分析 阿司匹林不僅僅被證明對減少疼痛和治療發(fā)燒很重要,而且還有另外一些阿司匹林能起作用的方面.

解答 答案:C 當(dāng)否定詞或者半否定詞放在句首的時候,后面的主句要使用部分倒裝的形式.本句中的not only放在了句首,后面使用部分倒裝的形式.根據(jù)句意可知,阿司匹林不僅僅被證明對減少疼痛和治療發(fā)燒是已經(jīng)被證明的,所以使用使用完成時.所以選擇C.

點評 部分倒裝即只把謂語的一部分(如助動詞、情態(tài)動詞等)放到主語前,或把句子的強調(diào)成分提前.

19.Sea turtles come in many different sizes,shapes and colors.The shell of each sea turtle species is different in length,color,shape and the arrangement of the scales(鱗片).
Sea turtles do not have teeth but use their jaws (下巴)to eat.Their sense of smell is excellent.Th eir eyesight underwater is good,but they have near-sighted eyes out of water.Their special bodies make them adapt to life at sea.However,sea turtles maintain(保持) close ties to land.
Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore,all baby sea turtles begin their lives on land.Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest,largely because they ca n be found most easily.After decades of studying sea turtles,much has been learned about.However,many mysteries(謎) still remain.
Researchers do not yet know how long baby turtles spend in the open sea,or exactly where they go.People believe they spend their earliest years floating in the sea,where they do little more than eat and grow.Once turtles reach dinner-plate size,they appear at feeding grounds in waters near the shore.They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles,depending on the species.There is no way to know the age of a sea turtle from its physical appearance.It is believed that some species can live for over 100 years.

14.Sydney-A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23.It was the third shark attack along the coast of Australia's largest city in a month.
The 15-year-old boy and his father were in the water off Avalon,on Sydney's northern beaches,around dawn when he was attacked.The city's beaches are packed with locals and tourists during the summer months.
"The father heard a scream and turned to see his son trashing (扭動) about in the water,"police said."Fortunately,the shark swam away and the boy was helped to shore by his father."
Lifesaving Club spokesman Nick Miller said,"It got him around the top of his left leg and the father came and dragged his out of water."He said the boy was bleeding heavily when he was brought to the shore."There was a lot of pain,as you can imagine."The teenager was airlifted to hospital for treatment for leg injuries.
Police said the bites"cut through to the bone",but the boy did not appear to have sustained any fractures (骨折).He was in a stable condition now.
Several beaches were closed after the attack.Water police and lifeguards were searching for the shark,while police hoped to identify its species by the shape of the bite marks.But they said it was too early to say what type of shark attacked the boy."I don't even know if he saw it,"Miller said.
Many shark species live in the waters off Sydney's beaches,but attacks on humans are still relatively rare.However,there were two attacks on successive days earlier this month,one on a navy diver in Sydney harbor,not far from the famous Opera House,and the other on a surfer at the city's world-famous Bondi beach.
Fishermen say shark numbers are on the rise.There is a ban on commercial fishing in the harbor,which has increased fish stocks.Marine experts also claim environmental protection has created a cleaner environment,attracting sharks closer to the shore as they chase fish.Many shark species,including the Great White-the man-eaters made famous in Steven Spielberg's Jaws-are protected in Australian waters.

63.What do we know about the city of Sydney from the passage?B
A.It is one of the largest cities in Australia.
B.Sydney harbor is not far from the famous Opera House.
C.There are many locals and tourists on its coast all the year round.
D.There are few shark species in the waters off Sydney's beaches.
64.The underlined word"savaged"in the first paragraph probably means"C".
A.a(chǎn)ttracted   B.dragged   C.bit   D.packed
65.About the injury of the boy we know thatA.
A.he was losing much blood when he was dragged out
B.he was very nervous when he was sent to hospital
C.he may be in danger of losing his leg    
D.he was injured in the right leg
66.All the following are the causes of Australia's sharks increasing EXCEPT thatD.
A.environmental protection has created a cleaner environment
B.a(chǎn) ban on commercial fishing has increased fish numbers
C.many shark species are protected in Australian waters
D.the film Jaws has made the Great White famous.

18.It was Sunday yesterday and my son and I walked a couple of miles in the morning.We got hungry so we decided to stop for a meal in a restaurant.While we were waiting in a line,a woman came in.She was very angry and talking about a beggar who had asked her for money.In her opinion,those people had the ability to earn their bread and butter.
I was feeling uncomfortable with the situation and wondering what I should say to my son later.I had told him that we should help those who were in need of help.At that time the lady said,"Today is my birthday,and nobody can bother me."
I knew this was my chance to help her change her thinking and to help her feel cared for on her birthday.I asked the waitress for help,telling her I wanted to pay for the woman's meal.
The waitress looked at me in surprise.I paid for our meal and that of the woman.When the woman finished eating her food,the waitress told her that it was I who had paid for her meal.Then the woman came to our table and tried to force her money on us.She even said,"I can't take your money,because I didn't help the person who asked me for money for food!"
I just smiled and said,"I just hope you have a very nice birthday."
She ended up sitting near us and talked with us.It turned out that she was crazy about animals.Hearing our stories of pet adoptions really cheered her up."You are a nice father,"she said.
