阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 The Ice Age Twenty thousand years ago, the earth was held in control by relentlessly (不宽容地) probing fingers of ice that drew power from frigid strongholds in the north and crept southwestward to bury forests, fields, and mountains. Landscapes that were violated by the slowly moving glaciers(冰川 )would carry the scars of this advance far into the future. Temperatures dropped deeply, and land surfaces in many parts of the world were depressed by the unrelenting weight of the thrusting ice. At the same time, so much was drawn from the oceans to form these huge glaciers that sea levels around the world fell by three hundred and fifty feet, and large areas of the continental shelf became dry land. This period of the Earth’s history had come to be called the Ice Age. In all, about eleven million square miles of land were covered with ice. The Ice Age terminated about fourteen thousand years ago when the ice sheets began to retreat. It took about seven thousand years for the ice to retreat to its present level. According to the passage, before the Ice Age the continental shelf was submerged in water.
阅读下面这篇短文，短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第2～5段每段选择1个正确的小标题；(2)第27～30题要求从所给的6个选项中选择4个正确选项，分别完成每个句子。 Health Education1．Health education is the part of health care that is concerned with promoting healthy behavior. A person’s behavior may be the main cause of a health problem, but it can also be the main solution. This is true for the teenager who smokes, the mother with the poorly nourished (营养)child, and the butcher (屠夫,卖肉的人)who gets a cut on his finger, By changing their beha～vior these individuals can solve and prevent many of their own problems.2．Health education does not replace other health services, but it is needed to promote the proper use of these services. One example of this is immunization (免疫) :scientists have made many vaccines (疫苗) to prevent diseases, but this achievement is of no value unless people to go receive the immunization.3．Health education encourages behavior that promotes health, prevents illness, cures disease, and contributes to recovery. The needs and interests of individuals, families, groups, organizations, and communities are at the heart of health education programs. Thus there are many opportunities for practicing health education.4．Health education is not the same thing as health information. Correct information is certainly a basic part of health education, but health education must also address the other factors that affect health behavior such as availability (可获性) of resouces, effectiveness of community leadership, social support from family members, and levels of self-help skills. Health education therefore uses a variety of methods to help people understand their own situations and choose actions that will improve their health. Health education is incomplete unless it encourages involvement and choice by the people themselves.5．Also, in health education we do not blame people if they do not behave in a healthy way. Often unhealthy behavior is not the fault of the individual. In health education we must work with families, communities, and even regional and national authorities to make sure that resources and support are available to enable each individual to lead a healthy life. Immunization helps to ______.
