You probably know about the Titanic， but it was actually just one of three state-of-the art(最先进的)ocean ships back in the day． The Olympic class ships were built by the Harland & Wolff ship makers in Northern Ireland for the White Star Line company． The Olympic class included the Olympic， the Britannic and the Titanic． What you may not know is that the Titanic wasn't even the flagship of this class． All in all， the Olympic class ships were marvels of sea engineering，but they seemed cursed to suffer disastrous fates． The Olympic launched first in 1910， followed by the Titanic in 1911， and lastly the Britannic in 1914． The ships had nine decks， and White Star Line decided to focus on marking them the most luxurious ships on the water． Stretching 269.13meters， the Olympic class ship were wonders of naval technology， and everyone thought that they would continue to be so for quite some time． However， all suffered terrible accidents on the open seas． The Olympic got wrecked before the Titanic did， but it was the only one survive and maintain a successful career of 24years． The Titanic was the first to sink after famously hitting a huge iceberg in 1912． Following this disaster， the Britannic hit a naval mine in 1916 and subsequently sank as well． Each ship was coal-powered by several boilers constantly kept running by exhausted crews below deck． Most recognizable of the ship designs are the ship's smoke stacks， but the fourth stack was actually just artistic in nature and served no functional purpose． While two of these ships sank， they were all designed with double hulls(船体)believed to make them "unsinkable"， perhaps a mistaken idea that led to the Titanic's and the Britannic's tragic end． The Olympic suffered two crashes with other ships and went on to serve as a hospital ship and troop transport in World War I． Eventually， she was taken out of service in 1935， ending the era of the luxurious Olympic class ocean liners．(1)Which of the following statements is TRUE about the three Olympic class ships？___A． They performed marvelously on the sea．B． They could all break the ice in their way．C． They all experienced terrible misfortunes．D． They were models of modern engineering．(2)What did White Star line have in mind when it purchased the three ships？___A． Their capacity of sailing across all waters．B． The utmost comfort passengers could enjoy．C． Their ability to survive disasters of any kind．D． The long voyages they were able to undertake．(3)What might have led to the tragic end of the Titanic and the Britannic？___A． Their unscientific designsB． Their captains' misjudgmentC． The assumption that they were built with the latest technologyD． The belief that they could never sink with a double-layer body(4)In the end the ship Olympic___．A． was used to carry troopsB． was sunk in World War IC． was converted into a hospital shipD． was retired after her naval service

Doctors are to begin a trial of a drug treatment that could double the time transplanted organs survive in the body. The 20-minute procedure effectively coats donor organs in a protective shield that stops them being rejected by the patient’s immune system. The treatment is expected to prolong the time that organs remain healthy in patients’ bodies and also increase their shelf-life (保存期限), so they can be stored for longer or transported further before being used. If the treatment works, it could ease the burden on organ transplant services, which face an increasing gap between the supply and demand for donor organs. People who receive transplants must take drugs to suppress their immune systems, but the body still reacts enough to cause transplants to fail sooner than they should. A healthy transplanted kidney lasts on average only 10 years, around one third of the time it should last. Organs such as hearts and livers fail even sooner. The consequence is that patients who have had one donor organ often need another. The new treatment, developed by researchers at King’s College London, is based on the defense mechanism healthy organs use to shield themselves from the immune system. Studies suggest the procedure could extend the life of an implanted kidney by around seven years. The scientists believe the treatment will also extend the shelf-life of donor organs, increasing the time they survive outside the body from no more than 24 hours to several days. This could reduce wastage and double the number of organs that work properly once they are transplanted, doctors said. In early tests, only a fifth of organs worked properly after being stored on ice for 16 hours, compared with 50% of those treated with mirococept (药物：米罗西普). A recent pilot study of the treatment on 16 patients found it was safe to use. Patients who receive donated organs treated with mirococept will still need to take drugs to suppress their immune systems, but doctors said an aim of their research was to see if the use of current drugs, which can increase a patient’s risk of cancer, can be reduced. 1 What is one of the purposes of the drug treatment mentioned in the passage? A To make a big profit from the new drug. B To reduce the risk of operations. C To prolong the shelf-life of organs. D To help patients save money. 2 According to the passage, what should the people who receive transplants do? A They need to spend a large fortune on their operations. B They have to take drugs to make the transplants effective. C They need to receive another transplant every ten years. D They have to appreciate the donors all their life. 3 Why do patients treated with the old treatment often need another donor organ? A Because they are painful after transplants. B Because drugs can ease the burden of organs. C Because the body still reacts enough to cause transplants to fail. D Because the donor organs will fail in a very short time. 4 What do we know about the new drug treatment? A It is developed by researchers in US. B It can extend the life of implanted organs. C It is independent of defense mechanism. D It can improve patients’ health. 5 What can we learn from the recent pilot study of the treatment? A The treatment can be used widely someday. B The treatment will destroy the immune system. C The current drug can increase a patient’s risk of cancer. D The result of the study doesn’t satisfy the researchers.

Dr.William Farber，a forward-thinking veterinarian，is not one to be swayed by the skepticism of his peers.After performing acupuncture on a rabbit，he asserts， "I am not crazy，" and instead considers himself to be "ahead of my time." Despite occasional ridicule from coworkers due to his unconventional methods，Farber is confident in the effectiveness of his approach. Farber，an alumnus of Colorado State University，initially followed a more traditional veterinary path.His interest in alternative treatments was piqued 20 years ago when he experienced severe back pain.After finding little relief from muscle-relaxing drugs，he turned to acupuncture —an ancient Chinese therapeutic practice —and was pleasantly surprised by the improvement he experienced after just a few sessions.This personal success inspired him to explore these techniques further，leading him to integrate them into his veterinary practice after a couple of years of study. Farber's holistic approach to veterinary medicine，which combines traditional Western treatments with acupuncture，chiropractic，and herbal medicine，has yielded positive outcomes for his patients.Leigh Tindale's dog，Charlie，who suffered from a serious heart condition，was given an additional five months of life thanks to Farber's treatments，which significantly alleviated Charlie's suffering.Similarly，Priscilla Dewing noticed that her horse，Nappy，enjoyed improved mobility and comfort after receiving a chiropractic adjustment. Farber is optimistic about the future of holistic veterinary medicine，and the growth in membership of the American Holistic Veterinary Medical Association —from 30 in 1982 to over 700 today —suggests that his optimism may be well-founded.He expresses his commitment to his work，saying， "Sometimes it surprises me that it works so well.I will do anything to help an animal.That's my job." His dedication to finding the most effective treatments for animals，whether traditional or holistic，underscores his commitment to his profession and the well-being of the animals he treats.（1）What do some of Farber's coworkers think of him？ ____ A.He's odd.B.He's strict.C.He's brave.D.He's rude.（2）Why did Farber decide to try acupuncture on pets？ ____ A.He was trained in it at university.B.He was inspired by another veterinarian.C.He benefited from it as a patient.D.He wanted to save money for pet owners.（3）What does paragraph 3 mainly talk about？ ____ A.Steps of a chiropractic treatment.B.The complexity of veterinarians' work.C.Examples of rare animal diseases.D.The effectiveness of holistic medicine.（4）Why does the author mention the American Holistic Veterinary Medical Association？ ____ A.To prove Farber's point.B.To emphasize its importance.C.To praise veterinarians.D.To advocate animal protection.
