2. Read the passage and underline the wrds that where, when, and why refer t.
where在定語從句中用作地點狀語，其先行詞須是表地點的名詞。如: This is the schl where I studied a few years ag.

as busy as a bee
Cmplete the paragraph with the animal idims abve.
If they’re rushing int smething and shuld wait and be patient, yu culd say “_________________”. Learning idims can be fun, especially when we cmpare them t Chinese equivalents. Take, fr example, “__________________________________ ” (peple d what they want and have fun when smene in authrity is absent) and “_________________________” (slve tw prblems with ne actin) – are there crrespnding idims in Chinese?
