Almost everyone knows the meaning of "Mr.", "Mrs.", and "Miss&q
Almost everyone knows the meaning of "Mr.", "Mrs.", and "Miss". "Mr." is used before the names of gentlemen. "Mrs." is for married women and "Miss" is for single women. But what is "Ms."?For some time, businessmen in the US have used "Ms." before a woman's name when they do not know whether or not the woman is marrieD.Today, however, many women prefer to use "Ms." rather than "Mrs." or "Miss". The word "Mr." does not tell us whether a man is married or not. Many women think this is an advantage for men. They want to be equal to men in this way. These women feel that it is not important for people to know whether or not they are marrieD.There are some problems with "Ms.", however. Not all women like it. Some like the older ways of doing things. Some find it difficult to pronounce. ("Ms." sounds like [miz].) Generally, young women like it better than older women do. It is difficult to know whether "Ms." will be used by more American women in the future or not. What do you think of this change?1. Many young women prefer to use "Ms." because ________.：A.they think themselves as good as menB.it doesn't tell whether they're married or notC.the word sounds more pleasant than "Mrs." doesD.the word has been used for a long time

Many words from Chinese and English are different in both the denotational meanings and connotational meanings. Which of the following is an example for this?()
A.龙/dragonB.猫头鹰/owlC.狐狸/foxD.猪/pig
考题
Animals are friends of human beings, so the languages of all nations contain a lot of words about animals. Certain words for animals do carry similar denotative and connotative meanings in both languages. In English, for instance, “dove” is often related to “peace”, and in Chinese we have a similar term “和平鸽”. Another example is that “fox” and “狐狸” both imply the quality of “being sly”, as is obvious in the idioms of “as sly as a fox” and “像狐狸一样狡猾”.However, there are many words with the same denotative meanings but different connotative meanings. For instance, “bat” is an evil animal in European folk legends. The English idioms like “as blind as a bat” and “as crazy as a bat” give explanation by themselves. But many Chinese people believe that “bat” is the symbol of good luck, health and happiness. This is mainly because in “蝙蝠” “蝠” is pronounced the same with “福” (good fortune) in “幸福” (happiness) and “洪福” (limitless blessing).Still, there are many other words whose denotative and connotative meanings are both different in English and Chinese. For example, in the western world, “dragon” is a fire-spitting mythical animal, signifying violence, as in “He is a bit of dragon here.” By contrast, most Chinese people regard “龙” (Long) as a symbol of dignity and power, as in the idiom “望子成龙” (hold high hopes for one’s child).1. Some English words about animals carry both denotative and connotative meanings.()A.TrueB.False2. Many words from Chinese and English are the same in both the denotational meanings and connotational meanings, such as “fox” and “狐狸”.()A.TrueB.False3. The Chinese word “蝙蝠” carries the same connotative meanings with the English word “bat”.()A.TrueB.False4. The Chinese word “龙” carries the same denotative meaning with the English word “dragon”.()A.TrueB.False5.“He is a bit of dragon here.” The equivalent Chinese version of this sentence is: 他在这一带为非作歹。()A.TrueB.False

Passage Four"Cool" is a word with many meanings. Its old meaning is used to express a temperature that is a little bit cold. As the world has changed, the word has had many different meanings."Cool" can be used to express feelings of interest in almost anything. When you see a famous car in the street, maybe you will say, "It's cool. ' You may think, "He's so cool," when you see your favorite football player.We all maximize (扩大) the meaning of "cool". You can use it instead of many words such as "new" or "surprising". Here's an interesting story we can use to show the way the word is used. A teacher asked her students to write about the waterfall (瀑布) they had visited. On one student's paper was just the one sentence, "It's so cool." Maybe he thought it was the best way to show what he saw and felt.But the story also shows a scarcity of words. Without "cool", some people have no words to show the same meaning. So it is quite important to keep some credibility (可信性). Can you think of many other words that make your life as colorful as the word "cool"? I can. And I think they are also very cool.46. We know that the word "cool" has had______.A. only one meaningB. no meaningsC. the same meaningD. many different meanings

Music Used as a Healing Therapy1 .Music has long been used to treat patients suffering from different problems.In 400 BC,its healing properties were documented by the ancient Greeks. More recently,in both world wars in the last century, medical workers used music therapy（疗法）with people suf-fering from trauma（外伤）.Currently, it is used as a treatment for many diseases, such as cancer,and it has also been used with patients with long-term pain and learning disabilities.2 .There is growing evidence that music can caused physical changes to the body which can im-prove our health. In the Welcome Trust study,which took place over three years at the Chelsea and Westminster hospital in London,patients were asked to listen to musical perform-ances. As a result,it was found that stress levels were significantly reduced,recovery times were improved,and fewer drugs were needed.3. These very positive results are partly due to general well-being（良好的健康状况）.It is already accepted that when people feel happy and have a positive approach to life,they are more likely to feel better and recover from disease quickly. Music increases this feeling of joy and adds to the recovery process.4 .However,not all these benefits can be attributed to an increase in general well-being. Music has other effects which have not yet been understood. According to Professor Robert-son,a scientist and musician,some effects of music are mysterious and are,therefore,being investigated further. It has been suggested that the sounds and rhythms of music help stimu-late the brain and send electrical messages to the muscles.5 .Science,however,demands facts and hard evidence. Many in the medical profession have not yet recognized the healing benefits of music,since reports have been based mainly on various stories of evidence. These new studies could provide proof to doctors that music is a suitable treatment for many conditions. One day doctors may even “prescribe”（开处方） music,but that could be a long time in the future.Those who always look on the bright side of life are more likely to______.A: recover from disease quicklyB: there is not enough hard evidenceC: use their minds activelyD: it improves general well-beingE: listen to musical performancesF: it brings many other benefits

