The search for a Malaysia Airlines passenger jet expanded this week. The airplane, a Boeing 777, disappeared last Saturday on a flight from Kuala Lumpur to Beijing. It was carrying 239 people. At first, the search was along its expected flight path.

But by week's end, crews had expanded the search across parts of southern Asia for any evidence of Malaysian Airlines Flight 370.

With satellites and other technology available, how can a plane as large as the "Triple-7" just disappear? Air safety expert John McGraw says it is easier than you may think.

"People are under the impression that every airplane, even when it's flying across the ocean, is observed on some kind of radar scope, with a human being looking at that scope. And it's just not the case. Radars don't reach that far."

But John McGraw says there are also a lot of devices inside the Triple-7 that can help searchers follow its movement. Systems in the aircraft send altitude, weather conditions, position and speed to air traffic controllers. There are also at least three ways the pilots can communicate with controllers. Another tool is the flight data recorder or "black box." If the plane is downed in the ocean, the black box sends out a signal that can travel up to three kilometers away.

Many people remember when a French passenger jet disappeared five years ago. Air France Flight 447 went missing as it flew from Brazil to Paris. Its wreckage was eventually found in the Atlantic Ocean.

Air safety expert John McGraw remembers the National Transportation Safety Board taking action after the French jet went missing. He says US officials called for continuous download of an aircraft's flight data recorder information in case of emergencies.

"In the past they haven't been able to justify installing that kind of equipment, because it's expensive, and because there hadn't been that many accidents where it would have come into play. This will certainly provide some additional motivation and there may be calls to do that."

Malaysia Airlines Flight 370 was last seen on radar above Vietnam and Malaysia. Air traffic controllers in both countries say they did not receive any message that the plane may have been in trouble. On Tuesday, Malaysian media reported that the Malaysian military had noted the aircraft flying toward the country's west coast. That is far from where controllers lost contact with the plane.

The next day, China released satellite images showing three large objects floating in waters between Malaysia and Vietnam.

But China later said it could not confirm the objects belonged to the missing aircraft.

,OU!^lrPA]H6LimPtKSe

The Wall Street Journal reported that the plane could have stayed in the air for several hours past the time of its last confirmed location. The newspaper later said that the plane continued to send information about its engines and performance to satellites for five more hours. That suggests Flight 370 could have remained in the air or was on the ground somewhere.

Why the signals stopped is unclear.

内容解析

tny5x=tsfdlv[Rf

1.People are under the impression that every airplane, even when it's flying across the ocean, is observed on some kind of radar scope, with a human being looking at that scope.

6SQWfDzFS&-WG[i

同位语从句属于名词性从句,大多由从属连词that引导,常常跟在fact, idea, opinion, news, hope, belief等名词后面1JwrlUNIVWzFB~。同位语从句一般用来解释或说明这些名词的具体含义或内容,在逻辑上表现为同位关系XdHvH=GE]ps。例如:

eQ-LLo+!Bfdr&t[_2GP

They are familiar with the opinion that all matter consists of atoms.他们很熟悉这一观点,所有的物质都是由原子构成的9[8E[R]h_M^An

15WS[QuxGNnU

1、从先行词来看

hm^FfN|u~oh0

同位语从句与名词之间在逻辑上是"主语+be+表语"的关系[@.R]X%z9rvP&n-。该名词是需要做特殊说明的抽象名词Q45YI=vAdo3。例如:

abVZsV#5tUU

They were delighted at the news that their team had won.当听到他们的球队赢了的消息时,他们欣喜若狂ZpGP9Fm1j8zsy^;k9]zZ

8hru]LMdx8t15Y~s|[

2、从引导词来看

72i&t+Pynp03xqu

引导词that在同位语从句中是连词,只起连接作用,无具体词义,that不可省略;that在定语从句中是关系代词,它在从句中充当一定成分---主语或宾语,有具体词意,作宾语时还可以省略EDDA)+Nd|M_l0IuP^u(_。试比较:

h=uvsBZtGD0)A1wH2P

The factory(that)we visited yesterday is a chemical one.我们昨天参观的那家工厂是化工厂grPdMY63D2G|E;&yL.。(that在从句中作宾语,所以此句是宾语从句)

vJ,#&o_)WjjEA

The news that he will leave for Shanghai is true.他将要去上海的消息是真的d_QmA1_mv~ef;F。(that只起连接从句的作用,所以此句是同位语从句)

但是,在卫星和其他技术到位的情况下,波音777这种大型飞机为何会突然失踪呢?空中安全专家John McGraw表示,这比想象中更加容易b0i@c6]^g67

但是John McGraw表示,波音777飞机内也有很多设备可以帮助搜索人员追踪其活动b8Tu@]hNleSyn@。飞机内的设备可以向空中交通管制员传送海拔,天气状况,位置和速度信息h9NiY(+_wYtiL@O。飞行员还有至少三种方法可以跟管制员联系+VOoDGF8@UZh;HUfQnyu。另外一种工具是飞行数据记录器,或者叫做“黑匣子”,如果飞机坠入海洋,黑匣子可以向远至3千米的范围发送信号smJ7P@SywOs

“过去他们并未就安装这种设备作出合理解释,因为这种设备非常昂贵,因为没有那么多的空中事故让这种设备发挥作用*6dtG6XXiH!l。毫无疑问,这为航空公司提供了安装黑匣子的动机,或许人们也会呼吁这样做qNb,MB,*46IL!FD。”
