1. When a plane from London arrived at Sydney airport, workers began to unload a number of wooden boxes, which contained clothing.
当一架来自伦敦的飞机抵达悉尼机场时，工人们开始卸下来装有服装的一批木箱。
clothes和clothing均可用作“衣服”的统称，但在用法上仍有差别：
clothes：是个没有单数形式的可数名词。前面不可加不定冠词，也不可加数词，但可用some, these, those, many, few等词修饰。
正：those clothes/ few clothes/ many clothes
误：a clothes/ two clothes/ three clothes
clothing：则是一个不可数名词。比较而言：clothes的含义比较具体，而clothing的含义则比较抽象。
e.g. Our clothing protects us against the cold.
我们的衣服可以御寒。
We are well provided with food and clothing.
我们吃得好，穿得好。
若不考虑其细微区别，两者常可换用。
e.g. He spent a lot of money on clothes(clothing).
他花了许多钱买衣服。
2. No one could account for the fact that one of the boxes was extremely heavy. 其中有只箱子特别重，可谁也弄不清是怎么回事。
account for
说明；证明
e.g. He could not account for his foolish mistake.
对……负有责任
e.g. Who will have to account for the misprints in the dictionary?
关于account的词组
on account of = because of; for the sake of：由于；因为。
e.g. We got married on account of the baby.
take into account = to take into consideration; allow for：考虑；顾及
e.g. They had to take the baby into account when they wanted to go out.
on no account = under no circumstances：决不，绝对不
e.g. We must on no account miss the chance.
该句中that引导的句子是同位语从句。
同位语从句和定语从句很相似，但还是有区别的，区别主要在三方面：
1. 从性质上区别
定语从句是从句对其先行词的修饰或限制，属于形容词性从句的范畴；而同位语从句是从句对前面抽象名词的进一步的说明和解释，属于名词性从句的范畴。
2. 引导词的区别
a. 有些引导词如how, whether, what可以引导同位语从句，但不能引导定语从句，如：
That question whether we need it has not been considered. 我们是否需要它这个问题还没有考虑（同位语从句）
b. 引导词that引导定语从句时，在从句中一般作主语或宾语（指物时还可以用which代替），并且作宾语时常常省略。That引导同位语时，不充当任何成分，但不能省略，也不能用which来代替，如：
The order that we should send a few people to help the other groups was received yesterday. （同位语从句，是对order的具体解释，that虽不作成分，但不能省略）
The order that we received yesterday was that we should send a few people to help the other groups.（定语从句，是名词order的修饰语，that在从句中作received的宾语，可以省略）。
3. 先行词的区别
同位语从句前面的名词只能是idea, fact, news, hope, belief, suggestions, proposal, word, thought, doubt, truth, possibility, promise, order等有一定内涵的名词，而定语从句的先行词可以是名词、代词。
3. It suddenly occurred to one of the workers to open up the box。突然一个工人想到打开一个箱子看看。
sth. occur to sb. 表示“某人想到某事”，主语为事，宾语为人。
e.g. A good idea suddenly occurred to me.clothes和clothing
在文中it 在句中为形式主语，代替不定式to open up the box。
e.g. It suddenly occurred to me that I have left the book at home.
It occurred to me to visit my teacher.
It never occurred to me that he might be in trouble.
It didn’t occur to him that she would refuse his invitation.
  词汇辨析：take place, happen, occur, come about
1) take place 表示“发生，举行，举办”一般指非偶然性事件的“发生”。
e.g. The Olympic Games of 2008 will take place in Beijing.
2) happen 作“发生，碰巧”解，一般用于偶然或突发性事件。
e.g. What happened to you?
  I happened to see him on my way home.
= It happened that I saw him on my way home.
3) occur作“发生”解，其意义相当于happen。而此外，occur还有“想起”的意思。
e.g. What has occurred? (= What has happened?)
  It occurred to me that she didn’t know I had moved into the new house.
4) come about 表示“发生，产生”，多指事情已经发生了，但还不知道为什么，常用于疑问句和否定。
e.g. When mother woke up, she didn’t know what had come about.
    Do you know how the air accident came about?
4. After he was arrested, the man admitted hiding in the box before the plane left London. 此人被逮捕后，承认他是在飞机离开伦敦前躲进箱里的。
admit doing sth. 表示“承认做某事”。
e.g. He admitted robbing the old man.
★四级词汇辨析：admit, acknowledge, confess
1）admit通常指因外界压力、良心或判断而承认某事的存在或真实性，含有“不情愿承认”之意。
e.g. I admit that she is right.
2）acknowledge 指公开承认。
e.g. With so much evidence against him, he had to acknowledge his error.
3）confess着重承认自己的过错或罪恶，因此有“忏悔，坦白”的含义。
e.g. He has confessed his crime.
