句子語法沒有錯(cuò),但不邏輯,
英語我們說 weather is fine/good/bad,等等
（天氣 好,不好,...）
一般不說“天氣熱” (the weather is hot)
但你可以說 It's hot today （今天很熱） .
至于新概念的句子,
“the weather's often cold in the north and windy in the east”
第一句改為
“It is often cold in the north and windy in the east”
比較邏輯
第二句
“our climate is not very good,but it's certainly interesting”
沒有錯(cuò),完全正確.
