閱讀下面短文，簡要回答問題。
The World Health Organization estimates (估計) 20,000,000 babies are born too small each year. It says a baby weighing less than 2,500 grams at birth has a less than desirable weight for good health. 95 percent of such children are born in developing countries.
One recent study shows that pregnant (懷孕的) women in developing countries have healthier babies if the women are given vitamins. Researchers from the United States and Tanzania found that vitamins could help reduce low birth weight. Their findings were reported last month in The New England Journal of Medicine.
Wafaie Fawzi of the Harvard School of Public Health led the study. Professor Fawzi says low birth weight can cause serious health problems in babies. He says low birth weight has been linked to poor growth and mental development, and even early death.
There are fourteen kinds of vitamins. People who do not get enough of these chemicals in their food, or want more, often take multivitamins (多種維生素).In the study, multivitamin pills were given to 4,200 pregnant Tanzanian women.The pills contained all the Bvitamins,as well as vitamins C and E. They also embodied iron and other nutrients in levels several times higher than advised for women in industrial nations.
Four thousand other women received a harmless substance(物質(zhì)). None of the women had the virus that causes the disease AIDS.
68．On what condition can pregnant women in developing countries have healthier babies?

第三部分：閱讀理解（共15小題，每題2分，滿分30分）
閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。
Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in a bid
to cut the emission of greenhouse gases blamed for global warming.
Thanks to special bacteria in their stomachs, kangaroo farts contain no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas.
While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide, livestock passing wind contribute a surprisingly high percentage of total emissions in some countries.
"Fourteen percent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland state government.
"And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said.
Researchers say the bacteria also makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.
But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.
Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.
The idea is controversial（爭議）, but about 20 percent of health conscious Australians are believed to eat the national symbol already.
"It's low in fat, it's got high protein levels and it's very clean in the sense that basically it's the ultimate free range animal（散養(yǎng)動物）," said Peter Ampt of the University of New South Wales's institute of environmental studies.
56. According to the passage, global warming is now mainly caused by _____ .
A. methane  B. carbon dioxide  C. livestock passing wind  D. not mention in this passage
57. What does the underlined phrase “the idea”（paragraph 9）refer to?
A. Australians should give kangaroo-style stomachs to cattle and sheep.
B. The bacteria could make the digestive process much more efficient.
C. Australians should farm fewer cattle and sheep and just eat more kangaroos.
D. The bacteria could potentially save millions of dollars in feed costs for farmers.
58.  How will Australian scientists solve the problem of global warming?
A. Eating more kangaroos.  
B. Killing more cattle and sheep.
C. Letting cattle and sheep pass less wind.
D. Transferring the special bacteria in kangaroos’ stomachs to cattle and sheep.

Dear Abby,
This is my first letter to you, although I have been reading your column for many years. I need an outside opinion.
I am a grandmother in my 70s and have just returned from visiting my daughter, her husband and their three dearly loved children--all under the age of 5--and I'm upset with some of their parenting ways.
For example: They lock the doors to their children's bedrooms at night because the children might get out of their beds and wander around the house, and we may not hear them."
If one child should get punishment, all three are punished, and if one child says a naughty
word, all three are given hot sauce (辣醬汁) in the mouth. I know these parents love their children very much, but are these ways of disciplining them wise? Please understand, it is not my aim to interfere (干涉).
--- Gram
Dear Gram,
Children's bedroom doors should not be locked. Should a flash fire break out, it would be a nightmare (噩夢).Punishing all the children when only one has earned the punishment is a good way to make them grow up to hate each other. Children who use "naughty" words should not be punished with hot sauce in the mouth-they should be taught the proper and acceptable word to use instead of the "naughty" word. 
---  Abby
49. Gram's daughter _____________.
A. is very strict with her children            B. does not love her three children
C. always punishes her children at night      D. often gives her children hot sauce
50. The passage doesn't say so, but from the lines you'll find that __________.
A. Gram likes writing letters               B. Gram likes watching children
C. Gram likes reading newspapers          D. Gram likes visiting her daughter
51. Gram writes the letter in order to ____________.
A. disclose her daughter's ways as a mother        
B. criticize her daughter's ways as a mother
C. express her anger about her daughter s ways as a mom
D. get others' opinion about her daughter's ways as a mom
52. Which of the following is NOT true according to the passage?
A. Gram seems to care for her grand children very much.
B. Gram is against some of her daughter's ways as a mom.
C. Abby is for only one of Gram's daughter's ways as a mom.
D. Abby agrees with Gram about her daughter's ways as a mom.

