Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions

[I] A newborn baby can see, hear and feel. By the age of five, a child can talk, ride a bike and invent imaginary friends. How does this development happen? [II]We don't understand the way language, thinking and planning develop very well. [III]Now scientists are using new technology to ‘see’ into children's brains. And they are discovering new information about the way a baby's brain develops. [IV]

A study in 2010 showed that children who were afforded more focus often gained an edge in IQ. The brain of a newborn infant contains nearly a hundred billion neurons. This number is comparable to that of an adult's brain. As they mature, an infant assimilates information through the sensory modalities of sight, hearing, smell, taste, and touch. This information fosters intricate connections between different regions of the brain. By the age of three, there are approximately a hundred trillion synaptic connections.

One experiment looked at images of babies' brains while they were listening to different sounds. The sounds were in different sequences. For example, one sequence was mu-ba-ba. This is the pattern ‘A-B-B’. Another sequence was mu-ba-ge. This is the pattern ‘A-B-C’. The images showed that the part of the brain responsible for speech was more active during ‘A-B-B’ patterns. This shows that babies can tell the difference between different patterns. This experiment is interesting because sequences of words are important to grammar and meaning. Compare two sentences with the same words in a different order: ‘John killed the bear’ is very different from ‘The bear killed John.’ So babies are starting to learn grammatical rules from the beginning of life.

Researchers also know that babies need to hear a lot of language in order to understand grammar rules. But there is a big difference between listening to television, audiobooks or the internet, and interacting with people. One study compared two groups of nine-month-old American babies. One group watched videos of Mandarin Chinese sounds. In the other group, people spoke the same sounds to the babies. The test results showed that the second group could recognize different sounds, however, the first group learned nothing. The scientist, Patricia Kuhl, said this result was very surprising. It suggests that social experience is essential to successful brain development in babies.

The word “recognize” in paragraph 4 is OPPOSITE in meaning to:

Read the following passage about beginning a lifelong journey 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.

Lifelong learning is the continuous pursuit of knowledge and skills throughout a person's life. In today's world, where technology is evolving rapidly, lifelong learning is essential for both personal growth and career development. But just how does one go about becoming a lifelong learner?

The first step in becoming a lifelong learner is to develop a growth mindset. This means believing that your abilities can be developed through hard work, dedication and commitment. Embrace challenges, view mistakes as opportunities to learn, and be open to new ideas and perspectives. Adopting a growth mindset will help you approach learning with a positive attitude and a desire to improve.

Setting achievable goals is also an important part of lifelong learning. Goals give direction and motivation to your learning journey. First, identify areas of interest and choose specific skills or knowledge that you want to develop. Second, break your goals down into smaller, more manageable tasks and track your progress. Finally, celebrate your accomplishments along the way to stay motivated.

People learn in different ways, so it's also essential that you find the methods that work best for you. You can do this by trying out a variety of different learning methods, such as reading, watching videos, attending lectures and engaging in hands-on practice. At the same time, you should also experiment with different learning tools and techniques until you find what works best for you. Becoming a lifelong learner is a continuous process that requires dedication and effort. Developing a growth mindset, setting achievable goals, and using a variety of learning methods are essential steps to becoming a successful lifelong learner. By embracing learning as a lifelong journey, you will continue to grow, develop new skills, and stay relevant in today's ever-changing world.

Read the following passage about lifelong learning 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] Lifelong learning is the ongoing, voluntary, and self-motivated pursuit of knowledge for personal or professional development (Knowles, 2020). [II] This concept emphasizes that learning does not stop after formal education, but rather continues throughout an individual's life, adapting to changing circumstances and needs. [III] In today’s fast-paced world, where technology and job markets evolve rapidly, lifelong learning has become increasingly essential. [IV]

One of the primary benefits of lifelong learning is its ability to enhance employability. Individuals who engage in continuous education are more likely to keep their skills relevant and competitive in the job market. According to a report by the World Economic Forum (2021), over 50% of employees will need reskilling due to technological advancements in the coming years. Lifelong learners are better equipped to adapt to these changes, making them more attractive candidates for employers.

Moreover, lifelong learning contributes to personal fulfillment and mental well-being. Engaging in new learning experiences can stimulate the brain, foster creativity, and improve cognitive function. Research indicates that individuals who pursue learning opportunities throughout their lives tend to report higher levels of happiness and life satisfaction (Smith & Johnson, 2019). Whether it is taking a course, learning a new language, or picking up a new hobby, the process of acquiring knowledge can be enriching and enjoyable.

In addition, lifelong learning promotes social engagement and community involvement. Participating in educational programs or community workshops can foster connections with others who share similar interests. This social aspect of learning can enhance one's sense of belonging and support networks, which are crucial for mental health (Jones, 2022).

Overall, lifelong learning is not just an individual responsibility; it requires support from educational institutions, employers, and communities to create an environment conducive to continuous education. By fostering a culture of learning, society can better prepare individuals for the challenges of the future and ensure that everyone has the opportunity to thrive.
