2．There are plenty of jobs ________ in the western part of the country.
A．present B．available

3．Everything goes smooth and the meeting is being held as ________.
A．arranged B．arranging
C．to arrange D．to be arranged
解析：选A。考查固定搭配as arranged。句意：一切进展得很顺利，会议正按安排的那样举行。as arranged是固定搭配，表示“正如所安排的那样”，符合句意。故选A。
4．The temperature continued to fall for a short time, but no ice ________.
A．forms B．formed
C．is formed D．were formed
解析：选B。考查句子的时态和语态。句中时态为过去时，所以A、C两项因为时态不一致而被排除。ice一般用作不可数名词，作主语时，谓语动词用单数形式，故D项也被排除。此时form为不及物动词，无被动语态。故选B。