　　The third theme of geography is movement. As people travel around the world, exchanging goods, ideas and interests, the global community is transformed. Take surfing, for example, the sport originated in Hawaii centuries ago. Today, the cry “surf up!” can be heard along coastlines everywhere.
　　Europeans were the first Westerners to observe the sport. In 1779, Captain Cook, a British explorer, and his crew sailed around the Sandwich Islands ( Now Hawaii ). Near the rocky coast of the Big Island, they witnessed a man riding a wave while standing on a board.
　　Cook was stricken by what he saw. Hawaiians would pray for good waves and hold ceremonies when building surfboards. Their boards were built according to rank: Chiefs used long boards (16 to 18 feet long ), while commoners used shorter ones (6 to 8 feet long ).
　　After the arrival of Europeans, Hawaiian surf culture declined. Many Hawaiians died of European-borne diseases. Also, Christian missionaries (傳教士) spread the belief that surfing was “ignorant (愚昧的)fun”.
These conditions changed after Hawaii became a United States territory in 1900( It became a state in 1959.) Travelers to the islands brought back stories of wave riding. Tales of the thrilling sport spread across the U.S., then to the rest of the world.
　　Today, surfing is the king of board sports. According to wannasurf.com, the world has nearly 8,000 “surf spots” in 136 countries on 6 continents. The Association of Surfing professionals (ASP) holds an annual world tour in which top riders compete for millions of fans on the waves.

We typically associate the word “science” with a person in a white coat doing experiments in a laboratory. Ideally, experiments should play as big a role in the human sciences as they do in the natural sciences; but in practice this is not usually the case. The are at least three reasons for this.
1．Human scientists are often trying to make sense of complex real world situations in which it is simply impossible to run controlled experiment.
2．The artificiality of some of the experiments that can be conducted may make the behavior of the participants abnormal.
3．There are moral reasons for not conducting experiments that have a negative effect on the people who participate in them.
Faced with the above difficulties, what are human scientists to do? One solution is to wait for nature to provide the appropriate experimental conditions. We can, for example, learn something about how a normal brain functions by looking at people who have suffered brain damage; and we can gain some understanding into the roles played by genes and the environment by studying twins, who have been separated at birth and brought up in different families. In the case of economics, economic history can provide us with a bank of-admittedly not very well-controlled-experimental data.
However, human scientists do not just sit around waiting for natural experiments to arise. They also think of some experiments of their own. Suppose you want to know how a baby sees the world. We cannot, of course, ask the baby since it has not yet learnt to speak. So it might seem that all we can do is guess. People usually won’t change their mind until it was found out that babies tend to stare at surprising things longer than at unsurprising ones. This key understanding was like opening a window on to the developing mind. There was now a way of testing babies’ expectations and getting some idea of how they are six months old, babies can already do the following things: figuring out that objects consist of parts that move together being aware of the difference between living and non-living things and even doing simple arithmetic work.
60．What is true about the natural sciences and the human sciences according to this passage?
A．Both human scientists and natural scientists can run controlled experiments.
B．Experiments done by human scientists and natural scientists are artificial.
C．Both human and natural science experiments should be of the same importance.
D．It’s not moral to conduct human science experiments.
61．What do we know about human scientists from this passage?
A．They are white coat scientists.
B．They have more experimental sources than natural scientists.
C．They conduct experiments passively.
D．They face more difficulties in carrying out their research.
62．Which of the following experiments belongs to human science experiment?
A．Vinegar Volcano Vinegar and baking soda make. for a fun and easy science experiment. Try creating a vinegar volcano.
B．Taste Without Smell Put your senses to the test with this simple experiment that shows the
importance of your sense of smell.
C．Lung Function Observe your breath and confirm your lung volume by completing this experiment.
D．Make a Rainbow Use sunlight and water to make your own rainbow with this cool experiment
that will teach kids how rainbows work while they enjoy a fun activity
63．What does the author tell us in this passage?
A．ABCs about the science experiment.
B．Some knowledge of science.
C．Some differences between the human sciences and the natural sciences.
D．The similarity of the natural sciences and the human sciences.

