Falling temperatures are no excuse to avoid outdoor exercise with your dog. Along with making sure you are appropriately dressed, your dog should also be properly protected from the elements. Some large breed dogs such as Labrador Retrievers, Golden Retrievers, German Shepherds and Huskies can tolerate the colder weather better than others. These dogs may also develop a thicker coat over time as they are exposed to colder weather.
Smaller breeds, however, like Chihuahuas and Miniature Pinschers, breeds with short coats and puppies should wear some type of protection, i.e, a coat or sweater, if the temperature drops too low. Look for coats or sweaters with high collars or a turtleneck that covers your dog from the base of the tail on top to the belly underneath.
Dog booties (毛线鞋) provide good protection from chemicals or salts on the pavement as well as mud. If you don’t use the booties, be sure to wipe your dog’s paw pads with room temperature water after taking it outside.
Other tips
When you bathe your dog, dry him completely before taking him out in the cold weather for a walk or exercise. It is especially important to keep your dog well groomed (打扮) during the winter months to protect him from the elements.
If your dog frequently participates in outdoor activities during the colder months, increase his food intake, especially protein, to help keep his coat grow thick and healthy. Dogs that are not as active during the winter months may need to have their food consumption reduced.
The amount of time you spend outside with your dog will depend on his size, breed type and age. Remember that ill or elderly dogs are more sensitive to cold weather. Dogs whom cold weather agrees with can spend hours outside without getting cold but some of the smaller and younger dogs’ exercise sessions should be kept shorter. Dogs should not be left outside unattended.
Another activity to consider is doggie daycare, which is an excellent alternative during cold weather months. It’s a great place for your dog to get plenty of physical and mental stimulation while being with other dogs.

There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.
People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend(hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing(批评) and being disliked is perhaps taken up by imitation(模仿). It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.
Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrongdoings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact(接触) with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

In the atmosphere, carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping.
According to a weather expert' s prediction, the atmosphere will be 3℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere (北半球), possibly resulting in an alteration of the earth's chief food growing zones.
In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.
Satellite pictures show that large areas of Antarctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth.
However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude , therefore, that up to now natural influences on the weather have gone beyond those caused by man. The question is: Which natural cause has most effect on the weather?
One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot spots and "cold" spots (that is, the relatively less hot spots) on the sun. As the sun rotates (使旋转), every 27. 5 days, it presents hotter or "colder" faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth's atmospheric pressure, and consequently on wind circulation. The sun is also changeable over a long term: its heat output goes up and down in cycles, the latest trend being downward.
Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is not. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia (惯性) of the earth's climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun's fading heat .
66. It can be concluded that a concentration of carbon dioxide in the atmosphere would_________.
A. mean a warming-up in the Antarctic
B. raise the temperature of the earth' s surface
C. prevent the sun's rays from reaching the earth's surface
D. explain the cause of great changes in the climate in the northern hemisphere
67.The article was written to explain ___________.
A. the greenhouse effect
B. the solar effects on the earth
C. the causes affecting weather
D. the models of solar-weather interactions
68. Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling. This is__________.
A. mainly because the levels of carbon dioxide are rising
B. partly due to changes in the output of solar energy
C. possibly because the ice caps in the poles are melting
D. only due to the effect of the inertia of the earth' s climate
69. On the basis of their models, scientists believe the opinion that__________.
A. the climate of the world should be becoming cooler
B. the new Ice Age will be delayed by the greenhouse effect
C. the man-made warming effect helps to increase the solar effects
D. it will take thousands of years for the inertia of the earth's climate to take effect
70. If the assumption about the delay of a new Ice age is correct, ____________.
A. ice would soon cover the northern hemisphere
B. the greenhouse effect could work in favor of the earth
C. the best way to overcome the cooling effect would be to burn more fuels
D. the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly
Remember how great exercise was when you were a little kid? Back then, racing around the playground or skipping rope for hours, you weren’t thinking fitness, you were thinking entertainment. But in this age of high-tech home equipment and underused gym memberships, the simple joy of jumping rope has been forgotten, Rediscovering it will give you a total-body exercise you can find.
Although considered an excellent form of exercise, jumping rope has never gained widespread acceptance because of two fundamental reasons. First, most people recognize jumping rope as an excellent form of cardiovascular(心血管的)exercise, but they also believe that it is simply too difficult. In other words, they don’t think they’ll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial physical outcome. Second, many view it as somewhat boring and overly repetitive not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun if you find a proper way to practice it. Instead of doing the usual two-foot bounce over and over again, people good at rope-jumping often change their pattern every 10 or 20 jumps. A single bounce, a double-bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping.
Now researchers are learning that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres to perform in parallel to each other. In short, jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life.
61. From the first paragraph we learn that_________.
A. jumping rope has faded from people’s memories
B. people now have more advanced equipment

