success.According to the study,if the cat is adopted before the dog,and if they are introduced when still
young (less than 6 months for cats,a year for dogs),it is highly probable that the two pets will get along
swimmingly.Twothirds of the homes interviewed reported a positive relationship between their cat and dog.
However,it wasn"t all sweetness and light.There was a reported coldness between the cat and dog in
25% of the homes,while aggression and fighting were observed in 10% of the homes.One reason for this is probably that some of their body signals are just opposite.For example,when a cat turns its head away it
signals aggression,while a dog doing the same signals submission.
In homes with cats and dogs living peacefully,researchers observed a surprising behaviour.They are
learning how to talk each other"s language.It is a surprise that cats can learn how to talk"Dog",and dogs can learn how to talk"Cat"．
What"s interesting is that both cats and dogs have appeared to develop their intelligence.They can learn to read each other"s body signals,suggesting that the two may have more in common than was previously
suspected.Once familiar with each other"s presence and body language,cats and dogs can play together,
greet each other nose to nose,and enjoy sleeping together on the sofa.They can easily share the same
water bowl and in some cases groom (梳理)each other.
The significance of this research on cats and dogs may go beyond pets-to people who don"t get along,
including neighbors,colleagues at work,and even world superpowers.If cats and dogs can learn to get
along,surely people have a good chance.

older?Try picking up the phone and speaking to someone.Scientists have found that holding a simple
conversation could be just as effective as playing popular "braintraining" games that have reproduced a
multimillion pound industry.
Researchers compared 36 studies on memory exercises performed between 1970 and 2007.Some
studies suggested both healthy older adults and those with mild cognitive impairment (轻度认知缺陷)
could remember words better after some memory training.
However,other studies found this improvement was matched by those who were asked to hold a
discussion about art.
The finding that social interaction could be just as effective at keeping memory loss at bay comes after Age Concern warned more than a million people aged over 65 lived alone in their own homes.The charity warned solitary lifestyles were a "silent epidemic (静默的流行病)"spreading through the nation quickly.
Dr Martin said most people experienced a cognitive decline in old age.This can include memory loss
and inability to plan,pay close attention or perform tasks as quickly as before.The normal rate of decline
seems to speed up in some people,leading to a condition called mild cognitive impairment,which some
researchers see as a reason for developing mental diseases later in life.
Although several studies have suggested that braintraining exercises could delay signs of cognitive
decline,the studies and the types of training have many different kinds.The findings do not mean that longer,more intense or different exercises might not be effective,but that those which have been reported thus far
have only limited effect.
Dr Martin concluded researchers needed to improve the way they used their studies to eventually
determine ways of preventing cognitive decline in old age.
1．What is the main idea of Paragraph 1?
A．People should play more "braintraining" games.
B．Training has a great effect on our health.
C．Having a conversation can improve memory
D．People have no ways to improve memory
2．What does the underlined word "solitary" probably mean?
A．Unhealthy.
B．Alone.
C．Enjoying being alone.
D．Lacking patience.
3．Mild cognitive impairment can cause people to ________.
A．have mental diseases
B．develop physical diseases
C．worry about the coming of old age
D．escape from the reality in life
4．What message can be implied in the passage?
A．Most people suffer from memory loss.
B．There are more social problems to be settled at present.
C．No one can prevent old age from coming.
D．Whether "braintraining" exercises have a great effect on memory is not sure.
5．The passage would be of great help to ________.
A．children
B．housewives
C．elderly people
D．badtempered people
What to Expect
The host will provide accommodation and meals.Rooms will be cleaned and bedcovers changed at least once a week.You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.
Accommodation Zones
Homestays are located in London mainly in Zones 2,3 and 4 of the transport system.Most hosts do not live in the town centre as much of central London is commercial and not residential (居住的)．Zones 3 and 4 often offer larger accommodation in a less crowded area.It is very convenient to travel in London by Underground.
Meal Plans Available
◇Continental Breakfast
◇Breakfast and Dinner

and plants need water. Man also needs water. We need water to drink, to cook our food and to clean
ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.
There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part
of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The
water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapor (蒸气).
Clouds are made of water. They may be made of very small drops of water. They may also be made
of snow crystal
s(结晶体). Snow crystals are very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.
Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is
a liquid, you can drink it. When it is a gas, you can not see or feel it.
1. Where can we find water?

