Dolphin or not a dolphin? That is the questio...

Dolphin or not a dolphin? That is the question! You see，there are several types of dolphins．Some are saltwater dolphins while others are river dolphins．

“What are the 32 types of dolphins?”When people are asking the question，they are actually referring to the saltwater dolphins in oceans and seas．The river dolphins living in fresh water are not included in these species．But what would be the answer in this case if we ask．“Dolphin or not a dolphin?”The answer would obviously be yes．River dolphins still belong to the dolphin family．

Among the 32 types of dolphins do not actually wear the word“dolphin”in their names，such as the tucuxi，while others actually have the word“whale”as part of their names even if they are not whales but in fact，belong to the dolphin family，for example，the melon-headed whale and the killer whale．So what would be the answer to the question“Dolphin or not a dolphin?”in these cases? It would’be yes．All these species do belong to the dolphin family．

Another question that people ask is．“Are the sea animals that perform at aquariums(水族馆)all dolphins?”So，it always seems to come back to the question，“Dolphin or not a dolphin?”Well the answer is no in this case．The sea animals that perform there are not all dolphins．The beluga which people tend to think belong to the dolphin family because they show what seems like a smile，like most dolphins，are in fact a species of the whale family．

Now that you read these facts about dolphins，you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family but in either case，it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin．That is the question ！

1.Which of the following statements about dolphins is RIGHT according to the passage?

A. The tucuxi is a type of dolphin living in rivers．

B. There are 32 types of dolphins in the world altogether．

C. All the sea animals that perfom at aquariums are dolphins．

2.What do we know about the majority of the dolphins?

To switch or not to switch, that is the question．Google’s announcement of its Nexus One smartphone（智能手机） happened over a week ago and I’m still receiving lots of e-mails from readers asking the same question: Should they give up their iPhone for the Nexus One?

Some people with iPhones, disappointed by American Telephone&Telegraph’s inadequate service and the high monthly cost, are wondering if they have really got something to replace it．Does the Nexus One offer the functions that Apple has led them to expect?

I’m on the fence myself, even though I never thought I’d be interested in anything but the iPhone．From my experience using the Nexus One, and from talking to people who have made the change, it’s not necessarily about the differences between the iPhone and the Nexus One．The phones are extremely similar in design and general feel．Instead, the decision can be made based on the software（软件） services you use on your desktop．

My friend Chad Dickerson received a pre-launch Nexus One from Google three weeks ago．He said Google’s phone feels connected to certain services on the Web in a way the iPhone doesn’t．“Compared to the iPhone, the Google phone feels like it’s part of the Internet to me,” he said．“If you live in a Google world, you have that world in your pocket in a way that’s cleaner and more connected than the iPhone．”

Personally, the phones work perfectly with their own software, but both of them don’t make an effort to play well with other services．

1.Why are some iPhone users expecting a new type of phone?

2.What’s the author’s attitude towards the new phones in the third paragraph?

3.In Chad Dickerson’s opinion, the Nexus One is ________ the iPhone．

4.The best title of the passage might be ________．

To pollute or not to pollute? That is the question. In order to survive, we all need to cause pollution. Factories that process the food we eat, clothes we wear, and cars we drive have to cause pollution. The environment has the ability to absorb our waste or the pollution, but its absorption ability has its limits. If the pollution level is higher than what the environment can cope with, then that's the time when pollution is bad.

If the pollution level becomes too high, human health can be affected badly. Then, the productivity level of the sick people is low and the economy suffers. The economy suffers not only because of the lost productivity of the people, but also because the government must pay for the damage the pollution has done to its people.

This is the reason why the government prefers taxation policy. Imposing（征收）a tax on firms that pollute the environment can be considered a good strategy, as long as the tax covers all the external costs or the cost of the damage the firm has created during production.

