A roundabout is a circular intersection where drivers travel in one direction around a central island.

The primary goal is to make traffic movement more (35) __________ than at traditional crossroads, reducing unnecessary waiting times and fuel consumption for drivers.

The system works because it promotes continuous movement. Rather than stopping at red lights, drivers approach the roundabout, slow down, and yield to vehicles already circulating. Drivers (36) __________ only enter the circle when there is a safe gap in traffic. Once a space is available, they can (37) __________ smoothly with the moving vehicles and proceed towards their exit without having to stop completely.

(42) __________, roundabouts offer a smart solution to modern traffic management. By reducing delays and improving safety, they represent a significant advancement over older intersection designs. While they require drivers to be more engaged, the benefits for the community are clear.

In today's digital age, especially after periods of online learning in Vietnam, communicating with teachers via email has become standard. However, many students make the mistake of writing to their teachers with the same informal style they use for texting friends. This can create a negative impression and lead to misunderstandings. Learning the proper etiquette for digital communication is a crucial skill, not just for school, but for your future career. A well-written email shows respect and maturity, ensuring your message is taken seriously.

Why does it matter so much? Imagine you have an urgent question about the upcoming high school entrance exam. A clear, respectful, and well-structured email is more likely to receive a prompt and helpful response from your teacher. Conversely, an email written in all caps, with slang and no clear subject line, might be confusing or even overlooked. Therefore, understanding how to communicate professionally is essential for effective learning. It directly influences the quality of the support you receive.

Crafting a proper email is simple if you follow a few basic rules. First, always use a clear and specific subject line. Instead of “question,” write something like “Question Regarding Math Homework - Nguyen Minh Anh, Class 9B.” Second, start with a formal greeting, such as “Dear Mr. Long” or “Dear Ms. Hoa.” Third, in the body of the email, state your purpose clearly and politely. Provide all necessary context so your teacher understands your request without needing to ask for more information. Finally, end with a polite closing like “Sincerely,” or “Thank you,” followed by your signature, which should include your full name and class.

Equally important is knowing what to avoid. Never use slang, internet acronyms (like 'lol' or 'idk'), or emojis. These are considered unprofessional in an academic setting. Avoid writing in all capital letters, as this is seen as shouting. Furthermore, respect your teacher’s time; don't send emails late at night and expect an immediate reply. If you mention an attachment, double-check that you have actually attached the file. Students often forget this simple step. They then have to send an embarrassing follow-up email, causing a delay.

Mastering email etiquette is more than just a school requirement; it's a fundamental life skill. The habits you build now will help you communicate effectively in university and your future workplace. A professional email reflects your seriousness as a student and paves the way for positive and productive relationships with your instructors.