63.The first sentence in the 3rd paragraph implies_________.
A. there is only one proper way to follow
B. the usual way should not be used
C. the easiest way is always the best
D. there are many ways to follow
64.According to the researchers, jumping rope_________.
A. only prepares the brain for learning
B. is suitable for students only
C. helps both brain hemispheres work together
D. can be dangerous for old people
65.What is the author’s attitude towards rope jumping?
A. He is arguing against it
B. He is in favor of it

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships .One strength of the human condition is our possibility to give and receive support from one another under stressful conditions .Social support makes up of the exchange of resources among people based on their interpersonal ties .Those of us with strong support systems appear better able to cope with major life changes and daily hassles(困难). People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people fend off(挡开) illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways .First, friends, relatives and co-workers may let us know that they value us .Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support .They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力)us from our worries and troubles. Finally, other people may give us instrumental support—money aid ,material resources, and needed services—that reduces stress by helping us resolve and cope with our problems.
56. Interpersonal relationships are important because _______.
A. they are indispensable(不可缺少的)to people’s social well-being
B. they awaken people’s desire to exchange resources
C. they help people to cope with life in the information era
D. they can cure a range of illnesses such as heart disease, etc
57. Research shows that people's physical and mental health _______.
A. relies on the social medical care systems which support them
B. has much to do with the amount of support they get from others
C. depends on their ability to deal with daily worries and troubles
D. is closely related to their strength for coping with major changes in their lives
58. Which of the following is closest in meaning to the underlined word “cushions”?
(Line 1, Para 2)
A. adds up to B. does away with
C. lessens the effect of D. lays the foundation for
59. Helping a sick neighbor with some repair work is an example of _______.
A. instrumental support B. informational support

60. Social companionship is beneficial in that__________.
A. it helps strengthen our ties with relatives
B. it enables us to eliminate our faults and mistakes
C. it makes our leisure-time activities more enjoyable
D. it draws our attention away from our worries and troubles
What caused this strange occurrence? This is a question that had long puzzled people who study fish. The answer turned out to be a combination of wind and storm.
When it is spring in the northern part of the world, it is fall in Australia. Throughout the autumn season, terrible storms arise and rains flood the land. The strong winds sweep over Australia like huge vacuum cleaners, collecting seaweed, pieces of wood, and even schools of fish. Strong winds may carry these bits of nature for many miles before dropping them on fields, houses, and astonished people.
Although they seem unusual, fish-falls occur quite frequently in Australia. When Bill Tapp was asked to describe the scene of fish, he remarked, “They look like millions of dead birds falling down.” His statement is not surprising. The wonders of the natural world are as common as rain. Nature, with its infinite wonders, can create waterfalls that flow upward and fish that fall out of the sky.
56. What is this passage about?
A. A sad story. B. A rain of fish.
C. Australia’s northern part. D. The damage done by floods.
57. Fish-falls occur in Australia_________ .

C. only in winter D. when the air is calm
58. It is a known fact that ________.
A. one should watch where one steps
B. Bill Tapp is a scientist who studies farming
C. the natural world can never create waterfalls that fall upward
D. the seasons in the southern part are different from those in the northern part
