To best develop a second language, a student should:

• A. Focus exclusively on grammar drills.
• B. Continue to develop his first language.
• C. Translate all content into his first language.
• D. Stop developing his first language.

Answer: (B)

Developing a second language is best supported by maintaining and enriching the first language. When a student keeps developing L1, they already have solid basics in vocabulary, grammar, and literacy to draw from. These skills transfer to the new language, making it easier to learn more complex structures and to understand texts and conversations. Keeping L1 active also builds confidence and motivation, since the student can express ideas across languages and use their existing knowledge as a bridge to L2.

Focusing only on grammar drills misses the real-world use of language and often doesn't give enough practice with speaking, listening, and meaningful communication. Translating everything into L1 slows immersion in L2 and reinforces dependence on the first language rather than encouraging thinking and expressing ideas directly in the new language. Stopping development of the first language can hinder cognitive flexibility, identity, and the ability to switch between languages when needed.

So, continuing to develop the first language provides a strong foundation that supports faster and more robust second-language growth.
