Summary
We learn:
1. Vocabulary: land, African, rose, peony, lotus, butterfly, wing, frog, up to,
weigh, kg, ginkgo, believe, province, take a walk.
2. Sentence Patterns: Superlative forms of adjectives (e.g., the largest,
the most beautiful).
We can:
1. use superlative adjectives to describe people, animals, plants, and places;
2. understand and answer questions about descriptive passages using
superlatives.
如果把这种“比较”的眼光,放到我们自己身上呢?放到我们努力成长的过程中呢?
She sings more beautiful than me;
His English is the best in our class;
He plays basketball best in our school;
She can play piano;
……
Let’s think
在生活中,我们有时会忍不住拿自己和别人比。但问题在于,我们是否选择了合适的‘比较范围’和‘比较对象’?
更智慧的“比较”,是和自己比! 今天的我,比昨天的我进步了吗?这个月的努力,是否比上个月更投入?这才是真正有意义的最高级——“更好的自己”!
How can we compare ourselves correctly?
Write a short passage to describe your favourite plant or animal.
You should use the comparative and superlative forms of adjectives and adverbs.
