二、阅读理解
Forests can be divided into different types according to their climate and location. The most common types are tropical, boreal and temperate.
Tropical rainforests (热带雨林) are located near the equator (赤道). They are hot and wet. Although they cover only a tenth of the earth's surface, they are home to about half of all species. The biggest is the Amazon Rainforest in South America. It is often called the "lungs of the earth" because the plants there produce a lot of oxygen. You'll find monkeys, frogs, jaguars (美洲豹) and many other animals there.
Boreal forests (北方针叶林) are found in the north. These forests are cold. Many animals live there and have adapted to the cold climate by growing thick fur. The Dancing Forest is a strange and beautiful boreal forest in Russia. Its name comes from the twisted (弯曲的) trunks of its trees. The pine trees there have leaves shaped like needles (针).
Temperate forests (温带森林) are found all over the world. They are hot or cool at different times of the year. There are some temperate forests in the Jiuzhaigou Valley in Sichuan, for example. Many types of trees grow there, like maples and birches (白桦树). Their leaves change colour with the seasons and fall off the trees when the weather gets cool. As the weather warms up, the trees grow new leaves.

答案：1. B
2. D
3. A
4. D
2. D
3. A
4. D
解析：
1. 根据第二段“It is often called the 'lungs of the earth' because the plants there produce a lot of oxygen.”可知亚马逊雨林被称为“地球之肺”的原因是那里的植物产生大量氧气，直接对应选项B。
2. 依据第四段“Temperate forests (温带森林) are found all over the world.”明确表明温带森林分布在世界各地，所以选D。
3. 从第三段“The pine trees there have leaves shaped like needles (针).”可知北方针叶林有针状叶的树，所以对针状叶树感兴趣的Amy可能去北方针叶林，选A。
4. 由第二段“Tropical rainforests (热带雨林) are located near the equator (赤道). They are hot and wet.”可知热带雨林温度高；第三段“Boreal forests (北方针叶林) are found in the north. These forests are cold.”可知北方针叶林寒冷；第四段“Temperate forests (温带森林) are found all over the world. They are hot or cool at different times of the year.”可知温带森林温度处于热带雨林和北方针叶林之间，所以温度从高到低是热带雨林＞温带森林＞北方针叶林，选D。
