(1)
at the time ＝　一度に

These bags are very heavy, so carry one bag at a time.

（これ等の袋はとても重いから一度に一袋す”つ運べ）

(2)
at (the) best = 良くても：せいぜい**反対は　at (the) worst

I'll do my best, but I'll not be able to finish it before Thursday at best.

最善を尽くしますが、よくいっても木曜以前に終えることはできません。

(3)
at (the) least = すくなくとも

***[at（the) 最上級] 同じ形が作れる
　
「例」at the earliest「はやくとも」

　　　at the deepest 「深くても」

　　　at the latest 「遅くとも」

(4)
at present = 現在は；目下

At present freedom of speech is taken for granted.

現在は言論の自由は当然と思われている.

According to the weather forecast, the rainy season has set in Okinawa and Kyushu area.
So it comes to Kanto- area at no distant date.
The forecast also said 「we may have little rain during the rainy season this year」I wish it wouldn't have any influence on an injury to the crops.
