Đáp án C

Khi mệnh đề quan hệ ở dạng bị động, ta có thể dùng quá khứ phân từ của động từ tròn mệnh đề để rút gọn câu.

Đáp án A sai vì trong câu chỉ có một mệnh đề chính duy nhất nên không dùng Although ¬ liên từ chỉ sự đối lập giữ các mệnh đề được.

Đáp án B sai vì ta đã có mệnh đề rút gọn called protoplasm nên nếu rút gọn consisting of câu sẽ không có động từ chính làm vị ngữ.

Đáp án D sai vì nếu có In đằng trước thì cả câu sẽ đóng vai trò là một mệnh đề trạng từ và câu sẽ không có chủ ngữ và vị ngữ.

Dịch nghĩa: Tất cả các sinh vật sống bao gồm một hoặc nhiều đơn vị vật chất gọi là chất nguyên sinh

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 55 to 64.

The livelihood of each species in the vast and intricate assemblage of living things depends on the existences of other organisms. This interdependence is sometimes subtle, sometimes obvious. Perhaps the most straight forward dependence of one species on another occurs with parasites, organisms that live on or in other living things and derive nutrients directly from them. The parasitic way of life is widespread. A multitude of microorganisms (including viruses and bacteria) and an army of invertebrates - or creatures lacking a spinal column (including crustaceans, insects, and many different types of worms) - make their livings directly at the expense of other creatures. In the face of this onslaught, living things have evolved a variety of defense mechanisms for protecting their bodies from invasion by other organisms.

Certain fungi and even some kinds of bacteria secrete substances known as antibiotics into their external environment. These substances are capable of killing or inhibiting the growth of various kinds of bacteria that also occupy the area, thereby eliminating or reducing the competition for nutrients. The same principle is used in defense against invaders in other groups of organisms. For example, when attacked by disease - causing fungi or bacteria, many kinds of plants produce chemicals that help to ward off the invaders. Members of the animal kingdom have developed a variety of defense mechanisms for dealing with parasites.

Although these mechanisms vary considerably, all major groups of animals are capable of detecting and reacting to the presence of "foreign" cells. In fact, throughout the animal kingdom, from sponges to certain types of worms, shellfish, and all vertebrates (creatures possessing a spinal column), there is evidence that transplants of cells or fragments of tissues into an animal are accepted only if they come from genetically compatible or closely related individuals. The ability to distinguish between "self" and "nonself", while present in all animals, is most efficient among vertebrates, which have developed an immune system as their defense mechanism. The immune system recognizes and takes action against foreign invaders and transplanted tissues that are treated as foreign cells.

All of the following are defined in the passage EXCEPT ________.

A. parasites (paragraph 1) 

B. invertebrates (paragraph 1)

C. nutrients (paragraph 2)

D. vertebrates (paragraph 3)

Dịch bài đọc:

Nước có tầm quan trọng sống còn đối với mọi sinh vật. Không có nó, tất cả các sinh vật sống chắc chắn sẽ chết. Chúng ta cũng sử dụng một lượng nước lớn hàng ngày trong nhà, trong các nhà máy và trong các nhà máy điện. Hầu hết nước này là nước ngọt và nó đến với chúng ta từ các hồ chứa, sông hồ.

Bề mặt Trái đất được bao phủ bởi những vùng nước rộng lớn mà chúng ta gọi là đại dương và biển. Nếu bạn đã nếm nước từ biển, bạn sẽ biết rằng, không giống như nước ngọt, nước biển có vị mặn. Điều này là do sự hiện diện của natri clorua đến từ đất. Sông mang nó ra biển.

Mặc dù cả nước mặn và nước ngọt đều không có màu gì, biển thường có màu xanh dưới ánh sáng mặt trời. Lý do là ánh sáng mặt trời được tạo thành từ nhiều màu sắc. Một số màu biến mất nhanh chóng trên biển nhưng ánh sáng xanh bị dội ngược lại hoặc bị phản xạ, lên bề mặt. Điều này làm cho biển trông xanh.