prevent your cuts from becoming infected. Can medicine come in chicken eggs? A team of scientists
from Scotland says "yes." They"ve kept some special chickens that lay eggs with disease-treating drugs
inside.
These drugs are made of molecules called proteins. Animals make thousands of proteins-they"re the
main ingredients(成分) in skin, hair, milk, and meat. Since animals can make proteins easily, they"re
good animals for making protein drugs.
Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk.
But chickens are cheaper to take care of, need less room, and grow faster than these other animals.
"Those qualities could make chickens a better choice to become living drug factories." says Simon
Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens" DNA-the code that tells cells how to make
proteins-so that the birds" c
ells made two protein drugs. One drug can treat skin cancer, and the othertreats a nerve disease called multiple sclerosis.
The scientists changed the chickens" DNA so that the birds made these drugs only in their egg whites.
This protects the chickens" bodies from the drugs" possible harmful effects and makes it easy for scientists
to collect the drugs.
These special chickens can pass on their drug-laying abilities to their chicks. So far, the Scottish
researchers have kept five generations of drug-producing chickens. But the scientists need to improve
these chickens. The chickens don"t make enough drugs to treat people yet. Once the researchers perfect
their technique, you might eventually take your medicine from chicken eggs.
1. What is the best title of the passage?
A. Animals and Protein Drugs.
B. Medicine Packaged in Various Forms.
C. A Scotland Scientist and His Chickens.
D.Chickens: a Better Choice of Living Drug Factories.
2. Which of the following is Not True according to the passage?
A. It takes much shorter time for chickens to grow than cows, sheep and goats.
B. Compared to cows, sheep and goats, chickens are less expensive to be raised.
C. Chickens can produce the best quality of drugs among the drug-producing animals.
D. Chickens are smaller in size than cows, sheep and goats and therefore need less room.
3. Why did the chickens make the drugs only in the egg whites?
A. Because it will help to collect the drugs easily.
B. Because it will not change the DNA of the chickens.
C. Because it will be easy for the patients to take the drugs.
D. Because it will prevent possible harmful effects on the patients.
4. What can be inferred from the passage?
A.Scottish researchers have kept five more drug-producing chickens.
B.This technique still needs improving so as to satisfy the normal application.
C.In the future people with diseases will take eggs instead of pills.
D. The chicks need to be improved so as to carry the same ability as their parents.
Attitudes to AIDS Now
Most people say that the USA is making progress in fighting AIDS, but they don"t know there"s no cure and strongly disagree that "the AIDS epidemic(流行病)is over," a new survey finds.
The findings, released Thursday by the Kaiser Family Foundation, reassure activists who have worried
that public concern about AIDS might disappear in light of recent news about advances in treatment and
declines in deaths.
"While people are very optimistic about the advances, they"re still realistic about the fact that there is no cure" says Sophia Chang, director of HIV programs at the foundation.
The Kaiser survey, like a recent USA TODAY Gallup Poll, does find that the number of people
ranking AIDS as the country"s top health problem has fallen. In the Kaiser Poll, 38% say it"s the top
concern, down from 44% in a 1996 poll; in the Gallup Poll, 29% say AIDS in No.1, down from 41% in
1992 and 67% in 1987.
Other findings from Kaiser, which polled more than 1,200 adults in September and October and asked additional questions of another 1,000 adults in November:
52% say the country is making progress against AIDS, up from 32% in 1995.
52% say the government spends too little on AIDS.
86% correctly say AIDS drugs can now lengthen lives; an equal number correctly say that the drugs are not cures.
67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24% know deaths fell.
Daniel Zingale, director of AIDS Action Council, says, "I"m encouraged that the American people are
getting the message that the AIDS epidemic isn"t over. I hope the decision-makers in Washington are
getting the same message… We have seen signs of complacency(自鸣得意).
1. According to the Kaiser Poll, which of the following is NOT correct?
A. The country is making progress against AIDS.
B. AIDS drugs still cannot save people"s lives.
C. AIDS drugs can now make people live longer.
D. More and more people die of AIDS now.
2. The word "message" in the last paragraph means .
A. printed new
B. contact

3. What do activists worry about?
A. Recent news about AIDS is not true.

C. Deaths caused by AIDS may not decline.
D. Advances in AIDS treatment are too slow.
4. According to the passage, people"s attitude toward the cure of AIDS is .
A. optimistic.
