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

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 question.

        Most people start smoking when they are in their teens and are addicted by the time they reach adulthood. Some have tried to quit but have returned to cigarettes because smoking is such a strong addiction. It is a habit that is very difficult to break. There are many different reasons why people smoke.

        Three of the main reasons that young people smoke are to look mature, to be like their friends, and to experiment. Since teens see older people all around them smoking, especially their parents and relatives, they smoke to act older. If their friends or peers smoke, they may feel pressured into doing the same to be accepted. The last reason is the excitement of experimenting with something that is forbidden. In Massachusetts it is against the law for anyone under 18 years old to smoke. Usually parents do not allow their under age teens to smoke. Therefore, smoking becomes very attractive. It is exciting to get cigarettes and sneak away to smoke without being caught.

         Adults smoke for other reasons. They may have a lot of stress and pressures because of economic and personal problems. They may be unemployed or working but not making enough money to take care of themselves and their families. They may be homeless, or they may be dealing with alcohol or cocaine/heroin addictions. Some may be in bad marriages or relationships in which there is physical and/or verbal abuse. All these people may smoke to feel relaxed or to give them energy while going through a hard time.

        Whether young or old, some people smoke to control their weight. Smokers, on the average, weigh seven pounds less than non-smokers. Smoking reduces a person's appetite. It lessens his/her sense of taste and smell. This could be why ex-smokers gain weight after quitting cigarettes. Food tastes and smells so much better.

        Finally, there are people who say they love to smoke. Smoking gives them pleasure. It just makes them feel good.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the answer to each of the following questions.

All mammals feed their young. Beluga whale mothers, for example, nurse their calves for some twenty months, until they are about to give birth again and their young are able to find their own food. The behavior of feeding of the young is built into the reproductive system. It is a nonselective part of parental care and the defining feature of a mammal, the most important thing that mammals-- whether marsupials, platypuses, spiny anteaters, or placental mammals -- have in common.

But not all animal parents, even those that tend their offspring to the point of hatching or birth, feed their young. Most egg-guarding fish do not, for the simple reason that their young are so much smaller than the parents and eat food that is also much smaller than the food eaten by adults. In reptiles, the crocodile mother protects her young after they have hatched and takes them down to the water, where they will find food, but she does not actually feed them. Few insects feed their young after hatching, but some make other arrangement, provisioning their cells and nests with caterpillars and spiders that they have paralyzed with their venom and stored in a state of suspended animation so that their larvae might have a supply of fresh food when they hatch.

For animals other than mammals, then, feeding is not intrinsic to parental care. Animals add it to their reproductive strategies to give them an edge in their lifelong quest for descendants. The most vulnerable moment in any animal's life is when it first finds itself completely on its own, when it must forage and fend for itself. Feeding postpones that moment until a young animal has grown to such a size that it is better able to cope. Young that are fed by their parents become nutritionally independent at a much greater fraction of their full adult size. And in the meantime those young are shielded against the vagaries of fluctuating of difficult-to-find supplies. Once a species does take the step of feeding its young, the young become totally dependent on the extra effort. If both parents are removed, the young generally do not survive.

What can be inferred from the passage about the practice of animal parents feeding their young?

A. It is unknown among fish.

B. It is unrelated to the size of the young.

C. It is dangerous for the parents.

D. It is most common among mammals.
