IV. EARTH SUMMIT
In 1992, more than 100 heads of state met in Rio de Janeiro, Brazil for the first international Earth Summit convened to address urgent problems of environmental protection and socio-economic development. The assembled leaders signed the Convention on Climate Change and the Convention on Biological Diversity, endorsed the Rio Declaration and the Forest Principles, and adopted Agenda 21, a 300 page plan for achieving sustainable development in the 21st century.
The Commission on Sustainable Development (CSD) was created to monitor and report on implementation of the Earth Summit agreements. It was agreed that a five year review of Earth Summit progress would be made in 1997 by the United Nations General Assembly meeting in special session. This special session of the UN General Assembly took stock of how well countries, international organizations and sectors of civil society have responded to the challenge of the Earth Summit.
III. What is World Environment Day? World Environment Day was established by the United Nations General Assembly in 1972 to raise environmental awareness and to encourage action to protect the environment.
2. - Do you know Tom bought a new car?
- I don't know, _______.
A. nor don't I care B. nor do I care
C. I don't care neither D. I don't care also
答案为B。 Not until 引导从句位于句首，后面的主句要倒装。
答案为B。句中的nor引出部分倒装结构，表示"也不"。由 so, neither, nor引导的倒装句，表示前一情况的重复出现。其中, so用于肯定句, 而 neither, nor 用在否定句中。
典型例题
- Why can't I smoke here?
- At no time _______ in the meeting-room.
A. is smoking permitted B. smoking is permitted
C. smoking is it permitted D. does smoking permit
答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时，其句中的主谓须用倒装结构。这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.
Not until the early years of the 19th century _______ what heat is.
A. man did know B. man know
C. didn't man know D. did man know
答案D. 看到Not until…的句型，我们知道为一倒装句，答案在C，D 中选一个。改写为正常语序为，Man did not know what heat is until the early years of the 19th. 现在将not提前，后面就不能再用否定了,否则意思就变了。
No sooner _______ than it began to rain heavily.
A. the game began B. has the game begun
C. did the game begin D. had the game begun
答案D. 以具有否定意义的副词放在句首时，一般采用倒装句(谓语前置)。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when等等。
注意：只有当Not only… but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语，不可用倒装结构。
Not only you but also I am fond of music.
II. About World Day for Water
The United Nations General Assembly adopted resolution A/RES/47/193 of 22 December 1992 by which 22 March of each year was declared World Day for Water, to be observed starting in 1993, in conformity with the recommendations of the United Nations Conference on Environment and Development (UNCED) contained in Chapter 18 (Fresh Water Resources) of Agenda 21.
