Read the following passage about Asia’s culture and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions

[I] Chemicals are present everywhere in our environment, some of which occur naturally, while others are the result of human activities. [II]. They are found in the air, water, and soil, and can have both positive and negative impacts on the ecosystem. Some chemicals, like nutrients, help support life by promoting plant growth [III]. However, others, especially synthetic chemicals such as pesticides, fertilizers, and industrial waste, can be harmful to both the environment and human health. [IV]

The widespread use of pesticides and fertilizers in agriculture has been a major cause of chemical pollution. When these chemicals are used improperly or excessively, they can wash into rivers, lakes, and oceans, leading to water pollution. This runoff can also contribute to the depletion of oxygen in water bodies, a process known as eutrophication. Eutrophication harms aquatic life, disrupting ecosystems and causing the death of fish and other organisms that rely on oxygen.

Toxic chemicals such as heavy metals (e.g., mercury and lead) pose additional threats to the environment and human health. These substances can accumulate in the food chain, starting from plants and animals in contaminated areas and eventually reaching humans. Long-term exposure to these chemicals can lead to serious health issues, including neurological disorders, cancer, and other chronic conditions. Many countries have established regulations to limit the use of harmful chemicals, but enforcement remains a challenge.

Efforts to reduce chemical pollution involve a combination of government regulations, technological innovations, and public awareness. Governments worldwide have introduced stricter rules on the use of hazardous chemicals and encouraged the development of eco-friendly alternatives. These regulations aim to limit the harmful impact of chemicals on the environment, encouraging industries to adopt safer practices. Environmental organizations play a vital role in monitoring chemical pollution, raising awareness, and advocating for cleaner technologies. They work closely with policymakers to ensure effective enforcement of environmental laws. While progress has been made, ongoing efforts are needed to address emerging challenges and ensure a safer and healthier environment for future generations.

According to paragraph II, which of the following is NOT a consequence of chemical pollution?

Công dụng thông báo thông tin cần thiết cho con người thực hiện theo lệnh của mạch điều khiển tín hiệu  là:

1. No matter who we are or where we are from, we only have 24 hours each day to get things done. Some people seem to make the most of their time, using it to achieve their goals and dreams. Others feel that life is passing them by and they aren’t accomplishing anything. If you are in the latter group, it is not too late to turn things around. By implementing a few simple hacks, you can start getting better results very quickly.

2. If you want to become more productive, it pays to learn about the Pareto principle (which is also known as the 80-20 rule). It states that for most tasks, 80 percent of the results we get come from 20 percent of the work we do. For example. 80 percent of the company sales usually come from 20 percent of customers. Therefore, the trick is to focus your efforts on the key 20 percent of actions that truly matter to greatly improve your results.

3. In some cases, people may be busy from morning to night but still seem to get nothing done. In this situation, the problem might be that clear goals haven’t been set. To fix this, set some time aside to list the things you want to achieve in life. Then, select the top three or four that you want to focus on for the next year. Look at your goals every night before bedtime and ask yourself what are the next actions to accomplish each day. Then, promise yourself that you will finish these tasks no matter how busy you get. If possible try completing the tasks first thing in the morning so you are assured of success.

4. Another common mistake regarding productivity is not considering our energy levels. If we try to work around the clock, we will eventually get tired and quit. Everyone needs time to sleep, eat, socialize with friends, and unwind from the stress of the day. To make sure you don’t burn out, be sure to schedule some time for breaks and fun activities into your schedule every day. Finally, no matter how difficult your goals may seem, remember the old saying that “a journey of a thousand miles begins with a single step”.
