A. Các công ty sơn không còn có thể sử dụng chì trong sơn.

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 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

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 43 to 50

Pollution emitted in industrial areas represents a threat to human health and the surrounding natural resources. We have a tendency to believe that the production processes are the only source of environmental damage, and often forget about the possible long-term effects of harmful production practices. We may think that the closure of these huge industrial areas would improve the quality of the environment. Unfortunately, this ignores the threat of the remaining waste, which is abandoned and poorly stored. It represents an even bigger danger because it stands neglected as it degrades and leaks into the earth without any control at all.

Changes in the water chemistry due to surface water contamination can affect all levels of an ecosystem. It can affect the health of lower food chain organisms and, consequently, the availability of food up through the food chain. It can damage the health of wetlands and damage their ability to support healthy ecosystems, control flooding, and filter pollutants from storm water runoff. The health of animals and humans are affected when they drink or bathe in contaminated water. In addition water-based organisms, like fish and shellfish, can pile up and concentrate contaminants in their bodies. When other animals or humans eat these organisms, they receive a much higher dose of contaminant than they would have if they had been directly exposed to the original contamination.

Contaminated groundwater can badly affect animals, plants and humans if it is removed from the ground by manmade or natural processes. Depending on the study of rocks of the area, groundwater may rise to the surface through springs or seeps, flow sideways into nearby rivers, streams, or ponds, or sink deeper into the earth. In many parts of fhe world, groundwater is pumped out of the ground to be used for drinking, bathing, other household uses, agriculture, and industry.

Contaminants in the soil can harm plants when they take up the contamination through their roots. Eating, breathing in, or touching contaminated soil, as well as eating plants or animals that have piled up soil contaminants can badly affect the health of humans and animals.

Air pollution can cause breathing-related problems and other bad health effects as contaminants are absorbed from the lungs into other parts of the hody. Certain air contaminants can also harm animals and humans when they contact the skin. Plants rely on breathing for their growth and can also be affected by exposure to contaminants moved in the air.

According to the passage, the industry is likely to be thought as ____.

A. a danger to the environment

B. the only source of pollution

C. the utmost harmful activity

D. a threat to human health
