Once the emotions were classified．a DVD seemed the most efficient way to display them．In Mind Reading，each expressions is acted out-six times，by six different actors-in three seconds．

_______(49)．The explanation for this is simple：we may find it difficult to describe emotions using words，but we instantly recognize one when we see it on someone's face．\，\，who directed the DVD．

BUt though we find it difficult to describe many emotions，we instantly recognize one when we see one．\，there was a split second when it was absolutely there．It was really clear when they'd got it，\，who directed the DVD． \，they were not told which facial muscle they should move．\example，when someone feels contempt，you can't say for certain that their eyebrows always go down．

Someone who has tried to establish such rules is the American Professor Paul Ekman．who has built a database of how the face moves for every emotion．The face can make 43 distinct muscle movements called\．These can be combined into more than 10．000 visible facial shapes．Ekman has written out a paper of facial muscular movements to represent each emotion．

A．We thought of trying to describe each emotion but it would have been almost impossible tomake clear rules for this

B．These particular muscles aye difficult to control，and few people can do it． C．Research has also been done to find out which areas of the brain read the emotional expressions．

D．They decided that it was a mental state that could be preceded by\looks\．

E．He said that the expression of theses feelings aye universal and recognizable by anyone，from any culture．

F．Any other method of showing all the 412 emotions，such as words，would have been far less efiective．

第6部分：完形填空(第51～65题，每题1分，共15分)

下面的短文有15处空白，请根据短文内容为每处空白确定1个最佳选项。 Obtaining Drinking Water from Air Humidity

Not a plant to be seen，the desert ground is too dry．But the air contains water，and research scientists have found a_________(51)of obtaining drinking water from air humidity．The system isbased completely on renewable energy and is therefore autonomous．

Cracks permeate the dried-out desert ground and the landscape bears testimony to the lack of water．But even here，where there are no lakes，rivers or groundwater，considerable quantities of water are stored in the air．In the Negev desert in Israel，for example，annual average relative air hu-midity is 64 percent-in every cubic meter of air there aye 11．5 milliliters of water．

German research scientists have found a way of converting this air humidity autonomously intodrinkable water．\on renewable energy sources_______(52)thermal solar collectors and photovoltaic ceils，_________(53)makes this methodcompletely energy-autonomous．It

will_______(54)function in regions where there is no electricalinfrastructure．\Siegfried Egner，head of the research team．The principle of the_______ (55)is as follows：hygroscopic brine-saline solution which absorbs moistureruns down a

tower-shapedunit and absorbs water from the air．It is then sucked_________(56)a tank a few meters off the ground in which a vacuum prevails．Energy from solar

collectors_________(57)up the brine，whichis diluted by the water it has________(58).

Because of the vacuum，the boiling point of the liquid is lower thaa it would be under_____ (59)atmospheric pressure．This effect is known from the mountains：as the atmospheric pressure there is lower than in the valley，water boils at temperatures distinctly below 100~C．The evaporated， non-saline water is condensed and runs down through a completely filled tube in a controlled manner．The gravity of this water column_________(60)produces the vacuum and so a vacuum pump is not needed.The reconcentrated brine________(61)down the tower surface again to absorb moisture from the air．

\．Single-person units and plants supplying water to entire hotels are conceivable，\．Prototypes have been built for______

(63)system components-air moisture absorption and vacuum evaporation-and the research scientistshave Mready________(64)their interplay on a laboratory scale．In a further________(65)the researchers intend to develop a demonstration facility．
