Dogs have long been used to find explosives and drugs.Now,a new study shows that man’s best friend can also help to find lung and breast cancer,researchers report in integrative Cancer Therapies.The findings show that trained ordinary household dogs can detect early—stage lung and breast cancers by smelling the breath samples of patients.
Researchers have found that cancer cells send out molecules different from those of healthy ones,and that might be sensed by smell by the highly sensitive dog’s nose.
For the study,five dogs were trained by a professional instructor to respond differently to breath samples of healthy and cancer patients.“The dogs learned to sit or lie down in front of cancer patient samples and to ignore control samples through the method of food reward,” McCulloch explained.
After a period of training,researchers tested the animals’ability to distinguish cancer patients from controls.The animals were given breath samples from 55 patients with lung cancer,3 1 with breast cancer and 83 healthy controls who were not included in the original training period.
McCulloch’s group found that the dogs were able to correctly distinguish the breath samples of cancer patients from those of the control subjects in about 90 percent of the cases.The dogs were also able to detecting early-stage lung and breast cancers.
“These results show that there is hope for early detection,”McCulloch said.The re-searches are planning to conduct further studies on the breath composition of cancer patients to possibly design an electronic device that can do the dogs’job.“A dog’s nose is so powerful it can detect odors(气味)10 000 to 100 000 times better than a human nose can.I hope people will be interested in doing this research,”McCulloch added,“It shows that there is definitely something out there.”

The first field season is now over at the hut village of the workmen who built the tombs in the Valley of the Kings.However,the archaeologists working on the excavation(挖掘)have found that they still have a great deal to do.The sun,the wind and tourists have left their mark on the village,originally discovered by Bernard Bruyhre in 1935.
“From our modern perspective,it is upsetting to see how the village was first excavated and then left to be destroyed.Passers-by have used the huts as rubbish dumps and restrooms,”says Jaana Toivari—Viitala,a teacher at the University of Helsinki.“Fortunately,while we still have some surface cleaning to do,conservation are off to a good start.’’
The hut viliage offers rare insight into everyday life in ancient Egypt.
“In the early twentieth century,archaeologists were only interested in the tombs of kings. The workmen’s huts they discovered were seen as a necessary evil in the quest for the real trea sures.’,
“Now several international research groups on different excavations are examining everyday life and work in the Valley of the Kings.This seems to be a trend in archaeology right now.”Toivari-Viitala says.
Her research group wants to find out why the hut village was built on the slope of a mountain,halfway between the construction site and Deir-el-Medina.They are also interested in how many workers lived in the village at a time,when they lived there,and what their role was in the construction work.
“Comparing the names found in the village and in Deir-el-Medina provides useful information.Judging from the construction methods,settlement in the village can be divided into two separate periods:the initial settlement and a later one.”
For the time being,much is up to guessing,but Toivari-Viitala believes that the coming four field seasons,three months each,will see results.
“The working conditions are not nearly as difficult as I thought they would be. The cool winds in the mountains nicely alleviate the heat.”
The research group working on the“Workmen’s huts in the Theban mountains”project is planning to return to the Valley of the Kings in October.
71.What does the passage mainly talk about?
A.The hut village in the Valley of the Kings.
B.The excavation of the tombs in the Valley.
C.The archaeologists working on the excavation.
D.Everyday life and work in the Valley of the Kings.

A.It has been damaged a lot.
B.It can tell us a lot about ancient Egypt.
C.It has attracted archaeologists’attention.
D.It has a lot of real treasures somewhere in it.
73.What’s the new trend in archaeology right now according to Toivari-Viitala?
A.Being interested in the tombs of kings.
B.Examining everyday life and work in the Valley of the Kings.
C.Using the huts as rubbish dumps and restrooms.
D.Guessing what the result will be beforehand.
74.From the passage we know that the author is one of   
A.the workmen who built the tombs in the Valley of the Kings
B.the archaeologists working on the excavation of the village
C.those in favour of Toivari-Viitala’s ideas and plans
D.the passers-by who used the huts as dumps and restrooms

C.the research group working on the workmen’s huts will suffer a lot
D.the hut village is much more valued by archaeologists than the tombs

Decisions, decisions! Our lives are full of them, from the small ones to the life-changing. The right to choose is central to everyone. Yet sometimes we make bad decisions that leave us unhappy or full of regret. Can science help?
Most of us know little about the mental processes that lie behind our decisions. Luckily, what psychologists are finding may help us all make better choices. Here are some of their amazing discoveries to help you make up your mind.
Consider your emotions. You might think that emotions are the enemy of decision-making, but in fact they are a part of it. Whenever you make up your mind, your brain’s emotional centre is active. University of Southern California scientist, Antonio Damasia, has studied people with damage to only the emotional parts of their brains, and found that they were unable to make basic choices about what to wear or eat. Damasia thinks this may be because our brains store emotional memories of past choice, which we use to help the present decision-making.
However, making choices under the influence of an emotion can greatly affect the result. Take anger for example. A study by Nitika Garg of the University of Mississippi and other scientists found the angry shoppers were more likely to choose the first thing they were offered rather than considering other choices. It seems that anger can lead us to make quick decisions without much thinking.
All emotions affect our thinking and motivation,so it may be best to avoid making important decisions under their influence. Yet strangely there is one emotion that seems to help us make good choices. The American researchers found that sad people took time to consider the various choices on offer, and ended up making the best choices. In fact many studies show that people who feel unhappy have the most reasonable view of the world.
1. What does the underlined word “central” mean?
A. in the middle    B. easy to reach          C. important      D. having power
2. Damasia’s study suggests that ________.
A. emotions are the enemy of decision-making.
B. our brain has nothing to do with decision-making.
C. people with physical damage find it hard to make up their minds.
D. our emotional memories of past choices can affect present decisions.
3. According to the text, what may help us make better decisions?
A. To think about happy times.                  
B. To make many decisions at a time.
C. To stop feeling regretful about the past.
D. To learn about the process of decision-making.
4. Why are angry shoppers more likely to choose the first thing they are offered?
A. They often forget their past choices.         B. They make decisions without much thinking.
C. They tend to save time when shopping.  D. They are too angry to bargain.
5. What do we learn from the text?
A. Emotions are a part of decision-making.
B. Sad people always make worse choices.
C. No emotion seems to help us make good choices.
D. Only sad feelings affect our thinking and motivation.

