单选题 Two techniques have recently been developed to simplify research and reduce the number of nonhuman primates needed in studies of certain complex hormonal reactions. One technique involves the culturing of primate pituitary cells and the cells of certain human turnouts. In the other, animal oviduct tissue is transplanted under the skin of laboratory primates. Both culturing techniques complement existing methods of studying intact animals. With an in vitro culturing technique, researchers are deciphering how biochemical agents regulate the secretion of prolactin, the pituitary hormone that promotes milk production. The cultured cells survive for as long as a month, and they do not require serum, a commonly used culture ingredient that can influence cellular function and confound study results. One primate pituitary gland may yield enough cells for as many as 72 culture dishes, which otherwise would require as many animals. The other technique allows scientists to monitor cellular differentiation in the reproductive tracts of female monkeys. While falling short of the long-sought goal of developing an in vitro model of the female reproductive system, the next-best alternative was achieved. The method involves transplanting oviduct tissue to an easily accessible site under the skin, where the grafted cells behave exactly as if they were in their normal environment. In about 80 percent of the grafts, blood vessels in surrounding abdominal skin grow into and begin nourishing the oviduct tissue. Otherwise, the tissue is largely isolated, walled off by the surrounding skin. A cyst forms that shrinks and swells in tandem with stages of the menstrual cycle. With about 80 percent of the grafts re-establishing themselves in the new site, a single monkey may bear as many as 20 miniature oviducts that are easily accessible for study. Because samples are removed with a simple procedure requiring only local anaesthesia, scientists can track changes in oviduct cells over short intervals. In contrast, repeated analysis of cellular changes within the oviduct itself would require abdominal surgery every time a sample was taken--a procedure that the animals could not tolerate. Scientists are using the grafting technique to study chlamydia infections, a leading cause of infertility among women. By infecting oviduct tissues transplanted into the abdominal skin of rhesus monkeys, researchers hope to determine how the bacteria cause pelvic inflammatory disease and lesions that obstruct the oviduct. Such research could eventually lead to the development of antibodies to the infectious agent and a strategy for producing a chlamydia vaccine.

单选题With the US economy slowing down, layoffs are everywhere. No industry is spared. If you end up having to start over, in addition to starting your job search, there are several things you should take care of to make your transition a smooth one. First and foremost, clear up any misunderstanding about how and why you left your last job with your exb0ss. Whether you left voluntarily, were fired or were laid off due to budget cutbacks, make sure you both have the same explanation. Agree on job titles accordingly. Also ask for a reference if you think your ex-boss will offer one and you trust that he or she will speak honestly about your performance. You should have a source of emergency cash that you can use in the interim. Don't panic and liquidate your stocks and bonds just yet, be optimistic in your prospects while also be more frugal than usual. You should save money on not having to dry clean work clothes so often and eating less take-out lunches. Save money by not eating out at restaurants and watch videos rather than going to the movies every weekend. Make a note of your job-hunting expenses, such as career counselor consulting fees and resume printing costs, and save the receipts. By next year's taxfIIing time, you could get deductions on your job-search expense (unless you left a job willingly or was a college graduate looking for your first job). Most companies terminate your medical insurance coverage as soon as you stop working for them. But it doesn't mean you have to forgo medical coverage altogether. There is something called Consolidated Omnibus Budget Reconciliation Act (COBRA) in the United States that legally protects an ex-employee's right to stay in the company's health care plan. However, the company will stop paying your premiums, and you will have to pay out of your pocket the expenses-This is still a good option compared to no health insurance at all. Another important thing to take care of when you change jobs is your 401 (k) account. A 401 (k) is the retirement fund that most companies offer. It's named after section 401 (k) in the Internal Revenue Service's policy documents. You put aside a percentage of your paycheck each pay period, and the money accumulated will be managed by the 401 (k) fund manager your employer has hired and is invested in the stock market. You cannot withdraw money from this account until you reach this age, or you will incur penalties. When you leave a job, the money can sometimes be kept with your ex-employer for a while. It's always a good idea to compare your new employer's 401 (k) plan with your old one. Every company offers different types of investment options, form over- seas stocks to high-tech stocks and everything in between. If you do want to transfer the account to your new employer, you need to go to the human resources department and ask for forms that help you make the transition. Don't forget to ask for job leads form your ex-coworker. Even if you are leaving for a job in an- other industry, you never know what people they happen to know that can help with your job search. Keep in touch with the friends you have make at your old job. Remember to anchor yourself to people, not institutions, and you will find that any transition is made easier.

单选题Justice in society must include both a fair trial to the accused and the selection of an appropriate punishment for those proven guilty. Because justice is regarded as one form of equality, we find in its earlier expression the idea of a punishment equal to the crime. Recorded in the Bible is the expression "an eye for an eye, and a tooth for a tooth." That is, the individual who has done wrong has committed an offense against society. To make repayment for this offense, society must get equally balanced, which can be done only by imposing an equal injury upon him. This conception of deserved-punishment justice is reflected in many parts of the legal codes and procedures of modern times, which is illustrated when we demand the death penalty for a person who has committed murder. This philosophy of punishment was supported by the German idealist Hegel, who believed that society owed it to the criminal to put into operation a punishment equal to the crime he had committed. The criminal had by his own actions denied his true self and it is necessary to do something that will eliminate this denial and restore the self that has been denied. To the murderer nothing less than giving up his life will pay his debt. The demand for the death penalty is a right the state owes the criminal and it should not deny him what he deserves. Modern jurists have tried to replace deserved-punishment justice with the notion of corrective justice. The aim of the latter is not to abandon the concept of equality but to find a more adequate way to express it. It tries to preserve the idea of equal opportunity for each individual to realize the best that is in him. This does not mean that criminals will escape punishment or be quickly returned to take up careers of crime. It means that justice is to heal the individual, not simply to get even with him. Therefore, his conviction of crime must not deprive him of the opportunity to make his way in the society of which he is a part.
