_____ you buy the tickets in advance,you won't be able to see that concert.

A.Unless B.Before
选A
unless= if ...not.
原句可以重写为：
if you do not buy the ticket in advance,you won't be able to see that conert.
The manager,____ his factory's products were poor in quality,decided to give his workers further training.
A.konwing B.known
那位经理知道他工厂的产品质量很差,决定让他的员工进行培训.
知道,主动的,他自己知道,所以用A
基本上,Konw要用被动语态is known as/for ,表示因为……而出名,不做“被知道”的意思.
British writer Doris Lessing, ____87,says the prize.
A.ageing B.aged
英国作家 Doris Lessing,87岁,说.
选B
已经有动词says说,所以要用非谓语的动词.
ageing 成熟, 变老
并且,aged+数字,算是固定用法了.表示几岁几岁.
In fact,many of our guests ask for accommodationgs here___ they come
A.for the first time B.each time
关于这题,我知道the first time 是用来连接两句句子的,那选项没这个,那为什么选A?
选A
实际上,许多客人第一次来的时候,都会询问膳宿问题.
先不看答案,按照常理来推,也是第一次才会问.
A表示,第一次,首次,初次,
i came here for the first time.
我第一来这里.
B表示每一次.
我的建议是,你别用什么链接句子啥啥的来看,这样很复杂化,你直接按中国人来学,翻译成汉语,中文意思,对照一下,就一目了然了.
