听力材料：
The diamond is considered the most famous andvaluable jewel in the world.
Diamonds were made as a result of greatvolcanic heat and pressure. A volcano is amountain with a hole in the top. When a volcano isvery active it sometimes explodes and causes greatdamage.
Diamonds were pushed towards the surface of the earth-millions of years ago-by a number ofgreat volcanic explosions. It is in the narrow volcanic pipes that diamonds are found.They are also found among the sand and stones of certain riverbeds, and in a few places onthe floor of the sea, for they were washed down the mountainsides by the rain.
Diamonds are very rare. There are not many diamond pipes or diamond-producing rivers inthe world. During the last century, adventurers from Europe went to Brazil, because they hadheard that there were diamonds in the River Amazon. Most of these early diamond minersdied of illness or were lost forever in the great forests. But some returned home rich.
The earliest known diamonds were found in India many centuries ago. The most recent andexciting discoveries have been made in Eastern Russia. But most of the world's diamonds nowcome from the Congo, from Tanzania-which has the largest diamond mine in the world-andfrom South Africa.
Questions 29 to 32 are based on the passage you have just heard.
29. What does the speaker say about diamonds?
正确答案：B
解析：短文说，钻石是火山热和压力的产物。所以B正确。选项都与钻石的情况有关，可猜测题目的内容。答案中的heat and pressure是文中的原词。重要信息往往不止出现一次，后文中的great volcanicexplosions再次强调成因。
30. Where can diamonds be found?
正确答案：C
解析：短文说，钻石是在狭窄的火山筒被发现的。所以C正确。选项为地点，可预测考查的是钻石的出处。注意听原文中的地点，做好笔记。
31. What happened to most of the adventurers from Europe?
正确答案：A
解析：听到文中提到大多数早期钻矿工人died或lost时就应该可以推断出“他们没有能够带着梦寐以求的钻石回到家乡”，即A。选项描述的是They的命运。仔细听音，即可准确作答。D指的是some的命运，但content和millionaires没有依据。
32. According to the speaker, in which country were the earliest known diamonds found?
正确答案：C
解析：短文说，最早的已知钻石于几个世纪前在印度被发现。所以C正确。选项都是国家或地区的名称，猜测题目可能问地点。边听边做笔记，把听到的国家或地区所出现的情况和各选项一一对应，即可准确作答。
