A.was travellingB.travelled
C.had been travellingD.was to travel

分析 記者報(bào)道說(shuō),當(dāng)他看見(jiàn)UFO的時(shí)候,它正在由東向西飛行.

解答 答案A.
B項(xiàng)"一般過(guò)去時(shí)"表示發(fā)生在過(guò)去的動(dòng)作;C項(xiàng)"過(guò)去完成進(jìn)行時(shí)"表示持續(xù)到過(guò)去某時(shí)的一個(gè)動(dòng)作;D項(xiàng)"過(guò)去將來(lái)時(shí)"表示從過(guò)去某時(shí)看來(lái)將要發(fā)生的動(dòng)作或存在狀態(tài);A項(xiàng)"過(guò)去進(jìn)行時(shí)"表示在過(guò)去某一時(shí)刻或某一段時(shí)間內(nèi)發(fā)生的動(dòng)作;根據(jù)題干中的"when he saw it"可知,在過(guò)去的某個(gè)時(shí)刻,即"我看見(jiàn)的時(shí)候",所發(fā)生的事情,在那個(gè)時(shí)刻UFO正在由東向西飛行,所以應(yīng)該用過(guò)去進(jìn)行時(shí),故選A.

點(diǎn)評(píng) 本題考查時(shí)態(tài)辨析.解答此類題目首先要讀懂句意,捕捉信息,理解情境,綜合運(yùn)用,靈活答題,結(jié)合具體的語(yǔ)境,選出正確的時(shí)態(tài).在平時(shí)學(xué)習(xí)的過(guò)程中,對(duì)每一種時(shí)態(tài)的用法要掌握到位.

8.In America,each of the states likes to promote itself with a slogan(口號(hào)).I currently live in Utah,where the slogan is"Life Elevated".It's a nod to outdoor entertainment in the high country,including  the ski industry.I previously lived in Colorado,a land with red dirt,
great mountains and golden plains.T he slogan there is"Colorful  Colorado".Years ago I lived in the"Peach State"of Georgia,and I grew up in New Mexico as a little boy,whose slogan is"Land of  Enchantment(魔力)".
We never seemed to get away from dust in New Mexico,so I  appreciate the story of a   newcomer to the Land of Enchantment who learned about dusty breezes.She was visiting an antique shop and the owner wiped down every item before showing it.The newcomer said,"
Everything gets dusty here pretty quickly,doesn't it?""That's not dust,honey,"the shop owner replied,"That's ENCHANTMENT.".
That made the problem more acceptable.That an escalator(自動(dòng)扶梯)broke.He posted a sign to warn customers.He chose not to use the traditional"Out  of Order"or"Do Not Use"warnings.Instead,his sign read,"This Escalator Is Temporarily a Stairway."He turned a minus into humor and made it a plus.
And in fact there are some things,like the weather,we can't change.All we can change is our ways that we think and feel about them.I believe one of the best techniques to do this is to find some humor in the situation.Finding something amusing or enjoyable of  difficulty,an irritation or a troublesome problem can be one of the most creative and effective things we can do.Sometimes the only sense you can make of a situation is a sense of humor.
64.The first paragraph is severed as a(n)C.
A.predication  
B.explanation    
C.introduction   
D.conclusion
65.How would the newcomer probably feel after hearing what the  shop owner said?D
A.Angry.
B.Curious.
C.Nervous.
D.Relaxed.
66.What's the purpose of the writer's writing the passage?A
A.To encourage people to find the funny side in their daily life.
B.To show the effects of using slogans to raise the position.
C.To explain the skills of turning a disadvantage into humor.
D.To tell the strange experience of a bargain in an antique shop.

In the same way,we can learn to trust our heart's desires and our sense to guide us,(64)A any beliefs that stand in the way of our ability to fully invest in ourselves.As we take out energy from limiting ideas about what is possible,we(65)C the resources that have the power to make our inner economy prosper.

