3.You may think your bathroom is often full of bacteria(細菌) and so you give it a complete cleaning once a week.But how often do you clean out and disinfect(消毒) your fridge?Well,probably not often enough,according to a recent study,which found out that the fridge is the second dirtiest place in your house,just behind the bathroom.
Fridge temperatures were often set too high,allowing the growth of bacteria,which included E.coil,Enterobacteria,and S.a(chǎn)ureus,all of which will give you an easy access to food poisoning.So what can you do to ensure your fridge---and your food in it---is not a health threat?
For starters,clean the fridge weekly---wipe it and repeat.
Make sure your fridge is at the correct temperature for storing food,between 0and 5degrees centigrade.Your freezer should be below-18degrees centigrade.You can use fridge and freezer thermeters to make sure this is the case.
Some modern fridges have zones to store different types of food,such as meat and vegetables.Make sure you don′t store meat in the vegetable zone,as the temperature there might be higher.
Make sure you don not leave the door open too long as the temperature in the fridge will quickly rise,creating a breeding(繁殖) ground for bacteria.
Cover food that has not been finished,and eat it within a couple of days.
Keep bottles and jars closed.
Keep raw meat away from cooked meat.Both should be well covered to prevent pollution.
Store raw meat at the bottom of the fridge to stop juices dripping onto other foods.
Finally,use common sense,and throw away old food.

33.What do we know from the first paragraph?C
A.People often clean their fridges once a week.
B.A recent study shows the bathroom is the dirtiest place in the house.
C.Many people don′t believe that the fridge is a dirty place.
D.The fridge may not have as many bacteria as the bathroom.
34.Which is the best temperature for storing your food in the fridge?C
A.10°C   B.-2°C    C.4°C   D.-18°C
35.The purpose of this text is toD.
A. introduce some common knowledge about fridges
B.teach people how to fix their fridges
C.guide people to store food properly in their fridges
D. let people know how to keep their fridges clean.

14.Laptop computers are popular all over the world.People use them on trains and airplanes,in airports and hotels.These laptops connect people to their workplace.In the United States today,laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want.Within five years,each of the 1500students at the college will receive a laptop.The laptops are part of a$10million computer program at Westlake,a 110-year-old college.The students with laptops will also have access to the Internet.In addition,they will be able to use e-mail to speakwith their teachers,their classmates,and their families.However,the most important part of the laptop program is that students will be able to use computers without going to computer labs.They can work with it at home,in a fast-food restaurant or under the trees-anywhere at all!

At Westlake College,more than 60percent of the staff use computers.The laptops will allow all teachers to use computers in their lessons.As one Westlake teacher said,"Here we are in the middle of Virginia and we're giving students a window on the world.They can see everything and do everything."

46.The main purpose of the laptop program is to give each student a laptop toB.

18.Swimming is one of those activities that can be learned early in life.Little children can learn to swim as soon as they walk.In fact,you need the same skills in walking as in swimming.However,I believe that five is the best age to learn.By five or six,a child knows fear of water,a very important thing to know.It's wise to be afraid,to recognize true danger.Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming,every swimmer should learn,as soon as possible,these four basic strokes:butterfly,backstroke,breaststroke,and crawl.I feel that one of these---the breaststroke is different from the others,since some young swimmers use this stroke naturally,without any training.
In swimming there are certain rules every swimmer should follow:
1.Never swim alone!No matter how good you are in the water,don't risk drowning by swimming alone.If you swim by yourself,with no life guards or friends with you,you may get into trouble.
2.Don't go beyond your abilities.Most swimmers know enough not to swim too far from the bank or the beach.Showing off by doing dangerous tricks is no good.Swim safely and you will continue to swim and alive.
3.Don't smoke.Swimming depends on a healthy body; good lungs are part of it.
4.Work at any activity that builds muscles.
59.Little children can learn to swim as soon asB.
A.they can talk                   
B.they start walking
C.they have no fear of the water      
D.they are five or six years old 
60.The author believes that fear of water isB.
A.stupid                          
B.sensible(明智的)    
C.dangerous                   
D.not smart 
61.The stroke that some young swimmers use first isC.
A.butterfly                       
B.backstroke   
C.breaststroke                    
D.crawl
62.According to the passage,you should not swim alone becauseD.
A.the water is too cold             
B.your parents would not be happy 
C.something in the water might attack   
D.you might drown.

