Thousands of years ago, in the south of ancient China, there lived Shennong, a man who had an ox(牛) head and human body. Seeing that local people were suffering from disease, he built ladders and houses on a high mountain to store hundreds of medical plants. To remember him, people named the place shennongjia.
The legend(传说) makes Shennongjia in Hubei an inviting place for tourists. Traveling there is a unique experience, as you can see sceneries of the four seasons from different altitudes. "When the bottom of the mountain is summer, the top is spring and while the foothill is autumn, the top is covered with ice," local people say of the special climate of Shennongjia.
Shennongjia is also home to 5,000 species of animals and plants. Many animals in danger live there, such as the golden monkey, the clouded leopard and the Asian black bear.
One interesting and mysterious thing about Shennongjia is its legend of wild men. Some people once claimed that they saw big prints or big-foot creatures. Yet so far, scientists haven’t proved it is true and some say they are just bears.
The beautiful place has recently received a new title. On July 17, 2016, Shennongjia Forestry District was added to United Nations World Heritage list as a natural site. China now has 50 world heritage sites(遗址). Second only to Italy in the world.
1. Which of the following is RIGHT about Shennong ________
A. Shennong had an ox body. B. Shennong grew medical plants for people.
C. Shennong helped the local people. D. Shennong named the place Shennongjia.
2. In Shennongjia, ________.
A. there are many medical stores along the way
B. people can experience four seasons up the mountain
C. there are 500 species of animals and plants
D. scientists have proved that there are wild men there

三. 预习自测
(一) 单项选择
1. 答案：D
解析：考查比较级的用法。句意：—这些天烟雾弥漫。太可怕了！—是的。我希望种树。树越多，空气污染越少。more后接可数名词复数形式或者不可数名词；less后接不可数名词；fewer后接可数名词复数形式。trees为可数名词复数形式，排除选项B、C； pollution为不可数名词，故用less，所以选D。
2. 答案：A
解析：句意:他们的生活条件过去很差,但现在改善了很多。考查名词辨析。condition条件; purpose意图; idea想法; subject学科。根据空前的"Their living"和空后的"was very poor in the past"可知,应该是生活条件很差,故选A。
3. 答案：B
解析：由than可知,这里用形容词的比较级。故选B。
4. 答案：D
解析：develop意为"发展"rise意为 "上升；升起"；drop意为"落下" weigh意为 "重量是……；称……的重量"。根据答语 "About 50 kilos. "可知此处询问对方的体重。故选D项。
5. 答案：C
解析：句意:丹尼尔和他的双胞胎兄弟一样高。他们身髙都是1. 75米=根据"他们身髙都是1. 75米"可知，丹尼尔和他的双胞脸兄弟一样高。as... as... . 意为"和……-样……"，符合 句意。
(二) 阅读理解
答案：1-5 CBCAC
解析：1. 推理判断题,根据"Seeing that local people were suffering from disease, he built ladders and houses on a high mountain to store hundreds of medical plants. "可知,看到当地人遭受病痛,神农就在高山上建了梯子和房屋来存放数百种药草,帮助当地人。故选C。
2. 细节理解题,根据"Traveling there is a unique experience, as you can see sceneries of the four seasons from different altitudes. "可知,人们可以在神农架体验四季变化。故选B。
3. 词义猜测题,根据"On July 17, 2016, Shennongjia Forestry District was added to United Nations World Heritage list as a natural site. "可知,2016年7月17日,神农架自然风景区被列入联合国世界遗产名录,也就是说,神农架这个美丽的地方最近拥有一个新的"称号":世界自然遗址。所以title表示"称号",故选C。
4. 细节理解题,根据"China now has 50 world heritage sites (遗址). Second only to Italy in the world. "可知,中国现在有50个世界遗产,世界上仅次于意大利,说明第一名是意大利,故选A。
5. 主旨大意题。通读全文可知,文章主要介绍神农架名字的起源、独特的气候条件及风景、动植物和关于野人的传说,最后还介绍神农架自然风景区已被列入联合国世界自然遗产名录,所以文章主要是介绍神奇的神农架,故选C。
