Plant Exploration in the 18th and 19th Centuries
Collecting“exotic”plants dates 1 to the earliest times.The first plant collecting expedition 2 in history was around 1500 BC when the Queen of 3 sent ships away to gather plants,animals and other goods.
It was not until the 18th and 19th centuries 4 the exploration of the botanical world began on a large 5 .
An important group of collectors were French 6 missionaries.Father d’Incarville once sent some Tree of Heaven seeds to 7 .
Sir Joseph Banks was a very famous British plant collector,who 8 James Cook on his first voyage from England to Oceania.The purpose of the trip for Banks was to record the plant and animal life they 9 .
At that time,keeping plants 10 during long land or sea voyages was an enormous challenge.
The world of plant exploration was completely changed with Dr Nathaniel Ward’s invention of a 11 sealed portable glass 12 .This invention,called the Wardian case,allowed plants to be 13 on long journeys.
Robert Fortune was one of the earliest plant collectors to use Wardian cases.In order to travel 14 in China,he developed his 15 in Chinese and dressed as a Chinese man,even 16 his head in the Chinese style.
During the second half of the nineteenth century many Catholic missionaries were sent to China from 17 .Father Farges collected 37 seeds from a tree that had 18 to him.This tree was later called the Dove Tree.
In 1899,E H Wilson was able to collect a large quantity of seeds of the Dove Tree that Father Farges had discovered.

六、阅读理解
A
If you travel to a new exhibit at the San Francisco Conservatory of Flowers,you will have chances to see some meat-eating plants.Take bladderworts,a kind of such plant,for example.They appear so small and grow in a quiet pond.But these are the fastest-known killers of the plant kingdom,able to capture a small insect in 1/50 of a second using a trap door!
Once the trap door closes on the victim,the enzymes(酶)similar to those in the human stomach slowly digest the insect.When dinner is over,the plant opens the trap door and is ready to trap again.
Meat-eating plants grow mostly in wet areas with soil that doesn’t offer much food value.In such conditions,these amazing plants have developed insect traps to get their nutritional needs over thousands of years.North America has more such plants than any other continent.
Generally speaking,the traps may have attractive appearance to fool the eye,like pitcher plants,which get their name because they look like beautiful pitchers(a container like a bottle)full of nectar(花蜜).
The Asian pitcher plant,for example,has bright colours and an attractive half-closed lid.Curious insects are tempted to come close and take a sip,and then slide down the slippery(光滑的)slope to their deaths.
Hair-like growths along the pitcher walls ensure that nothing can escape,and the digestive enzymes can get to work.A tiny insect can be digested in a few hours,but a fly takes a couple of days.
Some of these pitchers are large enough to hold two gallons.Meat-eating plants only eat people in science fiction movies,but sometimes a bird or other small animals will discover that a pitcher plant isn’t a good place to get a drink.
1.From the first paragraph,we can know that bladderworts can .
A.capture 50 small insects in a second
B.capture an insect in the shortest time
C.be found floating on a quiet lake
D.digest an insect in 1/50 of a second
答案:B
解析:细节理解题。第一段指出,bladderworts能在1/50秒的时间内捕获一只小昆虫,是植物中已知的捕获动物速度最快的,因此选B项。
2.If the trap door of a meat-eating plant is closed,the plant .
A.is fooling insects into taking a sip
B.is producing nectar
C.is tempting insects to come close
D.is enjoying a dinner
答案:D
解析:细节理解题。第二段说,一旦“陷阱门”将猎物关起来,类似于人胃里的那些消化酶就开始慢慢地消化它了,由此判断D项正确。
3.Meat-eating plants can grow in wet and poor soil because they .
A.can get nutrition from animals
B.don’t need much food value
C.can make the most of such conditions
D.have developed digestive enzymes
答案:A
解析:推理判断题。这些植物生长在潮湿贫瘠的土壤中,为获得生长所需的养分,在数千年的进化中,它们演化出了捕获昆虫的“陷阱”,由此推出它们主要从动物身上获取养分,而不是从土壤中获取养分。
4.Which of the following is the picture of the Asian pitcher plant
答案:A
解析:推理判断题。根据第四、五段可知亚洲捕虫草主要有这些特征:状如水瓶,颜色鲜亮,有半掩的盖子,综合此三项可知,只有A项最合适。
B
(2014辽宁,C)
Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation
UBC Professor Simard explains how trees are much more complex than most of us ever imagined.Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was.In fact,the opposite is true:trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy.This hidden system works in a very similar way to the networks of neurons (神经元)in our brains,and when one tree is destroyed,it affects all.
Simard talks about “mother trees”,usually the largest and oldest plants on which all other trees depend.She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow.When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.
“We didn’t take any notice of it,” Simard says sadly.“Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.
5.The underlined sentence “the opposite is true” in Paragraph 2 probably means that trees .
A.compete for survival
B.protect their own wealth
C.depend on each other
D.provide support for dying trees
答案:C
解析:句意理解题。根据画线句子后的内容“trees survive through their co-operation and support,passing around necessary nutrition ‘depending on who needs it’”可知答案为C项。
6.“Mother trees” are extremely important because they .
A.look the largest in size in the forest
B.pass on nutrition to young trees
C.seem more likely to be cut down by humans
D.know more about the complex “tree societies”
答案:B
解析:细节理解题。根据第四段第一、二句可知。
7.The underlined word “it” in the last paragraph refers to .
A.how “tree societies” work
B.how trees grow old
C.how forestry industry develops
D.how young trees survive
答案:A
解析:推理判断题。代词it通常用来指代上文的内容,根据第四段最后一句“When humans cut down ‘mother trees’ with no awareness of these highly complex ‘tree societies’ or the networks on which they feed, we are reducing the chances of survival for the entire forest.”可知答案。
8.What would be the best title for the passage
A.Old Trees Communicate Like Humans
B.Young Trees Are In Need Of Protection
C.Trees Are More Awesome Than You Think
D.Trees Contribute To Our Society
答案:C
解析:主旨大意题。本文属于科普知识介绍,但作者用寓言故事般的叙述方式告诉我们树木是神奇的,它们有自己的社会,有自己的生存法则,比我们想象的更令人敬畏。