8."There is nothing either good or bad,but thinking makes it so."-William Shakespeare,Hamlet.One of the greatest sources of unhappiness,in my experience,is the difficulty we have in accepting things as they are.
  When we see something we don't like,we wish it could be different-we cry out for something better.That may be human nature,or perhaps it's something that's ingrained in our culture.
An example:in my recent article,A Beautiful Method to Find Peace of Mind,quite a few people thought my view was too negative because I said you should expect people to mess up,expect things to go differently than you planned,and that you should accept that willingly.
It's too negative to expect things to go wrong,they said.However,it's only negative if you see it as negative,if you judge it as bad.Instead,you could accept it as the way the world works-as the way things actually are.And try to understand why that is,and embrace it as it is.Accept these things as they are,and try to understand why they're that way.
Does it mean you can never change things and make this world a better place?Not at all.But not because the world is full of misery,but because that's the path you choose to take,because you enjoy that path and the process of change.
  Try a different approach:accept,and understand.It might lead to some interesting results.
63.What does the underlined word"ingrained"in the second paragraph mean?C
A.celebrated       B.followed         C.rooted       D.liked
64.What does the author mean by saying the underlined sentence in the third paragraph?A
A.People should take the world as the way it actually works.
B.The world is negative if people see and judge it as negative.
C.In current society we can expect nothing but mess-up people and go-wrong things.
D.We must try to understand what is nature of the world.
65.According to the article,people change the world becauseB.
A.the world is full of misery              B.they enjoy the process of change
C.they can't understand the world         D.they are kind people
66.Which of the following titles best sums up the whole passage?D
A.Change the world
B.Heal the world

12.Eat like a king in the morning,a prince at noon,and a peasant at night.This saying is all about the importance of breakfast.And now scientists can tell us just why it's so important.According to a study carried out at Imperial College London,UK,skipping the first meal of the day not only means you eat more at lunch,but also that your brain wants to find more unhealthy foods.
The study suggests that there is a special part of our brain called the orbitofrontal cortex (眶額皮層),which plays an important part in making choices about what we eat.It is used for identifying the taste of food,especially when skipping breakfast.It is more likely to target high-calorie foods when you're on an empty stomach.
Scientists did an experiment on this.Dr Tony Goldstone from Imperial College London,scanned (掃描) the brains of 21 men and women,around the age of 25.On the first day,these people skipped breakfast before the scans.On the second day,they had cereal (谷物),bread and jam as breakfast.After the scan on both days,they had their lunch.
When the volunteers had skipped breakfast,they ate around 20 percent more at lunch,compared with days when they had eaten breakfast.?Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods."We believe that bit identifies the value of foods-how pleasant,how delicious something is,"Goldstone told The Guardian.
36.From Paragraph 1,we learn thatA.
A.scientists found out why eating breakfast is important
B.it's easy to lose weight without breakfast
C.there's no need to have good food for supper
D.eating breakfast makes your brain smarter
37.Which of the following is NOT true about the orbitofrontal cortex?B
A.It is part of our brain.B.It tells people to eat breakfast.

38.Which is the correct order for the experiment on the first day?C
①The volunteers skipped breakfast.
②The volunteers had lunch.
③The volunteers had a brain scan.
A.①②③B.③②①C.①③②D.③①②
39.In the experiment,the volunteers without breakfast ate about 20%Dat lunch.
A.of the usual breakfast                 B.more than the usual breakfast
C.of the usual lunch                       D.more than the usual lunch
40.Which of the following can be the title for this passage?A
