Đáp án A

Giải thích: reduce the risks, khi đó the risk là tân ngữ nên khi đảo lên làm chủ ngữ ta phải dùng nó ở dạng bị động - C và D thiếu to be bị loại. Sau can ta dùng động từ nguyên thể nên chọn A.

Dịch nghĩa. Nguy cơ phát triển ung thư có thể được giảm thiểu đáng kế bằng cách không hút thuốc và ăn uống điều độ.

A

“were increased” -> “was increased”. Chủ ngữ trong câu là “the popularity” – danh từ không đếm được, vì thế động từ to be đúng phải là was

Therapeutic cloning

Reproductive cloning involves implanting a cloned embryo into a uterus in the hope of producing a healthy foetus. A company called Clonaid claims to have successfully cloned thirteen human babies. They say that all  of the babies are healthy and are in various location including Hong Kong, UK, Spain and Brazil. Clonaid states that they are using human cloning to assist infertile couples, homosexual couples and families who have lost a beloved relative.

The same technology can be used for animal cloning. If endangered species such as the giant panda and Sumatran tiger could be cloned, they could be saved from extinction. Livestock such as cows could also be cloned to allow farmers to reproduce cattle that produce the best meat and most milk. This could greatly help developing countries where cows produce significantly less meat and milk.

According to the passage, which of the following is NOT true?

A. Cloning technology can help cure back and neck injuries.

B. The first dog to be cloned was in Korea

C. Many countries can use cloning technology to produce more meat and milk

D. Diabetes can’t be cured by using cloning technology

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

Alzheimer's disease impairs a person's ability to recall memories, both distant and as recent as a few hours before. Although there is not yet a cure for the illness, there may be hope for a cure with a protein called nerve growth factor. The protein is produced by nerve cells in the same region of the brain where Alzheimer's occurs. Based on this relationship, scientists from the University of Lund in Sweden and the University of California at San Diego designed an experiment to test whether doses of nerve growth factor could reverse the effects of memory loss caused by Alzheimer's. Using a group of rats with impaired memory, the scientists gave half of the rats doses of nerve growth factor while giving the other half a blood protein as a placebo, thus creating a control group. At the end of the four-week test, the rats given the nerve growth factor performed equally to rats with normal memory abilities. While the experiments do not show that nerve growth factor can stop the general process of deterioration caused by Alzheimer's, they do show potential as a means to slowing the process significantly.

Which of the following could best replace the word "significantly"?

A. considerably    

B. knowingly        

C. suggestively      

D. tirelessly

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.

         Mr. Faugel was convinced that students’ nervousness had affected their scores; to reduce the anxiety of these students who had already been tested, he gave 22 of them a beta blocker before readministration of the test. Their scores improved significantly. The other 8 students (who did not receive the beta blockers) improved only slightly. Second-time test-takers nationwide had average improvements which were similar to those in Faugel's non-beta blocker group.

           Beta blockers are prescription drugs which have been around for 25 years. These medications, which interfere with the effects of adrenalin, have been used for heart conditions and for minor stress such as stage fright. Now they are used for test anxiety. These drugs seem to help test-takers who have low scores because of test fright, but not those who do not know the material. Since there can be side effects from these beta blockers, physicians are not ready to prescribe them routinely for all test-takers.

A. build up           

B. lessen      

C. increase  

D. maximize
