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.

Birds have evolved many physical attributes that contribute to their flying ability. Wings are important, but adjustable tails, large hearts and light bones play critical roles.

To fly, birds, like airplanes, move air across their wings. Wings are designed so that air above the wings is forced to move faster than air below the wing. This creates higher pressure under the wings, called lift, which pushes the bird up. Different wing types evolved for different ways of flying. Prolonged flight requires long wings and an ability to soar. Other birds need superior maneuverability. Finches and sparrows

have short, broad wings. Faster birds, like hawks, have built-in spoilers that reduce turbulence while flying. This allows a steeper angle of attack without stalling.

Tails have evolved for specialized use. The tail acts like a rudder helping birds steer. Birds brake by spreading out their tails as they land. This adaptation allows them to make sudden, controlled stops-an essential skill, since most birds need to land on individual branches or on prey.

Flight takes muscle strength. If body builders has wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and provide the necessary oxygen to the muscles. The breast muscle accounts for 15 percent of the bird’s body weight. On pigeons, it accounts for a third of their total body weight.

Birds carry no excess baggage; they have hollow feathers and hollow bones with struts inside to maintain strength, like cross beams in a bridge. Birds fly to find prey, escape predators, and attract mates-in other words, to survive

What is the main idea of the passage? 

A. Wings are the most important physical attribute of birds

B. Different wing styles evolved for different types of flight

C. Birds have many specialized features that aid in their survival

D. Birds fly for many reasons

Birds have evolved many physical attributes that contribute to their flying ability. Wings are important, but adjustable tails, large hearts and light bones play critical roles.

To fly, birds, like airplanes, move air across their wings. Wings are designed so that air above the wings is forced to move faster than air below the wing. This creates higher pressure under the wings, called lift, which pushes the bird up. Different wing types evolved for different ways of flying. Prolonged flight requires long wings and an ability to soar. Other birds need superior maneuverability. Finches and sparrows

What does the author imply about the body builders having wings?

A. If they flapped their wings, they could fly a little

B. If they had wings, their muscles would be strong enough for flight

C. If they had wings, their hearts would still not be large for flight

D. Their wings would total 15 percent of their body weight

Tác giả hàm ý gì về những lực sĩ có cánh?

  A. Nếu họ vỗ cánh, họ có thể bay một chút.

  B. Nếu họ có cánh, cơ bắp của họ sẽ đủ khỏe để bay.

  C. Nếu họ có cánh, trái tim của họ sẽ vẫn không lớn để bay được.

  D. Đôi cánh của họ sẽ chiếm 15% trọng lượng cơ thể.

Thông tin: If body builders has wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and provide the necessary oxygen to the muscles.

Tạm dịch: Nếu lực sĩ có cánh, họ vẫn không thể vỗ đủ mạnh để rời khỏi mặt đất. Loài chim có trái tim lớn, chuyên biệt đập nhanh hơn nhiều so với trái tim con người và cung cấp oxy cần thiết cho cơ bắp.

Dịch bài đọc:

Chim đã phát triển nhiều thuộc tính vật lý để có được khả năng bay. Đôi cánh rất quan trọng, nhưng đuôi điều chỉnh được, trái tim lớn và xương nhẹ đóng vai trò quyết định.

Để bay, chim, cũng giống như máy bay, di chuyển không khí trên đôi cánh của chúng. Cánh được thiết kế sao cho không khí phía trên cánh buộc phải di chuyển nhanh hơn không khí bên dưới cánh. Điều này tạo ra áp lực lớn hơn ở dưới cánh, được gọi là lực nâng, đẩy chim lên. Các loại cánh khác nhau sẽ phát triển các cách bay khác nhau. Chuyến bay kéo dài đòi hỏi đôi cánh dài và khả năng bay vút lên. Các loài chim khác cần khả năng hoạt động mạnh hơn. Chim hoa mai và chim sẻ có đôi cánh ngắn và rộng. Những con chim nhanh hơn, như diều hâu, có tấm lái ngang được tích hợp sẵn giúp giảm nhiễu loạn trong khi bay. Điều này cho phép một góc độ tấn công dốc hơn mà không bị chao đảo.

Đuôi đã phát triển để sử dụng chuyên dụng. Đuôi hoạt động giống như một bánh lái giúp chim điều chỉnh hướng. Chim phanh lại bằng cách xòe đuôi khi chúng hạ cánh. Sự thích nghi này cho phép chúng dừng đột ngột nhưng có kiểm soát - một kỹ năng thiết yếu, vì hầu hết các loài chim cần phải đậu trên các nhánh cây riêng lẻ hoặc trên con mồi.

Chuyến bay mất sức lực của cơ bắp. Nếu lực sĩ có cánh, họ vẫn không thể vỗ đủ mạnh để rời khỏi mặt đất. Chim có trái tim lớn, chuyên biệt đập nhanh hơn nhiều so với trái tim con người và cung cấp oxy cần thiết cho cơ bắp. Cơ ngực chiếm 15% trọng lượng cơ thể của chim. Trên chim bồ câu, nó chiếm một phần ba tổng trọng lượng cơ thể của chúng.

Chim không mang theo hành lý quá mức; chúng có lông rỗng và xương rỗng với các thanh chống bên trong để duy trì sức lực, giống như xà ngang trong cây cầu. Chim bay để đến tìm con mồi, thoát khỏi kẻ săn mồi và thu hút bạn tình - nói cách khác là để sống sót

Do you know that some animals are camouflaged? This means their color is the same as the colors around them. Some camouflaged animals hide in seaweed, rocks, and sand. Look at the photo on the left. This looks like seaweed, but it’s not! It’s the leafy seadragon. It hides in the seaweed. It's the same color as seaweed. Like the seaweed, its body is also in the shape of a leaf. Look at the photo below. This is a stonefish. It hides on the sand, near rocks. It looks like a rock. Where are its eyes and its mouth?
