The human nose is an underestimated tool. Humans are often thought to be1___ smellers compared with animals, but this is largely because, unlike animals, we stand upright. This means that our noses are 2 to detecting those smells which float through the air, 3 the majority of smells which stick to surfaces. In fact though, we are extremely sensitive to smells, even if we do not generally realize it. Our noses are capable of 4 human smells even when these are 5 to far below one part in one million.6 , some people find that they can smell one type of flower but not another, while others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate7 smell receptors in the nose. These receptors are the cells which sense smells and send8 to the brain. However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when9 to it often enough.The 10 for insensitivity to smell seems to be that brain finds it 11 to keep all smell receptors working all the time but can 12 new receptors if necessary. This may also explain why we are not usually sensitive to our own smells we simply do not need to be. We are not 13 of the usual smell of our own house but we 14 new smells when we visit someone else's. The brain finds it best to keep smell receptors _ 15 for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.1. A. sensitive B. outstanding C. insensitive D. awkward2. A. limited B. committed C. devoted D. conducted3. A. catching B. ignoring C. missing D. tracking4.

The map was so detailed that the operation’s planners could build a copy of the building for rehearsals (演习).“The outer features of the building were studied intensively,” John Brennan, the White House’s deputy national security adviser for homeland security and anti-terrorism, told journalists today.The Pentagon (五角大楼) used a group of military satellites for imagery in a variety of wavelengths, but it also picks up pictures from commercial satellite companies such as GeoEye and DigitalGlobe — the same companies that provide mapping data for websites such as Google Earth. A series of satellite pictures can be used to trace the history of the building site from an empty lot in 2001, to a newly built complex in 2005, to an even more built-out neighborhood this January.Tracking down the precise location of bin Laden’s base on satellite imagery occupied the attention of geo-geeks for hours, until the CIA provided the solution to the puzzle. Postings on the Google Earth blog trace every step of the hunt.Once the decision was made to go ahead with the surprise attack, another set of satellites came into play: A space-based military satellite system that provides a secure communication channel between the warfighters in the field and the experts directing the operation from far off. Even President Obama could monitor the action in real time from the White House Situation Room, just as CIA Director Leon Panetta could from the spy agency’s headquarters.The main satellites involved here are the Defense Satellite Communications System, or DSCS-III and the Milstar system. Milstar has more capability for secure communications, but it doesn’t offer as much signal ban dwidth as DSCS-III. The satellite system links up with communication terminals that are installed at bases on the ground, placed on ships stationed offshore, or even carried around by the helicopter fighters. The Navy SEALs who took on the “get bin Laden” mission typically wear helmet-cameras that can send a stream of coded video halfway around the world.These high-tech surveillance (监视) and communication tools finally provided the U.S. military with a high-tech edge over bin Laden and his supporters, who had to go low-tech to avoid detection. But it was just that very low-techiness that gave away to the CIA: The fact that amillion-dollar complex had no phone lines or Internet links led analysts to suspect that they had the right target in their sights.书面表达请细读以下这封信,根据信中提到的问题写一封回函。
