FITNESS TRENDS

[I] Reformer Pilates is an advanced and more intense variation of traditional Pilates. [II] Since this type of equipment isn’t something you would typically have at home, you’ll need to visit a specialized Pilates center to try it. [III] While it might look easy at first, don’t be fooled - by the end of the session, your thighs will be burning, and you might struggle to walk up or down stairs for a few days afterward. [IV] This workout pushes your body to its limits, providing a more challenging experience than standard Pilates, and many find it an effective way to build both strength and flexibility.

Trampolining is another popular fitness trend, and although it may seem like child's play, it’s actually a highly effective workout. Jumping up and down on a trampoline can leave you feeling exhausted after just a few minutes. Surprisingly, it’s even better for heart health than running, while also improving coordination and helping to reduce stress levels. Trampolining is gaining widespread popularity, with new centers popping up that feature as many as 150 trampolines. These facilities offer options for everyone: you can enjoy 'freejumping,   where you bounce without an instructor, or pay for professional lessons to learn the best techniques and get the most out of your workout. Many people are discovering that trampolining combines fun and fitness in a way that makes staying active much more enjoyable.

If you're someone who is typically active but feeling down or emotionally drained, Dynamic Running Therapy might be just what the doctor ordered. This trend involves running with a therapist, combining the benefits of physical exercise with talk therapy. Though these sessions are often more expensive than typical therapy sessions because of the professional fees, they offer significant advantages. Running while talking helps distract you from any discomfort, allowing you to cover longer distances, and creates a relaxed, open environment that can make it easier to talk compared to the usual therapist’s office setting.

According to paragraph 2, which of the following is NOT a benefit of Trampolining?

Data privacy means ensuring that our personal information is kept safe and used responsibly by others. In today’s digital world, where information spreads easily, it’s more important than ever to protect our personal data. This highlights the importance of privacy laws.

Laws about data privacy vary globally. For example, in Europe, the General Data Protection Regulation (GDPR) grants individuals rights such as accessing their data, asking for it to be deleted, and knowing how it’s used. Similarly, the California Consumer Privacy Act (CCPA) provides specific rights about personal information to people in California. Knowing these laws helps people understand their rights and what companies must do to keep their data safe. When using websites or apps, it’s essential to read their privacy policies. Emily Davis, a cybersecurity expert, stresses, “Reading and understanding privacy policies allows individuals to make informed decisions about sharing their personal information.”.

To boost your online safety, experts suggest using strong, unique passwords for each account and not reusing them. Enabling two-factor authentication when possible adds an extra layer of security. Equally important, be careful with emails, texts, or calls asking for personal information or money. Scammers often pretend to be real organizations. Always check before giving out personal details or clicking on links from unknown sources. Keep your devices updated with the latest software and security patches to protect against cyber threats. Using trusted antivirus software can also lower the risk of attacks. Privacy advocate Michelle Carter advises, “Being mindful of data sharing and regularly reviewing app permissions helps minimize unnecessary exposure of personal information.”.

Understanding your rights and taking steps to protect your personal information online are essential in today’s interconnected world. By learning about privacy laws, being careful about sharing information, and using strong security measures, you can control your digital presence and keep your privacy safe. Remember, protecting personal data is something we all need to do together to create a safer and more respectful online environment.

Đọc đoạn trích dưới đây và trả lời các câu hỏi:

     Nhà mẹ Lê là một gia đình một người mẹ với mười một người con. Bác Lê là một người đàn bà quê chắc chắn và thấp bé, da mặt và chân tay nhăn nheo như một quả trám khô. Khi bác mới đến phố, ai ai cũng chú ý đến đám con của bác: mười một đứa, mà đứa lớn mới có mười bảy tuổi! Đứa bé nhất hãy còn bế trên tay.

     Mẹ con bác ta ở một căn nhà lá. Chừng ấy người chen chúc trong một khoảng rộng độ bằng hai chiếc chiếu, có mỗi một chiếc giường nan gãy nát. Mùa rét thì trải ổ rơm đầy nhà, mẹ con cùng nằm ngủ trên đó, trông như một cái ổ chó, chó mẹ và chó con lúc nhúC. Đối với người nghèo như bác một chỗ ở như thế cũng tươm tất lắm rồi. Nhưng còn cách kiếm ăn? Bác Lê chật vật, khó khăn suốt ngày cũng không đủ nuôi từng ấy đứa con. Từ buổi sáng tinh sương, mùa nực cũng như mùa rét, bác ta đã phải trở dậy để đi làm mướn cho những người trong làng. Những ngày có người mướn ấy, tuy bác phải làm vất vả, nhưng chắc chắn buổi tối được mấy bát gạo và mấy đồng xu về nuôi lũ con đói đợi ở nhà.[...] Trong ngày hè nóng nực, con bác Lê đứa nào cũng lở đầu – bác ta bảo là một cái bệnh gia truyền từ đời ông tam đại – nên bác lấy phẩm xanh bôi cho chúng nó. Trông mẹ con bác lại giống mẹ con đàn gà, mà những con gà con người ta bôi xanh lên đầu cho khỏi lẫn. Người phố chợ vẫn thường nói đùa bác Lê về đàn con đông đúc ấy.

