1. 除非；若不；除非在…的時候
You use unless to introduce the only circumstances in which an event you are mentioning will not take place or in which a statement you are making is not true.

e.g. Unless you are trying to lose weight to please yourself, it's going to be tough to keep your motivation level high...
除非減肥是為了悅已，否則很難保持積極性。
e.g. We cannot understand disease unless we understand the person who has the disease...
若不了解患者我們就不能了解疾病。

Do not confuse unless, except, except for, and besides. Unless is used to introduce the only situation in which something will take place or be true. In the 1940s, unless she wore gloves a woman was not properly dressed... You must not give compliments unless you mean them. You cannot use unless to talk about a situation that results from something not happening. Instead you use if...not. I'll be glad if she doesn't come. You use except to introduce the only things, situations, people, or ideas that a statement does not apply to. All of his body relaxed except his right hand... Travelling was impossible, except in the cool of the morning. You use except for before something that prevents a statement from completely true. The classrooms were silent, except for the scratching of pens on paper... I had absolutely no friends except for Tom. You use besides to introduce extra things in addition to the ones you are mentioning already. Fruit will give you, besides enjoyment, a source of vitamins. However, note that if you talk about 'the only thing' or 'the only person besides' a particular person or thing, besides means the same as 'apart from'. He was the only person besides Gertrude who talked to Guy.
不要混淆 unless，except，except for 和 besides。unless用于引出某事發生或成立所必需的條件，如：In the 1940s, unless she wore gloves a woman was not properly dressed（在20世紀40年代，女性若不戴手套就算衣著不得體），You must not give compliments unless you mean them（除非出自真心，否則不要隨便恭維）。談論由于某事未發生而導致的情形不能用unless，要用 if...not，如：I'll be glad if she doesn't come（如果她不來我會很高興的）。except 用于引出陳述中唯一不適用的事物、情形、人或想法，如：All of his body relaxed except his right hand（除了右手以外，他全身都放松了），Travelling was impossible, except in the cool of the morning （除了在涼爽的早晨，其他時候出行都是不可能的）。except for用于引出使其陳述不能完全成立的事物，如：The classrooms were silent, except for the scratching of pens on paper（除了筆在紙上發出的沙沙聲，教室一片寂靜），I had absolutely no friends except for Tom（除了湯姆，我一個朋友也沒有）。besides用于引出已提到事物之外的其他事物，如：Fruit will give you, besides enjoyment, a source of vitamins（水果不但好吃，而且富含維生素）。但應注意，用于談論除某人或某物之外唯一的人或物時，besides的意思與apart from相同，如：He was the only person besides Gertrude who talked to Guy（除格特魯德之外，他是唯一跟蓋伊說話的人）。

conj.(連詞)

unless所引導的條件狀語從句常用一般現在時表示將來意義,主句多用一般將來時。unless在表示“除非”時,如其引導的從句謂語是be,而從句的主語跟主句的主語相同時,從句的主語和be就可省略。有時從句中主語為it時,也可省略it或從句中的有關成分。

在unless引導的肯定形式的條件從句中通常用肯定詞,如:already, still, some, too。在unless引導的否定形式的條件從句中通常用否定詞。

unless表示條件時后可接現在分詞短語。

conj.(連詞)

unless, if...not...

二者均可表示“如果不…”。unless不可引導虛擬語氣從句; if...not...可用于虛擬語氣結構。
