      Today, we have a world economy. Canadian businesses and workers must compete with businesses

and workers in other countries.

      Every year, more Canadian factories are closing or moving. They cannot compete with factories in

countries where wages (工资) are low. In the future, there will be fewer jobs for factory workers in

Canada.

      Many Canadian businesses are trying to spend less money. For example, they are hiring more part-time

workers and more temporary (临时的) workers. They are employing fewer permanent (永久的) full-time

workers. More services, fewer goods. Canada's economy is changing. Businesses are making fewer goods

(for example: shoes and radios). But Canadian businesses are providing more services to people. 

      In the future, there will be more jobs for people who provide services. For example: sales people, waiters

and waitresses, home health care workers, bakers and cooks.

      There will be fewer jobs for other kinds of workers (for example: farmers, miners, fishermen, forestry

workers and factory workers). Many new jobs will be in small businesses with 20 or 30 employees.

Technology machines are changing the way people work.

      Business are using many machines (for example: computers and robots). Businesses will need fewer

workers. And some jobs will disappear. Many grown-ups will have to go back to school or train for new

jobs. Workers will not stay in the same job for their lifetime. The population of Canada is changing.

      Today, many Canadians are in their 30s and 40s. They need goods and services. As they get older, they

will need different goods and services.

      Canadians come from many cultures. They have different customs and religions. Employers and workers

must learn to work with many different people.

某监理单位承担了一工业项目的施工监理工作。经过招标，建设单位选择了甲、乙施工单位分别承担A、B标段工程的施工，并按照《建设工程施工合同(示范文本)》分别和甲、乙施工单位签订了施工合同。建设单位与乙施工单位在合同中约定，B标段所需的部分设备由建设单位负责采购。乙施工单位按照正常的程序将B标段的安装工程分包给丙施工单位。在施工过程中，发生了如下事件。
事件1：建设单位在采购B标段的锅炉设备时，设备生产厂商提出由自己的施工队伍进行安装更能保证质量，建设单位便与设备生产厂商签订了供货和安装合同并通知了监理单位和乙施工单位。
事件2：总监理工程师根据现场反馈信息及质量记录分析，对A标段某部位隐蔽工程的质量有怀疑，随即指令甲施工单位暂停施工，并要求剥离检验。甲施工单位称：该部位隐蔽工程已经由专业监理工程师验收，若剥离检验，监理单位需赔偿由此造成的损失并相应延长工期。
事件3：专业监理工程师对B标段进场的配电设备实行检验时，发现由建设单位采购的某设备不合格，建设单位对该设备实行了更换，从而导致丙施工单位停工。因此，丙施工单位致函监理单位，要求补偿其被迫停工所遭受的损失并延长工期。
