Sometimes people add to what they say even when they don't talk. Gestures are the "silent language" of every culture. We point a finger or move another part of the body to show what we want to say. It is important to know the body language of every country or we may be misunderstood. In the United States, people greet each other with a handshake in a formal introduction. The handshake must be firm. If the handshake is weak, it is a sign of weakness or unfriendliness. Friends may place a hand on the other's arm or shoulder. Some people, usually women, greet a friend with a hug.

Space is important to Americans. When two people talk to each other, they usually stand about two and a half feet away and at an angle, so they are not facing each other directly. Americans get uncomfortable when a person stands too close. They will move back to have their space. If Americans touch another person by accident, they say, "Pardon me." or "Excuse me." Americans like to look the other person in the eyes when they are talking. If you don't do so, it means you are bored, hiding something, or are not interested. But when you are stare at someone, it is not polite. For Americans, thumbs-up means yes, very good, or well done. Thumbs down means the opposite. To call a waiter, raise one hand to head level or above. To show you want the check, make a movement with your hands as if you are signing a piece of paper. It is all right to point at things but not at people with the hand and index finger. Americans shake their index finger at children when they scold them and pat them on the head when they admire them. Learning a culture's body language is sometimes confusing. If you don't know what to do, the safest thing to do is to smile

A. shows his rudeness to you

Giải thích:

Từ “accident” ở đoạn 2 gần nghĩa nhất với .

  A. cơ hội                  

B. sự bất hạnh/ rủi ro

C. vận xui                   

D. thảm họa

by accident = by chance: vô tình, tình cờ

=> accident = chance

Thông tin: If Americans touch another person by accident, they say, "Pardon me." or "Excuse me."

Tạm dịch: Nếu người Mỹ vô tình chạm vào người khác, họ nói "Thứ lỗi cho tôi" hoặc "Tôi xin lỗi"

Dịch bài đọc:

Đôi khi mọi người bổ sung thông tin ngay cả khi họ không nói chuyện. Cử chỉ là "ngôn ngữ im lặng” của mọi nền văn hóa. Chúng ta chỉ tay hoặc di chuyển một bộ phận khác của cơ thể để biểu lộ những gì muốn nói. Hiểu được ngôn ngữ cơ thể của mỗi quốc gia là vô cùng quan trọng, nếu không chúng ta có thể bị hiểu lầm. Ở Mỹ, trong một cuộc giới thiệu chính thức, mọi người chào nhau bằng cách bắt tay. Cái bắt tay phải chặt. Nếu bắt tay hời hợt, đó được cho là dấu hiệu của sự yếu kém hoặc không thân thiện. Bạn bè có thể khoác tay lên cánh tay hoặc vai của nhau. Một số người, thường là phụ nữ, chào bạn bè với một cái ôm.

Khoảng cách rất quan trọng đối với người Mỹ. Khi hai người nói chuyện với nhau, họ thường đứng cách nhau khoảng 2,5 feet (75cm) và không thẳng nhau, do đó, họ không trực tiếp đối diện nhau. Người Mỹ thấy khó chịu khi một người đứng quá gần mình. Họ sẽ lùi lại để tạo không gian cho bản thân. Nếu người Mỹ vô tình chạm vào người khác, họ nói "Thứ lỗi cho tôi" hoặc "Tôi xin lỗi". Người Mỹ thích nhìn vào mắt người khác khi họ đang trò chuyện. Nếu bạn không làm như vậy, nó có nghĩa là bạn cảm thấy chán, che giấu điều gì đó hoặc là không quan tâm họ. Nhưng cũng thật bất lịch sự nếu bạn nhìn chằm chằm vào một ai đó. Đối với người Mỹ, giơ ngón tay cái lên có nghĩa là đồng ý, rất tốt hoặc làm tốt. Chỉ ngón tay cái xuống dưới có nghĩa ngược lại. Để gọi người phục vụ, hãy giơ một tay lên ngang đầu hoặc cao hơn. Để thể hiện bạn muốn thanh toán, hãy di chuyển tay như thể bạn đang ký giấy. Chỉ vào mọi thứ đều nhưng không được chỉ vào người khác bằng tay và ngón tay trỏ. Người Mỹ lắc ngón tay trỏ khi chỉ vào trẻ em lúc họ mắng chúng và xoa đầu chúng khi họ khen ngợi chúng. Học ngôn ngữ cơ thể của một nền văn hóa đôi khi khó hiểu. Nếu bạn không biết phải làm gì, điều an toàn nhất để làm là mỉm cười

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

It is estimated that over 99 percent of all species that have existed have become extinct. What causes extinction? When a species is no longer adapted to a changed environment, it may perish. The exact causes of a species' death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be able to adapt. Food resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately, in the death of a species.

The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions, many species became extinct at the same time- a mass extinction. One of the best-known examples of mass extinction occurred 65 mmion years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago, when approximately 95 percent of all species died. Mass extinction can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affecting even organisms not living in the oceans. Such a change would probably lead to a mass extinction.

One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intensive every 26 million years. This periodic extinction might be due to intersection of the Earth's orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species' survival may have nothing to do with its ability or inability to adapt. If so, some of evolutionary history may reflect a sequence of essentially random events. 

According to the passage, it is believed that the largest extinction of a species occourred _______. 

A. 26 million years ago 

B. 250 million years ago 

C. 225 million years ago
