nce的例句
In the dozen years since the publication of the first edition of this book, software and interactive products have certainly improved.
的第一版问世以来，间，软件和交互产品的确有所进步。
Texture is seldom useful for conveying differences or calling attention, since it requires a lot of attention to distinguish.
很少被用来表达不同或者引起注意，由于分辨纹理需要很强的注意力。
Expanding dialog boxes were big around 一九九零 but have declined in popularity since then, largely due to the ubiquity of toolbars and tabbed dialogs.
对话框大约在一九九零年左右非常流行，自那以后主要是由于工具栏和标签对话框的无处不在而走向衰落。
It isn’t unreasonable to suspect a similar pattern in any kind of interface navigation, since this number is consistent with how much information we can hold in our short-term memories; when there are too many colors, we spend time trying to remember what the colors mean, so that slows us down.
数字同我们的短期记忆能力有关，我们的短期记忆仅仅能存储有限的信息。 因此当有太多颜色时，我们的大脑不得不花费额外的时刻记住每种颜色的意义，这样便降低了我们的处理速度。 因此，在任何界面的导航中都是这样的情况，我们毫无理由超过这个数字。
Ultimately, the use of folders or directories as a primary retrieval mechanism requires that users know where an item has been stored in order to locate it. This is unfortunate, since digital systems are capable of providing us with significantly better methods of finding information than those physically possible using mechanical systems.
作为主要检索机制的文件夹或者目录，最终需要使用者知道一个物品到底放在哪个位置，才可以找到它。 这就很不幸了，按道理讲，和各种各样的物理全球中的机械体系相比，数字全球应该有能力提供给我们更加优越的查找信息的手段，我们下面要谈的是怎样进步这种检索能力。
The document that was current at the time of the version selection will be created as a version itself. Also, since disk space is hardly a scarce resource these days, it makes sense to create versions regularly, in case it doesn’t occur to your users.
文档在这个时刻也应该成为一个新版本。 另外，既然现在磁盘空间并不是什么稀缺资源，因此有规律地生成版本是有意义的，以防使用者自己没有定时保存。
Also, we don’t want to rely on hue as the sole communication vector, since color-blindness is quite common.
由于存在着色盲现象，因此我们也不能依赖颜色，把它当做是唯一的传达矢量。
This behavior makes sense, since scrolling over long distances requires gross motor movements that make it difficult to stay within the bounds of the narrow scrollbar control.
行为很有道理，由于长距离的滚动需要粗略运动控制，使其难以保持在滚动条控件的范围内。
While multiple Undo is certainly a very useful mechanism, there’s no reason not to finish the job and use our ample computing resources to allow users to Undo just the undesirable actions, instead of everything that has happened since them.
多次撤销显然是很好的，但也没有理由放着充裕的计算机处理能力不用，而让使用者撤销并不想撤销的操作，最终还是撤销了之前全部所有操作。
. Of course, adjust these properties with restraint, since the most important element doesn’t need to be huge, red, and outdented—often, varying just one of these properties will do the trick.
，由于最重要的元素也无须同时是巨大且红色，而且还是向外突出的，因此我们要谨慎使用这些属性。 一般来说，调整其中一个属性就可以了。

She’s been working in a bank since leaving school.她中学毕业后就一直在一家银行职业。
d spoken to her only once since the party. 自从那次聚会以来，他只跟她说过一次话。

haven’t heard any noise since I slept. Sleep 为持续性动词，sleep的动作结束时，即“醒来”时，因此这句应译为“我醒后还未听到任何声音”。
若since引导的状语从句的谓语为持续性动词的现在完成时，则表示动作和情形延续到现在(说话时刻)，其表示的时刻的起点应从动作发生之时算起。例如：I haven’t heard from him since he has lived there。 这里has lived表示动作的持续性，时刻的起点应从：“开始居住”时算起。因此此句可领会为“自从他(开始)住在那儿起，我就一直没收到他的来信”。
Since在独特句型中的应用
I：“It is (has been)+时刻+since+持续性动词的过去时”，表示“自从……以来到现在已有多久。”例如：
has been quite some time since I was last in London.我上次离开伦敦至今颇有一段时刻了。

nce 的结构：(作为连词)=since 完成时态—- ever since +主+动词简单过去式
I have known him ever since he was a child. ?他从小我就认识他了。 ?这种用法同since 差不多，不过 ever since 比 since 用得少。
：We have lived in Shanghai ever since we came to China.(自从我们来到中国之后就住在上海。) ?
以上所说的 ever since 作为连词。 ?
er since 也可作为副词，解释“此后”(就一直…) ?
He fell ill at Christmas and has been ill ever since. ?他在圣诞节生病了此后就一直不适。(has + be ill)
He left home last year and has been away ever since. ?他去年离家走了，此后一直在外面。(has + be away) ?三)He fell off his horse a week ago and has been in bed ever since. ?一周前他从马背上跌下来，从那以后就一直躺在床上。 ?四)He went to Turkey in 一九五零 and has lived there ever since. ?他在一九五零年去土耳其，此后就一直住在那里。 ?
has not been able to 这实际上就是 be able to 加上 have 罢了。
be able to 就是“有可能”不是“能”(can)。如果一直，始终没有可能就是has not been able to ,这很简单。 ?如果 it has not been easy. 就是“那件事一直不是轻而易举的。”完成时态不一定都解释为“已经”，有时要解释为“一直”。 ?相关词汇：?have trouble with sb. 与某人发生了纠纷 ?return home 不可用 return to home ?at night 不可用 at the night ?because of 由于 ?even once 即使是一次 ?have effect 产生效果 ?turn … to 把···变为

nce的用法拓展资料五 第九篇
It is +时刻＋since从句的句型中，主句多用一般过去时，且since后的动词若为延续性或情形性动词，应译为否定或相反，若为短暂性动词按字面意思翻译。
：
have been in Beijing since you left.
你离开以来，我一直在北京了。
ere have you been since I last saw you?
次我和你见面以后，你到哪里去了？
efore和after引导的时刻状语从句
fore引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。还要注意主句和从句之间的时刻关系。当主句用将来时，从句总是用现在时；
before引导的主句谓语用的.是过去完成时，则从句动词多用一般过去时，这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和从句的动作的时刻关系正好与before引导的从句相反。
