Analyze vocabulary shades of meaning for questions 5 to 7

Using the Vocabulary Definitions knowledge point

• Question 5: "Eagerly" indicates high speed and intensity, making "gulped" the appropriate choice over "sipped".
• Question 6: A light bulb is made of thin glass, which bursts into many tiny pieces when dropped, so "shattered" is more precise than "broke".
• Question 7: "So fast" indicates eating quickly and in large amounts, which corresponds to "gobble" rather than "nibble".

Analyze vocabulary shades of meaning for questions 8 and 9

Using the Vocabulary Definitions knowledge point

• Question 8: Having a brand-new bike stolen is an extreme situation, making the stronger emotion "furious" more fitting than "mad".
• Question 9: "Hoping she wouldn't wake the baby" requires a very quiet action, making "tapped" the correct choice over "pounded".
