Ⅳ.阅读理解

Birds in eastern North America are picking up the pace along their yearly migratory(迁移的) paths.The reason,according to researchers,is rising temperatures due to climate change.

Using migration information collected in eBird,a citizen science program database containing 10 years’ worth of observations from amateur birdwatchers,assistant professor of biology Allen Hurlbert,Ph.D.,and his team analysed when 18 different species of birds arrived at various points across their migration journeys.

Pushing migration earlier in the year could negatively affect birds over the long term,Hurlbert said.“Timing of bird migration is something critical for the overall health of bird species,” he said.“They have to time it right so they can balance arriving on breeding(繁殖) grounds after there’s no longer a risk of severe winter conditions.If they get it wrong,they may die or may not produce as many young.”

Hurlbert said,the speed at which a species migrates is the biggest influence on how strongly it responds to increasing temperatures.Slow migrators were the most adaptable to changes.Additionally,the length of the migration path affects how quickly birds move from one location to another.

“It makes sense that if you take your time to move north,you’re sort of checking out the surroundings around you,” he said.“If the conditions seem too cold,you can decide there’s no point in moving on that day.Species that tended to advance quickly,as well as those migrating from greater distances,such as Central or South America,were less able to adapt to temperature changes.”

However,being a slow traveller does not free a species from all climate change-induced migration challenges.Because they stay in one spot longer,such birds have heavier habitat and food requirements,making them more dependent upon the resources that are available along their paths.That reliance could become a greater problem if climate projections for the next 50 years to 75 years hold true,Hurlbert said.Climatologists predict the Northeast will continue to warm at a faster pace than the Southeast,potentially forcing slow migrators to move even slower and put greater difficulty on their migratory routes.

【语篇解读】这是一篇议论文。文章主要讲述了科研人员对北美洲东部的鸟类的迁徙进行了研究,研究人员发现,鸟类迁徙速度加快的原因是气候变化导致气温上升。从数据库的分析来看,鸟类迁徙的时机对鸟类的整体健康至关重要,此外研究人员还对影响鸟类迁徙速度的因素进行了探究。

1.The rising temperatures led to 　　　. 

A.the speed-up of birds’ migration

2.According to Hurlbert,wrong timing of bird migration can lead to 　　　.

B.change in life habits

C.a lack of natural resources

D.decrease in bird population

答案D

解析细节理解题。根据文章第三段中“ If they get it wrong,they may die or may not produce as many young.”可知,赫尔伯特说不正确的鸟类迁徙时间会导致鸟的数量减少。结合选项,故选D项。

3.What is the most important factor in adapting to climate change for birds?

Ⅵ.读后续写

A young man had bought an old house that was in bad shape,but he and his wife believed they could restore it.They immediately went to work.Their goal was to have the old building look best for the Christmas Eve get-together.

Just two days before Christmas,however,a storm swept through the area,leaving a hole in the wall of the house.There was obviously no time to repair the damage before Christmas.The sad couple attended local auction (拍卖) that afternoon.One of the items put up for bids (竞标) was an old gold-and-ivory-coloured tablecloth.Seized by an inspiration,the young man was the highest bidder at $6.50.His idea was to hang the cloth to cover the ragged hole.

On the day before Christmas,it was snowy.As the young man unlocked the house door,he noticed an old woman standing at the bus stop.He knew the bus wouldn’t be there within at least half an hour,so he invited her inside to keep warm.

When the woman walked in and saw the tablecloth,she rushed at it and said excitedly,“It’s mine.It is my tablecloth.” She told the surprised man its history and even showed him her name in one corner of the tablecloth.She and her husband had once lived in Vienna,Austria,and their village was hit by a deadly disease.So they decided to flee to Switzerland,but her husband told her to leave first,saying he had something urgent to deal with.A few days later,it was reported that the bus her husband took fell off the cliff and he was never to be found.Her husband was believed to have died.Touched by her story,the young man asked about her address,planning to send the tablecloth to her after Christmas.As the bus came,she left.

When the Christmas Eve came,the man invited his friends to come to his house to enjoy the dinner together.In the candlelight of the Christmas Eve,the tablecloth looked even more beautiful.As the man’s friends left the house,they thanked the man for his arrangement and mentioned how beautiful the house looked.

Paragraph 1:

One old gentleman stayed,admiring the tablecloth. 

Paragraph 2:

The young man drove the old man to that old woman’s home.

Paragraph 1:

One old gentleman stayed,admiring the tablecloth.He said to the young man,“It’s strange.Many years ago my wife used such a tablecloth only on very special occasions.But we lived in Vienna then.Where did you get this one?” sighed the old man,tears streaming down his cheeks.The young man told him what happened that day when he met an old lady.With the trembling old man at his side,he telephoned the family and decided to visit the old woman.

Paragraph 2:

The young man drove the old man to that old woman’s home.Together they knocked on her apartment door.When she opened it,the young man witnessed the tearful,joyful and thrilling reunion of husband and wife.If the chain of events had been broken,the husband and wife might never have found each other.It was the tablecloth that made an extremely lucky ending.Love is like a journey,starting at forever and ending at never.
