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 following questions.

Fish that live on the sea bottom benefit by being flat and hugging the contours. There are two very differcent types of flatfish and they have evolved in very separate ways. The skates ad rays, relatives of the rharks, have become flat in what might be called the obivious way. Their bodies have grown out sideways to form grat “wings”. They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely, fish such sas plaice, sole, and halibut have become flat in a different way. There are bony fish which have a marked tendency to be flattened in a vertical direction; they are much “taller” than they are wide. They use their whole, vertically flattened bodies as swimming surfaces, which undulat through the water as they move. Therefore, when their ancestors migrate to the seabed, they lay on one side than on their bellies. However, this raises the problem that one eye was always looking down into the sand and was effectively useless – In evolution this problem was soleved by the lower eye “moving” around the other side. We see this process off moving around enacted in the development of every young bony flatfish. It starts life swimming near the surface, and is symmetrical and vertically flattened, but then the skull starts to grow in a strange asymmetrical twisted fashion,, so that one eye, for instance the left, moves over the top of the head upwards, an old Picasso – like vision. Incidentally, some species of 20 flatfish settle on the right side, others on left, and others on either side.

According to the passage, the ability of a bony flatfish to move its eyes around is ________.

A. average

B. weak

C. excellent

D. variable

Đáp án  C.

Keywords: bony flatfish, move eyes around.

Clue: “In evolution this problem was soleved by the lower eye “moving” around the other side. We see this process off moving around enacted in the development of every young bony flatfish”: Khi tiến hóa, vấn đề này được giải quyết bằng cách mắt dưới di chuyển xung quanh. Chúng ta nhìn thấy quá trình di chuyển này xuất hiện trong sự phát triển của mỗi cá con dẹt có xương.

 Do vậy, cá dẹt có xương khi phát triển đã có khả năng đảo một bên mắt xung quanh. Vì thế, “the ability of a bony flatfish to move its eyes around excellent: à Đáp án đúng là C. excellent.

Đáp án C

Key word: plaice.

Phân tích:

   A. have difficulties in swimming:  gặp khó khăn trong bơi lội – Sai vì ngay ở câu đầu tiên ta đã biết đây là một loài được hưởng lợi nhờ việc thân nó trở nên dẹt (benefit by being flat) à nó bơi rất giỏi nhờ được hưởng lợi thế tiến hóa.                             B. live near the surface:  sống ở gần mặt nước  - Sai  vì ngay ở câu đầu tiên ta đã biết đây là một loài sống ở đáy biển (live on the sea botton).

   C. have distorted heads: có đầu méo mó -  Đúng vì bài có đề cập đến việc hộp sọ của chúng bắt đầu phát triển theo một kiểu thời trang xoắn bất đối xứng. (the skull starts to grow in a strange asymmetrical twisted fashion)  

    D. have poor eyesight:  có mắt kém – Sai vì trong bài chỉ nói nó hay nằm nghiêng, một con mắt lúc nào cũng nhìn xuống cát và bởi vậy cái mắt đó là vô dụng (one eyes was always looking down into the sand and was effectively useless) à không phải là do mắt kém

Vậy đáp án là C. have distorted heads.

Đáp án D.

Key words: conversely

Clue: “They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely, fish such sas plaice, sole, and halibut have become flat in a different way” :  Trông chúng như thể đã bị dẹt nhưng vẫn đối xứng và giữ được thăng bằng. Ngược lại, những loài cá như cá chim, cá bơn, và cá chim lớn bị dẹt theo một phương thức khác”.

Vì thông tin hai câu là trái ngược nhau và được nối bằng “conversely” nên “conversely” là ngược lại hoặc trái lại.

Đáp án D. contrarily là đáp án đúng. Các đáp án còn lại không phù hợp:

   A. similarly: tương tự

   B. alternatively: hoặc

   C. inversely: đổi ngược về vị trí hoặc số lượng (không dùng để nối hai câu)

Key words: plaice.

Phân tích:

A. have difficulties in swimming: gặp khó khăn trong bơi lội – Sai vì ngay ở câu đầu tiên ta đã biết đây là một loài được hưởng lợi nhờ việc thân nó trở nên dẹt (benefit by being flat) → nó bơi rất giỏi nhờ được hưởng lợi thế tiến hóa.