If your life feels like it is lacking the power that you want and the motivation that you need, sometimes all you have to do is shift your point of view.
By training your thoughts to concentrate on the bright side of things, you are more likely to have the incentive(刺激,诱因) to follow through on your goals. You are less likely to be held back by negative ideas that might limit your performance.
Your life can be enhanced(增强的), and your happiness enriched, when you choose to change your perspective(远景、希望). Don't leave your future to chance, or wait for things to get better mysteriously on their own. You must go in the direction of your hopes and aspirations. Begin to build your confidence, and work through problems rather than avoid them. Remember that power is not necessarily control over situations, but the ability to deal with whatever comes your way.
Always believe that good things are possible, and remember that mistakes can be lessons that lead to discoveries. Take your fear and transform it into trust; learn to rise above anxiety and doubt. Turn your "worry hours" into "productive hours". Take the energy that you have wasted and direct it toward every worthwhile effort that you can be involved in. You will see beautiful things happen when you allow yourself to experience the joys of life. You will find happiness when you adopt positive thinking into your daily routine and make it an important part of your world.
64. What is the best title for the passage?                                 
A. Live every day                                                           B.Treat every day actively                        
C. Turn your "worry hours" into "productive hours"       D. How to live

A. Positive thinking                               B. Negative ideas      
C. Worry hours                                  D. Productive hours

Air is an odorless(that cannot be smelled;smelless),invisible(that cannot be seen)gas that surrounds the planet earth.It is everywhere on the planet.An “empty” drinking glass and an “empty” room,to give two examples,are not really empty.Each is filled with air.When the glass is filled with water,the water pushes the air out of the glass.
Air,as a gas,has no definite(fixed,particular)shape,but,because it is matter,it takes up space.It is easy to prove that air is something that takes up space.Stuff a dry handkerchief into the bottom of a glass so that it will not fall out when the glass is turned upside-down.Push the upside-down glass,hold it straight into a jar of water till the glass is completely covered.When the glass is taken out of water,the handkerchief will be dry.The air inside the glass took up space and kept the water from coming in.
1.“Stuff a dry handkerchief into…”.The underlined word means.
A.Press tightly     B.Take out          C.Put down     D.Turn fully
2.The writer tells us that _________.

How clean are the nation’s homes?
According to a survey by CIF, there’s room for improvement all over Britain.
Love or hate it — cleaning your home is one job you simply can’t ignore(忽视). But that’s not to say everyone spends the same amount of time or effort on making their places spotless. A new survey by CIF— experts on making tough cleaning jobs easier—— shows that when it comes to washing windows or cleaning the oven(烤箱),where you live in the UK it may show how much effort you put into the task.
BATHROOM
25% of men have never cleaned the toilet — but those in Wales are the worst. Nearly four in 10 Welsh men said they never cleaned anywhere in the house. Hate cleaning the shower head? You’re not alone — a  quarter of a million Brits say the same. 20% of Scots regard window-cleaning as their most hated job.
KITCHEN
36% of people in the south-east say cleaning the cooker is their hated task. 68% of those in the north-east spend more than six hours a week cleaning their homes — especially the kitchen — in sharp contrast to the 49% of Welsh and West Country folk, who put their hands up to cleaning for under an hour.
BEDROOM
18% believe cleaning starts here: that’s the percentage of women who clean wearing their dressing gowns. 51% of women in the north-west may be staying in bed and giving their husband a cuddle(拥抱)—as a thank-you for helping them clean. In other places, there are far fewer helpful men.
LIVING ROOM
32% of women in the north-east turn up the stereo to help make the dusting more fun. Almost six in 10 women agree, however, that cleaning is seriously energetic exercise.
SHIFT THE DIRT WITH CIF
It’s no secret that the right cleaning products will cut cleaning time and effort in half— and no one knows that better than How Clean Is Your house? Presenters Aggie Mackenzie and Kim Woodburn. For solutions(解决办法)to all your cleaning needs, here are some of CIF’s top tips:
·Stop a lot of build-up on your shower head—give it a quick squirt(喷洒)with CIF bathroom spray once a week.
·Stainless steel(不锈钢)tools seem to need endless cleaning. The CIF Wild Qrchid Qxy-Gel-it lifts dirt easily and leaves the kitchen smelling fresh and clean.
·Cooking outside? CIF cream will get your barbecue (烤架)spotlessly clean, ready for those long, lazy summer evenings. Perfect!
小题1:The main purpose of this passage is to ______.
A.tell us the results of a certain survey
B.advertise a certain product
