          1. (表示條件或假設)假如,如果,要是
          You use if in conditional sentences to introduce the circumstances in which an event or situation might happen, might be happening, or might have happened.

          e.g. She gets very upset if I exclude her from anything...
          要是有什么事情我不讓她參加,她會非常難過。
          e.g. You'll feel a lot better about yourself if you work on solutions to your upsetting situations...
          如果你設法找到解決自己麻煩的辦法,你自我感覺會好得多。

          2. (用于間接疑問句)是否
          You use if in indirect questions where the answer is either 'yes' or 'no'.

          e.g. He asked if I had left with you, and I said no...
          他問我是否和你一塊兒離開的,我說不是。
          e.g. I wonder if I might have a word with Mr Abbot?
          請問我能否和阿博特先生說幾句話?

          3. (表示與句子主要部分的陳述稍有不同)即便,縱然,雖然
          You use if to suggest that something might be slightly different from what you are stating in the main part of the sentence, for example that there might be slightly more or less of a particular quality.

          e.g. Sometimes, that standard is quite difficult, if not impossible, to achieve...
          有時即便有可能達到那個標準,那也是非常困難。
          e.g. I'm working on my fitness and I will be ready in a couple of weeks, if not sooner...
          我正在調養身體,最多兩三周以后就可以了。

          4. 如果…可以的話(通常與can,could, may 或 might 連用,在談話中禮貌地提出自己的觀點、轉換話題或打斷對方)
          You use if, usually with 'can', 'could', 'may', or 'might', at a point in a conversation when you are politely trying to make a point, change the subject, or interrupt another speaker.

          if是什么意思

          e.g. If I could just make another small point about the weightlifters in the Olympics...
          請允許我就有關奧運會舉重運動員的問題再補充一點。
          e.g. So, if we may return strictly to athletics again for a few minutes...
          因此,如果我們可以再花幾分鐘重新回到田徑運動話題上來的話……

          5. (用于句首,表示禮貌地請求某人做某事)
          You use if at or near the beginning of a clause when politely asking someone to do something.

          e.g. I wonder if you'd be kind enough to give us some information, please?
          請問您能不能給我們提供一些信息?
          e.g. If you will just sign here, we will arrange for your bank to deduct your payments automatically.
          麻煩您在這里簽一下字,我們將聯系您的銀行自動扣除您的付款。

          6. (用于引導從句中較次要的事實)即便
          You use if to introduce a subordinate clause in which you admit a fact which you regard as less important than the statement in the main clause.

          e.g. If there was any disappointment it was probably temporary...
          即便有點兒失望,也肯定是暫時的。
          e.g. Even if I'm overstating the case for nutrition, at least it will result in the woman being in charge of her own symptoms...
          即便我夸大了營養的重要性,但至少它會讓這個女人知道關注自己的癥狀。

          7. 要是不;即使不
          You use if not in front of a word or phrase to indicate that your statement does not apply to that word or phrase, but to something closely related to it that you also mention.

          e.g. A number of recent advances hold out if not the hope of a cure, then at least the possibility of some drug which could stop the spread of the virus...
          近來的一些進展即使不能提供治愈的希望,也至少有望研制出來某種藥物來阻止病毒的傳播。
          e.g. She understood his meaning, if not his words, and took his advice.
          她即便沒聽懂他的話,也明白了他的意思,并且接受了他的建議。

          8. (用于過去時,加強語氣)如果真的…
          You use if ever with past tenses when you are introducing a description of a person or thing, to emphasize how appropriate it is.

          e.g. I became a distraught, worried mother, a useless role if ever there was one...
          我變成了一個憂心如焚的母親,一個全無用處的角色。
          e.g. If ever there was the right person in the right job it was she...
          要是真的有才盡其用的人,那就是她。

          9. (與過去時連用,引出一個相對合理的理由)即使僅僅為了(或因為)…
          You use if only with past tenses to introduce what you think is a fairly good reason for doing something, although you realize it may not be a very good one.

          e.g. She writes me often, if only to scold me because I haven't written to her...
          她常來信,即使僅僅為了責怪我還沒回信給她。
          e.g. A one-to-one meeting with the US President was necessary, if only for a deeper exchange of views.
          與美國總統一對一的會談是必要的,即便僅僅是為了雙方觀點更深入的交流。

          10. 要是…多好
          You use if only to express a wish or desire, especially one that cannot be fulfilled.

          if的解釋

          e.g. If only you had told me that some time ago...
          要是你早些時候告訴我該多好啊!
          e.g. If only it were that simple!...
          要是那么簡單就好了!

