7．As we all know，it is usually cold in this place in January，but it _____ be warm sometimes．（　�。�
A．mustB．canC．shouldD．would

分析 眾所周知，這個地方一月份通常冷，但是有時也會暖和．

解答 答案是B．本題考查表示推測的情態(tài)動詞的用法．情態(tài)動詞must表示推測只能出現(xiàn)在肯定句中，表示有客觀依據(jù)的推測"準是，一定是"．can表示推測往往出現(xiàn)在否定句或疑問句中；在肯定句中出現(xiàn)時表示"客觀上、理論上的可能性"，常常暗示可能性很小，與一般情況不相符．should表示推測時往往表示"按照常理常規(guī)的推測"，表示"按照道理應(yīng)該…"；would表示推測時表示有充分理由的推測；本題中由上文的"usually cold"，判斷"be warm"與一般情況不符，只是客觀上的可能性，所以答案是B．

點評 要在正確理解情態(tài)動詞的基本含義的基礎(chǔ)上，整體理解語境中的情感態(tài)度，做出合理的判斷．

18．Pilling a cat can be a'terrible"experience．Cats don't want something pushed down their throats，and they'll fight with all their strength to prevent it．In fact，it's amazing how powerful their small bodies can be．
The easiest way of pilling a cat is to press the pill into powder．Then mix the powder with a small amount of wet food．If your cat usually eats dry food，she will probably view the wet food as a treat and eat it up．
If your cat won't eat the wet food that contains the pill or if she is too ill to eat，you can get a"pill gun"．There are some basic instructions．Getting your cat's mouth to open is going to be the most difficult part．First，be sure the pill is in a handy place．Then you can put your cat on a bookshelf with her bottom in a corner or you can put her on your lap firmly tied．Have your cat facing to the right if you're right-handed．With your left hand，hold your cat at the cheekbones，putting your palm （手掌） at the top of her head．Keeping your finger off the trigger （扳機），with your right hand，Insert the pill gun until the pill is positioned over the tongue and open throat Be sure to give your cat a treat directly after giving the pill．
If you don't feel comfortable using a pill gun，you can try giving the pill by hand．Push your cat's head backwards just far enough so that her nose is pointing towards the ceiling．At this point，most cats will slightly open their mouths．With the little finger or ring finger of the hand holding the pill，open the bottom jaw a little more．You may need to hold her top jaw with your other hand while doing this．Aim straight and lightly throw the pill or drop it．Most cats will then swallow the pill．

72．Pilling a cat can be a terrible experience because catsC．

19．Just before midnight，six University of Cincinnati students were watching TV in an on-campus apartment when three men burst through the door．While one of the intruders pointed a gun at the group，the other two scooped up $4，400 worth of laptops，cell phones，video games and cash．Once they had what they wanted，the trio fled into the night．
Furious，the students chased down and tackled one of the burglars--the one with the gun．In the struggle，it went off，and a bullet grazed a student's leg．His friends piled on the gunman and held him until police showed up．
By the next day，the injured young man was back in his apartment，and the suspect was in jail，charged with burglary，felonious assault and receiving stolen property．But how did the men manage to storm into an on-campus residence that November night in the first place？Simple：Students told police the building's main doors hadn't latched properly for days．
As parents confront ballooning college costs and shrinking acceptance rates，they are finding themselves with an even bigger，more basic problem：Which campuses are safe？Colleges seem like idyllic and secure places，and for the most part，they are．But ivy-covered walls can't keep out every bad element．This country's 6，000 colleges and universities report some 40，000 burglaries，3，700 forcible sex offenses，7，000 aggravated assaults and 48 murders a year．Other hazards--fires，binge-drinking，mental-health problems--are also on the rise．
Of course，that's not what parents and students see on America's serene campuses．There's a false sense of security，says Harry Nolan，a safety consultant in New York City．"Students see guards patrolling at night or a video camera monitoring the dorm entrance and think，Nothing bad can happen to me，"he explains．"People don't know that safety controls are often very lax．"
65．What did the students do after the burglars fled into the night？B
A．They stood there in surprise．
B．They ran after the burglars at once．
C．They waited for the police．
D．They phoned their teacher．
66．What does the underlined word"latched"in the third paragraph probably mean？C
A．watched      B．fixed                C．locked           D．kept
67．What worries parents most except ballooning college costs and shrinking acceptance rates？B
A．Their children's grades in the universities or colleges．
B．Their children's safety in the universities or colleges．
C．Their children's behavior in the universities or colleges．
D．Their children's relationship with classmates in the universities or colleges．
