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.” 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 |
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 |
The best title for the passage may be _______.

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self- respect? The collection of happiness actions broadly categorized as "honor" help you create this life of good feelings．Here's an example to show how honorable actions create happiness．
Say a store clerk fails to charge us for an item．If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky excitement．Later we might tell our family or friends about our good fortune．On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty．We would leave the store with a quiet sense of honor that we might never share with another soul．
Then, what is it to do with our sense of happiness?
In the first case, where we don't tell the clerk, a couple of things would happen．Deep down inside we would know ourselves as a type of thief．In the process, we would lose some peace of mind and self-respect．We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends．We damage our own reputations by telling others．In contrast, bringing the error to the clerk's attention causes different things to happen．Immediately the clerk knows us to be honorable．Upon leaving the store, we feel honorable and our self-respect is increased． Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility．
There is a beautiful positive cycle that is created by living a life of honorable actions．Honorable thoughts lead to honorable actions．Honorable actions lead us to a happier existence．And it's easy to think and act honorably again when we're happy．While the positive cycle can be difficult to start, once it's started, it's easy to continue．Keeping on doing good deeds brings us peace of mind, which is important for our happiness．According to the passage, the positive action in the example contributes to our_________．
| A．self-respect | B．financial rewards |
| C．advertising ability | D．friendly relationship |
The phrase "bringing the error to the clerk's attention" （in para．5） means___．
| A．telling the truth to the clerk |
| B．offering advice to the clerk |
| C．asking the clerk to be more attentive |
| D．reminding the clerk of the charged item |
How will we feel if we let the clerk know her mistake?
| A．We'll be very excited． | B．We'll feel unfortunate． |
| C．We'll have a sense of honor． | D．We'll feel sorry for the clerk． |
Which of the following can be the best title of this passage．*
| A．How to Live Truthfully |
| B．Importance of Peacefulness |
| C．Ways of Gaining Self-respect |
| D．Happiness through Honorable Actions |
Will it matter if you don't have your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had different kinds of breakfasts.
The rules show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit , eggs, bread and milk before going to school ,he or she will learn more quickly and listen more carefully in class.
The result is opposite to what some people think. Having no breakfast will not help them lose weight. This is because they are so hungry at noon that eat too much for lunch. They will gain weight instead of losing it. You will lose weight if you reduce your other meals.During the test, the people were given _________.

When you put down your pens at the end of the college entrance exam, 12 hard years of study will have come to an end. Forget your studies for a while. It's time to enjoy yourselves!
There are many ways to celebrate this special month of graduation. You can have photos taken with your classmates and teachers, or dine out together and exchange gifts.
High school students in Western countries such as the United States and Canada usually have a prom to mark their graduation. It's to mark the time kids turn into young men and women. After the prom, teenagers either go to college or find a job. It means they are no longer as dependent on their parents as they were before.
At the prom, boys usually dress in dinner jackets and bow ties, though many different types of formal clothes are worn. Traditionally, girls give boys matching boutonnieres (a small collection of flowers they pin to their jackets). Girls traditionally wear formal dresses, or dress to shock or be noticed, in shiny or brightly colored materials.
Common prom activities include dining, dancing, the crowning (加冠) of a prom king and queen, and just talking to friends. In some cases, high school students collect funds for their class prom through the four years of their high school.
High schools in or near large cities may rent ballrooms at expensive hotels or, to be unusual, on a pleasure cruise boat.
But often costs are cut by simply using the school gym. Students make a lot of effort to decorate the gym to make the event special. The music played at the prom will be the most popular kinds, like rock and hip-hop.
The students elect the Prom Queen. She is partnered with a Prom King who is elected similarly. These are great honors that the pair takes very seriously. The two dance with each other to celebrate their election.
Sometimes teachers and parents also go to the prom. But others like to go with friends, to whom they are soon going to be saying goodbye.

Why do people buy art? To answer this question, ask yourself what your reasons are for thinking of getting a piece of art. An artwork can cost a large amount of money, but if it meets your needs, it’s worth every penny.
People buy art for many reasons. Many people buy an artwork simply because they like it, even if it is by an unknown artist. Art, as long as you enjoy it, is never a waste of money.
Art is for enjoyment. Art is meant to be shown. Don’t ever feel pressured into buying something you won’t enjoy looking at day after day, no matter what other people may say. Don’t buy something that doesn’t attract you just because it is trendy, or because the artist is famous, or because you have been advised that the artwork will make a good investment. If you don’t like the artwork at all, don’t buy it!
Art improves your environment. Have you ever noticed that all beautiful homes have art as an integral（必需的） part of the decoration? Art lends life and color to otherwise plain and ordinary walls. A well thought--out art collection will help create a unique atmosphere in your home and make it more attractive.
Art makes a statement. The kind of art you surround yourself with says much about your personality tastes and values. Art truly is a mirror of the soul.
Art enriches your life. Love--even the love of a work of art--contributes to healthier living and a longer lifespan (寿命). Art should enrich your life. Otherwise, why do you spend precious time and resources on it?
