Summarize the effects of nitrogen on the weld quality and the related mechanism.

Passage One Questions 1 to 5 are based on the following passage. In late April, 33-year-old Li Yang climbed into her new car, Suzuki Alto and headed west. She “just kept going to see how far I could get.” Six days and 1,600 miles later, she arrived in Lhasa, the Tibetan capital. Exhausted and excited, she wrote an article and put it on the Internet, documenting her adventure with digital photos. For centuries such freedom of movement has been unimaginable in China. In feudal times, poverty, bad roads, and imperial edict confined people to the villages where they were born. Now all that is changing. With China’s economic development for decades, car ownership is suddenly within reach of millions of ordinary Chinese. As incomes rise, new car prices fall down quickly, and the government adds new roadways, many Chinese people think that it is enjoyable to have their own cars instead of bicycles. The increasing number of cars has launched a new cultural revolution, transforming Chinese life and society in many ways, just like what happened in America 50 years ago. The most obvious change is the traffic. Beijing’s broad streets are now filled with cars at rush hour. In Shanghai the bridges and tunnels crossing the Huangpu River witness so many cars that a cab ride from one side to the other can take more than an hour. To prevent traffic jams, the Shanghai city government auctions a limited number of new car license plates each month. Even with these restrictions, the number of cars on Chinese roads is increasing so fast it poses a grave threat to the environment and could reshape the global economics of oil. Private cars have brought about a new class of commuters, who drive to downtown office towers from spacious, modern homes in the suburbs. “I enjoy the drive,” says the manager of a Dutch food company, who takes the 30-minute-trip to his office in the center of Shanghai. He lives with his wife and infant son in a gated community with a familiar name: Long Island. “It would be probably cheaper to take a taxi every day,” he said. “But this way, I feel more comfortable and have more freedom.” 3. More and more cars have brought about a lot of changes, except ______.

Whenever we could, Joan and I took refuge in the streets of Gibraltar. The Englishman's home is his castle because he has not much choice. There is nowhere to sit in the streets of England, not even, after twilight, in the public gardens. The climate, very often, does not even permit him to walk outside. Naturally, he stays indoors and creates a cocoon of comfort. That was the way we lived in Leeds.

These southern people, on the other hand, look outwards. The Gibraltarian home is, typically, a small and crowded apartment up several flights of dark and dirty stairs. In it, one, two or even three old people share a few ill-lit rooms with the young family. Once he has eaten, changed his clothes, embraced his wife, kissed his children and his parents, there is nothing to keep the southern man at home. He hurries out, taking even his breakfast coffee at his local bar. He comes home late for his afternoon meal after an appetitive hour at his cafe. He sleeps for an hour, dresses, goes out again and stays out until late at night. His wife does not miss him, for she is out, too—at the market in the morning and in the afternoon sitting with other mothers, baby-minding in the sun.

The usual Gibraltarian home has no sitting-room, living-room or lounge. The parlour of our working-class houses "would be an intolerable -waste of space. Easy-chairs, sofas and such-like furniture are unknown. There are no bookshelves, because there are no books. Talking and drinking, as well as eating, are done on hard chairs round the dining-table, between a sideboard decorated with the best glasses and an inevitable display cabinet full of family treasures, photographs and souvenirs. The elaborate chandelier over this table proclaims it as the hub of the household and of the family. 'Hearth and home' makes very little sense in Gibraltaf. One's home is one's town or village, and one's hearth is the sunshine.

Our northern towns are dormitories with cubicles, by comparison. When we congregate— in the churches it used to be, now in the cinema, say, impersonally, or at public meetings, formally—we are scarcely ever man to man. Only in our pubs can you find the truly gregarious and communal spirit surviving, and in England even the pubs are divided along class lines.

Along this Mediterranean coast, home is only a refuge and a retreat. The people live together in the open air—in the street, market-place. Down here, there is a far stronger feeling of community than we had ever known. In crowded and circumscribed Gibraltar, with its complicated inter-marriages, its identity of interests, its surviving sense of siege, one can see and feel an integrated society.

To live in a tiny town with all the organization of a state, with Viceroy (总督), Premier, Parliament, Press and Pentagon, all in miniature, all within arm's reach, is an intensive course in civics. In such an environment, nothing can be hidden, for better or for worse. One's successes are seen and recognized; one's failures are immediately exposed. Social consciousness is at its strongest, with the result that there is a constant and firm pressure towards good social behaviour, towards courtesy and kindness. Gibraltar, with all its faults, is the friendliest and most tolerant of places. Straight from the cynical anonymity of a big city, we luxuriated in its happy personalism. We look back on it, like all its exiled sons and daughters, with true affection.

Which of the following best explains the differences in ways of living between the English and the Gibraltarians?

A．The family structure.

B．Religious belief.

C．The climate.

D．Bating habit.
