Volunteering offers many of the same social benefits, with the added bonus of helping others and developing useful skills to put on your CV. Plus, students are in a unique position to help, suggests Tom Fox. "They can take their enthusiasm and excitement for opportunities and share their passions, subject knowledge and experience with people." The idea of giving up time for nothing might seem impractical at first, especially once the pressures of study and coursework or exams begin to mount up. However, Michelle Wright, CEO of charity support organization Cause4, suggests seeing volunteering as a two-way street. "I think it is fine for undergraduates to approach volunteering as a symbiotic relationship where doing good is just one part of the motivation for reaching personal and professional goals."
Katerina Rudiger, head of skills and policy campaigns at the Chartered Institute of Personnel and Development (CIPD), says: "Volunteering can be a valuable way of gaining that experience, as well as building confidence, broadening your horizons, becoming a better team player and developing those all- important 'employability skills' such as communication and decision making." Amanda Haig, graduate HR manager, agrees that volunteering can help your employment prospects. "Volunteering can demonstrate positive personality traits and skill sets, such as proactivity, and teamwork," she says.
A positive side-effect of volunteering is improving your time at university by getting involved in the local community. Leaving the student bubble can make your time as an undergraduate much more varied. At Bath Spa University, more than 1,000 students volunteered over the past year, doing everything from working on local environmental projects to helping in schools or assisting the elderly. ”Quite often there can be a divide between students and permanent residents," says students' union president Amy Dawson, "but if students invest a little time now, they will be giving something back to the local community and will reap the benefits in the future."
“You might also find that volunteering helps your studies if you choose the right program. At Lancaster, volunteering is linked into academic modules in some cases", explains Fox. "This has multiple wins. Students get to apply their learning in the classroom and share their interests with children in local schools or community organizations, while schools gain skilled students with a passion for a subject that enthuses their pupils."

Personality traits and skill sets include____________.

Read the following passage about the Designing Spaces That Connect Us to Nature 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.

Biophilic design has been turning heads and winning hearts by incorporating natural elements into our living and working spaces. This approach recognizes our innate connection to nature and how it affects our well-being. Studies show that exposure to natural light, plants, and natural materials can reduce stress and improve productivity. Many modern architects now integrate gardens, water features, and large windows into their designs. These elements help create environments where people can thrive both mentally and physically. As one designer put it, "We're bringing the outside in to help people feel at home in their skin."

The benefits of biophilic design extend beyond aesthetics. [I] Hospitals with views of nature report faster patient recovery times. Office buildings with natural elements see decreased absenteeism and increased worker satisfaction. [II] Schools incorporating biophilic principles observe improved student concentration and academic performance. [III] Even retail spaces benefit, with customers spending more time and money in naturally-designed environments. These practical advantages explain why biophilic design is gaining momentum across various sectors. [IV]

Implementing biophilic design doesn't require elaborate renovations. Simple changes like adding houseplants, using natural materials, or rearranging furniture to maximize natural light can make significant differences. Even artificial representations of nature, such as nature photography or recordings of birdsong, provide some benefits. The key is creating spaces that stimulate our senses in ways that remind us of natural environments. This approach works in urban apartments, suburban homes, and rural settings alike. As cities grow denser, these natural connections become increasingly valuable for maintaining our psychological health.

Looking ahead, biophilic design will likely become standard practice rather than a luxury option. Climate change concerns are pushing architects to create buildings that not only connect with nature but also protect it. Living walls that purify air, rooftop gardens that reduce energy consumption, and materials that sequester carbon are becoming more common. These innovations represent a shift from merely appreciating nature to actively participating in its preservation. By designing spaces that honor our biological need for natural connection, we create environments that support both human and planetary health for generations to come.

The word “rearranging” in paragraph 3 is OPPOSITE in meaning to _________.

Read the following passage about Innovation Driven by Environmental Need 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.

Green startups have emerged as forces for positive environmental change. These companies create sustainable solutions for urgent ecological challenges. Unlike traditional businesses prioritizing profits, green startups balance financial goals with environmental responsibility. Many were founded by young entrepreneurs who witnessed environmental degradation and felt compelled to act. Their mission extends beyond making money; they aim to heal our planet while building successful businesses.

Eco-friendly startups have grown across various sectors. From renewable energy and sustainable agriculture to zero-waste products, these companies revolutionize how we interact with our environment. GreenWave developed ocean farming requiring no fertilizers while capturing carbon. Notpla created edible packaging from seaweed as a plastic alternative. These innovations show how creativity and environmental consciousness produce extraordinary results. Their success proves sustainability and profitability can coexist.

