德茂公司诉荣发公司货款一案经人民法院二审审结后，于2002年5月15日做出判决，责令荣发公司在判决生效后10日内向德茂公司给付货款200万元。但荣发公司却没有在指定的期间内履行判决。于是德茂公司在2002年7月25日向人民法院申请强制执行。根据上述案情，请回答以下各题。

如果在强制执行中，荣发公司和德茂公司自行和解达成了和解协议，约定德茂公司再宽限2个月，荣发公司将于2002年10月1日将200万划人德茂公司的账户，那么对此分析正确的是：

A．执行法院应该不予承认，因为案件已经进入执行程序，当事人不能再私自和解

B．执行员应当将和解协议记入笔录，并且暂时中止强制执行

C．如果荣发公司没有按照和解协议的约定履行义务的，德茂公司可以申请法院执行他们的和解协议

D．如果荣发公司按照和解协议的约定履行了义务的，人民法院应当对该案做执行结案处理

(46) For centuries the smoking of tobacco in cigarettes, cigars, and pipes has produced controversy over possible health hazards, but only since the 1950’s has sufficient scientific evidence accumulated to make possible a thorough evaluation of the health risk.

Scientific investigation of the relationship of smoking and health gained impetus after the beginning of the 20^th century, then an increase in lung cancer was noted. As the use of tobacco increased, studies improved. (47) Although some gaps in knowledge still exist, the information now available is sufficient to permit making sound judgments, based on the converging lines of evidence.

(48) Investigators have directed their principal consideration to cigarette smoking because the health consequences attributed to it far exceed those due to smoking cigars and pipes. The widespread popularity of cigarettes is comparatively recent in man’s use of tobacco. The smoking pattern began to change at the beginning of the 20th century. Since then, cigarettes have steadily become more popular than cigars and pipes. (49) In the United States. per capita cigarette consumption — calculated for all persons 15 years of age and older, regardless of whether they smoked—rose from 49 per year in 1900 to 3,888 in 1960. Per capita consumption of cigars, pipe tobacco, and chewing tobacco declined sharply in the same period. Data presented in 1966 indicated a sharp reduction in cigarette smoking in the United States for men under the age of 55 with the trend continuing to 1970.

Further increase in cigarette consumption for women of all ages was reported in 1966 and no further increase was noted 1966 and 1970. However, in 1970 overall per capita cigarette consumption rose.

By 1962 the Royal College of Physicians of London reported:" Cigarette smoking is a cause of lung cancer and bronchitis, and various other less common diseases. It delays healing of gastric and duodenal ulcers." Some scientists, however, expressed dissenting opinions.

The most widely publicized report in the United States was issued in 1964 by the Surgeon General’s Advisory Committee on Smoking and Health. (50) The principal judgment in the committee’s 150,000-word report was: "Cigarette smoking is a health hazard of sufficient importance in the United States to warrant appropriate remedial action." The smokers of pipes and cigars were found to incur less health risk. However, the incidence of cancer and heart disease among them was found to be greater than among nonsmokers.
