Tower cranes are a common sight in any city with new construction projects. They are the tall machines that stand over new buildings, looking like giant metal birds. Their primary job is the vertical transportation of heavy materials, such as steel beams and concrete blocks, from the ground to the upper floors of a structure. Without them, building skyscrapers would be nearly impossible.

The crane has several key parts. The most noticeable is the mast, which is the vertical tower that gives the crane its height. As the building gets taller, new sections are added to the mast, allowing the crane to grow with it. (21) __________ process is fascinating, as the crane essentially builds itself higher using a special climbing frame.

On top of the mast sits the slewing unit, which allows the machine to rotate. Extending from this unit is the long horizontal arm called the jib. This is the part that carries the load. At the other end, there are large concrete counterweights. These are crucial for balance. Without these heavy blocks, the crane (22) __________ simply tip over when lifting a heavy load. The operator must (23) __________ careful attention to the weight limits.

Of all the machinery on a modern construction site, the tower crane is often the tallest. Its great height and long reach make it an incredibly efficient tool. The operator, who sits in a small cab at the top of the mast, has a unique view of the entire project. Not only do they need excellent coordination, but they also require a deep understanding of physics and safety procedures.

Overall, the tower crane is more than just a machine; it is a symbol of urban growth and engineering achievement. Its ability to lift incredible weights to great heights with precision is what makes the construction of today's impressive city skylines possible. They are truly (24) __________ tools for any major building project.

In today’s digital age, students often find themselves juggling textbooks with a constant barrage of online notifications. Whether it’s a ping from a messaging app, a new post on social media, or an endless stream of videos, the internet, while a valuable resource, can quickly become a significant source of distraction. This challenge has led to the rise of "focus mode" tools – productivity apps and browser extensions designed to help users block out digital noise and concentrate on the task at hand, transforming how we approach online learning. [I]

These innovative tools operate by creating a distraction-free digital environment. When activated, they can block access to specified websites, silence app notifications, or even limit the usage of certain applications for a set period. Imagine setting a timer for an hour, during which your social media feeds are inaccessible and phone notifications are muted. [II]

For Vietnamese students, particularly those preparing for high-stakes exams like the "Thi vào 10" entrance exam, unwavering focus is paramount. Many rely on digital tools for research and collaborative study groups on platforms like Discord. While these foster learning, they also carry distraction risks. Integrating focus apps ensures that even when engaging with online resources, the primary goal – effective learning – remains undisturbed. This gives them a critical edge in a highly competitive academic landscape. [III]

As a 14-15 year old, you know firsthand how tempting it can be to switch from studying algebra to scrolling through TikTok or checking Facebook. These digital interruptions aren't just annoying; they break your concentration, making it harder to absorb and recall information. Learning to harness technology to combat these digital invaders is a modern superpower. By proactively using focus apps, you take control of your digital environment, transforming potential distractions into a disciplined study zone, ensuring your study time is truly productive. [IV]

Embracing "focus mode" isn't merely about blocking websites; it's about cultivating a healthier, more intentional relationship with technology. It encourages students to be mindful of their study habits and actively create an optimal learning environment, whether at home or in a library. Experiment with different apps to find what works best, set specific study intervals, and commit to using these tools consistently. Developing this digital discipline will not only help you excel in current exams but also equip you with invaluable productivity skills for your future academic and professional journeys.
