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(物種).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（氮）. If certain species should become extinct, Dr.Duane Kraemar, a professor in Texas A&M University 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.”

1.The aim of “Noah’s Ark” project is to________.

A. make efforts to clone the endangered pandas

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nuclear of one animal to another

2.The underlined word groundbreaking can be interpreted as __________.

3.The best title for the passage may be ______.

A. China’s Success in Panda Cloning

B. The First Cloned Panda in the World

C. Exploring the Possibility to Clone Pandas

D. China---the Native Place of Pandas Forever

4.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 species will probably die out in a century

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving (鋪砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.

Human activity is not responsible for all water shortages (短缺)．Drier climates are of course more likely to have droughts (干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.

Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.

You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗機(jī)) only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

1.Which of the following is most likely to lead to less groundwater?

A. Using river water.

B. Paving parking lots.

C. Throwing batteries away.

D. Throwing rubbish into lakes.

2.What can be inferred from the text?

A．It takes a lot of effort to meet our water needs.

B．All water shortages are due to human behavior.

C．There is much we can do to reduce family size.

D．The average family in America makes proper use of water.

3.The last paragraph is intended to ________.

A. show us how to fix leaks at home

B. tell us how to run a dishwasher

C. suggest what we do to save water at home

D. prove what drinking glass is best for us

4.The text is mainly about ________.

A. why paving roads reduces our water

B. how human activity affects our water supply

C. why droughts occur more in dry climates

D. how much we depend on water to live

Michael Jordon is the greatest basketball player of all time. Once he was making a television commercial (廣告). All Michael needed to do in the advertisement was to miss a shot.

For Michael, this was difficult. He had conditioned himself to succeed whenever he was throwing the ball. Every time he threw a basketball, it went in. Every time he tried to miss a shot, he failed. In total, it took him over 20 attempts (嘗試) before he missed a shot.

For Michael, success is a strong habit. He had formed a habit that was so strong that it took him a lot of time to break it and “fail”.?

Just like drinking, smoking and collecting things, success is also a habit. The only thing is, it is much more effective!

Like all habits, once it is established (建立), it is difficult to break.?

Many people think that success is difficult to maintain (維持). They feel that it will be hard work and will need too much action and focus. The truth is that it is simply a habit, and as easy to maintain as any other habit.

Spend some time making success a habit in your life. Once you have developed it, it is not something you will want to change again. Then, the only thing you will fail at is failing.

1.Why did Jordan attempt 20 times before he missed a shot in the advertisement?

A. Because he didn’t work hard enough.

B. Because he was not careful enough.

C. Because he was too tired.

D. Because success was a strong habit for him.

2.What do many people wrongly think of success?

A. They think it is easy to maintain.

B. They think it needs too much action and focus.

C. They think it is impossible to establish the habit of success.

D. They think it doesn’t require too much work.
