D
With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
69. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A. available panda eggs                     B. host animals
C. qualified researchers                     D. enough money
70. The best title for the passage may be _______.
A. China’s Success in Pandas Cloning   
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas
D. China —the Native Place of Pandas Forever
71. From the passage we know that _______.
A. Kraemer and his team have succeeded in cloning a dog
B. scientists try to implant a panda’s egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand of species will probably die out in a century

A

We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters (爬行生物) like to do the same thing!

Winter is the time when bugs (虫子) invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.

Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There’re different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn’t when the temperature drops.

They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there’s each day. They use that to tell them when to shut down. Bugs are cold-blooded, meaning that their inside temperature is the same as the outside. They can’t move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.

They’re looking for protection. These guys have been doing this for 300 million years, so they don’t really know they’re coming into your house. The home is a recent event in terms of their evolutionary behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don’t care about humans.

56. What is the purpose of the first paragraph?

   A. To point out that humans like to stay at home in winter.

   B. To mean that humans and bugs have the same living habits.

   C. To mean that bugs will invade the house for their winter.

   D. To put forward the idea that bugs are not welcome in winter.

57. According to the text, what is diapause?

   A. It is the same as the animals’ hibernation.

   B. It often appears in warm areas all the year.

   C. It is done to keep bugs active in winter.

   D. It is a deep sleep similar to hibernation.

58. What often decides bugs’ diapause?

   A. The lower local temperatures.           B. The amounts of sunlight.

   C. Kinds of environmental signals.         D. The insects’ inside temperature.

59. According to the text, bugs invade humans’ homes to ______.

   A. attack humans                                 B. look for enough food

   C. seek for protection                           D. show their evolutionary results

60. What would be the best title for the text?

What is the hottest topic at your school? In Hangzhou Yongjin Middle School, it's money. The school ran an activity called" making a living "recently. About 800 Junior1 and Junior 2 students were divided into 112 teams .They went out to make money by selling things.
What did they choose to sell? Some sold newspapers; some chose bottled water ;some sold environmentally friendly shopping bags and bamboo baskets.
Hu Qi's team decided to sell educational books in front of the Children Activity Center. There are always many parents around there and they thought parents would like to spend money for their children, especially on books .But unfortunately, they came across urban management officers(城管）.The officers asked them to leave.
"We played hide-and-seek (捉迷藏）with the officers for the whole morning" said Hu." Finally we gave up and moved to other places."
Wang Yongyi and her team sold ice cream in a square. They didn't meet any officers. But few people were interested in what they were selling.