Read the following passage about Traveling 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.

          Traveling and exploring new places is an exciting way to experience different cultures and expand one’s horizons. Whether it’s a short trip to a neighbouring town or a long journey to a foreign country, stepping out into the world offers numerous benefits. It allows individuals to gain new perspectives, meet diverse people, and create lasting memories. Additionally, traveling can enhance personal growth and provide a sense of adventure and fulfillment.

          One of the key advantages of traveling is the opportunity to learn about different cultures. By immersing oneself in a new environment, travellers can gain a deeper understanding of local customs, traditions, and lifestyles. This cultural exchange fosters mutual respect and appreciation among people from different backgrounds. Moreover, experiencing different cultures can challenge preconceptions and broaden one’s worldview.

          Traveling also promotes personal development. Facing unfamiliar situations and overcoming challenges can boost confidence and adaptability. Travelers often find themselves  navigating new cities, trying unfamiliar foods, and communicating in foreign languages. These experiences can enhance problem-solving skills and resilience. Furthermore, the sense of accomplishment from successfully managing a trip can lead to increased self-esteem and a greater sense of independence.

          Another benefit of traveling is the chance to disconnect from the routine of everyday life. Exploring new places provides a break from the usual responsibilities and stresses. This can be refreshing and rejuvenating, allowing individuals to return home with a renewed sense of energy and perspective. Travel can also foster creativity by exposing individuals to new sights, sounds, and ideas.

          Despite its benefits, traveling can also present challenges. Planning a trip requires time and effort, and unexpected situations can arise. However, these challenges can be viewed as opportunities for growth and learning. With careful planning and a positive mindset, the rewards of traveling far outweigh the difficulties.

Which of the following is NOT mentioned as a benefit of traveling?

Read the following passage about education in Nepal 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 31 to 40. 

Fashion in the 1960s reflected the cultural and political upheaval of the time. The hippie and counterculture movement gave rise to accessories like Pocahontas-style headbands and medallions worn around the neck. Hippies wore long, loosely fitting clothing, often in natural fabrics. Hemlines rose as Mary Quant popularized the miniskirt and hot pants in her lines for JC Penney. And mod fashion, with brightly colored space-age geometric patterns, shift dresses and colored tights became the mainstream. Both miniskirts and mod-shift dresses were worn with knee-high go-go boots.

[A] During the 1970s, the loose-fitting hippie clothes of the prior decade gave way to exotic fabrics and bell-bottom jeans for men and women. Hemlines continued to rise and hot pants continued their popularity, reflecting the flashy style of the decade. However, the 1970s also saw the popularity of a longer hemline, from mid-calf to ankle-length. [B] Women wore peasant-style clothing, especially blouses with off-the-shoulder necklines and lace trim, with their jeans or skirts. [C] Disco fashion emerged, featuring bright patterns and tightly fitting clothing meant to show off the body. Platform shoes elevated their wearer, male or female, anywhere from two to four inches or more. [D]

The 1980s saw another fashion upheaval. Angst-ridden punks wore Dr. Marten and steel-toed army boots, chains, tartan patterns, and bondage pants. Punks focused more on their hair during this period, dying, teasing and chopping their hair into asymmetric styles that seemed to defy gravity. Women—and men—experimented with heavy eyeliner in a variety of colors. Women wore neon colors, jelly shoes, tight jeans, leggings, leg warmers and oversized sweatshirts. Menswear-inspired looks also became popular for both sexes. Men wore ‘power suits,’ named so for their price, which made these suits a reflection of the wealth of the wearer. Women’s jackets featured big shoulder pads that made the shoulders appear higher and larger, similar to the male silhouette.

1990’s fashion was far more subdued than the garish, wild styles of the 1980s. Bands like Nirvana influenced the grunge look, which featured rock-concert tee shirts under plaid flannel shirts, jeans and long, greasy hair. Overalls were worn by both sexes, either with one or both shoulder straps unhooked. The punk style of the 1870s and 1980s evolved into the goth fashion trend, which featured black clothing, black boots and studded bracelets in the style of bands like Nine Inch Nails and Marilyn Manson.

What can be inferred from accessories like Pocahontas-style headbands?
