Grammar spotlight: expressing contrast and nuance

To help your students move from simple sentences to more complex, sophisticated descriptions of psychological states, focus on the following two grammar points. These will help them bridge the gap between B1 and B2 proficiency.

Using contrastive linkers for complex ideas

Students often rely on “but” to connect ideas. At the B2 level, encourage the use of more formal contrastive linkers to better distinguish between OCD and OCPD.

• While / whereas: These are excellent for highlighting the fundamental differences between the two conditions.
  • Example: “While people with OCD often recognize their behavior as excessive, individuals with OCPD typically view their rigidity as the correct way to function.”
• On the other hand: Use this phrase to introduce a contrasting perspective after a full statement.
  • Example: “OCD behaviors are often ego-dystonic, meaning they feel like unwanted intruders. On the other hand, OCPD traits are often ego-syntonic, feeling more like a natural part of the person’s character.”
• In contrast: This is a strong, formal transition for written work or presentations.
  • Example: “OCD involves specific, repetitive rituals; in contrast, OCPD is characterized by a generalized need for perfection and control.”

Modal verbs of necessity and deduction

Because this lesson involves analyzing behavior, students need to express rules, degrees of certainty, and recommendations.

• Degrees of obligation (must vs. have to vs. should): Use these to discuss how traits might impact a person’s life.
  • Example: “A person with OCPD feels they must have total control over their environment to feel secure.”
• Deduction (must be, might be, can’t be): These are perfect for the “speaking practice” section where students interpret personality traits.
  • Example: “If someone spends hours checking the stove, that must be a source of great anxiety for them.”
  • Example: “This level of perfectionism might be adaptive in surgery, but it can’t be healthy in a flexible team environment.”

Reading and listening (20 min)

• Students read the transcript silently (or key excerpts) for 5-7 minutes.
