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 Cuangxi 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.

Paleoanthropologist 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.”

1.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

2.The underlined word “variation” in para 6 means .

A. fall B. change C. increase D. decrease

3.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

The rain had continued for a week and the flood had created a big river which were running by Nancy Brown’s farm. As she tried to gather her cows to a higher ground, she slipped and hit her head on a fallen tree trunk. The fall made her unconscious(昏迷) for a moment or two. When she came to, Lizzie, one of her oldest and favorite cows, was licking(舔) her face.

At that time, the water level on the farm was still rising. Nancy gathered all her strength to get up and began walking slowly with Lizzie. The rain had become much heavier, and the water in the field was now waist high. Nancy’s pace got slower and slower because she felt a great pain in her head. Finally, all she could do was to throw her arm around Lizzie’s neck and try to hang on. About 20 minutes later, Lizzie managed to pull herself and Nancy out of the rising water and onto a bit of high land, which seemed like a small island in the middle of a lake of white water.

Even though it was about noon, the sky was so dark and the rain and lightning was so bad that it took rescuers more than two hours to discover Nancy. A man from a helicopter(直升飞机) lowered a rope, but Nancy couldn’t catch it. A moment later, two men landed on the small island from a ladder in the helicopter. They raised her into the helicopter and took her to the school gym, where the Red Cross had set up an emergency shelter.

When the flood disappeared two days later, Nancy immediately went back to the “island.” Lizzie was gone. She was one of 19 cows that Nancy had lost in the flood. “I owe my life to her,” said Nancy with tears.

1.What did Nancy try to do before she fell over?

A. Measure the depth of the river

B. Look for a fallen tree trunk

C. Protect her cows from being drowned

D. Run away from the flooded farm

2.We know from the second paragraph that______.

A. Nancy was very weak after waking up.

B. There was a small island in the farm.

C. Lizzie put Nancy on her back and carried her.

D. Lizzie was killed by the flood.

3.The following are true according to the passage except_____.

A. It took Lizzie and Nancy about 20 minutes to get to safety.

B. It was raining harder when Nancy managed to get up.

C. The bad weather made it difficult for rescuers to find Nancy.

D. Nancy took hold of the rope and climbed into the helicopter.

4.What did the local people do to help those in the flooded area according to the passage?

A. They put up shelter for them in a school.

B. They used helicopters to help carry cows.

C. They helped farmers gather their cows.

D. They set up an organization called Red Cross.

Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably, mosquitoes can do more than cause an itchy(发痒的)wound. Some mosquitoes spread several serious diseases, including Dengue, yellow fever and malaria.

Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.

Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.

But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains, use three senses to find a blood meal.

Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.

Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr Dickinson said, at first, the mosquitoes showed no interest in the objects at all.

“What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2, they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点).”

This suggested to the researchers that a mosquito’s sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal, they also follow visual signals.

1.What do mosquitoes mainly use to find their targets?

A. Sense of smell. B. Sense of touch.

C. Sense of sight. D. Smart brains.

2.The first response of the mosquitoes to the objects in the experiment is .

A. to fly to the dark ones

A. Don’t let them see us.

B. Use dark objects to stop them.

C. Make them fly back and forth for hours.

D. Attract them to objects full of carbon dioxide gas.

4.What can be the best title for the text?

A. How Do Mosquitoes Survive?

B. Why Do Mosquitoes Need Blood?

C. How Do Mosquitoes Choose to Bite You?

D. Why Do Mosquitoes Attack the Human Being?

One is not born able to speak a language. One is born able to make a noise. I have heard babies cry in America and in China. I can’t tell any difference. But when I hear someone from America speak English and hear someone speak Chinese, I can tell you there are a lot of differences.

I believe a common(普遍的) problem with Chinese students’ learning English is that they were not taught to think in English. They have an idea spoken in English and want to translate the idea into Chinese, then they think in Chinese of the proper reply and translate it into English. After along period of speaking the language, one begins to think in the foreign language naturally. You will learn faster if you begin to think in English at the very beginning of your study. Many students ask me: What can I do to improve my spoken English?

My reply is: The more English you speak, the better English you will speak. There are many things you can do to improve your spoken English. Of course, the best way is to live where English is spoken as a language of the country.

1.The cries of American and Chinese babies are _______.

A. teachers never gave the students the way of learning English

B. some teachers didn’t teach students to think in English

C. students didn’t remember the way teachers taught them

D. teachers didn’t want their students to think in English

3.The underlined word “they” (in Paragraph 2) refers to “_____”.

A. English students B. Chinese teachers
