B. Các công ty sơn phải hạn chế lượng chì trong sơn.

C. Các công ty sơn không bắt buộc phải hạn chế lượng chì trong sơn.

D. Các công ty sơn luôn tuân thủ các hạn chế về lượng chì trong sơn.

Thông tin: Although American paint companies today must comply with strict regulations regarding the amount of lead used in their paint, this source of lead poisoning is still the most common and most dangerous.

Dịch bài đọc:

Ngộ độc chì ở trẻ em là một vấn đề sức khoẻ nghiêm trọng. Đã gọi là sơn thì liều lượng cao hay thấp đều có thể gây hậu quả nghiêm trọng. Trẻ tiếp xúc với chì ở liều lượng cao thường bị tổn thương lâu dài về thần kinh, thiểu năng trí tuệ, mù mắt, thậm chí mất mạng. Nhiễm chì mức độ thấp thì có thể thiểu năng trí tuệ ch t ít, kém tập trung, dễ xao lãng, kết quả học tập kém và có vấn đề về hành vi ứng xử.

Đây không phải là một mối quan tâm mới. Ngay từ đầu năm 1904, tình trạng trẻ bị nhiễm chì đã được cho là có liên quan tới sơn có chì. Hạt chì li ti trong sơn sẽ thấm vào máu khi trẻ nuốt phải những mảnh sơn, vữa bị tróc hoặc bụi sơn trong cát. Chì cũng có thể xâm nhập cơ thể qua bụi bặm trong nhà, do trẻ cắn móng tay, mút tay hoặc nhai đồ chơi và những món đồ nào sơn bằng sơn có chì. Mặc dù hiện nay các hãng sơn của Mỹ phải tuân thủ các quy định nghiêm ngặt về lượng chì dùng trong sơn, nhưng sơn vẫn là nguồn gây nhiễm độc chì phổ biến nhất, nguy hiểm nhất. Đặc biệt là trẻ sống trong những ngôi nhà cũ đổ nát thì càng dễ bị nhiễm chì hơn nữa.

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 36 to 43.

The difference between the nuclear family and the extended family is that a nuclear family refers to a single basic family unit of parents and their children, whereas the extended family refers to their relatives such as grandparents, in-laws, aunts and uncles, etc. In many cultures, and particularly indigenous societies, the latter is the most common basic form of social organization.

A nuclear family is limited, according to Kristy Jackson of Colorado State University, to one or two parents (e.g. a father and mother) and their own child, or children, living together in a single house or other dwellings. In anthropology, they only must be related in this fashion; there is no upper or lower limit on the number of children in a nuclear family.

The extended family is a much more nebulous term, but in essence refers to kin or relations not covered by the above definition. In historical Europe and Asia as well as in Middle Eastern, African, and South American Aboriginal cultures, extended family groups were typically the most basic unit of social organization, The term can differ in specific cultural settings, but generally includes people related in age or by lineage.

Anthropologically, the term "extended family" refers to such a group living together in a household, often with three generations living together (grandparents, parents, and children) and headed in patriarchal societies by the eldest man or by some other chosen leadership figure. However, in common parlance, the term "extended family" is often used by people simply to refer to their cousins, aunts, uncles, and so on, even though they are not living together in a single group.

What can be inferred from the reading passage?

A. Indigenous communities have been completely eradicated all over the world.

B. In the future, all extended families will be replaced by nuclear ones.

C. Anthropology is a science concerning human race and its development.

D. Couples with no children can't be defined as families.

D. Không thể định nghĩa cặp vợ chồng không có con là gia đình.

Thông tin: Anthropologically, the term “extended family” refers to such a group living together in a household, often with three generations living together (grandparents, parents, and children) and headed in patriarchal societies by the eldest man or by some other chosen leadership figure.

Dịch bài

Sự khác biệt giữa gia đình hạt nhân và gia đình mở rộng là gia đình hạt nhân chỉ một đơn vị gia đình cơ bản gồm cha mẹ và con cái của họ, trong khi gia đình mở rộng bao gồm cả nguwoif thân của họ như ông bà, bố mẹ, cô dì chú bác…Trong nhiều nền văn hóa, và đặc biệt là các xã hội bản địa, loại hình thứ hai là hình thức phổ biến nhất của tổ chức xã hội.

