题目:

我国北方某海港进港航道为5万吨级单向航道,为满足港口吞吐量发展和船舶大型化的要求,实施航道增深拓宽工程,并相应调整导助航设施,以满足10万吨级船舶单向通航和5万吨级船舶双向通航的要求。疏浚工程挖槽长10km,土质为淤泥质土,疏浚土外抛至15km远外海指定的抛泥区。承包商选用4500m3耙吸船进行挖运抛施工,有关施工参数如下:挖泥航速5km/h,重载航速20km/h,空载航速24km/h,舱载量2500m3,装舱时间0.55h,船舶调头和抛泥时间0.3h,船上装有2台泥泵,每台泥泵泥浆流量为10000m3/h,泥浆浓度为25%,时间利用率55%。该工程合同疏浚工程量1508万m3,其中设计断面工程量1224万m3,施工期回淤量很小,不计。计划工期1.5年,综合单价18元/m3。工程施工期间,业主按新的规划,要求在本工程交工后连续进行新的航道扩建工程,以满足15万吨级船舶单向通航和5万吨级船舶双向通航的要求。航道交工验收时,业主提出将本工程的超深、超宽工程量和相应疏浚工程费用列入新的航道扩建工程结算。

航道交工验收时,业主提出将本工程的超深、超宽工程量和相应疏浚工程费用列入下期工程结算的做法是否可行?说明理由。

C

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.
