  The common cold is the world's most widespread illness, which is plagues (疫病) that flesh receives.

  The most widespread fallacy (谬误) of all is that colds caused by cold.They are not.They are caused by viruses (病毒) passing on from person to person.You catch a cold by coming into contact, directly or indirectly, with someone who already has one.If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever.But they do not.And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.

  During the First World War soldiers who spent long periods in the trenches (战壕),cold and wet, showed no increased tendency to catch colds.

  In the Second World War prisoners at the notorious Auschwitz concentration camp (奥斯维辛集中营) naked and starving, were astonished to find that they seldom had colds.

  At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time.After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room.Some wore wet socks all day while others exercised in the rain until close to exhaustion.Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.

  If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most painstaking research, no one has yet found the answer.One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.

  No one has yet found a cure for the cold.There are drugs and pain suppressors (止痛片) such as aspirin, but all they do is to relieve the symptoms.

  In 1930, a young African American, Vivien T.Thomas, a professional carpenter, was hired as a lab assistant by a famous white doctor named Dr.Alfred Blalock.Although he   1   went to college, he had an enormous   2   to learn and explore the power of knowledge.Whenever Dr.Blalock left his office, young Thomas used to   3   study the medical books on the shelves of the office.

  Thomas   4   a great interest in learning more and more about   5   when he started to assist Blalock during his practice of surgeries on dogs.  6   Dr.Blalock understood Thomas's ability to help him perform a complicated surgery, he still did not   7   Thomas as a smart person because of the social   8   of prejudice towards African Americans.

  Dr.Blalock wanted to   9   to believe that Thomas was just a(n)   10   by profession and a lab assistant.Employees, white or black, at the hospital could not   11   that an African American, Thomas, could run the lab.He was the   12   and thus a history maker.

  In those days, the society expected that black people were   13   to be janitors(管理员).Despite this reality, Thomas’ cleverness, perseverance, and passion had   14   a need in Dr.Blalock's mind.Thomas ran John Hopkins Hospital's surgical(外科的)lab   15   Dr.Blalock.At the time, all other   16   employees in the hospital were janitors.Dr.Blalock and Thomas became a   17   and conducted a joint research that   18   the first heart surgery performed at John Hopkins University Hospital in 1941.

  Many years later, Thomas's contribution was   19   and he was eventually awarded an honorary doctorate, for his creative work in the   20   procedures of modern cardiac(心脏病的)surgery.As he became Dr.Thomas, he also inspired and lifted the confidence of the future generation.He used his knowledge for the betterment of humankind.

阅读理解

  Packaging(包装)is an important form of advertising.A package can sometimes motivate someone to buy a product.For example, a small child might ask for a breakfast food that comes in a box with a picture of a TV character.The child is more interested in the picture than in breakfast food.

  Pictures for children to color or cut out, games printed on a package, or small gifts inside a box also motivate many children to buy products-or to ask their parents for them.

  Some packages suggest that a buyer will get something for nothing.Food products sold in reusable containers are examples of this.Although a similar product in a plain container might cost less, people often prefer to buy the product in a reusable glass or dish, because they believe the container is free.However, the cost of the container is added to the cost of the product.

  The size of a package also motivates a buyer.Maybe the package has“Economy Size”or“Family Size”printed on it.This suggests that the larger size has the most product for the least money.But that is not always true.To find it out a buyer has to know how the product is sold and the price of the basic unit.

  The information on the package should provide some answers.But the important thing for any buyer to remember is that a package is often an advertisement.The words and pictures do not tell the whole story.Only the product inside can do that.

From the passage we know the buyer pays more attention to ________.

[  ]

(3)

What suggestion does the author give in the passage?

[  ]

A.

It’s not good to buy the product which is sold in a glass or dish

B.

The quality of a container has nothing to do with the quality of the product.

C.

The best choice for a buyer is to buy a product in a plain package

D.

A buyer should buy what he needs most rather than a well-designed package

(4)

PART FOUR WRITING

Read the following passage.Fill in the numbered blanks by using the information for the passage.Write NO MORE THAN 3 WORDS for each answer.

  A Low-Carbon Economy(LCE)refers to an economy which has a minimal emission of greenhouse gas(GHG), namely, carbon dioxide into the biosphere(生物圈).Recently, most of the scientists and the public hold the opinion that the climate is changing because there is such an accumulation of CO2 in the atmosphere due to human activities.The over-concentration of these gases is producing global warming that affects long-term climate, with negative impacts on humanity in the foreseeable future.LCE, therefore, is proposed as a means to avoid catastrophic climate change.

  All nations which are considered carbon intensive societies and societies which are heavily populated should become zero-carbon societies and economies.Several of these countries have promised to become 'low carbon' but not entirely zero carbon, and claim that emissions will be cut by 100% by balancing emissions rather than ceasing all emissions.

  Nuclear power and the strategies of carbon capture and storage(CCS)have been proposed as the primary means to achieve a LCE while continuing to exploit non-renewable resources.Scientists are afraid, however, whether the spent-nuclear-fuel can be stored, and whether it is secure.Also they are not certain about the costs and time needed to successfully implement CCS worldwide and whether the stored emissions will leak into the biosphere or not.Alternatively, many have proposed renewable energy should be the main basis of a LCE, but, they have their associated problems of high-cost and inefficiency; this is changing, however, since investment and production have been growing significantly in recent times.Furthermore, it has been proposed that to make the transition to an LCE economically attractive we would have to attach a cost(per unit output)to GHGs through means such as emissions trading and/or a carbon tax.

  A LCE is aimed to integrate all aspects of itself from its manufacturing, agriculture, transportation to power-generation around technologies that produce energy and materials with little GHG emission and thus around populations, buildings, machines and devices which use those energies and materials efficiently and dispose of or recycle its wastes so as to have a minimal output of GHGs.

Title:  1  

Ⅰ.  2  :an economy with a minimal output of GHG

Ⅱ.  3   of the present economy:

●global warming

●long-term climate change

  4   on humanity

Ⅲ.  5  :

to produce energy and materials with little GHG emission

to use those energies and materials efficiently

to have   6   of GHGs

Ⅳ.  7   to achieve a LCE:

●nuclear power

●the strategies of carbon capture and storage

renewable energy

  8  

●a carbon tax

Ⅴ.  9  :

●spent-nuclear-fuel storage/storage of spent-nuclear-fuel

Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body.

Our bodies use varying(不同程度的) amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight. In order to avoid becoming overweight, it is advisable to eat a balanced diet and not eat too many foods that have a high calorie rating. The table below gives you some idea of the number of calories in food.

A. Meats

Slice of bacon 50

Hamburger 300

Slice of beef 100

Sausage 180
