Health Gains in Developing Countries
以下图为依据描述发展中国家的期望寿命（life expectancy）和婴儿死亡率(infant mortality) 的变化情况。
说明引起变化的各种原因。
During the period from 1960 to 1990, the life expectancy of developing countries rose from 40 years to nearly 60 years, while infant mortality decreased from 200 deaths per1,000 births to around 100.
We believe that three reasons can account for this phenomenon. First, economy develops quickly in developing countries during this period, and living quality improves significantly as a result. Second, people’s health conditions also become better and better with the development of national health care system. When they become richer and richer, they care more about personal health conditions. Third, medical science also develops at a fantastic speed, and it is much safer for mothers to give birth.
We are happy to see that things are becoming better and better nowadays. We can imagine that people will live longer and the infant mortality will again fall.
在1960年至1990年，发展中国家的预期寿命从40年近60岁，而婴儿死亡率由200人死亡per1，000年出生减少到约100个。 我们认为，三个原因可以解释这一现象。首先，经济的迅速发展，发展中国家在此期间，生活质量得到改善，结果显着。第二，人们的健康状况也变得更好，并与全国医疗卫生系统的发展更好。当他们变得越来越丰富，他们关心个人的健康状况更多。三，医疗科学也以惊人的速度发展，这是很多母亲安全分娩。 我们高兴地看到，事情正在好转，现在更好。我们可以想像，人们寿命延长，婴儿死亡率将再次下降。On the one hand,_____________.

Changes in the Ownership of Houses
根据下图描述该市住房产权的变化
分析产生这些变化的原因。
From the chart, we can see clearly that in a bit city in China, state-owned houses declined from 75%in 1990 to 60% in 1995 and then to 20% in 2000, while private houses rose from 25% to 40% and then to 80% during the same period.
Two reasons, in my mind, can account for the fundamental changes in the ownership of houses. On the one hand, the housing reform is one of the most important urban economic reforms and the old system of house distribution is replaced by individual purchase of real estate. On the other hand, as the income level goes up, people want to live in larger and more comfortable houses.
Such changes have a significant impact on both individuals and the whole society. For one thing, with the deepening of the housing reform, private housing investment witnesses an unprecedented boom. For another, national urban construction undergoes sustainable development, which is of great importance to the national economy as a whole. In a word, the housing reform is beneficial to both individuals and the whole society.
从图表，我们可以清楚地看到，在有些城市，在中国，国有住房的75％下降到1990年的60％，然后在1995年至20％，2000年，而私人住宅由25％上升到40％，然后到80％，在同一时期。 有两个原因，在我看来，可以考虑在房屋所有权的根本变化。一方面，住房制度改革是一个最重要的城市经济改革和内部分配旧体制是由个人购买房地产所取代。另一方面，随着收入水平上升，人们希望生活在更大，更舒适的房子。 这种变化对个人和整个社会产生重大影响。一方面，随着住房制度改革的深化，私人住房投资证人了前所未有的繁荣。其次，国家经历了城市建设的可持续发展，这是非常重要的对整个国家经济。总之，住房制度改革有利于个人和整个社会。

Seen from the chart, it can be concluded that American students prefer to read popular novel rather than other kinds of books. Among all the books the students read now, popular novels account for 68% while unpopular novels make up 17%, technical books 8% and poem collection only 5%.
It is no wonder that popular novels have attracted such a large audience. They are written in plain language so that one can easily read them for entertainment or relaxation. Books of technology and collections of poems are less appealing in that the former is often complicated and the latter abstract.
In my own practice, I think it not advisable at all to read poplar novels. On the one hand, I spend much of my free time reading books in my specialized field-environmental protection. On the other hand, I take great delight in reading nonfiction such as history and biography so as to be wiser and more reasonable. To turn my dream into reality, I must cherish every minute of my life and work hard.
从图表来看，可以得出结论，美国的学生喜欢阅读通俗小说，而不是其他类型的书籍。在所有的书籍现在的学生阅读，通俗小说占68％，而不受欢迎的小说占17％，8％的技术书籍和诗集只有5％。 这不是什么流行的小说，吸引了大批观众，这样怀疑。他们是用普通的语言，因此可以轻松地阅读了他们的娱乐和放松。的技术和诗集出版的书籍有吸引力不大，因为前者常常很复杂，后者抽象。 在我自己的实践，我认为并不适宜杨树读小说。一方面，我用我的空闲时间看书，我的专业领域，环保上面。另一方面，我的阅读，如历史与传记纪实，从而极大高兴能够更明智合理的。要变成现实我的梦想，我要珍惜每一分钟，我的生活而努力奋斗。
