Một công ty đa quốc gia thực hiện chế độ nghỉ Tết Nguyên Đán dành cán bộ công nhân viên Việt Nam theo nguyên tắc như sau:

- Thứ nhất, tuân thủ Luật Lao động và tạo điều kiện tốt nhất cho người dân được nghỉ ngơi, kỳ nghỉ bắt đầu vào hai hôm trước Mùng Một Tết, và kéo dài thêm ba ngày Tết, tổng cộng năm ngày.

- Thứ hai, nếu năm ngày nghỉ Tết trùng một hay hai ngày nghỉ khác thì sẽ nghỉ bù tương ứng ngay sau ngày nghỉ Tết cuối cùng theo Luật. Nếu ngay sau đó lại là thứ bảy hay chủ nhật thì bù tiếp vào sau ngày nghỉ cuối cùng.

- Thứ ba là nguyên tắc bắc cầu. Nếu có một ngày làm việc kẹt giữa các ngày nghỉ, thì cho nghỉ luôn ngày đó, và làm bù vào ngày nghỉ cuối tuần gần nhất. Không bắc cầu nếu có từ hai ngày kẹt giữa trở lên. Nếu kẹt hai ngày không liên tục, thì sẽ nghỉ bắc cầu cả hai, và làm bù hai ngày nghỉ cuối tuần gần nhất, nhưng mỗi tuần chỉ làm bù một ngày.

- Thứ tư là không nghỉ Tết quá 9 ngày. Theo đó, năm nào vượt 9 ngày, thì cắt các ngày thừa cuối, nhưng doanh nghiệp sẽ bố trí cho người lao động nghỉ bù vào các tuần làm việc thứ bảy kế tiếp sau nghỉ Tết.

Biết tuần làm việc thứ bảy và tuần nghỉ làm thứ bảy đan xen nhau.

Nếu Tết Nguyên Đán năm 2024, các cán bộ công nhân viên Việt Nam bắt đầu kì nghỉ vào 29 tháng Chạp (tức thứ 5 tuần làm việc thứ bảy) thì tổng số ngày nghỉ của cán bộ công nhân viên Việt Nam là bao nhiêu ngày?

Read the passage carefully

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”.

What should we do in order to achieve our goals?

Read the following passage about How Failures Led to Breakthroughs and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Many important discoveries happened because of mistakes and unexpected accidents. Alexander Fleming found penicillin when he left his laboratory messy before going on holiday. After vacation, he saw mold growing on his experiment plate. Fleming noticed this mold killed bacteria around it very effectively. This fortunate accident later saved millions of lives around the world. Scientists call finding valuable things by chance "serendipity," which happens often in research.

The Post-it Note began as a mistake that seemed useless at first. In 1968, Spencer Silver tried making a strong glue for 3M company but created a weak one instead that didn't stick permanently. Nobody knew what to do with this disappointing result for several years. Then his colleague Arthur Fry realized this "failure" could make perfect bookmarks that wouldn't damage pages when removed. This weak adhesive eventually became one of the most popular office products worldwide, changing how people work.

In cooking, many favorite foods came from kitchen errors and quick substitutions. Ruth Wakefield invented chocolate chip cookies when she ran out of baker's chocolate and used broken pieces of semi-sweet chocolate instead. She thought they would melt completely in the dough, but they kept their shape during baking. Potato chips were created when chef George Crum made extremely thin potatoes to annoy a customer who repeatedly complained about thick fries. Surprisingly, the customer loved them and ordered more!

These fascinating stories teach us that mistakes can lead to new opportunities and unexpected innovations. Thomas Edison said about his many failed light bulb attempts, "I haven't failed. I've just found 10,000 ways that don't work." This positive attitude shows we should see errors as valuable learning chances. Smart people don't fear making mistakes in their work; they fear missing opportunities to learn from them and discover something amazing.

Read the following passage about endangered languages and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questionsfrom 31 to 40.

[I] Social media has become a dominant force in modern communication, offering a range of benefits and challenges. [II] It has revolutionized the way people interact, share information, and even form relationships. [III] While these platforms offer opportunities for connection and expression, they also have their drawbacks. [IV] For instance, excessive use of social media has been linked to a range of negative effects, including mental health issues, social isolation, and decreased productivity. [V] However, when used responsibly, social media can also offer a variety of positive outcomes, such as the ability to stay connected with loved ones, network professionally, and access valuable information and resources.

One of the major benefits of social media is its ability to keep people connected. For example, individuals who live far apart can maintain close relationships through regular communication on these platforms. Social media also facilitates professional networking, allowing users to connect with potential employers or clients, and enabling companies to promote their products and services to a global audience. Additionally, platforms like Facebook, Twitter, and Instagram provide a space for people to share ideas, opinions, and creative work, fostering a sense of community and collaboration.

Despite these advantages, there are serious concerns about the negative impact of social media, particularly on mental health. Studies have shown that excessive social media use can contribute to feelings of anxiety, depression, and loneliness. This is often attributed to the unrealistic portrayals of life that are commonly shared on these platforms, leading to comparisons that can make individuals feel inadequate or left out. Furthermore, constant exposure to negative news or online bullying can exacerbate these feelings and contribute to long-term psychological stress.

Another issue with social media is its potential to distract people from their daily responsibilities. With notifications constantly popping up and endless streams of content to scroll through, individuals may find it difficult to focus on tasks such as work, school, or personal obligations. This can result in decreased productivity and a lack of attention to important matters.

Ultimately, the impact of social media depends on how it is used. If individuals are mindful of their usage patterns and take steps to limit their time on these platforms, they can enjoy the benefits of staying connected and informed without the negative consequences. Parents, educators, and mental health professionals can also play a role in helping young people develop healthy habits and manage their social media use effectively.

According to passage, which of the following is NOT a benefit of social media? 

Read the following passage about online dating and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Psychologists have found many advantages and disadvantages to online dating. Among the many criticisms aimed at online dating, the most severe concern is its effects on people's self-esteem and mental health.

Swipe left or right is the main feature of popular dating apps, where users quickly look at profiles. However, this system is criticized for being superficial. A study showed that users often feel less satisfied with their appearance. Jessica Strübel found that after a while, users begin to feel less like unique, special individuals and more like they're disposable. This feeling leads to users becoming increasingly sensitive about their looks and bodies, heightening self-consciousness. Dating apps also added to the idea that there's always something better around the corner, which further pressures users into trying to appear more attractive.

Dating apps not only harm self-esteem but also alter perceptions of relationships. By accelerating the dating process, these apps encourage poor social behavior. For instance, it's not unusual for people to ignore "likes" and messages or to lose interest and cut off communication. This behavior would have been considered extremely rude in the past. But with online dating, it is a common reality.

Furthermore, thirty-five percent of users actually reported feeling pessimistic about dating. Only twenty-eight percent of surveyed users reported feeling hopeful after using a dating site or app.

According to paragraph 2, all of the following are problems with dating apps EXCEPT _____.