资料：Anything that affects the smooth flow of information is known as noise. This might be, for example, the language used,an in appropriate use of technology or the different levels of skill and knowledge of the sender and receiver. For example, every day in the press and on TV, consumers are bombarded with often confusing or contradictory information about the health benefits or risks associated with different foods. Consumers may not have enough understanding or information to judge between conflicting messages. It is therefore not surprising that many people do not hear these messages and switch off.
A company has to overcome a considerable amount of direct noise caused by the earlier negative press articles. By not responding to these immediately or correcting with facts, consumers are confused and the company loses credibility with the press and the public.
To achieve its vision and encourage consumers to eat turkey all year round, BM Company needs to give people more information in a way they can easily understand. It has there closed to highlight key facts about the products as the foundation for many of its messages.
What may not be called noise according the passage?
A.positive press articles
B.the different levels of skill and knowledge of the sender and receiver.
C.the language used.
D.an inappropriate use of technology.

单选题请阅读 Passage 1，完成第 21~25小题。Passage 1These days，many large city buildings are equipped with their own air-conditioning systems.These systems help keep the buildings cool，but they can also damage the environment.Since they use a lot of electricity，for instance，they contribute indirectly to global warming.In addition，the water that flows through the systems is often cooled using chemicals called chlorofluorocarbons，or CFCs，that are believed to damage the Earth's ozone layer.Recently，though，a system has been built in the city of Toronto，Canada，that cools buildings with little damage to the environment. In the traditional air-conditioning systems found in most large buildings，water is pumped through the building in a continuous cycle.The water is first cooled to a temperature of 4℃ in machines called chillers.It is then sent to individual units that cool the air in each room.As the water flows through the building，it gradually becomes warmer.Finally，it reaches the roof ，where it is left to cool down naturally in a water tower.After that it is returned to the chillers，where the cycle begins again.Toronto lies on the shore of Lake Ontario，one of North America's Great Lakes，and the new system makes use of cold water taken from about 80 meters below the surface of the lake.At this depth，the water in the lake remains at 4℃ all year round.This is exactly the temperature to which the water in air-conditioning systems is cooled.However，the water from the lake is not pumped directly into the air-conditioning systems.Instead，it is used to cool the water that is already inside the air-conditioning systems.After that，the lake water is added to the city's ordinary water supply.Enwave，the company that developed this deep-lake cooling system，says that it uses 75 percent less energy than traditional air conditioning.And since no CFCs are used，no damage can be caused to the ozone layer.Not every city is located next to a large lake，but experts believe that systems like the one being used in Toronto could be built elsewhere by using other natural sources of cold water.What happens in the end to the water from Lake Ontario?A
It is used by the residents of Toronto.B
It is returned to a place deep in the lake.C
It is cooled down before being used again.D
It is added to the water inside air-conditioning systems.

In the traditional air-conditioning systems found in most large buildings，water is pumped through the building in a continuous cycle.The water is first cooled to a temperature of 4℃ in machines called chillers.It is then sent to individual units that cool the air in each room.As the water flows through the building，it gradually becomes warmer.Finally，it reaches the roof ，where it is left to cool down naturally in a water tower.After that it is returned to the chillers，where the cycle begins again.Toronto lies on the shore of Lake Ontario，one of North America's Great Lakes，and the new system makes use of cold water taken from about 80 meters below the surface of the lake.At this depth，the water in the lake remains at 4℃ all year round.This is exactly the temperature to which the water in air-conditioning systems is cooled.However，the water from the lake is not pumped directly into the air-conditioning systems.Instead，it is used to cool the water that is already inside the air-conditioning systems.After that，the lake water is added to the city's ordinary water supply.Enwave，the company that developed this deep-lake cooling system，says that it uses 75 percent less energy than traditional air conditioning.And since no CFCs are used，no damage can be caused to the ozone layer.Not every city is located next to a large lake，but experts believe that systems like the one being used in Toronto could be built elsewhere by using other natural sources of cold water.What is the function of the chillers in a traditional air-conditioning system?A
They pump the air continuously to the units in each room.B
They lower the temperature of the water in the system.C
They help the water cool down naturally on the roof .D
They gradually clean the water as it flows through the building.

It keeps buildings much cooler than other methods.B
It can be used by large cities anywhere in the world.C
It is much more energy-efficient than traditional systems.D
It keeps water from being used for more than one purpose.
