The document summarizes Cook's (2011) comparison of L1 and L2 language learning, noting similarities in how first and second languages are acquired. It discusses factors like context, motivation, and mental capacity. Theories from scholars like Chomsky, Krashen, and Schumann are reviewed on topics such as innate language abilities, formal learning vs acquisition, and social/motivational influences. The evaluation finds the presentation clear and well-supported, though more research is needed on cultural/attitudinal impacts and how teachers can foster acquisition over just learning. Motivation, understanding one's native language, and using the target language in real contexts are important for L2 learning. Overall L1 and L2 acquisition share similarities
