Vancouver(温哥华)

Natural Resources

As a major centre for the global forestry industry, Vancouver is host to many international forestry conferences and events, and the natural home of the massive BC forestry business. Companies such as Canfor and West Fraser Timber Co., the second and third largest lumber（木材）producers in the world, are headquartered in Vancouver. Vancouver is also a major centre for the mining industry.

International trade

International trade is a key part for Vancouver's economy. The city has Canada's largest port and is one of North America's major gateways for Pan-Pacific（泛太平洋）trade. The Port of Vancouver ranks first in North America in total foreign exports and second on the West Coast in total goods volume.

Banking and Financial

The headquarters for HSBC Canada （汇丰银行）is located in the Financial District in downtown. Canada's third largest commercial entity(实体), Jim Pattison Group is also based in Vancouver.

International relation

Vancouver is a major centre for diplomacy(外交) and foreign relations. Most countries of the world have consulate（领事馆）or general offices in the Central Business District. In fact, many major diplomatic conferences are hosted by the city - including the world famous G7 summit with President Clinton, APEC, and the World Trade Organization. Greenpeace has its world headquarters in the city. Therefore, Vancouver was among the first North American cities to declare itself a Nuclear Weapons Free Zone.

Tourism

Tourism is a leading industry to Vancouver. The Whistler-Blackcomb Resort is among the most popular skiing resorts in North America, and will be the site of the downhill events of the 2010 Winter Olympics. Vancouver's beaches, parks, waterfronts, and mountain backdrops and its multi- cultural character attract more and more tourists.

Film

Vancouver was the source of the sobriquet（绰号）"Hollywood North", for hosting the production of about ten percent of Hollywood's movies. Many U.S. television and films series are shot exclusively in Vancouver. This has partly been because of the favourable Canadian dollar exchange rate.

What time is it? Most people are pretty accurate in their answer. And if you don’t know for sure, it’s a very likely that you can find out. There may be a watch on your wrist, there may be a clock on the wall, desk, or computer screen; or maybe you’re riding in a car that has a clock in the dashboard (仪表板).

Even if you don’t have a timepiece of some sort nearby, your body keeps its own beat. Humans have an internal clock that regulates (调节) the beating of our heart, the pace of our breathing, the discharge (排出) of chemicals within our bloodstream, and many other bodily functions.

Time is something from which we can’t escape. Even if we ignore it, it’s still going by, ticking away, second by second, minute by minute, hour by hour. So the main issue in using your time well is, “Who’s in charge?” We can allow time to slip by and let it be our enemy. Or we can take control of it and make it our ally.

By taking control of how you spend your time, you’ll increase your chances of becoming a more successful student. Perhaps more importantly, the better you are at managing the time you devote to your studies, the more time you’ll have to spend on your outside interests.

The aim of time management is not to schedule every moment so we become slaves of a timetable that governs every waking moment of the day. Instead, the aim is to make informed choices as to how we use our time. Rather than letting the day go by, largely without our awareness, what we are going to discuss next can make us better able to control time for our own purposes.

The underlined word “ally” in Para. 3 more likely means somebody or something that is _________.

A. your slave and serves you B. your supporter and helps you

C. under your control and obeys you D. under your influence and follows you

The author intends to tell us that time _____________.

A. could be regulated by a timepiece such as a clock or a watch

B. could be managed by the internal clock of human bodies

C. should be well managed for our own interest

D. should be saved for outside interests

In the next part, the author would most probably discuss with you ________.

A. how to keep up with the times B. how to make up for lost time

C. how to have a good time D. how to make good use of time

Brand is often regarded as the creation of western advertisement industry. However, the earliest “brand” could be traced back to the early civilization in China and Egypt. Earthenware(陶器)made in China thousands of years ago had signs or symbols of pottery makers, and domestic animals branded with marks could also be seen on wall paintings of ancient Egypt. These might be the first “brand” in history.

Time passes and the situation has changed. Nowadays Americans have “Cadillac”, Japanese have “Toyota”, Cermans have “Mercedes-Benz”, and they are all proud of the big brands they own. Chinese national brands are pale in comparison to their global counterparts. It is a reality which we cannot deny and have to face. With the globalization of brands and the internationalization of global competition, foreign brands are making constant efforts in attacking the Chinese market. Under the circumstances, the question that we must ask is：How can Chinese brands be ready for the challenge posed by foreign brands?

Many Chinese enterprises are single-minded in getting the attention of the international market and going into metropolises(大城市). Successful though they seem, they act ill-advisedly. We should be aware that it is the home market, especially the rural market with a population of 900 million people that provides the real development opportunity for Chinese national brands. That is why many powerful foreign brands are trying, with every possible means, to develop the Chinese rural market.

Quality is the life of a brand and consumers always choose products with first-class quality. The quality of Chinese products is very unstable so that it seriously affects the establishment of Chinese brands. Therefore, for those national brands determined to challenge foreign brands, the top task is to improve product quality. It must be clearly understood that, for a consumer who has bought a product, defects in 1% of your products mean 100% loss. Only if we create products with quality better than that of foreign brands can national brands be successful in competition.

What is the question that we have to ask in face of foreign brands?

A．How to run a company in foreign countries.

B．How to stay in harmony with the foreign brands.

C．How to catch up with the foreign company in service and price.

D．How to compete against the foreign brands.

Which of the following would the author agree with?

A．Quality is the most important element for a brand.

B．China’s international market is fully feveloped.

C．China’s products are matchless in the international market.

D．China’s goods are always of bad quality.

Which of the following is NOT true according to the passage?

A．Metropolitan areas are what many Chinese enterprises focus on.

B．Pottery made in ancient China had signs or symbols of the makers.

C．The top target of foreign enterprises in China has been the rural market.

D．Chinese enterprises should try to get into the home market.

What can be concluded from the passage?

A．There’s no need for foreign brands to make constant efforts to compete with Chinese brands.

B．Ancient Chinese and Egyptians knew how to mark or symbolize their works.

C．Chinese enterprises can hardly build big brands people trust due to quality problems.

D．Chinese brands can only be successful in domestic market.
