7.So quickly_______is a possibility today may be a reality tomorrow.(  )
A.are science and technology advancing that
B.science and technology advancing are that
C.are science and technology advancing that what
D.science and technology are advancing what that

分析 科学技术发展如此之快以至于今天有可能的事情明天就可能成为现实.

解答 答案:C.
在"so+形容词/副词+…that…"句型中"so+形容词/副词"置于句首,主句主谓部分需部分倒装,故排除B、D两项;that引导结果状语从句,该状语从句又含一主语从句,即"________is a possibility today",该从句缺少主语,且表示"事物",故用what引导.综上所述答案为C项.

点评 对于倒装结构的用法要多总结,结合具体的句子语境进行认真分析,综合考虑后作出最后的判断.

10.A few months ago the potato was considered an enemy in the obesity battle but a new study shows the food isn't that bad after all.
In June,researchers from Harvard University found that eating some of the potato[]every day,whether mashed(被磨碎),deep fried or baked,caused more weight gain than an extra can of drink or red or some kind of meat.The conclusion was that it happened because potatoes were always cooked-----making it easier for the body to change the starch(淀粉) which would increase the blood sugar levels.The body then had to work extra hard to get levels down but falling blood sugar made people hungry,which led to eating more food.
But a University of Otago study showed today brought some good news for spud lovers.It found it was hard to tell the glycemic index(GI)(血糖指数) level of mixed meals for persons."In general,different foods are tested for GI and it is less usual to test the GI for a whole meal,"one of the study's authors,Hayley Dodd,said."However,in this study,the GIs of three meals were tested.The meals all contained chicken,peas,carrots and mutton together with a lot of food including potato,white rice or spaghetti."
It found the GI for each meal lower than thought; researchers had expected the potato meal would have a GI of 65,but it came in at 53,which was low."Although potato is high-GI food into their meals-----our work suggests that having a small amount of potato with a meal isn't going to drive your blood sugar high.
The study involved 30healthy people aged 18-50.The research has been published in the October issue of the American.
8.The underlined word"spud"in the third paragraph may meanD.
A.chicken     
B.pea     
C.carrot     
D.potato
9.The potato will make people fat easily whenB.
A.it is eaten raw   
B.it is cooked   
C.it has blood sugar 
D.it is eaten[]with drinks
10.If a person has a low blood sugar,he willB.
A.feel angry quickly 
B.become hungry easily  
C.get thin soon   
D.eat food slowly
11.From the study of the University of Otago we can knowB.
A.people will get fatter and fatter if they eat potatoes

C.he glycemic index in the potatoes is very low
D.potatoes are the main enemy in the obesity battle.

There are also varieties developed to suit certain local conditions.One of the very best varieties for eating quality is Orleans Reinette,but you'll need a warm,sheltered place with perfect soil to grow it,so it's  a pipe dreamfor most apple lovers who fall in love with it.
At the apple events,you can also meet expert growers and discuss which ones will best suit your conditions,and because these are family affairs,children are well entertained with apple-themed fun and games.
Apple days are being held at all sorts of places with an interest in fruit,including stately gardens and commercial orchards(果园).If you want to have a real orchard experience,visit the National Collection at Brogdale,near Faversham in Kent.

2.Would you ever hug a stranger?There's actually a social activity of offering hugs to strangers in public places.It's known as the Free Hugs Campaign.The hugs are meant to be random(随机的) acts of kindness-selfless acts performed just to make others feel better.The person offering the hugs often makes a sign that reads"FREE HUGS",then holds it up in the street and waits for someone to ask for a hug.

The activity was started by Australian Juan Mann in 2004.Juan had been living in London for almost 10 years when he decided to return to Sydney after his girlfriend decided to leave him.On landing,he had nothing but his suitc ase.After about three months,an old friend invited him to a party.In an interview with WHO magazine,Juan said that while he was at the party,"…a completely random person I didn't know came up to me and gave me a hug.I felt like a king!It was the greatest thing that ever happened."Then,he had an idea.