Theo Kristy Jackson thuộc Đại học Bang Colorado, gia đình hạt nhân có giới hạn, cho một hoặc cả hai cha mẹ (ví dụ như cha và mẹ) và một đứa con của họ, hoặc nhiều đứa, sống chung trong một ngôi nhà hoặc nhiều ngôi nhà khác. Trong nhân chủng học, họ chỉ có liên quan theo cách này; không có giới hạn trên hoặc dưới đối với số con trong một gia đình hạt nhân.

Gia đình mở rộng là một thuật ngữ mơ hồ hơn nhiều, nhưng về bản chất đề cập đến thân nhân hoặc quan hệ không được định nghĩa ở trên. Trong lịch sử châu Âu và châu Á cũng như ở các nền văn minh thổ dân ở Trung Đông, châu Phi và Nam Mỹ, các nhóm gia đình mở rộng thường là đơn vị cơ bản nhất của tổ chức xã hội. Thuật ngữ có thể khác nhau trong các bối cảnh văn hóa cụ thể, nhưng nói chung bao gồm những người liên quan đến tuổi tác hoặc huyết thống.

Về mặt nhân chủng học, thuật ngữ “gia đình mở rộng” dùng để chỉ một nhóm người sống chung trong một hộ gia đình, thường có ba thế hệ cùng sống chung với nhau (ông bà, cha mẹ và con cái) và đứng đầu trong các xã hội gia trưởng bởi người đàn ông nhiều tuổi nhất hoặc bởi người lãnh đạo được lựa chọn. Tuy nhiên, theo cách hiểu chung, thuật ngữ “gia đình mở rộng” thường được mọi người sử dụng để chỉ họ hàng, cô dì, chú bác,…mặc dù họ không sống cùng nhau trong một nhóm.

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 38 to 42.

(1) Though Edmund Halley was most famous because of his achievements as an astronomer, he was a scientist of diverse interests and great skill. In addition to studying the skies, Halley was also deeply interested in exploring the unknown depths of the oceans. One of his lesser-known accomplishments that were quite remarkable was his design for a diving bell that facilitated exploration of the watery depths.

(2) The diving bell that Halley designed had a major advantage over the diving bells that were in use prior to his. Earlier diving bells could only make use of the air contained within the bell itself, so divers had to surface when the air inside the bell ran low. Halley’s bell was an improvement in that its design allowed for an additional supply of fresh air that enabled a crew of divers to remain underwater for several hours.

(3) The diving contraption that Halley designed was in the shape of a bell that measured three feet across the top and five feet across the bottom and could hold several divers comfortably; it was open at the bottom so that divers could swim in and out at will. The bell was built of wood, which was first heavily tarred to make it water repellent and was then covered with a half-ton sheet of lead to make the bell heavy enough to sink in water. The bell shape held air inside for the divers to breathe as the bell sank to the bottom.

(4) The air inside the bell was not the only source of air for the divers to breathe, and it was this improvement that made Halley’s bell superior to its predecessors. In addition to the air already in the bell, air was also supplied to the divers from a lead barrel that was lowered to the ocean floor close to the bell itself. Air flowed through a leather pipe from the lead barrel on the ocean floor to the bell. The diver could breathe the air from a position inside the bell, or he could move around outside the bell wearing a diving suit that consisted of a lead bell-shaped helmet with a glass viewing window and a leather body suit, with a leather pipe carrying fresh air from the diving bell to the helmet.

It is NOT stated in the passage that Halley’s bell _____.

A. was completely enclosed

B. was wider at the top than at the bottom

C. could hold more than one diver

D. was made of tarred wood

Environmental pollution is one of the impacts of human activities on the Earth. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution disturbs our ecosystem and the balance in the environment. Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light Let us discuss the causes and effects of air pollution on mankind and the environment as a whole.

Air pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.

The effects of air pollution are evident too. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like sulfur dioxide (SO2) and nitrogen oxide (NO) can cause acid rain.

The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be caused by air pollution.

The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.

Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer.

(Source: https://goo.gl/RpdPw3)

According to paragraph 5, air pollution contributes to the greenhouse effect which can lead to

A. global warming

B. polar ice melting

C. increase in CO2 in the environment

D. global warming, polar ice melting, rise of sea levels and danger for people.
