A team of Russian scientists has challenged the theory that the woolly mammoths became extinct 10,000 years ago at the end of the Ice Age. The scientists have reported that the beasts may have survived until 2000 B.C. on an island off the coast of Siberia, where researchers uncovered 29 fossilized woolly mammoth teeth ranging in age from 4,000 to 7,000 years. The question to be asked now is, how did these prehistoric pachyderms survive in their island environment? One possibility is that they adapted to their confined surroundings by decreasing their bulk. This theory is based on their smaller tooth size, which has led scientists to believe that they were only 6 feet tall at the shoulder compared with 10 feet of their full-sized counterpart. But would this be enough to enable them to survive thousands of years beyond that of other mammoths? Researchers are still working to uncover the reasons for this isolated group's belated disappearance.
According to the scientists, the woolly mammoths may have managed to survive because they
A. shed their hair
B. grew smaller teeth
C. became herbivores
D. decreased in size
Trả lời:
Chọn đáp án D
Dựa theo các nhà khoa học, voi ma mút lông xoăn có lẽ đã sống sót bởi vì ______
A. rụng bớt lông
B. mọc răng nhỏ hơn
C. trở thành loài ăn cỏ
D. giảm về kích cỡ
Giải thích: “This theory is based on their smaller tooth size, which has led scientists to believe that they were only 6 feet tall at the shoulder compared with 10 feet of their full-sized counterpart.” (Lý thuyết này dựa vào cỡ răng nhỏ của voi ma mút, cái mà đã làm cho các nhà khoa học tin rằng chúng chỉ cao 6 feet tại vai so với 10 feet của voi tổ tiên.) => giảm từ 10feet xuống còn 6feet.
Dịch bài đọc:
Nhóm các nhà khoa học Nga đã “thách thức” lý thuyết về voi ma - mút lông xoăn bị tuyệt chủng cách đây 10,000 năm vào cuối kỷ băng hà. Họ cho rằng những con quái vật này có thể vẫn còn tồn tại cho đến năm 2000 Trước công nguyên trên đảo ngoài khơi Siberia, nơi nhà nghiên cứu khám phá 29 hoá thạch răng voi ma - mút lông xoăn từ 4,000 đến 7,000 năm tuổi. Câu hỏi để được đặt ra bây giờ là, làm cách nào mà loài da dày từ thời tiền sử này tồn tại ở môi trường đảo?
Lý thuyết này dựa vào cỡ răng nhỏ của voi ma mút, cái mà đã làm cho các nhà khoa học tin rằng chúng chỉ cao 6 feet tại vai so với 10 feet của voi tổ tiên. Nhưng sẽ này có đủ để chúng có thể tồn tại hàng ngàn năm ngoài của voi ma - mút khác? Nhà nghiên cứu vẫn còn đang làm việc để khám phá lý do biến mất trễ muộn này.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the
correct word or phrase that best fits each of the numbered blanks. Fill in the appropriate word in question 33
Wind, water, air, ice and heat all work to cause erosion. As the wind blows over the land, it often (33)_______ small grains of sand. When these grains of sand strike against solid rocks, the rocks are slowly worn away. In this way, (34)_______ very hard rocks are worn away by the wind.
When particles of rocks or soil became loosened in any way, running water carries them down the hillsides. Some rocks and soil particles are carried into streams and then into the sea.
Land that is covered with trees, grass and other plants wear away very slowly, and so loses very (35)_______ of its soil. The roots of plants help to hold the rocks and soil in place. Water that falls on grasslands runs away more slowly than water that falls on bare ground. Thus, forests and grasslands help to slow down erosion.
Even where the land is (36)_______ covered with plants, some erosion goes on. In the spring, the melting snow turns into a large quantity of water that then runs downhill in streams. As a stream carries away some of the soil, the stream bed gets deeper and deeper. (37)_______ thousands of years of such erosion, wide valleys are often formed.

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 from 1 to 8.
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.
According to the passage, which of the following is NOT a possible cause of many heart attacks?
