant climate is to holidaymakers. It's one of the first things you notice when you step off the plane―part of the " sense of place" which academics talk about.

Australia is a big country,stretching from the tropics to the roaring forties,and it has a correspondingly wide range of climates. There's something to suit everyone!Scubadivers like the warm waters off the tropical Queensland coast;sunlovers feel at home in central Australia's hot,dry climate. The cool temperate climate of the Australian Alps in the southeast of the conti?nent attracts skiers in winter and walkers in summer.

What is the best time of year to visitAustralia? It depends on what part of the country you will be visiting and what you would like to do. If you can stay for several months,you can plan your trip to catch the best weather everywhere.

Australia can be divided into six main climatic regions or zones on the basis of air tempera?ture and humidity. Our map shows where each region is. A description of each region's climate is given below,from the viewpoint of someone accustomed to a temperate climate. People from tropical climates will tolerate the heat better than indicated in the zone descriptions,but will feel less comfortable in the cooler parts of the country. The climate zones are:

Some plants get so hungry they eat flies,spiders,and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact,they're found on every continent except Antarctica.

You've probably seen a Venus' flytrap (捕蝾草) .It's often sold in museum gift stores,de?partment stores,and even supermarkets. A small plant,it grows 6 to 8 inches tall in a contain?er. At the end of its stalks (茎) are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger (触发) hairs. When an insect lands on them,the trap suddenly shut. Over the course of a week or so,the plant feeds on its catch.

The Venus' flytrap is just one of more than 500 species of meateating plants,says Barry Meyers-Rice,the editor of the International Carnivorous Plant Society's Newsletter. Note: Despite any sciencefiction stories (科幻小说) you might have read,no meateating plant does any danger to humans.

Dr. Meyers-Rice says a plant is meateating,only if it does all four of the following: " at?tract,kill,digest,and absorb" some form of insects,including flies,butterflies,and moths. Meateating plants look and act like other green plants―well,most of the time.

All green plants make sugar through a process called photosynthesis (光合作用) .Plants use the sugar to make food. What makes " meateating" plants different is their bugcatching leaves. They need insects for one reason;nitrogen (氮) .Nitrogen is a nutrient that they can't obtain by any other way. Why?

Almost all green plants on our planet get nitrogen from the soil. " Meateating" plants can't. They live in places where nutrients are hard or almost impossible to get from the soil be?cause of its acidity (酸度) .So they've come to rely on getting nitrogen from insects and small animals. In fact,nutrientrich soil is poisonous to "meateating" plants. Never fertilize (施肥) them!But don't worry,either,if they never seem to catch any insects. They can survive,but they'll grow very slowly.

(   ) 1. What is a Venus flytrap?

   A. It is a small plant which grows in a container.

   B. It grows 6-8 inches tall.

   C. It can attract,kill,digest and absorb some form of insects.

   D. It is a kind of plant which gets hungry easily.

(   ) 2. What can we learn from the passage?

   A. It is the bugcatch leaves make Venus flytrap different from other plants.

   B. All green plants get nitrogen from the soil.

   C. " Meateating" plants are found on every continent.

   D. Some "meateating" plants in the world do danger to humans.

(   ) 3. Why does the writer say "Never fertilize ' meateating' plants?"

   A. Though growing slowly,they don't need nitrogen.

   B. Probably because the source of nitrogen is adequate.

   C. Simply because the nutrientrich soil will do harm to them.

   D. Perhaps they can get fertilize by themselves.

(   ) 4. Which of the following might be the best title for the text?

   A. Meateating Plant Does No Danger to Humans

   B. Let These Plants Swat (重击) the Bugs for You

   C. No Need to Fertilize Meateating Plants

   D. No Insects,No "Meateating" Plants
