The Greek historian Herodotus is said to have made one of the earliest lists of Seven Wonders of the World.These were man-made structures，including the Hanging Gardens of Babylon.More recent times saw natural alternatives to these wonders of classical architecture proposed: waterfalls，mountains，canyons，reefs.Dramatic landscapes，features and wildlife，and the pleasure and excitement they offer to visitors，are basics of tourism.

As environmental consciousness has risen，attitudes to such sightseeing have changed.Yes，it is exciting to visit remote forests or spot rare species.But travelling to distant destinations is carbon-intensive(碳密集的) when flights or long road journeys are involved，and conservation can be made more difficult as well as assisted by sightseers.There is a balance to be struck，and some governments and businesses around the world try to increase the benefits while reducing the harm.Colombia，for example，recently introduced laws aimed at promoting sustainable tourism.Based on this，its economy got prosperous(繁荣的) as well as the tourism.

Most of us understand better than ever that there are costs as well as benefits associated with exploring.One of the commitments made by an environmental campaign launched last month，“The Jump”，is to “holiday local”，taking short flights once every 3 years and long flights very rarely.Fortunately，the UK’s 15 national parks,86 areas of outstanding natural beauty，and countless other landscapes that are without formal status，but still beloved，mean that there is no shortage of special places for domestic nature tourists to visit，while a lot of European beauty spots are accessible by rail.

One recent survey found that Windsor Great Park and Kew have become Britain’s most popular attractions.Visitor numbers at wildlife trusts are high，with waiting lists for beaver-spotting.Some companies that formerly ran foreign trips have adapted to the pandemic by taking people to watch dolphins and other marine life off British coasts instead.

As we face an environmental emergency that grows ever more dangerous，it is essential to develop appreciation for nature that surrounds us.In a small way，holiday outings to watch dragonflies，kingfishers or seals，or be surrounded by trees that are coming into leaf，could help us to focus on what matters.

1．Why are the lists of Seven Wonders mentioned?

A．To bring natural wonders into focus.

B．To show changes in architectural styles.

C．To reveal the rising popularity of tourism.

D．To compare historic and modern structures.

2．What did Colombia recently do?

A．It made efforts to conserve rare species.

B．It banned sightseers from going to remote forests.

C．It introduced laws to increase the income of tourism.

D．It tried to make its tourism develop healthily and stably.

3．What is the author’s attitude to the goal of “The Jump”？

A．Relaxed.B．Doubtful.C．Critical.D．Optimistic.

4．What can be the best title for this passage?

A．Nature Tourism：“Travel Locally”

B．Discovery of European Beauty Spots

C．International Tourism：Wait Before Setting out

D．Sightseeing Leads to Environmental Emergency

In the shallow waters near the ocean shore，kelp(海带) grows thickly absorbing CO₂ from the atmosphere.It grows at a rate of nearly 60 cm daily and if moved to a more nutrient rich depth of 80 m，it even grows faster.It’s this rapid growth that allows kelp to lock large amounts of carbon away—similar to a tree.Kelp and other species of seaweed could remove 61－268 million tonnes of carbon from the atmosphere every year.

Kelp can also be turned into biofuel.“This biofuel from kelp can use all the existing refining(精炼) systems of the petrochemical industry，” says Brian Wilcox，the chief engineer at California-based company Marine BioEnergy.“It in many cases looks like crude oil(原油) and it goes through the same processes.”

Researchers are developing what they hope could be a solution that would allow large kelp farming to be used for biofuel.Diane Kim，an ecologist at the University of Southern California，and her teammates collected two sets of kelp from their underwater habitat off the coast of Santa Catalina Island，California.Forty of the kelp chains were attached to a long line at a depth of 10 m near the kelp’s original habitat.Another 40 were fixed to a pole that could move to varying depths like a lift.For 100 days，the second set was put at a depth of 80 m during the night.During the daytime，researchers lifted it close to the ocean surface to absorb sunlight.

After the experiment，the depth-cycled kelp produced almost four times as much biomass as the set kept at the shallower depth.In addition，the depth-cycled kelp grew far faster—at 5% per day against 3.5% for the other set.Kim and her teammates believe this depth-cycling represents a promising option for biofuel generation as it allows kelp to take advantage of both the sunlight closer to the surface and the higher nutrients further down in the water column.Using methods like this could allow kelp to be farmed for biofuel.

5．In what way is kelp beneficial to the environment?

A．It lets essential nutrients flow into sea water.

B．It can take in a variety of pollutants in the ocean.

C．It is greatly helpful in reducing greenhouse gases.
