Bởi bệnh tim tiếp tục là căn bệnh chết người số một tại Hoa Kỳ, các nhà nghiên cứu ngày càng quan tâm đến việc xác định các yếu tố nguy cơ tiềm ẩn gây ra các cơn đau tim. Chế độ ăn có hàm lượng chất béo cao và "cuộc sống trên làn đường nhanh" từ lâu đã được biết đến góp phần gây ra bệnh tim. Tuy nhiên, theo các nghiên cứu mới, danh sách các yếu tố nguy cơ có thể dài hơn đáng kể và khá đáng ngạc nhiên.
Ví dụ như chứng suy tim, dường như theo thời vụ và thời gian. Tỷ lệ cơn đau tim xảy ra cao hơn trong thời tiết lạnh, và nhiều người bị suy tim vào thứ Hai hơn bất kỳ ngày nào trong tuần. Ngoài ra, người ta dễ bị đau tim hơn trong vài giờ đầu sau khi thức dậy. Các nhà tim mạch lần đầu tiên quan sát thấy hiện tượng này vào giữa năm 1980, và từ đó đã phát hiện ra một số nguyên nhân có thể. Vào buổi sáng sớm sự tăng huyết áp, nhịp tim, và sự tập trung các hoocmon kích thích tim, cộng với việc giảm lượng máu đến tim, có thể góp phần gây ra các cơn đau tim cao hơn vào khoảng giữa 8 giờ sáng và 10 giờ trưa.
Trong các nghiên cứu khác, cả ngày sinh nhật và đời sống độc thân đều liên quan đến các yếu tố nguy cơ. Thống kê cho thấy tỷ lệ đau tim tăng đáng kể cho cả phụ nữ và nam giới trong vài ngày ngay trước và sau sinh nhật của họ. Và những người đàn ông chưa lập gia đình có nhiều nguy cơ bị đau tim hơn những người đã lập gia đình. Mặc dù căng thẳng được cho là liên quan đến tất cả các yếu tố nguy cơ nói trên theo một cách nào đó, nghiên cứu vẫn tiếp tục với hy vọng hiểu rõ hơn tại sao và làm thế nào suy tim diễn ra.

Why is the Great Pyramid of Giza considered one of the seven wonders of the world?

As heart disease continues to be the number-one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and "life in the fast lane" have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising.
Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M.
In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is
triggered.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
One of the seven wonders of the ancient world, the Great Pyramid of Giza was a monument of wisdom and prophecy built as a tomb for Pharaoh Cheops in 2720 B.C. Despite its antiquity, certain aspects of its construction makes it one of the truly wonders of the world. The thirteen- acre structure near the Nile river is a solid mass of stone blocks covered with limestone. Inside are the number of hidden passageways and the burial chamber of the Pharaoh. It is the largest single structure in the world. The four sides of the pyramid are aligned almost exactly on true north, south, east and west-an incredible engineering feat. The ancient Egyptians were sun worshippers and great astronomers, so computations for the Great Pyramid were based on astronomical observations.
Explorations and detailed examinations of the base of the structure reveal many intersecting lines. Further scientific study indicates that these represent a type of timeline of events – past, present and future. Many of the events have been interpreted and found to coincide with known facts of the past. Others are prophesied for future generations and are currently under investigation. Many believe that pyramids have supernatural powers and this one is no exception. Some researchers even associate it with extraterrestrial beings of ancient past.
Was this superstructure made by ordinary beings, or one built by a race far superior to any known
today?

Most of the early houses built in America were suited to farm life, as it was not until cities became manufacturing centers that colonists could survive without farming as their major occupation. Among the earliest farmhouses in America were those built in Plymouth Colony. Generally they consisted of one large rectangular room on the ground floor, called a hall or great room and having a fireplace built into one of the walls, and a loft overhead. Sometimes a lean-to was attached alongside the house to store objects such as spinning wheels, firewood, barrels, and tubs. The furnishings in the great room were sparse and crudely built. Tabletops and chest boards were split or roughly sawed and often smoothed only on one side. Benches took the place of chairs, and the table usually had a trestle base so it could be dismantled when extra space was required. One or two beds and a six-board chest were located in one corner of the room. The fireplace was used for heat and light, and a bench often placed nearby for children and elders, in the area called the inglenook.
The original houses in Plymouth Colony were erected within a tall fence for fortification. However, by 1630 Plymouth Colony had 250 inhabitants, most living outside the enclosure. By 1640, settlements had been built some distance from the original site. Villages began to emerge throughout Massachusetts and farmhouses were less crudely built. Windows brought light into homes and the furnishings and décor were more sophisticated.
As more diversified groups of immigrants settled the country, a greater variety of farmhouses appeared, from Swedish long-style houses in the Delaware Valley to saltbox houses in Connecticut, Dutch-Flemish stone farmhouses in New York, and clapboard farmhouses in Pennsylvania. From Georgian characteristics to Greek revival elements, farmhouses of varied architectural styles and building functions populated the landscape of the new frontier.
