每當(dāng)做試驗(yàn)時(shí)，他總是對(duì)所獲得的結(jié)果檢查兩遍。

* A magnetic needle will point toward the magnetic north pole.

磁針總是指向磁北扱。

3. 表示許可、可能性

這種用法相當(dāng)于情態(tài)動(dòng)詞can，可譯為“可以”、“會(huì)”、“能”等。如：

* If you are developing a video for the web you will use a popular compression format with high compression and a low resolution.

如果你在制作網(wǎng)上視頻材料，可以使用低分辨率和高壓縮率的常用壓縮格式。 

* These electrons will not pass into the phototube because of the insulation on the metal plate.

由于金屬板上有絕緣層，這些電子不能進(jìn)入光電管。

* This will result in the fatigue fracture of the piston rod.

這樣活塞桿就會(huì)產(chǎn)生疲勞斷裂。

4. 表示虛擬、條件、假設(shè)

可譯為“要”、“將要”、“會(huì)”、“就會(huì)”等，或靈活翻譯。如：

* If a laser beam were not so intense, it would not be able to melt metals.

如果激光束不那么強(qiáng)烈，它就不能熔化金屬。

* Without gravity there would be no air and no sound of any kind.

如果沒有重力，就不會(huì)有空氣和任何聲音。
