听力原文： Although people often use the phrase "the dictionary", there are many different kinds of dictionaries, some general and some specialized. General dictionaries are all-purpose dictionaries that contain a broad range of words and common usage. The first general dictionary that you used was probably a school dictionary. These dictionaries contain relatively few words and emphasize common words that you are most likely to encounter in your school years.
Later, most people acquire a college dictionary. These dictionaries have more than 150, 000 entries with detailed definitions that are sufficient for most college students as well as general users. They also separately list abbreviations, biographical and geographical names, foreign words and phrases and tables of measures. The Random House Websters College Dictionary and the American Heritage Dictionary are well-known college dictionaries.
For scholars or researchers, un abridged dictionary provides as many as 500,000 entries that have detailed definitions and extensive word histories. You will find these dictionaries primarily in libraries and they often spend several volumes. Specialized dictionaries such as the drinking water dictionary or dictionary of legal terms are also very useful for scholars or researchers.

As a result of the family planning policy, China has seen 400 million fewer births, which has resulted in 18 million fewer tons of CO2 emissions a year, Zhao said.
The UN report projected that if the global population would remain S billion by the y^ar 2050 instead of a little more than 9 billion according to medium-growth scenario, "it might result in 1 billion to 2 billion fewer tons of carbon emissions" Meanwhile, she said studies have also shown that family planning programs are more efficient in helping cut emissions, citing research by Thomas Wire of London School ot Economics that states; "Each $7 spent on basic family planning would reduce CO2 emissions by more than one ton whereas it would cost $ 13 for reduced deforestation. $ 24 to use wind technology, S 51 for solar power, $ 93 for introducing hybrid cars and $ 131 electric vehicles". She admitted that China's population program is no: without consequences, as the country is entering the aging society fast and facing the problem of gender imbalance.
