听力原文： If you've been on campus for very long, I'm certain that you've already heard about this course. You may know that last semester about fifty percent, of the Students enrolled in my course failed it. Let me explain how this came about before you jump to any conclusions. In the first place, since this is a composition class, I expect my students to follow certain rules of formality. Unfortunately, many students today dislike having to follow rules of any kind, especially those which they may feel to be unnecessary. For example, I ask that each of your papers be typed and centered on the paper correctly. I count off points for various kinds of mistakes. A misspelled word will cost you 5 points. You've lost 25 points if you've misspelled five words. If you write an incomplete sentence, you've lost 10 points. If you give me two complete sentences as one without adequate punctuation, you've lost 15 points. I do not accept late papers. You will receive a zero for any theme which you fail to submit on time. I expect you to read each assignment. To make certain that you have read the assignment, I will give you a short unannounced quiz from time to time. This class meets on Mondays, Wednesdays, and Fridays. You will have a total of six major tests throughout the semester. Your final grade will he based on an average of these major tests, the pop tests, and eight written themes. If you have any questions at any time, you can see me on Tuesdays. My office is on the second floor of this building. Your assignment for Wednesday is to read Hemingway's short story on page 55. Friday will be the last class day of this week, so you can expect to write a short in-class theme for me then. That's all for today, I'll see you on Wednesday.

China's Mineral Deposits
China's vast territory and complicated geological formations create favorable conditions for mineralization. Rich mineral deposits are found on the plains and in the mountains.
Reserves of over 50 metals and nearly 80 non-metals have been discovered, in addition to rich fuel-bearing deposits. These include rich deposits of nonferrous metal, rare-earth metal, coal and certain non-metals. The proved reserves of a number of minerals are among the richest in the world, including rare earth, coal, iron, copper, tin, lead, zinc and aluminum. The prospects for petroleum and natural gas are also bright. The abundance of minerals provides a solid material basis for the country's modernization.
Nevertheless, there are also some inadequacies. Most of the minerals are unevenly distributed and the prospects of some reserves are not clear. Insufficient reserves have been proved for some minerals: others, such as iron and copper, do not usually occur in rich veins.
The reserves of quite a number of minerals are among the largest in the world, but the per capital amount is smaller than that in many other countries.
Although China has conducted a great many preliminary surveys, the work has to be in tensified in the eastern part of the country, and it has hardly begun in many places in the west. Prospecting and exploitation are still rather backward. China has only just opened the door to its underground treasure house, where the mysteries have by no means been uncovered. With the progress in geological research and exploration, more and better minerals will be found.
Which minerals have been proved to be insufficient？
