Help or Not

Dear editor,

During last year's winter holiday, I went shopping with my grandmother. We saw several beggars. Some of them were disabled, which made me feel sad. Among them were old people, young people and even children! When I wanted to help them, my grandmother stopped me. She told me they were not worth showing mercy to because some beggars cheated people out of their money. Should I help them?

                                                                                           Yours,

                                                                                           Mary from Guangzhou

Dear Mary,

       While I understand your grandmother’s point of view, I think that just because some beggars have cheated people, this doesn’t mean you should never help any beggars.

       Showing mercy to people who are not as fortunate as us is one of the kindest things we can do. While some beggars may use dishonest means to get money, most beggars will not. Even those who use dishonest means are probably hungry for food and feel they have no choice but to cheat people. It is important to be careful for your own safety. But if you want to help, you don’t necessarily have to give it to beggars in the street.

       Another way you can help is by donating money to the China Charity Federation. Visit its website at: www. china charity. cn.net.

18.From the grandmother’s point of view, we can learn that ________.

A. she has never helped the beggars.    

B. she believes not all beggars are honest

C. she has surely been cheated by some beggars  

D. she shows no pity for the poor

19. Mary felt sad for _______.

       A. her grandmother                                                 B. the disabled beggars 

C. the old people                                              D. herself

20. The editor suggests that Mary should _______.

       A. have her own mind                                      B. follow her grandmother

       C. do something for those unfortunate                D. help the China Charity Federation

21. The underlined word “donating” probably means _______.

       A. give out of kindness                                     B. put into a business

C. earn through an organization                         D. give in return for some kindness

An Australian man who has been donating his extremely rare kind of blood for 56 years has saved the lives of more than two million babies.

James Harrison has an antibody in his plasma that stops babies dying from Rhesus disease, a form of severe anaemia. He has enabled countless mothers to give birth to healthy babies, including his own daughter, Tracey, who had a healthy son thanks to her father's blood.

Mr. Harrison has been giving blood every few weeks since he was 18 years old and has now racked up a total of 984 donations. When he started donating, his blood was deemed so special that his life was insured for one million Australian dollars.

He was also nicknamed the “man with the golden arm” or the “man in two million”. He said: “I've never thought about stopping. Never.” He made a pledge to be a donor aged 14 after undergoing major chest surgery in which he needed 13 litres of blood. “I was in hospital for three months,” he said. “The blood I received saved my life so I made a pledge to give blood when I was 18.”

Just after he started donating he was found to have the rare and life-saving antibody in his blood. At the time, thousands of babies in Australia were dying each year of Rhesus disease. Other newborns suffered permanent brain damage because of the condition. The disease creates an incompatibility between the mother's blood and her unborn baby's blood. It stems from one having Rh-positive blood and the other Rh-negative.

His blood has since led to the development of a vaccine called Anti-D. After his blood type was discovered, Mr. Harrison volunteered to undergo a series of tests to help develop the Anti-D vaccine. “They insured me for a million dollars so I knew my wife Barbara would be taken care of,” he said. “I wasn't scared. I was glad to help. I had to sign every form going and basically sign my life away.”

Mr. Harrison is Rh-negative and was given injections of Rh-positive blood. It was found his plasma could treat the condition and since then it has been given to hundreds of thousands of women. It has also been given to babies after they are born to stop them developing the disease.

It is estimated he has helped save 2.2 million babies so far. Mr. Harrison is still donating every few weeks now.

How old is James Harrison?

A. 56           B. 70           C. 74           D. 78

What does the underlined phrase “two million” refer to?

A. babies           B. mothers      C. dollars          D. all of the above

   Why did James decide to donate his blood? Because _____.

    A. his daughter asked him to help her son

    B. he has a golden arm worth a million dollars

    C. a vaccine called Anti-D is to be developed

    D. someone else’s blood saved his life

The sentence “The disease creates an incompatibility between the mother's blood and her unborn baby's blood” (underlined in Paragraph 5) suggests that _____.

    A. babies suffer permanent brain damage before born

    B. the mother and the baby have different types of blood

    C. Rhesus disease contributes to permanent brain damage

    D. all the patients have a rare antibody in their blood

   What can we infer from the sixth paragraph?

    A. Some of the tests to develop the vaccine are dangerous.

    B. His wife Barbara needed to be taken care of badly then.

    C. Mr. Harrison was glad to help develop a new vaccine.

    D. His blood type was accidentally discovered after tests.

The cultural and natural values of Kakadu National Park were recognized internationally when the Park was placed on the UNESCO World Heritage List. This is an international register of properties that are recognized as having outstanding cultural or natural values of international significance. Kakadu is the largest national park in Australia and is the second largest national park in the world. Kakadu is a biological wonderland, which is almost 8,000 square miles. The wildlife in Kakadu National Park includes over 280 kinds of birds, 60 kinds of native mammals, 55 kinds of freshwater fish, thousands of insects, and many reptiles(爬行動物), the most famous of which is the salt-water crocodile. All life in the park depends on water.

Kakadu is not only home to the wildlife but the area is also famous for the longest continuous human culture that exists in the world. Aborigines(土著) have been living in this area for at least 40,000 years. The descendants(后裔) of these First Australians still live in Kakadu today. Kakadu contains one of the longest continuous records of rock art in the world, with around 5,000 paintings, with rock sites dating back 25,000 years. More than 1,000 sites have been recorded. Kakadu has been given double World Heritage status by the United Nations. It is one of only 17 of the 469 World heritage Areas listed for both natural and cultural values.

It is Australia’s largest national park, but it isn’t just the size that surprises visitors — it is the sense of something very old and grand. Creation of the 500 km escarpment(懸崖) began 2,000 million years ago. Today those gorges are filled with rainforests, washed by waterfalls.

   Kakadu is one of the world’s special places. It is hard to pick the ideal time to visit Kakadu. In the wet season large areas of the park are closed to the public. It would not be possible to enter or exit from the park through the Kakadu Highway. Most of the people there agree that the best time to visit is at the end of the dry season. Some areas of Kakadu have restricted visiting times, and some are not open to the general public. Over 230 000 tourists visit Kakadu National Park every year. As you enter Kakadu National Park, you will be requir ed to buy a permit. Part of this money is paid to the Traditional Owners of the land and the rest is given to the repairs of the park.

66. Why does the author mention so much wildlife in Paragraph 1?

   A. To represent the scene of the nature.               B. To attract readers’ attention.

   C. To take the wildlife for example.                        D. To show the value of the park

67. Kakadu is given double World Heritage status by the United Nations because of ___.

   A. the descendants of these First Australians still in Kakadu today

   B. the particular environment and the unusual rock art

   C. the longest continuous human culture that exists in the world

   D. Aborigines living in this area for at least 40,000 years

68. The followings are mentioned in the passage except _____.

   A. living things in Kakadu                                        B. the escarpment and the gorges

   C. the history of the park                                                 D. the weather of the area

69. The underlined word gorges in Paragraph 3 means______.

   A. narrow valleys between hills or mountains           B. buildings where cases are determined

   C. large and open structures for sports events                  D. places where something is located

70. What does the author advise visitors to do when they go to Kakadu?

   A. To get more information about the special place

   B. To make a better choice between the wet or dry season

   C. Not to enter the national park without permission.

   D. Not to go there through the Kakadu Highway
