题目:

根据下面材料,依次概括“嫦娥三号”探测器落月全过程的四个关键步骤,每一步骤的概括不超过5个字。(4分)

据介绍,“嫦娥三号”探测器由月球车和着陆器组成,根据落月探测时可能遇到的状况,探测器进行了多方面的充分准备。为了克服能源限制特别是推进剂限制,“嫦娥三号”设计了环月圆轨道飞行方案,运行一段时间后开始进行变轨。考虑到探测器降落地点和月球表面存在不可知性,“嫦娥三号”将采取软着陆的措施。当探测器接近月球时,将使用新研制的一种变推力发动机来刹车,以确保制动效果。安全降落后,月球车要从着陆器上分离、释放、解锁,转移到架舱(梯子)上来,再降落到月面。

LONDON---A British judge on Thursday sentenced a businessman who sold fake(假冒的)bomb detectors(探测器)to 10 years in prison, saying the man hadn’t cared about potentially deadly consequences.

It is believed that James McCormick got about $ 77.8 million from the sales of his detectors---which were based on a kind of golf ball finder---to countries including Iraq, Belgium and Saudi Arabia.

McCormick, 57, was convicted(判罪)of cheats last month and sentenced Thursday at the Old Bailey court in London.

“Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people,” Judge Richard Hone told McCormick. “You have neither regret, nor shame, nor any sense of guilt.”

The detectors, sold for up to $ 42, 000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they “lacked any grounding in science” and were of no use.

McCormick had told the court that he sold his detectors to the police in Kenya, the prison service in Hong Kong, the army in Egypt and the border control in Thailand.

“I never had any bad results from customers,” he said.
