III. Reading Comprehension. In this part, you will read several passages. Each one is followed by a number of questions. Question 26 to 40, you should choose the ONE best answer to each question. 2 points each.

Dariusz Leszczynski, a research professor at Finland's Radiation and Nuclear Safety Authority in Helsinki, has done studies indicating that radio frequency radiation may create a stress reaction in the cells that line blood vessels, leading to a dangerous breach in the blood-brain barrier. "Mobile-phone radiation may be able to indirectly hurt cells, perhaps by interfering with their ability to repair normal DNA damage," he says. "Given the scientific uncertainty, it's premature to say the use of cell phones is safe."

If radio frequency radiation increases the chances of developing brain cancer, it should show up in long-term studies of cell-phone users. But many epidemiological studies have found no clear connection, including a 2007 Danish Cancer Society study of 421,000 cell-phone users, which led many in the media to conclude that mobiles are harmless. To date, "peer-reviewed scientific evidence has overwhelmingly indicated that wireless

(A) the autobiography of Dariusz Leszczynski. (B) problems with many of these studies. (C) the development of brain cancer. (D) peer review of cell phones.

While fats have lately acquired a bad image, one should not forget how essential they are. Fats provide the body’s best means of storing energy, a far more efficient energy sources than either carbohydrates or proteins. They act as insulation against cold, as cushioning for the internal organs, and as lubricants. Without fats, energy would have no way to utilize fat-soluble vitamins. Furthermore, some fats contain fatty acids that contain necessary growth factors and help with the digestion of other food.

An important consideration of fat intake is the ratio of saturated fats to unsaturated fats. Saturated fats, which are derived from dairy products, animal fats, and tropical oils, increase amount of cholesterol in the blood. Cholesterol may lead to coronary heart disease by building up in the arteries of the heart. However, unsaturated fats, derived from vegetable oils, tend to lower serum cholesterol if taken in a proportion twice that of saturated fats.

The consumption of a variety of fats is necessary, but the intake of too much fat may lead to a variety of health problems. Excessive intake of fats, like all nutritional excesses, is to be avoided.

28. Comparing with carbohydrates or proteins, fats

(A) store food more efficiently. (B) deserve their bad image. (C) consume more oils. (D) provide more fluids.

Which of the followings is the main idea of 29. The main idea of the third paragraph is that

(A) people are eating less and less fat today. (B) fats should be eliminated. (C) excessive consumption of fats may be dangerous to one’s health.

(D) fats taken in the proper proportion may reduce serum cholesterol. 30. With which of the following is the whole passage primarily concerned? (A) The role of fats in human health (B) The dangers of cholesterol (C) The benefits of fats in the diet (D) The importance of good nutrition

Gender Equity

(1) In the past decade, increasing attention has been paid to the issue of gender equity in the science, technology, engineering, and mathematics (STEM) fields. Research publications, including the American Association of University Women Educational Foundation's Tech Savvy (2000) and Women at Work (2003), have documented the troubling shortage of girls and women preparing to work in these fields. In response to this "shrinking pipeline" of girls and women in STEM, a wide array of programs and strategies has been promoted and funded by governmental and nongovernmental organizations.

(2) The AAUW Educational Foundation and the National Science Foundation are among the top

invested nearly $90 million to fund more than 400 projects specifically aimed at increasing the participation of girls and women in STEM fields. This body of projects presented a unique opportunity to explore the nature of gender equity intervention projects in STEM. Until now, no comparable survey of gender equity intervention projects in STEM has been done.

(3) The research for this report, led by Yasmin Kafai and a team of researchers at the University of California, Los Angeles, was guided by several overarching questions: What types of projects have been funded within and across the various STEM disciplines? Are there areas where we have concentrated our efforts, and areas we have overlooked? What patterns emerge among the project types and disciplines? (4) The findings document impressive efforts in preparing girls and women for science, technology, engineering, and mathematics studies and careers and demonstrate a rich and diverse body of gender equity intervention projects within all STEM disciplines. About two-thirds of the projects involved extracurricular informal learning activities such as museum visits and field trips. Equally important were mentoring activities in many forms, ranging from traditional one-to-one to large-scale online versions, and professional

development activities, such as course taking and network building, that were successfully integrated into projects.

