IX. Read the text carefully, then do the tasks.

Large cities often have problems that small towns and rural areas do not have. Two of the biggest problems are heavy traffic and the pollution that cars create. Of course. Traffic problems and pollution are not only found in big cities. However, the higher populations and larger number of cars on the roads in cities can make the problems happen more often and with more noticeable effects.

One of the most common traffic problems the large cities have is congestion. As the population of a city increases, so does the number of cars on the road. Cities cannot always improve the number

and size of their roads and highways to keep up with the number of cars. The result is traffic congestion, or trafficjams.

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 from 4 to 8.

DRINKING AND DRIVING

The legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 milliliters of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, if you’ve just eaten and what sort of drinks you’ve had. Some people might reach their limit after only about three standard drinks.

In fact, your driving ability can be affected by just one or two drinks. Even if you’re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.

It takes about an hour for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking session in the evening you might find that your driving ability is still affected the next morning, or you could even find that you’re still over the legal limit. In addition, if you’ve had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit.

In a test with professional drivers, the more alcoholic drinks they had had the more certain they were that they could drive a test course through a set of moveable posts … and the less able they were to do it!

So the only way to be sure you’re safe is not to drink at all.

Alcohol is a major cause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More half of the people stopped by the police to take a breathalyzer test have a blood alcohol concentrate of more than twice the legal limit.

It is important to remember that driving after you’ve been drinking doesn’t just affect you. If you’re involved in an accident it affects a lot of other people as well, not least the person you might kill or injure

Alcohol is a major cause of road traffic accidents in that ___. 

A. more young men die in drink-related accidents than in any other way 

B. most drivers who die in these accidents have been drinking 

C. drinking affects people’s eyesight 

D. one in three drivers drink heavily

Giải thích:

Khi nào bạn có thể bị cảnh sát đưa ra tòa vì uống rượu và lái xe?

  A. Khi cảnh sát nhận ra rằng bạn đã uống rượu từ cách bạn lái xe.

  B. Chỉ khi xét nghiệm cho thấy bạn có 80mg cồn trong 100 ml máu.

  C. Khi bạn lái xe sau khi uống bất kỳ chút đồ uống có cồn nào.

  D. Khi bạn đã uống ít nhất ba ly trước khi lái xe.

Thông tin: Even if you’re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.

Tạm dịch: Ngay cả khi bạn ở dưới mức giới hạn pháp lý, bạn vẫn có thể bị đưa ra tòa nếu cảnh sát cho rằng việc lái xe của bạn bị ảnh hưởng bởi rượu.

Dịch bài đọc:

Giới hạn pháp lý trong lái xe sau khi uống đồ uống chứa cồn là 80 mg cồn trong 100 ml máu, khi được kiểm tra. Nhưng không có cách nào chắc chắn để cho bạn biết bạn có thể uống bao nhiêu trước khi bạn đạt đến giới hạn này. Nó thay đổi theo từng người tùy thuộc vào cân nặng, giới tính, vào việc bạn có vừa mới ăn không và loại đồ uống bạn đã uống. Một số người có thể đạt đến giới hạn của họ sau khi uống chỉ 3 ly bình thường.

Trên thực tế, khả năng lái xe của bạn có thể bị ảnh hưởng chỉ bằng một hoặc hai ly rượu. Ngay cả khi bạn ở dưới mức giới hạn pháp lý, bạn vẫn có thể bị đưa ra tòa nếu cảnh sát cho rằng việc lái xe của bạn bị ảnh hưởng bởi rượu.

Mất khoảng một giờ để cơ thể loại bỏ chất cồn trong một ly rượu bình thường. Vì vậy, nếu bạn có một buổi nhậu nhiều vào buổi tối, bạn có thể thấy rằng khả năng lái xe của bạn vẫn bị ảnh hưởng vào sáng hôm sau, hoặc thậm chí bạn có thể thấy rằng bạn vẫn còn vượt quá giới hạn pháp lý. Ngoài ra, nếu bạn đã có uống vài ly vào bữa trưa, một hoặc hai ly nữa vào buổi chiều tối cũng có thể đưa bạn vượt quá giới hạn pháp lý.

Trong một thử nghiệm với các tài xế chuyên nghiệp, họ càng uống nhiều đồ uống có cồn thì họ càng chắc chắn rằng họ có thể làm một bài kiểm tra lái xe qua những chiếc cột di động và ... họ càng ít có khả năng làm điều đó!

Vì vậy, cách duy nhất để chắc chắn rằng bạn an toàn là không uống chút nào cả.

