1.on the way在途中;即將到來
【課文原句】Unusual animal behaviour,for example,can indicate whether it’s cold,wet weather that’s on the way or a hot,dry period.
例如,不尋常的動(dòng)物行為,可以表明即將到來的是寒冷潮濕的天氣,還是炎熱干燥的時(shí)期。
【詞匯精講】on the way在該句子中表示“即將到來”,同時(shí),它還有“在路上”的含義。后面常加to+地點(diǎn),表示“在去……的路上”。

通知說颶風(fēng)即將到來。

所以,為了準(zhǔn)確可靠的預(yù)測(cè),最好檢查一份官方的科學(xué)報(bào)告。

【詞匯精講】consist of表示“由……組成”,不用于進(jìn)行時(shí)態(tài)和被動(dòng)語態(tài),但是可以用其動(dòng)詞-ing形式作定語。