Taxation, if enforced（执行）really well, can make firms create a technology that may reduce pollution, if they find out that it will be cheaper than continuously paying the tax. The disadvantage of this policy, however, lies in the possibility that some big firms will find the tax cheap and then they will just produce more and pollute the environment more. If other small firms find the tax expensive, thus closing down, their production will be eaten up by those firms which can afford the tax.

Therefore, it is important that lawmakers in each country, when deciding to impose a tax on pollutant emissions, first review and analyze very carefully the real cost of the damage.

1. We can infer from the first paragraph that

A. for human beings pollution is unavoidable

B. it's not easy to figure out how bad pollution is

C. humans should reduce the use of everyday products

D. we can survive without causing pollution.

2.The underlined word "absorb" here refers to”____”．

A. reduce　　 B. fit in

C. avoid　　 D. deal with

3.What is the second paragraph mainly about?

A. The effects of pollution on human health.

B. The relationship between people and their government.

C. The effects of pollution on economic development.

D. The relationship between human health and economic development.

4.Which of the following can be the result of imposing a higher tax according to Paragraph 3 ？

A. Firms may reduce the prices of their products.

B. Firms may develop some environmental technology.

C.A big firm will be broken up into small firms.

D.A small firm will try to pass the tax on to consumers.

All Ric O Barry wants is to stop the dolphin­killing, so he is headed to this seaside Japanese town, Taiji.The American activist, who is the star of a new award­winning documentary that portrays the dolphin­killing here, got an unwelcome reception when he showed up here this week for the start of the annual hunt.

His movie, The Cove(海豚湾), directed by National Geographic photographer Louie Psihoyos, was released in the United States a month ago but has not yet to come out in Japan.

Scenes in the film, some of which were shot secretly, show fishermen banging on metal poles stuck in the water to create a wall of sound that scares the dolphins— which have supersensitive sonar(声纳系统)—and sends them fleeing into a cove.

There, the fishermen sometimes pick a few to be sold for aquarium shows, for as much as $150,000. They kill the others, spearing(刺) the animals repeatedly until the water turns red. The meat from one dolphin is worth about 50,000 yen, and is sold at supermarkets across Japan.

Greenpeace and other groups have tried to stop the hunt for years.Activists hope The Cove will bring the issue to more people internationally—and eventually in Japan.

Already，the Australian town of Broome dropped its 28­year sister­city relationship with Taiji last month，partly because of the movie.

“Some regions have a tradition of eating dolphin meat，” said fisheries official Toshinori Uoya. “Dolphin­killing may be negative for our international image, but it is not something orders can stop.”

The town government in Taiji—which has made whales and dolphins its trademark—refused to comment about The Cove, or the growing international criticism against dolphin­killing.

Many in Taiji take the dolphin hunt for granted as part of everyday life. They are defensive about The Cove，seeing themselves as powerless victims of overseas pressure to end a simple and honest way of making a living.

1.Ric O Barry made The Cove because he wanted to ________.

A．stop the dolphin­killing

B．win an international award

C．support Greenpeace's efforts

D．make Taiji well­known in the world

2.Viewers can learn from The Cove ________.

A．the advanced techniques to catch dolphins

B．the cruel and bloody dolphin­killing

C．the beautiful Japanese seaside town Taiji

D．the sale of dolphin meat around the world

3.What is the response to The Cove on the Japanese side?

A．Taiji broke up with its western sister­city Broome.

B．Japanese officials decided to ban dolphin­killing.

C．The town government in Taiji kept silent on criticism.

D．Most Japanese people were against eating dolphin meat.

4.What does the underlined word “defensive” probably mean?

A．Feeling guilty for killing dolphins.

B．Protecting themselves against criticism.

C．Attacking those against dolphin­killing.

D．Making the determination to change.

5.What can we infer from the passage?

A．Many people in Japan have seen The Cove in the cinema.

B．The Cove has not influenced Japan's international image.

C．Taiji's dolphin­killing industry has been seriously damaged.

D．The Cove has brought international attention to dolphin­killing.
