17．___ is left over may be put into the refrigerator，____ it will keep for two or three weeks．（　　）

	A．	Whoever； when		B．	Whenever； which
	C．	Whatever； where		D．	Whichever； while

分析无论什么剩下的东西都应该被放进冰箱，它将会保鲜两到三周．

解答答案：C．根据may be put into the refrigerator可知前面是主语从句，再结合句意，无论什么剩下的东西，选whatever，后面是个定语从句，先行词refrigerator，在定语从句中作地点状语，因此第二空填where，故选C．

点评本题考查疑问词加ever 的主语从句及定语从句，在熟知疑问词加ever 无论…，基本上，很容易选出此题答案．

7．Look at the keyboard of any standard typewriter or computer．"Q"，"W"，"E"，"R"，"T"and"Y"are the first six letters．Who decided on this arrangement of the letters？And why？
People tried for centuries to invent the typewriter．In 1714in England，Henry Mill filed a patent for a machine called An Artificial Machine or Method for the Impressing or Transcribing of Letters，Singly or Progressively one after another，as in Writing．With this machine，whatever writing can be shown on paper or parchment，so neat and exact as not to be distinguished from print．That machine probably didn't sell because no one could remember its name!
The first practical typewriter was patented in the United States in 1868by Christopher Latham Sholes．His machine was known as the type-writer．It had a movable carriage，a lever for turning paper from line to line，and a keyboard on which the letters were arranged in alphabetical order．
But Sholes had a problem．On his first model，his"ABC"key arrangement caused the keys to jam when the typist worked quickly．Sholes didn't know how to keep the keys from sticking，so his solution was to keep the typist from typing too fast．Sholes asked his brother-in-law to rearrange the keyboard so that the commonest letters were not so close together and the type bars would come from opposite directions．Thus they would not clash together and jam the machine．The new arrangement was the QWERTY arrangement typists use today．Of course，Sholes claimed that the new arrangement was scientific and would add speed and efficiency．The only efficiency it added was to slow the typist down，since almost any word in the English language required the typist's fingers to cover more distance on the keyboard．
The advantages of the typewriter outweighed the disadvantages of the keyboard．Typists memorized the crazy letter arrangement，and the typewriter became a huge success．By the time typists had memorized the new arrangement of letters and built their speed，typewriter technology had improved，and the keys didn't stick as badly as they had at first．

41．Who invented the first practical typewriter？C

A．arrange the letters in alphabetical order
B．solve the problem of the keys jamming
C．cause the keys to jam when the typist worked quickly
D．compete with"ABC"key arrangement
44．We can infer that the QWERTY arrangement of the keyboardA．

C．is easy for typists to memorize

45．Which of the following can be the best title of the passage？B

5．Modern humans have a hard time controlling their desire to eat．Often you eat not because you are hungry，but because you are affected by many other things．How much you eat is strongly affected by how much those around you eat．People eating alone eat least．People eating with one other person eat 35 percent more than they do at home．People dining in a party of four eat 75percent more．Eating with overweight friends？You'll eat more．Is your waitress overweight？
You'll eat more．Wide variety of food？You'll eat more．
   Plates can decide how sweet dessert tastes．If people ate it off a paper plate，they'd say，"This is good．"If they ate it off a fancy silver plate，they would say，"This is the greatest cake I've eaten in my entire life．"
    Your knowledge about what makes food good or bad also affects how much you eat．You tend to eat more when you think the food is good，and less when you think it is bad．So Grandma's cookies always taste better than other cookies．"Good food"even has a"health halo（光环） effect"．If we're eating something healthy，we feel that everything in that meal is healthy．Due to this，people often believe that a cheese cake with a salad has fewer calories （卡路里） than the cheese cake alone．That's perhaps also why eating organic （有机的） food might turn you into an annoying guy．Your brain may use anything that makes you feel good about your own morality to excuse your immoral behaviour．
    Food and hunger affect your judgment too．Hungry judges give more serious sentences．Kids who don't eat breakfast behave worse than kids who eat their breakfast．People who have low blood sugar are more likely than the average person to have trouble concentrating and controlling their unpleasant emotions．
28．What is mentioned as a cause of overeating？D
A．Suffering from great loneliness．
B．Being served by a helpful waitress．
C．Being treated to high quality food．
D．Eating with many friends．
29．According to the passage，an annoying person may be one whoA．
A．finds any excuse for eating more
B．is crazy about the quality of plates
C．competes with others in making cookies
D．teaches people to stick to morality
30．According to the passage，people are more likely to make a bad judgment whenC．
A．they don't feel hungry
B．they aren't overweight
C．they have low blood sugar
D．they know little about food
31．What would be the best title for the passage？B
A．When Can't We Go on a Diet？
B．Why Affects Eating？
C．How to Make Good Food
D．Where to Find Safe Food．
