Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws(爪)on its wings when young .They build their homes about 4.6m above the river ,an important feature(特征)for the safety of the young. It is called the hoatzin.
In appearance，the birds of both sexes look very much alike with brown on the back and cream and red on the underside .The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.
Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip .Using these four claws ,together with the beak(喙),they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.
During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.What is the text mainly about?

To become a doctor in the United States, students usually attend four years of medical school after they complete college. Then these young doctors work in hospitals for several years to complete a training program called a residency(住院医生实习期).
These medical residents provide hospitals with needed services in return for not much pay. They work under the supervision(管理) of medical professors and more experienced doctors. Medical residents treat patients . they carry out tests. They perform operations. They complete records. In hospitals with few nurses, residents also do work formerly done by nurses. Some medical residents work one-hundred or more hours in a single week. They often work for more than thirty-six hours at a time before they can rest.
Critics (批评家) of this system say medical residents work too long and do not get enough res. They say these young doctors may be too tired to perform their medical duties effectively. Now, the government will limit the number of hours of work that residents can work. Most doctors in training will be limited to eighty-four hours of work each week. They will have work periods of no more than twenty-four hours at one time. They will have ten hours of rest between work periods.
Medical residents will have one day each week when they do not have to work. Any work they accept outside their hospitals will be limited．Experienced doctors and medical professors will closely supervise the residents to make sure they are not too tired to work.
Many medical residents welcomed the work limits. Others, however, said the new policy may interfere with patient care and their own medical education.If a first –year college student in America wants to be a doctor, he has to wait for ___.

Microsoft founder Bill Gates said that he planned to give away almost all of his vast fortune , largely to the cause of global health , during the course of his lifetime . With an estimated（估计）worth of more than $ 40 billion , according to Forbes , the project will be no small feat （功绩）for Gates .

Gates , was the head of the local Planned Parenthood , and his mother , Mary , volunteered for the United Way .

Reading to dogs is an unusual way to help children improve their literacy skills （读写能力）With their shining brown eyes, wagging tails, and unconditional love, dogs can provide the nonjudgmental listeners needed for a beginning reader to gain confidence （自信心） , according to Intermountain Therapy Animals (ITA) in Salt Lake City. The group says it is the first program in the country to use dogs to help develop literacy in children, with the introduction of Reading Education Assistance Dogs (READ).
The Salt Lake City Public Library is sold on the idea. “Literacy specialists admit that children who read below the level of their fellow pupils are often afraid of reading aloud in a group, often have lower self-respect, and regard reading as a headache,” said Lisa Myron, manager of the children’s department.
Last November the two groups started “Dog Day Afternoon” in the children’s department of the main library. About 25 children attended each of the four Saturday-afternoon classes, reading for half an hour. Those who attended three of the four classes received a “pawgraphed” book at the last class.
The program was so successful that the library plans to repeat it in April, according to Dana Thumpowsky, public relations manager. What is mainly discussed in the text?
| A．Children’s reading difficulties. | B．Advantages of raising dogs. |
| C．Service in a public library. | D．A special reading program. |
Specialists use dogs to listen to children reading because they think _______.
| A．dogs are young children’s best friends |
| B．children can play with dogs while reading |
| C．dogs can provide encouragement for shy children |

By saying “The Salt Lake City Public Library is sold on the idea”, the writer means the library_______.
| A．uses dogs to attract children | B．accepts the idea put forward by ITA |
| C．has opened a children's department | D．has decided to train some dogs |
A “pawgraphed” book is most probably _______.
| A．a book used in Saturday classes | B．a book written by the children |
| C．a prize for the children | D．a gift from parent |
Mr. Briggs got a job with an insurance company(保险公司) after he left school and went around visiting people in their homes to sell them life insurance. One day, after he had been working for the company for about a year, the insurance manager sent for him and said, “Mr. Briggs, I have been looking at your record as a salesman with our company, and there is one thing that surprises me about it. Why have you been selling insurance only to people over 95 years old, and why have you been giving them such generous（宽厚的）conditions? You’ll ruin our company if you go on like that.”
“Oh, no, sir,” answered Mr. Briggs at once, “Before I started work, I looked at the figures(数字) for deaths in this country during the past ten years, and I can tell you that few people die at the age of 95.” Before he worked in an insurance company, what was Mr. Briggs?______.

Bean and other seed shoots are also known as sprouts (新芽). The dry bean seeds contain a store of nutrients just waiting to be released when they sprout. Under the right conditions they will germinate (发芽)。 As they grow, the food value of the seeds is multiplied into vitamins, minerals (矿物质) and other nutrients. This happens almost overnight!
It is easy to grow your own sprouts, but you need to buy your seeds from supermarkets or health food stores. Seeds for planting in the garden are often powdered with chemicals, so when becoming sprouts they are not safe to eat.
Try growing sprouts from a variety of beans and seeds. You will find different sprouts at different stages. Bean sprouts are best when they are about three centimeters long. Wheat and sunflower sprouts taste best when the sprouts and the seeds are of the same length. If the sunflower sprout is too long it leaves a funny stinging feeling in the throat after eating. Alfalfa sprouts are best when their small leaves are well developed. Pea and soybean sprouts are good long or short.
If you leave your sprouts in filtered sunlight for a few hours, the leaves will turn green as chlorophyll (叶绿素) is added. Eating sprouts with green leaves benefits your blood, cells, and the digestive system. Which of the following sprouts taste good whether they are long or short?
| A．Soybean sprouts | B．Sunflower sprouts |
| C．Alfalfa sprouts | D．Wheat sprouts |
As sprouts grow, the food value of the seeds will_____.
| A．increase | B．decrease | C．remain the same | D．lose |
From the passage we know that______.
| A．Long sunflower sprouts taste better than short ones |
| B．Eating too long sunflower sprouts will make you feel uncomfortable in the throat |
| C．Eating sprouts with green leaves will be harmful to your health |
