Annealing

Annealing is a way of making metal softer by heating it and then letting it cool very slowly, if metal is heated and then cooled very quickly, for example by dipping(浸) it in water, it will be very hard but also very brittle(脆)—that is, it will break easily. Metal that has been annealed is soft but does not breaks as easily. It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other material, such as glass.

Dear Doctor，

　　My husband and I got married in 1995 and for the first ten years of our marriage I was very happy to stay home and raise our three children．Then four years ago，our youngest child went to school and I thought I might go back to work．

　　My husband was very supportive and helped me to make my decision．He emphasized all of the things l can do around the house，and said he thought I could be a great success in business．

　　After several weeks of job-hunting，l found my present job，which is working for a small public relations firm．At first，my husband was very proud of me and would tell his friends，“My clever little wife can run that company she's working for．”

　　But as his joking remark was close to reality，my husband stopped talking to me about my job．I have received several promotions and pay increases，and I am now making more money than he is．I can buy my own clothes and a new car．Because of our combined incomes，my husband and I can do many things that we had always dreamed of doing，but we don't do these things because he is very unhappy．

　　We fight about little things and my husband is very critical of me in front of our friends．For the first time in our marriage，l think there is a possibility that our marriage may come to an end．

　　I hove my husband very much，and I do not want him to feel inferior，but I also love my job．I think I can be a good wife and a working woman，but I don't know how．Can you give me some advice？Will I have to choose one or the other or can I keep both my husband and my new career？

　　Please help．

Every summer, a great many students travel to other countries looking for work and adventure. Most of the 1 are in seasonal work, mainly connected with tourism and 2 . The pay is usually poor, but most people work abroad for the 3 of travel. You can pick grapes in France, entertain (逗乐) kids on American summer camps, and, of course, there are 4 jobs in hotels and restaurants.

    But it is not easy now to find work, “ 5 you speak the language of the country well, there will be very few openings,”says Anthea Ellis, an adviser on 6 for students.“If you work with a family in Italy, you’ll have to speak Italian. When you wash dishes in a restaurant in Paris, the owner will expect you to speak 7 .British students only have a language 8 for jobs in the USA and Australia.”

    9 enjoys the experience. Sarah James was employed to help forty American children in Europe. The two teachers with the children had never been 10 . One child lost his passport; another became seriously ill and was 11 home; the whole group was thrown out of one hotel because of the 12 they made, and Sarah herself was robbed on her only 13 evening of the entire trip.“I did visit a lot of new places,”she says,“but it wasn’t worth it. The pay was 14 and it really was a 24-hour-a-day job. The kids never slept!”

    “The trouble is, students expect to have 15 time of it,”Anthea Ellis points out.“ 16 , they see it as a holiday. In practice, 17 , you have to work hard. At the same time, all vacation work is casual (临时) work. You’ll have a job when the hotel, the restaurant or the campsite is busy. 18 , you’ll work if it’s convenient for the company that employs you. But you have 19 employment rights. As soon as the holiday season  20 , they’ll get rid of you.”
