課文詳注 Further notes on the text
1．It is a fine day today.今天天氣好。
句中的it是指天氣。又如：
Is it cold today? 今天冷嗎？
No, it isn't. 不，不冷。
2．some clouds，幾朵云。
some既可修飾可數(shù)名詞，也可修飾不可數(shù)名詞。如：some tables一些椅子（可數(shù)名詞），some milk一些牛奶（不可數(shù)名詞）。
3．There are some clouds in the sky, but the sun is shining.天空中飄著幾朵云，但陽(yáng)光燦爛。
這句是并列句，由兩個(gè)分句構(gòu)成，連詞but表明分句之間存在著對(duì)比及轉(zhuǎn)折關(guān)系。兩分句之間大多要用逗號(hào)，有時(shí)可不用逗號(hào)。
4．Mr. Jones is with his family.瓊斯先生同他的家人在一起。
句中with是介詞，表示“和……一起”。family是指“家里的人”或“家庭成員”。

句中的over有“穿過(guò)”的意思。又如：
The aeroplane is flying over the river.
飛機(jī)正在河上飛過(guò)。
The birds are flying over the house.
鳥(niǎo)兒在屋上飛過(guò)。
over還可表不“在……上方”（不接觸表面），如：
The sky is over our heads.
天空在我們頭頂上。
6．There are some boats on the river. 河上有幾艘船。
句中on意為“在……上面”（接觸表面）。又如：

句中under意為“在……下面（或下方）”。如：
There is a dog under the tree.
樹(shù)下有只狗。
ship一般指海洋中行駛的大船。boat一詞指河中行駛的小船。另外：aeroplane（英國(guó)英語(yǔ)），airplane（美國(guó)英語(yǔ)），飛機(jī)（正式用語(yǔ)）； plane，飛機(jī)（非正式用語(yǔ)）。語(yǔ)法 Grammar in use
現(xiàn)在進(jìn)行時(shí)（2）
