at present意为“现在；眼下”。present是一个名词、形容词，也是动词。作为名词和形容词，其读音为[ prez nt]；作为动词，其读音为[pri zent]。作为名词意为“礼物”，与gift同义，也可以表示“现在”，如本课的词组 at present。作为形容词，意为“现在的”、“ 到场的”、或“出席的”。作为动词使用，意为“授予”、“给”。如：

我打算开办一所学校，所以我在尽可能地努力节省钱。
① 注意planning双写n。
② 句中的as much money as possible也可以写成money as much as possible。因为money 是不可数名词，所以用as much as possible。如果是可数名词，常用as many as。如果强调“少”，与之对应的有as few as possible, as little as possible，同样要注意可数与不可数的区别，如：
You should spend as much time as possible in studying now.
你现在应该尽可能在学习上多花时间。
At that time I always bought as many books as possible.
那时，我总是尽可能地多买书。

尽量少说并不是上策。

(6) Unfortunately it will cost a lot of money. 遗憾的是，这要花很大一笔钱。
此句中cost是动词，意为“花费；使付出代价”。cost 是一个不规则动词，其过去式和过去分词还是 cost。cost不可用于被动语态。cost 作动词使用时主要接名词、代词作宾语，也可接双宾语结构，如：
