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 different types of flatfish and they have evolved in very separate ways. The skates and rays, relatives of the sharks, have become flat in what might be called the obvious way. Their bodies have grown out sideways to form great “wings”. They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely, fish such as 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” then they are wide. They use their whole, vertically flattened bodies as swimming surfaces, which undulate through the water as they move. Therefore, when their ancestors migrated 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 solved by the lower eye “moving” around the other side. We see this process of 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, and old Picasso – like vision. Incidentally, some species of 20 flatfish settle on the right side, others on the 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 solved by the lower eye “moving” around the other side. We see this process of 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.” → Đáp án đúng là C. excellent.

Đáp án C.

Key words: skates and rays, examples.

Clue: The skates and rays, relatives of the sharks, have become flat in what might be called the obvious way. Their bodies have grown out sideways to form great “wings”. They look as though they have been flattened but have remained symmetrical: Những chiếc giày trượt và cá voi, những người họ hàng của cá mập, đã trở nên dẹt (có thể được gọi một cách rõ ràng. Cơ thể của chúng đã phát triển sang hai bên để tạo thành những bộ “cánh” tuyệt vời. Chúng trông như thể chúng đã được làm phẳng nhưng vẫn giữ được đối xứng

Phân tích:

A. become asymmetrical: trở nên xoắn đối – Sai vì loài cá này đối xứng kép.

B. appear to fly: có thể bay – Sai vì những chiếc cánh ở đây để trong ngoặc kép, không phải giống cánh thật.

C. have spread horizontally: trải rộng sang ngang – Đúng. “Spread” là trải rộng dài, bài khóa đề cập đến những chiếc cánh lớn.

D. resemble sharks: trông giống cá mập – Sai vì loài cá đuối này chỉ có họ hàng với cá mập, ngoại hình của chúng không giống cá mập.

Vậy câu trả lời đúng là C. have spread horizontally.

Đáp án B.

Key words: this.

Clue: “…when their ancestors migrated 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”: … khi tổ tiên của chúng di cư đến thềm lục địa đã nằm ngả về một phía thay vì nằm bằng bụng. Tuy nhiên, điều này làm dấy lên vấn đề khiến một mắt của chúng luôn nhìn xuống dưới cát và gần như là vô dụng.

“Điều này” ở đây là việc loài cá này nằm ngả về một bên.

A. the migration of the ancestors: Sự di cư của tổ tiên của chúng: Sai.

B. the practice of lying on one side: Việc tập nghiêng về một phía: Đúng.

C. the problem of the one eye looking downwards: Vấn đề mắt nhìn xuống dưới: Sai.

D. the difficulty of the only one eye being useful: Khó khăn trong việc chỉ có một mắt nhìn được: Sai.

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 as 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: đối ngược về vị trí hoặc số lượng (không dùng để nối hai câu)

Ex: Bond yields move inversely to market price: Lợi tức trái phiếu đi ngược lại với giá thị trường.

According to the passage, fish such as plaice _______.

A. have difficulties in swimming

B. live near the surface


 

C. have distorted heads

D. have poor eyesight

Đáp án C.

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.

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 bottom).

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 eye was always looking down into the sand and was effectively useless) → không phải là do mắt kém.

Vậy đáp án là C. have distorted heads.

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 23 to 29.

        For more than six million American children, coming home after school means coming back to an empty house. Some deal with the situation by watching TV. Some may hide. But all of them have something in common. They spend part of each day alone. They are called “latchkey children”. They are children who look after themselves while their parents work. And their bad condition has become a subject of concern.

      Lynette Long was once the principal of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was constantly telling them to put the keys inside shirts. There were so many keys; it never came to my mind what they meant.” Slowly, she learned that they were house keys.

        She and her husband began talking to the children who had keys. They learned of the effect working couples and single parents were having on their children. Fear was the biggest problem faced by children at home alone. One in three latchkey children the Longs talked to reported being frightened. Many had nightmares and were worried about their own safety

       The most common way latchkey children deal with their fears is by hiding. They may hide in a shower stall, under a bed or in a closet. The second is TV. They often turn the volume up. It’s hard to get statistics on latchkey children, the Longs have learned. Most parents are slow to admit that they leave their children alone.

One thing that the children in the passage share is that___________.

A. they all wear jewelry

B. they spend part of each day alone

C. they all watch TV

D. they are from single-parent families

Đáp án B.

Clue: But all of them have something in common. They spend part of each day alone: Nhưng tất cả đều có một cái gì đó chung. Chúng đều dành một phần của mỗi ngày một mình.

A. They all wear jewelry: Tất cả chúng đều đeo trang sức

B. They spend part of each day alone: Chúng dành một phần của mỗi ngày một mình

C. They all watch TV: Tất cả chúng đều xem TV

D. They are from single -parent families: Chúng đều xuất thân từ những gia đình bố/mẹ đơn thân.

Do đó đáp án chính xác là đáp án B
