Hybrid cars are becoming more common on our roads. They are special because they cleverly (35) __________ two different power sources: a traditional gasoline engine and a modern electric motor. This dual system is managed by a smart computer that automatically decides which power source to use, and when. The main goal is to maximize efficiency, which helps to save fuel and reduce harmful emissions.

When you start a hybrid car or drive at low speeds, it usually relies only on its electric motor. This is especially useful in (36) __________ heavy city traffic or when looking for a parking space.

For teenagers across Vietnam, the pressure of the high school entrance exam, or 'Thi vào 10', is immense. In today's digital age, the challenge is not just mastering subjects like Math and Literature, but also conquering a relentless enemy: digital distraction. A single notification from TikTok or a message on Facebook can instantly break a student's concentration, making effective studying feel almost impossible. This constant battle for focus has led many students to look for a modern solution to a modern problem.

The solution has arrived in the form of 'focus mode' applications and browser extensions. These tools are designed with a simple but powerful purpose: to create a digital environment free from interruptions. Apps like Forest, Freedom, or Cold Turkey allow users to temporarily block access to specific websites and applications that they find most distracting. By setting a timer—for example, for a 45-minute study session—a student can ensure that they will not be disturbed by social media or online games until their dedicated study time is over.

The effectiveness of these tools goes beyond simply blocking websites. They create a powerful psychological commitment. When you actively turn on a focus app, you are sending a clear signal to your brain that it is time to concentrate. This conscious decision makes it harder to give in to the impulse to check your phone. Instead of passively letting distractions happen, you take active control over your digital space. Furthermore, many of these focus applications are designed to be user-friendly and integrate smoothly with a student's existing digital devices. Because they are so accessible, students can easily make them a part of their daily study routine.

Interestingly, this trend is not just about individual discipline; it has a strong social component. Many Vietnamese students preparing for 'Thi vào 10' are forming online study groups on platforms like Discord. Within these groups, it's common for members to announce a 'study sprint'. Everyone agrees to activate their focus apps for a set period, creating a sense of shared commitment and accountability. This transforms a potentially isolating activity into a collaborative effort, making it easier for everyone to stay on track.

Ultimately, technology is a double-edged sword. It can be the source of our biggest distractions, but it can also provide the tools to defeat them. For the modern student, learning to use technology to manage focus is not just a helpful trick—it's a fundamental skill. Mastering this 'superpower' is as crucial as mastering any academic subject for achieving success in high-stakes exams and beyond.
