Fighting the pirates(海盜)
Last week Chinese warships departed on a mission to protect commercial ships and crews from pirate attacks off Somalia(索馬里)．
The fleet(艦隊(duì))，which contains two missile destroyers and a large supply ship，is armed with special forces and helicopters.The mission also plans to share information with other countries working in the area，military officials said.
The operation is China’s first major naval mission abroad.The two missile destroyers Haikou and Wuhan are top-of-the-line Chinese navy ships.They sail at a speed of 30 knots(海里/小時(shí))．On board the destroyer，there are two helicopters，anti-aircraft missiles，anti-ship missiles and cannon torpedoes(魚雷)．The destroyers can direct fire at a target 10 kilometers away.
One major issue for the ships is how they will resupply so far from home.Officials said it will mostly depend on the supply ship，but China will also negotiate with other countries in the area to allow the ships to dock(停靠碼頭)and resupply.
“In light of the peculiarity of this operation，we have also dispatched(派遣)some special forces.These special forces will carry light weapons that correspond with the specific features and needs of this operation，” a Chinese military official said at a news conference last Tuesday.
Though the purpose of the mission is to protect Chinese ships and crews，China has called for stepped-up cooperation on anti-piracy efforts.China announced it was sending warships to the area after the UN Security Council(聯(lián)合國(guó)安理會(huì))authorized nations to conduct land and air attacks on pirate bases.
“During the escort(護(hù)航)operation，Chinese ships are ready and willing to strengthen information and intelligence sharing as well as conduct humanitarian rescue operations with ships of relevant countries according to the situation on the ground，” said Huang Xueping，spokesman of the Ministry of National Defense.
The plan is for a mission of three months，according to Chinese news media.Piracy has taken an increasing toll(損失)on international shipping，especially in the Gulf of Aden(亞丁灣)，one of the world’s busiest sea-lanes.Pirates have made an estimated $30 million hijacking(劫持)ships this year，seizing more than 40 ships off Somalia’s 3,000 km coastline.
The People’s Liberation Army Navy has primarily focused on defending China’s coastline and，until now，limited operations abroad to port calls，goodwill visits and exercises with other navies.
1．What is the main idea of the passage?
A．It’s a general introduction to the People’s Liberation Army Navy in China.
B．It mainly informs us of how serious the problem of piracy has become.
C．It mainly introduces to readers China’s first major naval mission abroad.
D．It mainly tells readers why China sent her warships to Somalia last week.
2．Which of the following is TRUE according to the passage?
A．This is the first time China has carried out major exercises with other navies.
B．The destroyers are so powerful that they can aim at a target 10 km away.
C．Besides some advanced arms，there are 3 helicopters on every destroyer.
D．According to the mission，the fleet will stay in Somalia for four months.
3．The Chinese warships off Somalia will do the following EXCEPT ________.
A．protecting Chinese commercial ships and crews
B．sharing information with other countries working in the area
C．conducting humanitarian rescue operations
D．helping Somali government to fight against violence
4．What can we conclude from the passage?
A．The mission has been authorized by the UN Security Council.
B．The Gulf of Aden is the busiest sea-lane in the world.
C．The special forces on the destroyer will carry heavy weapons.
D．It’s estimated that pirates off Somalia seized 50 vessels this year.
5．How many ways are mentioned to solve the issue of resupply for the Chinese ships?
A．One.
B．Two.
C．Three.
D．Four.

7．解析：考查常識(shí)。結(jié)合全文及歷史知識(shí)可知，此處指托馬斯·杰斐遜從法國(guó)人手里購買路易斯安那地區(qū)的做法是否正確，故答案選C。