Đồ uống có cồn là một nguyên nhân chính của tai nạn giao thông đường bộ. Cứ ba tài xế thì có một người thiệt mạng trong các vụ tai nạn đường bộ do có nồng độ cồn vượt quá giới hạn pháp lý, và tai nạn trên đường sau khi uống rượu là nguyên nhân gây tử vong lớn nhất ở nam thanh niên. Hơn một nửa số người bị cảnh sát dừng lại để kiểm tra hơi thở có nồng độ cồn trong máu cao hơn gấp đôi giới hạn pháp lý.

Điều quan trọng cần nhớ là lái xe sau khi bạn đã uống rượu không chỉ ảnh hưởng bản thân bạn. Nếu bạn gây ra một vụ tai nạn, nó ảnh hưởng đến rất nhiều người khác, đặc biệt là người mà bạn có thể làm chết hoặc làm bị thương

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 from 30 to 34.

A leading question among anthropologists is: what exactly led to the development of human cities? Basically, modern humans have existed on earth for over 100,000 years. Yet it is only in the last 8,000 years that they have begun to gather in significant numbers and form cities. Prior to that period, humans existed in small family or tribal groups, generally consisting of fewer than 100 individuals. What, then, led humans to make the dramatic shift from living in small groups to living in large, organized cities? It seems that the development of cities required a particular set of circumstances.

First, it required a minimum population density. For much of their early history, humans existed only in small numbers. This is due to the fact that early humans relied on hunting and gathering wild foods for their survival. Even the most fertile land would only support a relatively small number of predators, so it was not until humans began to practice agriculture that they were able to gather in large enough numbers to form cities.

Furthermore, the development of a city could only be possible if a large number of people shared a common language, culture and religion. Without such unifying factors, a cooperative, peaceful existence among large numbers of people would have been impossible.

Finally, it seems that early humans needed to be faced with a large problem, which one small group of individuals could not solve on its own. Only when large-scale cooperation was needed to overcome a problem would humans come together to form cities

Which of the following is NOT needed for the development of a city?

A. a shared culture 

B. people’s gathering 

C. peaceful existence 

D. large-scale collaboration

Tạm dịch: Hơn thế nữa, sự phát triển của một thành phố chỉ có thể xảy ra nếu một lượng lớn cư dân có chung một ngôn ngữ, văn hóa và tôn giáo. Nếu không có các yếu tố thống nhất như vậy, một tập thể, việc cùng chung sống hòa bình giữa những lượng lớn cư dân là không thể.

Chỉ khi cần phải hợp tác quy mô lớn để vượt qua vấn đề thì con người mới tập trung lại để tạo dựng những thành phố.

Dịch bài đọc:

Một câu hỏi hàng đầu giữa các nhà nhân chủng học là: chính xác điều gì dẫn đến sự phát triển của các thành phố của con người? Về cơ bản, con người hiện tại đã tồn tại trên trái đất hơn 100,000 năm. Tuy nhiên chỉ trong 8,000 năm đã qua thì họ mới bắt đầu tập trung với số lượng đáng kể và tạo dựng các thành phố. Trước thời kỳ này, con người tồn tại trong những gia đình nhỏ hoặc các nhóm bộ tộc, thường bao gồm ít hơn 100 cá nhân. Vậy điều gì, sau đó, dẫn dắt con người tạo ra sự thay đổi mạnh mẽ từ việc sống trong các nhóm nhỏ sang sống trong các thành phố lớn, có tổ chức? Dường như sự phát triển của các thành phố đòi hỏi một chuỗi cụ thể những hoàn cảnh.

Lúc đầu, nó đòi hỏi một mật độ dân số tối thiểu. Trong phần lớn lịch sử ban đầu của con người, con người chỉ tồn tại với các nhóm số lượng nhỏ. Điều này do thực tế con người thời kì đầu phụ thuộc vào việc săn bắn và hái lượm thức ăn hoang dã để sống sót. Ngay cả vùng đất màu mỡ nhất cũng chỉ hỗ trợ cho một số lượng động vật ăn thịt tương đối nhỏ, vì vậy mãi đến khi con người bắt đầu canh tác nông nghiệp thì họ mới có thể tập trung số lượng đủ lớn để tạo nên những thành phố.

Hơn thế nữa, sự phát triển của một thành phố chỉ có thể xảy ra nếu một lượng lớn cư dân có chung một ngôn ngữ, văn hóa và tôn giáo. Nếu không có các yếu tố thống nhất như vậy, một tập thể, việc cùng chung sống hòa bình giữa những lượng lớn cư dân là không thể.

Cuối cùng, dường như con người cần phải đối mặt với một vấn đề lớn hơn, cái mà một nhóm nhỏ cá nhân không thể tự giải quyết. Chỉ khi cần phải hợp tác quy mô lớn để vượt qua vấn đề thì con người mới tập trung lại để tạo dựng những thành phố
