公安机关和检察机关在本案诉讼活动中有哪些做法违反诉讼程序规定，为什么

For some people, it’s easy to get dressed for work. Pilots and police officers, for example, don’t have to make decisions about their work clothes. They wear uniforms to work every day.

For many office workers, however, it is more difficult to choose clothes for work. They do not wear uniforms to the office. Also, many organizations are changing their dress codes. They are allowing their employees to wear casual(随意的) clothes to work.

The change to casual work clothes began in the 1990s. At first, many companies in the United States allowed employees to wear casual clothes on one day of the week—Friday. Friday became “Casual Friday” or “Dress-down Friday”. Today, however, many companies are allowing their employees to wear casual clothes every day of the week.

Some studies show that people are producing and achieving more when they are wearing comfortable clothes. Some companies also like the casual dress code because they don’t need to buy special clothes for work. They can save money this way.

Unfortunately, a casual dress code can also cause problems. Sometimes employees think they can wear anything. Many companies have rules about casual clothes. They list the kinds of clothes that are not “business-casual” clothes. Blue jeans, sandals, and sportswear are examples of clothes that are usually too casual for the office.

In ancient Greek, the term euthanatos meant "easy death". Today euthanasia (安乐死) generally refers to mercy killing, the voluntary (自愿) ending of the life of someone who is terminally ill. Like abortion, euthanasia has become a legal, medical, and moral issue over which opinion is divided.

Euthanasia can be either active or passive. Active euthanasia means that a physician or other medical personnel takes an action that will result in death, such as giving an overdose of deadly medicine. Passive euthanasia means letting a patient die for lack of treatment, or stopping the treatment that has begun. Examples of passive euthanasia include taking patients off a breathing machine or removing other life-support systems. Stopping the food supply is also considered passive.

A good deal of the debate about mercy killing originates from the decision-making process. Who decides whether a patient is to die This issue has not been solved legally in the United States. The matter is left to state law, which usually allows the physician in charge to suggest the option of death to a patient’s relatives, especially if the patient is brain dead. In an attempt to make decisions about when their own lives should end, several terminally ill patients in the early 1990s used a controversial suicide device, developed by Dr. Jack Kevorkian, to end their lives.In parts of Europe, the decision-making process has become very flexible. Even in cases where the patients are not brain dead, patients have been put to death without their approval at the request of relatives or at the suggestion of physicians. Many cases of passive euthanasia involve old people or newborn infants. The principle justifying this practice is that such individuals have a "life not worthy of life".In countries where passive euthanasia is not legal, the court systems have proved very tolerant in dealing with medical personnel who practice it. In Japan, for example, if physicians follow certain guidelines they may actively carry out mercy killings on hopelessly ill people. Courts have also been somewhat tolerant of friends or relatives who have assisted terminally ill patients to die.

A. negative

B. positive

C. objective

D. casual