(5) At the same time, the findings reveal some troubling trends. Many projects focused predominantly on career advice without providing access to necessary skill and content development. A majority of projects occurred outside the school curriculum. While such extracurricular1 projects can be effective and valuable, the overall lack of integration into the school curriculum suggests that gender equity remains on the margins of teaching and learning in the STEM fields. Finally, an absence of data on participant demographics and a lack of project evaluation make it difficult to determine who is being served and if and how project outcomes are being measured.

31. What does the phrase "shrinking pipeline" in paragraph refer to?

(A) the shortage of oil supply (B) the shortage of labor supply (C) the shortage of training programs (D) an issue that is getting smaller

32. Which of the sentences below best express the essential information in the highlighted sentence in the passage 2? (Incorrect choices change the meaning in important ways or leave out essential information.) (A) These projects allowed us to study the differences between men and women employed in STEM jobs. (B) We were able to intervene when women STEM workers were being treated unfairly.

(C) Studying these projects helped to create more gender equity intervention projects. (D) STEM jobs were able to be studied by exploring nature.

33. In paragraph 3, "Are there areas where we have concentrated our efforts, and areas we have overlooked?" In this sentence, "we" refers to

(A) the author and his/her coworkers. (B) people involved in creating gender equity projects. (C) people in the STEM disciplines. (D) Yasmin Kafai and his team.

34. According to paragraph 4, what is one positive finding of this research?

(A) the STEM field is rich and diverse (B) many projects involved mentoring opportunities (C) girls and women are being prepared for STEM jobs (D) the quality of the questions asked 35. According to paragraph 5, what is one negative trend discovered through this research? (A) access to unnecessary content (B) extracurricular projects were common (C) evaluation of the projects was too specific (D) focus on career advice

Chili peppers are decidedly an international phenomenon, spicing up regional dishes from Thailand to North Africa. In Thailand Confidential, this week’s Globalist Bookshelf selection, Jerry Hopkins gives insight

to the culture and history surrounding this fiery fruit (yes, technically a fruit) and highlights how it may be one of the world’s best medical miracles.

In Thailand-where restaurants rate their dishes by placing one, two, three, and sometimes four little red chilis on the menu next to the dishes’ names to alert diners-I am tolerated. Barely.

A longtime friend, who is a Thai chef, used to bring home food purchased at street stalls and as she placed this on the table, she would point to one container and say, “Mine,” then to another, saying, “Yours.” As if to say, “Poor dear.”

Thailand is not the birthplace of the Capsicum, or chili pepper; it only acts as if it is. In fact, the chili was imported, along with much else in the national diet. However, in Thailand the per capital consumption of the small, fiery fruit is surely as high if not higher than it is anywhere else. And it is in the use of unprocessed, fresh, ripe chilis where Thailand rings all the loudest bells.

The truth is that chili is an international phenomenon. There is a bimonthly magazine published in the United States, Chili Pepper (there is no agreement on the spelling), and a wide variety of products is available, including pepper-shaped wind chimes, bells, and strings of Christmas tree lights. There is even a Hot Sauce Club of America; members receive two new hot sauces and a newsletter every month. There is even a popular American rock and roll band that calls itself the Red Hot Chili Peppers. Yes, the band is hot.

36. From these passages, we learn that the author (A) enjoys chili peppers everywhere. (B) does not really like chili peppers.

(C) likes to have chili peppers to go with some certain kind of food. (D) like to go to restaurant famous for chili peppers.

37. The best title for these passages is

(A) Thailand and Chili peppers. (B) Chili Peppers and Spicy Dishes. (C) Different Tastes all over the World. (D) Chili Peppers and Globalization. 38. Based on the passages, which of the following is NOT TRUE?

(A) That Thailand uses unprocessed, fresh, ripe chili peppers has started the popularity of chili peppers. (B) Thailand exports a lot of chili peppers.

(C) Chili peppers are a kind of fruit. (D) Thai food is normally quite spicy. 39. What does per capital consumption mean?

(A) amount consumed per person within a specific population. (B) capital population and its consumption.

(C) capital with that the government provides each person for food consumption. (D) capital that each person can get for their daily food consumption.

40. What is the main idea of the last paragraph?

(A) Chili peppers are very popular in the United States.

(B) The use of chili peppers in the United States is being influenced by Thailand. (C) Chili peppers are made into different toys.

(D) Chilli peppers have made a rock band very hot.

IV. Essay. 20 points.

Please write a well-structured essay on how you can prepare yourself for living in a diverse and more global society in 150 to 200 words discussing your opinions.
