Question

10．You know immediately that something strange is going on in the city of Rotorua．The air smells like bad eggs．Clouds of steam rise from the ground．Strange coverings of yellow，white，and red cover the rocks，which burn your hands．The ground shakes as a geyser （間歇泉） sends hot water 100 feet into the air．
Welcome to New Zealand's North Island，where the earth boils under your feet．This hot spot is part of the Ring of Fire，a circle of underwater volcanoes （火山） and earthquake areas around the Pacific Ocean．New Zealand sits above a place between two plates （huge rock s that form the surface of the earth）．As they slowly move together，the edge of one plate is pushed under the other，where it becomes molten （熔化的） rock．This molten rock heats rocks and groundwater lying above it，creating a hot area．Under Rotorua lies a huge amount of steam and hot water heated by molten rock．
Rotorua may not sound like a perfect place to live，but people who made their homes in the area managed to survive．The Maori people arrived 600 years ago and built villages around the hot springs．They used the hot water to wash and keep warm．They prepared their meals by placing baskets full of meat and vegetables into steaming pools．Today，the Maoris in traditional villages still use the heat the same way their ancestors did．
The people of Rotorua have learned to live above the boiling earth．Walkers in hot spots must stay on marked paths，or risk falling into a pool of boiling water．For safety，houses are not built in known hot areas．But sometimes the steam and hot water break through the ground in unexpected places．Imagine a geyser suddenly appearing in your front yard!

29．C 考查句意理解．This molten rock heats rocks and groundwater lying above it，creating a hot area．這種熔化的巖石加熱了在它上面的巖石和地下水，形成了一個(gè)熱點(diǎn)區(qū)域．可見(jiàn)這里的it指的是這些融化了的巖石This molten rock，所以答案選C．
30．B推理判斷題．根據(jù)句子They used the hot water to wash and keep warm．They prepared their meals by placing baskets full of meat and vegetables into steaming pools．他們用熱水洗保溫，他們把裝滿(mǎn)肉和蔬菜的籃子放在熱氣騰騰的水池里準(zhǔn)備飯菜．可見(jiàn)早期的Maoris充分地利用了溫泉，所以答案選B．
31．C 細(xì)節(jié)理解題．根據(jù)句子Walkers in hot spots must stay on marked paths，or risk falling into a pool of boiling water在熱點(diǎn)地區(qū)行走的人必須保持在標(biāo)過(guò)的路徑上，否則就有可能掉進(jìn)沸水池中．可見(jiàn)是為了避免危險(xiǎn)．所以答案選C．