Funding for green startups has increased in the past decade. Investors recognize supporting environmentally responsible businesses is both ethical and financially prudent. Venture capitalists have established funds dedicated to sustainable startups, providing capital to scale operations. Government grants have become more accessible to entrepreneurs developing green technologies. Despite positive developments, green startups still face regulatory hurdles and competition from established industries resistant to change.

The future looks promising for environmental businesses as consumers shift toward sustainable products. Studies show modern consumers, particularly younger generations, will pay premium prices for eco-friendly alternatives. This trend creates fertile ground for green startups to thrive. As climate concerns intensify, demand for innovative environmental solutions will grow stronger. Green startups are positioned to meet this demand while driving positive change, demonstrating business innovation and environmental stewardship can create a sustainable world.

In which paragraph does the writer mention green startups are working in many different industries with impressive innovations?

Read the following passage about news 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.

[I] Wildlife conservation refers to the efforts made to protect and preserve wild animal species and their habitats. [II] It is crucial for maintaining biodiversity, which plays a vital role in ecosystem stability and health (Smith & Jones, 2018). [III] Unfortunately, many species are threatened due to habitat destruction, poaching, and climate change, making conservation efforts more urgent than ever. [IV]

One of the primary reasons for wildlife conservation is the preservation of biodiversity. A diverse range of species contributes to ecosystem services, such as pollination, water purification, and climate regulation. The loss of a single species can disrupt these services and lead to ecological imbalances. For instance, the decline of pollinators like bees has serious implications for food production and agriculture (Global Biodiversity Outlook, 2020).

Moreover, wildlife conservation has significant economic benefits. Many communities depend on ecotourism, which relies on healthy wildlife populations and intact ecosystems. According to a study by the World Wildlife Fund (WWF), ecotourism can generate billions of dollars in revenue, providing jobs and supporting local economies (WWF, 2021). Protecting wildlife not only safeguards natural resources but also creates sustainable livelihoods for local populations.

However, effective wildlife conservation requires a collaborative approach. Governments, non-governmental organizations, and local communities must work together to implement policies and strategies that promote conservation efforts. Community-based conservation initiatives, where local people actively participate in protecting their natural resources, have shown promising results. These initiatives empower communities and ensure that conservation efforts are tailored to local needs and contexts (Bennett & Dearden, 2014).

The word "collaborative" in paragraph 4 is CLOSEST in meaning to ____.

(18)_________, such as food, shelter, and education. In many parts of the world, (19)_________, with families trapped in a cycle of deprivation. While poverty is a complex issue, it is often connected to factors like unemployment and lack of access to education. These factors make it hard for individuals to escape the cycle and improve their lives. To address poverty, governments and organizations must create sustainable policies that focus on education, healthcare, and employment opportunities.

Another pressing issue is gender inequality. In many countries, women still face discrimination in areas like employment and education, limiting their opportunities for personal and economic growth. Even in developed nations, women earn less than men for doing the same work. (20)_________, as people demand equal rights and opportunities for all genders. Moreover, gender inequality can also affect women's health and safety, (21)_________.

Finally, environmental degradation, like pollution and climate change, is a growing global concern. Environmental damage, (22)_________, especially in poorer regions, often affects them the most. The increasing frequency of natural disasters, caused by climate change, is also putting immense pressure on vulnerable populations. Tackling these issues requires a collective effort from both individuals and governments. Only through cooperation and sustainable practices can we hope to create a more equitable and livable world for future generations.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 40.

Parents of a Tokyo elementary school are up in arms at being asked to pay 730 dollars for their child's school uniform. A public elementary school in Tokyo's upmarket Ginza district has decided to adopt new school uniforms designed by the luxury Italian designer Armani. The bespoke uniforms, which include a hat and bag, are priced at over 80,000 (730 dollars) each. Parents are angry at the school's decision and are protesting at what they view as the exorbitant price for a uniform of an eight-year-old child. The school said it wanted a designer uniform that represented the rich area of Ginza. School officials visited top department stores and decided to ask the fashion brand Armani to design the uniform.

The expensive uniform has created such a fuss that it has been discussed in Japan's parliament. One lawmaker said that since the school is public and not private, "a certain price range needs to be considered". Finance Minister Taro Aso said. "Clearly it's expensive. It would be tough if a student could not afford to pay for it." Japan's education minister said steps would be taken to ensure the financial burden placed on parents for uniforms, "would not be excessive". Twitter users said young children are not interested in designer clothes. The school principal said. "With humility, I take the criticism that the explanation has been insufficient and not well-timed. I will go on explaining carefully to those concerned."

What does the passage mainly discuss?
