时间稍微超了一点，可是有一个问题，字数总是达不到500字，因为中间总是有停顿思考的时候。该怎么办，背模板吗？

76.The following appeared as part of an article in a health and beauty magazine.

"A group of volunteers participated in a study of consumer responses to the new Luxess face cream. Every morning for a month, they washed their faces with mild soap and then applied Luxess. At the end of that month, most volunteers reported a marked improvement in the way their skin looked and felt. Thus it appears that Luxess is truly effective in improving the condition of facial skin."

一组志愿者参加了一项关于消费者对新的Luxess面霜的反应的调查。在一个月的每个早晨，他们都用柔和香皂洗脸然后使用Luxess。一个月后，多数志愿者报告说他们皮肤的观感显著改。因此，这说明Luxess对于改面部皮肤状况确实有效。

Before describing large qualities of recommending the conclusion that using Luxess can effectively improves the condition of facial skin, the evidences given in the argument should be carefully examined from several angels. To explain the assertion, the arguer cites a experiment that a group of volunteers participate an experience to use the Luxess every morning in a whole month and at last most of the volunteers fell better. How ever, it is obviously groundless to achieve the conclusion.

First, the arguer is failing to provide the detailed information of how the volunteers are selected. In fact, the effect of the face cream is relevant with the quality of the tester’s oriental skin. If all the volunteers are high-quality skin before they use the Luxess, the result of the experiment is unnecessary with the Luxess. Only when the volunteers are selected randomly and represented of the common people’s skin statue, then the experiment can be used as the evidence. In short, to better evaluate the relationship between the experiment and the Luxess’s function, the arguer must provide the information of the attending volunteers.

Second, the experiment is lasted only one month, which is left dubious time period for a experiment. As we know, all the healthy experiment should be lasted for an enough period, some special ones can even last for several years. The arguer doesn’t show whether one month is enough. The experiment time is important because some medicine’s effect will be appeared after a long time. In addition, the volunteers are using the Luxess only in the morning, once a day, while some consumers like to use face cream more times or in the other time such in afternoon or before going to bed. The argument does not give guarantee that different using time will lead to the same effect. So it’s not proper to persuade people to using the Luxee.

Third, after the experiment, most volunteers reported the good effect of the Luxess, but the arguer does not indicate any information about the other volunteers. What’s the result of the other volunteers? Did they fell worse than before? What’s the proportion of this kind of people? It’s crucial information to evaluate the effect of the Luxess. This is obvious needing as a experiment report.

Finally, the arguer is failing to consider the other alternatives. Such alternatives may include the effect other similar products in current market and the cost of the Luxess. All these factors can influence the consumer’s activities.

In summary, the arguer is lacks much detailed and critic information about the experiment and other facts. To better convincing the conclusion, the arguer should provide more evidences about the volunteers and the experiment result.
