Language points

1. They’ll be put up on the school website.

它们(照片)将被公布在学校的网站上。

put up的意思是“张贴；公布；挂起”。例如：

You can put up the notice on the noticeboard.

你可以把同志贴在布告栏上。

We’ve put up some new curtains in the living room.

我们在客厅里挂了一些新窗帘。

2. Some were huge ones with thousands of pages.

有的书甚至有几千页厚。

thousands of 后接可数名词的复数形式,表示不确定的数字，意为“成千上万的；数以千计的”，不能和数词连用。例如:

Thousands of people lost their homes in the Ya’an earthquake.

在雅安地震中，成千上万的人失去了他们的家园。

3. If you have to lend it to anyone, tell them to use it properly.

如果一定要借给其他人的话，你要告诉他们如何正确使用它。

lend作动词，意为“借给”，强调“借出”。常用短语lend sb. sth.相当于lend sth. to sb.，意为“把某物借给某人”。