          11. (表示判斷)好像,仿佛,似乎
          You use as if when you are making a judgment about something that you see or notice. Your belief or impression might be correct, or it might be wrong.

          if的翻譯

          e.g. The whole room looks as if it has been lovingly put together over the years...
          整個房間看起來好像是經過了多年的精心布置。
          e.g. His heart was pounding, as if he were frightened.
          他的心怦怦跳,似乎被嚇壞了。

          12. (表示類比)好像,仿佛,似乎
          You use as if to describe something or someone by comparing them with another thing or person.

          if是什么意思

          e.g. He points two fingers at his head, as if he were holding a gun...
          他把兩根手指指向他的頭,仿佛他正舉著一支槍。
          e.g. The two cousins looked as if they'd been carved from blocks of ice.
          兩個堂姊妹看起來像由冰塊雕刻而成。

          13. (強調某物不是真的)好像…一樣,仿佛,似乎
          You use as if to emphasize that something is not true.

          e.g. My husband, for some unknown reason, suggested that I loved my birds more than him: as if I would...
          我丈夫,莫名其妙地,暗示我愛鳥甚于愛他:仿佛我真如此似的。
          e.g. Getting my work done! My God! As if it mattered.
          把我的工作做完!老天!好像它真的很重要似的。

          14. 要說真有什么的話;甚至正相反
          You use 'if anything' to introduce something which strengthens or changes the meaning of the statement you have just made, but only in a small or unimportant way.

          e.g. Living together didn't harm our friendship. If anything it strengthened it...
          在一起住并沒有損害我們的友誼。要說真有什么的話,它反而鞏固了我們的友誼。
          e.g. Asthma drugs are not addictive and you don't need to keep increasing the dose. If anything, the reverse is true.
          哮喘藥物不會造成藥物依賴,你不用持續增大劑量。甚至正相反,減小劑量才對。

          15. 顯然不是
          You use 'It's not as if' to introduce a statement which, if it were true, might explain something puzzling, although in fact it is not true.

          e.g. I am surprised by the fuss she's making. It's not as if my personality has changed.
          她的大驚小怪令我很吃驚。顯然不是我的個性改變了。

          16. (用于給人建議)如果我是你的話
          You say 'if I were you' to someone when you are giving them advice.

          e.g. If I were you, Mrs Gretchen, I just wouldn't worry about it...
          要是我是你,格蕾琴夫人,我一點都不會擔心。
          e.g. What I'd do if I were you is be nice to him...
          如果我是你,我要做的就是對他好。

          1. 條件語句:其次,批處理文件是一種簡單的程序,可以通過條件 語句(if)和流程控制語句(goto)來控制命令運行的流程,在批處理中也可以使用循環語句(for)來循環執行一條命令.

          2. if什么意思

          2. 條件函數:掌握公式復制過程中的三種引用(相對引用、絕對引用、混合引用),條件函數(IF)和函數套用方法;了解函數在表格中的應用. 掌握自動篩選數據的設置方法(篩選狀態設置、單一以及多重條件篩選),創建多重篩選條件區的方法,

          3. if的翻譯

          7. if的翻譯

          7. if.:infielder; 內野手

          conj.(連詞)

          if作為從屬連詞,可引導條件狀語從句、讓步狀語從句和名詞從句。

          if引導條件狀語從句,從句可為真實條件從句,也可為虛擬條件從句。如為真實條件從句,謂語用陳述語氣,表示可能性很大,作“假使”“如果”解,通常用一般現在時代替一般將來時; 如果if從句中用will,表示意愿。從句如為虛擬條件從句,謂語動詞要用虛擬語氣,表示可能性不大或與過去事實相反,作“要是,假如”解。可指過去的情況,也可指現在和將來的情況。指將來情況時可用were to或should。在現代口語中,一、三人稱后常用was代替were。if引導的虛擬條件句中,助動詞were,should,had可以移至主語前,此時if可省略。

          if引導的條件從句中可以省略be和主語。

          if引導的條件從句,有時后接only以加強其語氣,表示說話人非常盼望某人提出的條件能夠實現。

          if可引導讓步狀語從句,作“雖然,即使”解,常和even連用。

          if可引導名詞性從句,作“是否”解,常放在ask, doubt, know, learn, see, wonder等動詞后。一般用在口語中,而且不能用于句首。

          if可以表示驚奇或憤怒。用于陳述語氣的否定句時,意義則是肯定的。

          If ever...在現代英語中,表示強調,用于加強主句的意思,往往含有否定意思。

          When or if〔when, or if〕表示從句所說的也許不會實現。

          if any的意思是“如果有的話”。

          if only可表示對現時或未來的愿望,也可表示與過去事實相反的愿望,作“只要…但愿,要是…就好了”解。

          What will happen if...?意思是“要是…怎么辦”。常縮略成What if...?

          If not后可加動詞,通常動詞省略,可用于現在時態或現在完成時態,表示“要不,不然”; 也可用于yes〔no〕疑問句之后,表示“許諾,告誡”。

          conj.(連詞)

          if, in case

          這兩個詞(組)的共同意思是“以防萬一”。二者均可引導條件從句,其區別是:

          if可用于任何時間,而in case只指將來時間。例如:

          I am taking an umbrella in case it rains later on.

          我帶著一把傘,以防一會兒下雨。

          I'll take an umbrella if it rains later on.

          要是一會兒下雨,我就拿把傘。

          conj.(連詞)我想知道她是否發現了什么。

          I wonder if she found something.

          I wonder if she found anything.

          if引導的從句中,通常用any, anything, anybody, anywhere作從句的賓語,而不用some, something, somebody, somewhere。

          ☆ 直接源自古英語的gif,意為如果,假設。