11.Centuries ago,man discovered that removing moisture(潮濕)from food helps to store it,and that the easiest way to do this is to expose the food to sun and wind.In this way the North American Indians produce pemmican(dried meat ground into powder and made into cakes),the Scandinavians make stockfish and the Arabs dried dates.
All foods include water-cabbage and other leaf vegetables contains as much as 93% water,potatoes and other root vegetables 80%,lean meat 75% and fish,anything from 80% to 60%,depending on how fatty it is.If this water is removed,the activity of the bacteria(細(xì)菌)which cause food to go bad is checked.
Fruit is sun-dried in Asia Minor,Greece,Spain and other Mediterranean countries,and also in California,South Africa and Australia.Various methods are used,but in general,the fruit is spread out on trays in drying yards in the hot sun.
Nowadays most foods are dried mechanically.The method of such dehydration(脫水)is to put food in chambers through which hot air is blown at temperatures of about 110℃at entry to about 43℃at exit.This is the usual method for drying such things as vegetables,minced(切碎的)meat,and fish.
Dried foods take up less room and weigh less than the same food packed in cans or frozen,and they do not need to be stored in special conditions.For these reasons they are invaluable to the climbers,explorers and soldiers in battle,who have little storage space.They are also popular with housewives because it takes so little time to cook them.Usually it is just a case of replacing the dried-out moisture with boiling water.

32.According to the text,the open-air method of drying food.C
A.is the one most commonly used today
B.was invented by the American Indians
C.has been known for hundreds of years
D.tends to be unhealthy
33.Bacteria which cause food to go bad.D
A.cannot live in sunlight
B.a(chǎn)re killed by drying
C.a(chǎn)re in no way dependent on the water contained
D.have their activity greatly reduced by drying
34.Today vegetables are most commonly dried.B
A.on hot and sunny days     
B.in hot-air chambers
C.in the sun and wind            
D.using the open tray method
35.Housewives like dried foods because they.A
A.a(chǎn)re quick to prepare              
B.taste better than fresh foods
C.can be packed in a case           
D.look fresh when cooked.

8.I can't remember a winter being as cold as this in Pennsylvania,but I'm sure there were colder days.
    Even though the daylight hours are growing longer minute by minute,it's easy to find an excuse not to go out unless you absolutely must,but then again I often have to push myself to accomplish things.
    People I speak to have been in all kinds of nasty moods.They say they're"under the weather,"not feeling good about this time of year.
    As I stood outside with my two dogs yesterday,it was so cold that my nose and face felt frozen and my ears were stinging.
    Of course,that doesn't matter to Ricky and Lucy.They have a routine they must go through to find just the fighting spot no matter how cold or hot it is.
    So I wait.
    But this time it was different.As cold as it was,I suddenly was excited thinking about how wonderful this extreme cold really was.
    Then the sun broke through the clouds and memories of summer's extremely hot days flashed through my mind.I could remember standing in the heat of the afternoon,with sweat pouring down my brow and the hot,burning sun against my face.I reminded myself then and there that in the cold of the winter I would wish I had this heat.
    I was grateful for the extremes.Without the extremes in my life,I would never appreciate the days when things were just right.Without the extremes,life would be boring.
    It's being pushed to one of the extremes that makes us appreciate the middle more.Health challenges remind us that we need to pay more attention to how we live.Financial extremes remind us that when things go smoothly it's also time to save for raining days.
    I've come to the conclusion that all too often I find a reason not to be happy with where I am at that moment.
    Whether it's hot or cold,good health or bad,in the money or out of it,I always
want it to be different.
    I'm tired of being"Under the Weather!"

31.What is the author's attitude towards the extremes in life?A
    A.Grateful.   B.Critical.
    C.Negative.   D.Unconcerned.
32.That day the writer waited in the terrible cold becauseC.
    A.his dogs wanted to hunt
    B.he wanted to face the cold bravely
    C.his dogs had a routine
    D.he wanted to be different
33.The underlined word"nasty"(Paragraph 4)can be replaced byA.
    A.unpleasant                           B.violent         
    C.favorable                            D.unusual
34.At last the author drew a conclusion thatB.
    A.happiness cannot be gained by complaints
    B.things will be different whatever the situation is
    C.happiness will fail to come to you if you can find a reason
    D.he is disappointed with his present situation
35.What is the best title for this passage?C
    A.Follow the Routine                   B.Two Extremes in Life
    C.Changes should be Expected           D.Weather Information.
