Do’s and Don’ts in Whale(鲸) Watching

The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel(船只) operators follow these guidelines for all kinds of whales.

· Approach whales from the side, not from the front or the back.

· Approach no closer than 100 metres, then stop the boat but keep the engine on.

· Keep noise levels down — no horns, whistles or racing of engines.

· Start your boat only after the whales are more than 100 metres from your vessel.

· Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.

· Approach and leave slowly, avoiding sudden changes in speed or direction.

· Avoid disturbing groups of resting whales.

· Keep at low speeds and remain in the same direction if traveling side by side with whales.

· When whales are traveling close to shore, avoid crowding them near the shore or coming between the whales and the shore.

· Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.

· If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.

Compulsory citywide garbage sorting began in Beijing in April, aided by new guidelines for residents and the start of a three-month inspection campaign to monitor enforcement. The strict garbage sorting rules require residents to classify their domestic trash into four different categories: kitchen waste, recyclables, hazardous waste and other waste. 1.

Communities and villages across the capital must set up four different colored trash bins. 2. To help residents better classify their domestic trash, four supporting measures would specify the management standards and implementation procedures for classifying garbage. For example, a guideline released in April advised residents to have two trash bins and one garbage bag at home to make the separation of different kinds of waste more convenient.

3. The inspection, lasting until the end of July, will focus on mixed waste and its dumping and transport. Meanwhile, the city's market supervision authorities will begin a three-month crackdown on the illegal use and sale of plastic bags.

Under the newly revised domestic waste regulation, supermarkets, shopping malls and trade markets may no longer use super thin or free plastic bags. 4.

By the end of March, there were 44 domestic waste treatment facilities in Beijing, capable of handling 32,711 metric tons of trash a day, the capital's urban management authorities said. The capital collected 10.11 million tons of household waste last year.

Some residential communities in Beijing have introduced incentives（激励）to encourage residents to sort their garbage. 5. Some communities had explored new ways of reusing kitchen waste as fertilizer for the residents' rooftop garden.

A.Law enforcement agencies will launch a three-month inspection to monitor compliance with compulsory trash sorting.

B.Those who fail to sort their garbage properly could face fines of up to 200 yuan （$28）.

C.The community acquired a trash treatment machine last year that can recycle some kitchen waste to produce organic soil in 24 hours as fertilizer for potted plants.

D.Restaurants and hotels must stop offering disposable items unless customers request them.

E.Residents can earn points by classifying their domestic waste correctly and then exchange the points they accumulate for daily necessities such as napkins and soap.

F.The treatment facility makes residents more familiar with the processing of garbage and spur their enthusiasm for trash sorting.

G.Green bins will be for kitchen waste, blue ones for recyclables, red for hazardous waste and gray for other waste.

Rivers are earthly arteries(要道) for the nutrients, deposits and freshwater that sustain healthy, diverse ecosystems. Their influence extends in multiple dimensions—not only along their length but below­ground to aquifers(蓄水层) and periodically into nearby floodplains.

They also provide vital services for people by fertilizing agricultural land and feeding key fisheries and by acting as transportation corridors. But in efforts to ease ship passage, protect communities from flooding, and draw off water for drinking and irrigation, humans have increasingly constrained and broken these crucial water ways. “We try to control rivers as much as possible,” says Gunther Grill, a hydrologist at McGill University.

In new research published in May in Nature, Grill and his colleagues analyzed the barriers to 12 million total kilometers of rivers around the world. The team developed an index(指数) that evaluates six aspects of connectivity—from physical fragmentation (by dams, for example) to flow regulation (by dams or levees) to water consumption—along a river’s various dimension. Rivers whose indexes meet a certain threshold(临界值) for being largely able to follow their natural patterns were considered free­flowing.

The researchers found that among rivers longer than 1,000 kilometers (which tend to be some of those most important to human activities), only 37 percent are not blocked along their entire lengths. Most of them are in areas with a minimal human presence, including the Amazon and Congo basins and the Arctic. On the contrary, most rivers shorter than 100 kilometers appeared to flow freely—but the data on them are less comprehensive, and some barriers might have been missed. Only 23 percent of the subset of the longest rivers that connect to the ocean are uninterrupted. For the rest, human infrastructure is starving estuaries(河口) and deltas (such as the Mississippi Delta) of key nutrients. The world's estimated 2.8 million dams are the main cause, controlling water flow and trapping deposits.

The new research could be used to better understand how proposed dams, levees and other such projects might impact river connectivity, as well as where to remove these fixtures to best restore natural flow. It could also help inform our approach to rivers as the climate changes, says Anne Jefferson, a hydrologist at Kent State University, who was not involved in the work. Existing infrastructure, she says, “has essentially been built to a past climate that we are not in anymore and are increasingly moving away from.”

1.According to the passage, which of the following is NOT a function of rivers?

A.Easing ship passage. B.Fertilizing agricultural land.

C.Transporting people or goods. D.Sustaining healthy ecosystems.

2.What does the underlined word “constrained” in Paragraph 2 most probably mean?

A.Exhausted. B.Restricted.

C.Consumed. D.Expanded.

3.The underlined word “them” in Paragraph 4 refers to “________”．

A.earthly arteries B.human activities

C.entire lengths D.unblocked rivers

4.What does Anne Jefferson mean by the underlined sentence in the last paragraph?

A.Existing infrastructure has been perfectly built.

B.Existing infrastructure doesn't depend on the past climate.

C.Existing infrastructure determines the future climate.

D.Existing infrastructure doesn’t fit the changing climate.
