Will the fine weather keep up till tomorrow?
好天气会持续到明天吗？

注释：
1. keep up在本句中表示“保持，持续不变”，比如，“我希望好天气会持续下去”，就可以说“I hope the good weather will keep up.”
2. 除此以外，keep up还可表示“（使）不低落”，比如我们常说物价一直很高，“Prices have kept up the whole year.”如果你告诉某人要keep it up，则指要“继续努力”。
If you keep it up, you continue working or trying as hard as you have been in the past.

If we pull together, we can get this job done soon. 如果我们齐心协力，很快就可以完成这项工作。

注释：
1. pull together表示“齐心协力，通力合作”，比如度过难关。我们可以从字面上来理解这个词组，pull表示“拉，扯”，如果将一群人拉到一起，people pull together，也就是团结一致；如果是将一些想法“拉”到一起，pull together facts/ideas，则指“把……串到一起，把……连成一个整体”。
If people pull together, they help each other or work together in order to deal with a difficult situation.
If you pull together different facts or ideas, you link them to form a single theory, argument, or story.
2. 在受到很大打击或者刺激的时候，我们会说精神很崩溃，这个时候就需要将自己pull together，也就是让自己“保持镇定，振作起来”。
If you are upset or depressed and someone tells you to pull yourself together, they are telling you to control your feelings and behave calmly again.

The new material is highly resistant to steam and water.
这种新材料具有很好的耐水蒸汽性和防水性。

注释：
1. be resistant to something在本句中表示“有抵抗力的，不受……损害的”，这里主语只能为物。以句中的“防水”为例，我们可以说be resistant to water，也可以直接用water-resistant或waterproof，表示“防水的”。
其中，waterproof还可以用作名词，表示“雨衣，防水服”；或者用作动词，表示“对……进行防水处理”，常用于被动语态，如“船只经过防水处理”，“The boat has been waterproofed.”-proof这个后缀表示的就是“抗……”。
If something is resistant to a particular thing, it is not harmed by it.
2. 如果主语为人，someone is resistant to something，则表示这个人对某事很抵制、反对，比如抗拒变革，be resistant to change。
Someone who is resistant to something is opposed to it and wants to prevent it.

This trip has certainly broadened my horizons.
此次旅行确实让我大开眼界。
注释：
1. 我们一般比较了解horizon作为“地平线”的用法，而某人的“地平线”呢？  
我们可以联想一下，把这看做一个人目所能及的界限。站得越高看得越远，界限也就越宽广，someone's horizons也就是某人的“见识，眼界”。如果某事已经on the horizon了，也就是你已经能看到、预见到了，即指这件事已“初露端倪，即将发生”。我们常说的“希望的曙光”也可以用这个短语来表示，即 glimmers of hope on the horizon。
2. broaden someone's horizons即指“开阔眼界”，也可以用widen、expand来替换。我们还常用到broaden someone's mind，表示“开阔心胸”。这两个词组的区别在于，broaden someone's horizons强调增长见识、丰富经验，而broaden someone's mind强调增强某人的接受能力，让人能够更乐意接受他人的信仰和习俗。
Broaden/widen/expand somebody's horizons means to increase the range of things that someone knows about, has experienced, or is able to do.

The law will be put into effect next month.
该法案将于下个月生效。
注释：
1. put something into effect表示“实施（计划），实现（想法）”，也可以用bring和carry来替换。
If you put, bring, or carry a plan or idea into effect, you cause it to happen in practice.

2. 和这个短语很类似的还有take effect和come into effect。这几个短语都可翻作“生效”，区别在于，put/bring/carry into effect可用于被动语态；take effect和come into effect强调一种法律效力，不能用于被动语态。take effect还可指“见效，开始起作用”。
If a law or policy takes effect or comes into effect at a particular time, it officially begins to apply or be valid from that time. If it remains in effect, it still applies or is still valid.
