Ireland has had a very difficult history. The problems started in the 16th century when English rulers tried to conquer(征服) Ireland. For hundreds of years, the Irish people fought against the English. Finally, in 1921, the British government was forced to give independence to the south of Ireland. The result is that today there are two “Irelands”. Northern Ireland, in the north, is part of the united kingdom. The Republic of Ireland, in the south, is an independent country.
In the 1840s the main crop, potatoes, was affected by disease and about 750,000 people died of hunger. This, and a shortage (短缺) of work , forced many people to leave Ireland and live in the USA, the UK, Australia and Canada. As a result of these problems, the population fell from 8.2 million in 1841 to 6.6 million in 1851.
For many years, the majority of Irish people earned their living as farmers. Today, many people still work on the land but more and more people are moving to the cities to work in factories and offices. Life in the cities is very different from life in the countryside, where things move at a quieter and slower pace.
The Irish are famous for being warm-hearted and friendly. Oscar Wilde, a famous Irish writer, once said that the Irish were “the greatest talkers since the Greeks”. Since independence, Ireland has revived(复兴) its own culture of music, language, literature and singing. Different areas have different styles of old Irish song which are sung without instruments. Other kinds of Irish music use many different instruments such as the violin, whistles, etc. What does the author tell us in paragraph 1?
| A．How the Irish fought against the English. |
| B．How Ireland gained independence. |

Facial expressions carry meaning that is determined by situations and relationships. For example, in American culture (文化) the smile is in general an expression of pleasure. Yet it also has other uses. A woman's smile at a police officer does not carry the same meaning as the smile she gives to a young child. A smile may show love or politeness. It can also hide true feelings. It often causes confusion(困惑) across cultures. For example, many people in Russia consider smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in public places(although this is less common in big cities). Some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don't smile enough. In Southeast Asian cultures, a smile is frequently used to cover painful feelings. Vietnamese people may tell a sad story but end the story with a smile.
Our faces show emotions(情感), but we should not attempt to “read” people from another culture as we would “read” someone from our own culture. The fact that members of one culture do not express their emotions as openly as do members of another does not mean that they do not experience emotions. Rather, there are cultural differences in the amount of facial expressiveness permitted. For example, in public and in formal situations many Japanese do not show their emotions as freely as Americans do. When with friends, Japanese and Americans seem to show their emotions similarly.
It is difficult to generalize about Americans and facial expressiveness because of personal and cultural differences in the United States. People from certain cultural backgrounds in the United States seem to be more facially expressive than others. The key is to try not to judge people whose ways of showing emotion are different. If we judge according to our own cultural habits, we may make the mistake of “reading” the other person incorrectly.What does the smile usually mean in the U．S.?
| A．Love. |
| B．Politeness. |
| C．Joy. |
| D．Thankfulness. |
The author mentions the smile of the Vietnamese to prove that a smile can ________.
| A．show friendliness to strangers |
| B．be used to hide true feelings |
| C．be used in the wrong places |
| D．show personal habits |
What should we do before attempting to “read” people?
| A．Learn about their relations with others. |
| B．Understand their cultural backgrounds. |
| C．Find out about their past experience. |
| D．Figure out what they will do next. |
What would be the best title for the text?
| A．Cultural Differences |
| B．Smiles and Relationships |
| C．Facial Expressiveness |
| D．Habits and Emotions |
You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.
First, you must ask yourself，“Where is the wind coming from? Is it coming from ahead or behind or from the side？”You must think about this all the time on the boat. The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90°angle(角度)to the boat. Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45°angle to the boat.Itneeds to be out far enough to catch the wind, but it shouldn't flap(摆动)．It shouldn't look like a flag on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.
Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can't go in a straight line. You must go first in one direction and then in another. This is called tacking.When you are tacking, you must always keep the sail inside the boat.What should you consider first while sailing?
| A．Sailors' strength. |
| B．Wave levels. |
| C．Wind directions. |
| D．Size of sails. |
What does the word “It” underlined in Paragraph 4 refer to?
| A．The boat. |
| B．The wind. |
| C．The sail. |
| D．The angle. |
What do you have to do when sailing against the wind?
| A．Move in a straight line. |
| B．Allow the sail to flap. |
| C．Lower the sail. |
| D．Tack the boat. |
Where can you probably find the text?
| A．In a popular magazine. |
| B．In a tourist guidebook. |
| C．In a physics textbook. |
| D．In an official report. |
Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their pets are just as used to the warm shelter(住所) as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you're cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of nonfrozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye onyour pet's water. Sometimes owners don't realize that a water bowl has frozen and their pet can't get anything to drink. Animals that don't have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.What do we learn about pets from Paragraph1?
| A．They are often forgotten by their owners. |
| B．They are used to living outdoors. |
| C．They build their own shelters. |
| D．They like to stay in warm places. |
Why are pet owners asked to stay with their pets when they are out in cold weather?
| A．To know when to bring them inside. |
| B．To keep them from eating bad food. |
| C．To help them find shelters. |
| D．To keep them company. |
If pets are left on their own outdoors in cold weather, they may ________.
| A．run short of clean water |
| B．dig deep holes for fun |
| C．dirty the snow nearby |
| D．get lost in the wild |
What is the purpose of this text?
| A．To solve a problem. |
| B．To give practical advice. |

A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”. This idea is dangerous.
Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.
Some people go even further. They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ——somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of hopelessness and discourages them from making efforts to build a safer world.
In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling” science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict. u
Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future. What can we conclude from the recent study?
| A．People think highly of science. |
| B．People hold mixed opinions about science. |
| C．Science is getting dangerously out of control. |
| D．Science is used for both good and bad purposes. |
According to the passage, what will happen if we hold that science is getting beyond control?
| A．The development of science will hopelessly slow down. |
| B．Businesses will have even greater influence on science. |
| C．The public will lose faith in bringing about a bright future. |
| D．People will work more actively to put science under control. |
The discussion should reach beyond scientific societies because __________.
| A．scientists have failed to predict the outcomes u |
| B．the ties between different areas need strengthening u |
| C．united efforts are necessary for the development of science u |
| D．people need to work together to prevent the bad use of science u |
What is the main idea of the passage?
| A．Science and its applications bring us many dangers. |
| B．The development of science mostly lies in people’s attitudes. |
| C．Mankind can largely take control of science with their efforts. |
| D．The future of science will be influenced by the dangerous ideas. |