Teenagers at one German school are learning how to achieve happiness alongside other traditional subjects such as math and languages.
The class sit in a circle with their eyes shut and they count from one to ten: someone starts, the next voice comes from the far right, a third from the other side.
The aim of the game is to listen for an opportunity to shout out the number without clashing (沖突) with another voice or leaving a pause. On the first try, most of the young Germans try to be first, while a few are too shy to join in, but by the fifth time round, they develop a rhythm. The message: give other people space but also confidently claim your own. This is a requirement for social well-being.
The Willy Hellpach School in Heidelberg is the first in the nation to develop a happiness course. It is intended for students preparing for university entrance exams.
“The course isn’t there to make you happy,” Ernst Fritz-Schubert, the school principal, warned pupils, “but rather to help you discover the ways to become happy.”
Cooking a meal together is one of the class exercises. Improving body language under the guidance of two professional actresses is another.
The course is taught for three periods a week. Despite the happy subject, the pupils themselves insist it is no laughing matter.
“In the first period, we had to each say something positive about another member of the class and about ourselves. No laughing at people,” said Fanny, 17.
Research by the school shows it is not the first to start happiness classes: they also exist at some US universities, mainly based on positive thinking, using findings from studies of depression.
68. This passage is written to           .
A. introduce the happiness course in a German school
B. describe all the traditional courses in a German school
C. arouse the readers’ interest in happiness
D. help students struggle against being sad
69. According to the passage, the happiness course is__________.
A. created by the Willy Hellpach School
B. to make all the students happy all the time
C. required to be taken by the first year students
D. to help students discover the way to happiness
70. It can be inferred from the passage that__________.
A. the students’ self-respect can also improve happiness
B. the students just took the course as a laughing matter
C. the students can certainly become happy after the course
D. the students waste time learning something without value

Sandeep Mukerji was on his first visit to Thailand but would leave the “Land of Smiles” with a frown and an empty pocket.
A stone’s throw from the Grand Palace in Bangkok, the 26-year-old Canadian ran into a monk in a robe. The monk told him that the attraction he was hoping to visit had been closed.
The monk then introduced Mukerji to a jewellery store instead. On the way there, three different people told him that it was the last day of a once-a-year, tax-free jewellery promotion to encourage tourism.
They said that tourists can make a lot of money by buying gems（寶石）in Thailand and selling them once at home.
Two hours later, Mukerji had spent US $ 1, 250 on a set of almost worthless jewellery in the jewellery store.
“The whole process took me by surprise. They take advantage of your greed,” he said.
In fact, Mukerji is just one of a huge number of tourists who are cheated by the promise of making a fortune. The scam（詭計）brings Thailand more than US $ 10 million each year.
Although tourist police stations have displayed posters to warn of the scam, many fresh-faced tourists still fall prey to the trick.
The police say they receive 5～10 complaints a day. Many more may not realize they have been cheated until they go back home.
That authorities say that the jewellery scam is harmful to Thailand’s image, but getting rid of the cheats is hard.
Sanit Miphan, head of the police, said the scam has been running for about 15 years but not one jewellery shop owner has been arrested.
The shops usually open for two weeks and then close. They reopen and register under a new name. What’s more, overcharging（要價過高）itself is not breaking the law.
Yet, to keep the tourism business alive, the police said they would take action against any shop receiving more than 10 complaints.
73. Sandeep Mukerji was cheated probably because of all the following EXCEPT that_______.
A. he was young
B. he believed that the monk wouldn’t cheat others
C. he had more or less the wish to try his fortune
D. the cheat scam was too skillful to be found out
74. How many people cheated Sandeen Mukerji?
A. Two        B. Three       C. Four          D. Five
75. Suppose everyone who was cheated lost as much as Mukerji did, how many visitors to Bankok would be cheated each year?
A. About 6, 000   B. About 8, 000   C. About 10, 000.    D. About12, 000.
76. Which of the following statements is TRUE?
A. Thai tourist police are carrying out their task very efficiently.
B. The management of Thai tourist market is very strict.
C. Any shop receiving complaints will be punished as seriously as possible.
D. It is hard for the police to crack down（制裁） the cheats efficiently partly because many cheats’ deeds seem not to break the law.