Things really took off after a FREE HUGS video was uploaded to YouTube.While in Sydney,Juan met an American musician,Shimon Moore,who filmed Juan giving away free hugs and later used what he had shot to make a music video for the song All the Same by his band The Sick Puppies.The video was later uploaded to YouTube,where it has been viewed over 70 million times.
As a result of the video,the Free Hugs activity became international and then developed to China,Italy,America,Switzerland,Norway,India,Portugal and the UK.An International Free Hugs Day was set on the first Saturday following 30th June as this was the date of the first time that Juan ever offered free hugs in Sydney.
52.What is the purpose of the Free Hugs Campaign?To show kindness to others and make them feel better
53.What gave Juan Mann the idea of offering free hugs?A stranger's hug which cheered him up

12.To us,it seems so natural to put up an umbrella to keep the water off when it rains.But in fact the umbrella was not invented as protection against the rain.Its first use was as a shade against the sun.

Umbrellas have not changed much in style during all this time,though they have become much lighter in weight.It wasn't until the twentieth century that the umbrellas for women began to be made in all kinds of colors.

7.Why do Americans struggle with watching their weight,while the French,who consume rich food,continue to stay thin?Now a research by Cornell University suggests how life style and decisions about eating may affect weight.Researchers conclude that the French tend (易于) to stop eating when they feel full.However,Americans tend to stop when their plate is empty or their favorite TV show is over.
According to Dr.Joseph Mercola,a health expert,the French see eating as an important part of their life style.They enjoy food and therefore spend a fairly long time at the table,while Americans see eating as something to be squeezed (挤出) between the other daily activities.Mercola believes Americans lose the ability to sense when they are actually full.So they keep eating long after the French would have stopped.In addition,he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week.The French,instead,tend to shop daily,walking to small shops and farmers'markets where they have a choice of fresh fruits,vegetables,and eggs as well as high-quality meats for each meal.
After a visit to the United States,Mireille Guiliano,author of French Women Don't Get Fat,decided to write about the importance of knowing when to stop rather than suggesting how to avoid food.Today she continues to stay slim and rarely goes to the gym.
In spite of all these differences,evidence shows that recent life style changes may be affecting French eating habits.Today the rate of obesity-or extreme overweight-among adults is only 6%.However,as American fast food gains acceptance and the young reject (拒绝) older traditions,the obesity rate among French children has reached 17%-and is growing.

33.In what way are the French different from Americans according to Dr.Joseph Mercola?B
A.They go shopping at supermarkets more frequently.
B.They regard eating as a key part of their life style.
C.They squeeze eating between the other daily activities.
D.They usually eat too much canned and frozen food.
34.This text is mainly about the relationship betweenC.
A.children and adults          B.Americans and the French
C.life style and obesity      D.fast food and overweight
35.Where does this text probably come from?A
A.A health report         B.A book review
C.A TV interview    D.A food advertisement.

8.Swapping Houses for Vacation
When budgeting for a vacation,usually the most expensive part of the trip is the accommodations.The traditional way to take a vacation is to pack some bags,lock up the house,and travel to a new place to stay in a hotel.However,hotels are very expensive,and with rent or housing loan(贷款)due every month,it's difficult for most people to pay for yet another place to stay.(71)C  Luckily,there is a substitute called house swapping,and it's saving tourists a great deal of cash.
(72)D For example,if a couple from New York want to spend a week in Paris,they would place an ad offering to trade their New York apartment for one in Paris for a week.If a Parisian couple that want to vacation in New York read the advertisement,houses can be swapped,and both couples save hundreds,if not thousands,of dollars by avoiding big-city hotel fees.If all goes well,both couples can post positive reviews of the other's home online so that potential travelers can see that everything was fine.(73)G This builds a community of people who want to help each other out.
There are other advantages co house swapping as well.(74)F Staying at someone's home puts you in a neighborhood that can give you a better representation of the life and culture in the place you're visiting.(75)E The next time you want to spend your vacation in a new place,but don't want to pay a fortune,check what's posted online and find a house to swap.
A.House swapping is most common in New York and Paris.
B.Hotels are often quite difficult to book when you want to explore a new home.
C.A lot of times,this extra cost prevents travelers from going very far from home.
D.To swap houses,people check the Internet for others planning to travel and trade homes.
E.With many house swapping sites growing,this new phenomenon is becoming easier than ever.
F.Hotels are often located where few people live,making them a strange place to experience a city.
G.On the other hand,if there were trouble,people could write about that to wan others not to trust the swappers.
