more and more rainforests are（ )填disappear的形容词

13题选择B 从文章第一段中此句可以得出 “Rainforests have their own perfect system for guaranteeing their own survival; the tall trees make a cover of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, dry heat and strong winds. ” 而A.B两个选项在文章第一段第一句 只是为了形容雨林的作用 15题选择B 从文章第3段 此句可以看出来 “and in some areas there may be as much as 430 inches of rain annually” annually就是每年的意思 AC两个选项 就位于这一段 仔细看一看 自己来发现什么不对吧 注意题目中关键的条件限制是"in some areas"哟

雨林因为许多不同理由而有重要意义
be of consequence有意义

B

1.clearly
2.the most popular
3.dearer
4.main

怎样保护热带雨林？

Tropical rain forests grow in warm, wet areas-Central America South Amereica, Arica, and Southeast Asia . Because it rains a lot there . With so much rain , the soil in rain forests is very dark and rich for plants to grow. More than half of the tropical plants in the world grow in rain forest. Thousands of animals live in them, too.
Rain forests make up less than 8% of the earth, but more than 50% of the plants and animals on the earth live in them. Thick plants makeit difficult to go very far into the forest. Most exploring must be done on foot, or by boat. Therefore, there are large areas that haven't been discovered
yet.
Tropical rain forests are rich for food, medicine and other useful things .
Today , sadly, rain forests are threatened by such things as acid rainfrom factory smoke emissions around the world and from farm expansion. A lot of rain forests are burned or cut down each year. The land is used for farming of for building factories. Because of the loss of rain forests , 1000 kinds of plants and animals become extinct.
Many people understand the importance of saving the rain forests. Many countries are making rain forests into national parks. Farmers are being taught how to grow crops without hurting the rain forests.
Perhaps you can do something to help protect the rain forests of the earth.
问题补充：和To strengthen environmental education and to enhance citizens' awareness of environmental protection; Establishment of an International Fund, the local benefit from the management and protection; rain forest management and protection, establishment of nature reserves; forest selective logging and reforestation; to encourage the development of protective; reduce the opportunities of immigrants and farming into the rain forest

其实两者意思差不多,主要的区别就是程度问题.
【thousands of】成千上万的

就像楼上那位说的一样,D表示动作已经结束,而题目中是说现在正在被cut和burn.cut用进行时表示动作的正在进行,burn因为是被烧,所以用被动（和前面的cut 公用一个动词are）,就是这样子.我是英语专业大二的学生,

知道上有问过的,简化一点,
Tropical rainforests are rich in food,medicine ,and other useful things.Sadly,many forests are burned or cut down each year for construction of factory farming .Because the loss of rainforest ,causing temperature changes,more than 1000 kinds of plants and animals become extinct.Maybe you can do something to help protect the Earth's rainforests .For example:
To encourage environmentally sound lifestyle around people .
Established parks to protect rainforests and wildlife.
热带雨林有丰富的食品,药品和其他有用的东西.可悲的是,许多雨林被烧毁或砍伐每年,用于建筑的工厂养殖.因为雨林的损失,引起温度变化,1000多种植物和动物灭绝.也许你可以做一些事情来帮助保护雨林的地球.比如：在种植修复受损生态系统的毁林地区.
　　为鼓励各地环境无害的生活方式的人.

不行的
be being done 是现在进行时的被动语态
热带雨林正被砍伐.

1 remain后面的动词必须是to do结构,也就是不定式结构.
2 see是及物动词,必须在后面写上宾语,但如果没有宾语,就必须是被动语态结构.
所以答案是B to be seen.明白了吗?

home
save

短文属于说明文。短文对雨林的分布，所包含的动植物的种类，它的重要性，以及它的危险状况等等做了介绍。
小题1:细节理解题。从Paragraph 1“Therearen’tany rainforests in EuropeorNorthAmerica.” 这句得知欧洲和北美没有雨林，因此排除A、D、C三个选项。
小题2:推理判断题。从Paragraph 2“Therearemanyverybeautifulbirds,insectsand reptiles .”这句中得知reptiles与鸟、昆虫并列，可以推测出它不包括这两类；而sparrow “麻雀”swallow“燕子”都是属于鸟，butterfly“蝴蝶”属于昆虫，因此这三项应排除。
小题3:综合理解题。Paragraph 4主要讲“therainforestsareindanger”，比如，面积在减少，动植物绝迹等等。A项最符合本段的中心意思。
小题4:主旨大意题。本文从雨林的重要性讲到它面临的危机，旨在告诉大家给予保护。

雨林覆盖6％的地球表面.
有雨林,在世界上许多地方,但更大的森林是在南美和东南亚-东亚.
没有任何雨林在欧洲或北美.

人类依靠雨林得以继续生存.

热带雨林是由于许多不同的原因而形成的.
