Hundreds of armed police have been deployed around the temple. Meanwhile，a debate about how to use the money has also broken out across the country. After discovering the treasure trove in Sri Padmanabhaswamy Temple in the southern Indian state of Kerala，the local government has assured security of the temple.
Elaborating(详述)on the security arrangements，Venugopalan Nair，Additional Director General of the Kerala Police，says the latest security devices are being used to guard the temple.

Gen. of Kerala Police，said，“We are trying to bring in the latest technology with regards to surveillance(监视)cameras，with regards to，you know digitalizing the various things which are available inside. We are keeping a constant sort of surveillance for every movement，which happens in the whole area surrounding the temple. ”
According to temple authorities，the crowd at the temple has increased steeply after news of the discovery of the treasure trove. And the Administrative Officer of the Temple says the government has initiated appropriate steps to control the curious crowds visiting the temple.

Over the last week，a seven-member team of investigators broke into five secret subterranean vaults，and discovered jewels that have been lying untouched for hundreds of years.
As estimates of the treasures' worth rise，a fierce debate is growing regarding what to do with the discovery.

(2018·江西南昌进贤一中高二月考)The discovery of an ancient giant panda skull has confirmed its bamboo diet dates back more than 2 million years and may have played a key part in its survival.
A Chinese-US research team reports its results today following studies on a fossil skull found in south China's Guangxi Zhuang Autonomous Region in 2001.
The six fossils unearthed in Jinyin Cave are dated between 2. 4 and 2 million years ago，according to the report in Proceedings of the National Academy of Sciences，an influential US journal.
Jin Changzhu，of the Chinese Academy of Sciences(CAS)and lead author of the paper，said the smaller fossil skull indicates the giant pandas were about a third smaller than today's pandas.
Researchers knew the panda reached its maximum size about 500,000 years ago，when it peaked，and then gradually became smaller.
Jin，a paleontologist(古生物学者)at the Institute of Vertebrate Paleontology and Paleoanthropology(古人类学)attached to the CAS，said the size variation was a basic rule of evolution.
“A species tends to grow bigger when it reaches the peak of its population，but becomes smaller when numbers decline，”he said.
The dental remains of the skull，which is the oldest giant panda skull ever found，are similar to today's pandas，indicating the type of teeth that could munch(津津有味地嚼)mountains of bamboo. A panda can eat up to 40kg of bamboo per day.
Paleo anthropologist Russell Ciochon，the US co-author at the University of Lowa，said the panda's focus on bamboo could have helped it survive all these years.
“Once an animal begins to rely on a common and stable food source，such as bamboo，it tends to evolve a larger body size，”he said. “As individuals of the evolving species grow bigger，they have a better chance not to be eaten by predators(肉食动物)due to their larger body size. ”
4．According to the research of the CAS，there were most pandas in the world________. A．2 million years ago
B．between 2. 4 and 2 million years ago C．500,000 years ago D．Nowadays
答案 C [细节理解题。根据第五段“Researchers knew the panda reached its maximum size about 500,000 years ago，when it peaked，and then gradually became smaller. ”可知500,000年以前的大熊猫数量是最多的。故选C。] 5．The underlined word “variation” in Para. 6 means“________”． A．fall C．increase
B．change D．decrease
答案 B [词义猜测题。根据第七段“‘A species tends to grow bigger when it reaches the peak of its population，but becomes smaller when numbers decline. ’he said. ”可知，一个物种的数量达到顶峰，它们的体型会变大，而数量减少，体型会变小。由此可知此处指的是体型的改变。故选B。] 6．From the passage，we can learn________. A．pandas began to eat bamboo 2 million years ago B．a species tends to grow smaller when numbers decline C．the giant pandas were about a third the size of today's pandas D．pandas' bamboo has played an important role in its development
答案 B [细节理解题。根据第七段“‘A species tends to grow bigger when it reaches the peak of its population，but becomes smaller when numbers decline. ’ he said. ”可知当一个物种数量减少时，这种生物的体型会变小。故选B。] Ⅱ. 完形填空
