　　One baobab tree in South Africa is so large that a popular pub has been established inside its trunk. Many local cultures consider baobab trees to be sacred (神圣的). Others use them for their nutritious fruits, eatable leaves and beautiful flowers.

　　But the size has not necessarily protected them. According to research published in Biological Conservation, two of Madagascar's baobab tree species will lose much of their available habitat in the next 70 years. One species may not survive to the next century. Madagascar is home to seven of the world's eight baobab species, six of which can be found nowhere else.

　　The study—by scientists from the French agricultural research center CIRAD—relied on satellite images and field work to develop population estimates and distribution models for three baobab species. All three trees are currently listed as endangered on the IUCN Red List. The study suggests that two of the species should now be reclassified as seriously endangered.

　　One of those species, A. perrieri, had the lowest current population, with just 99 trees observed during ten years of field study. The researchers estimate that climate change will decrease the habitat of this species from about 21,000 square kilometers today to just over 6,500 square kilometers in 2080.

　　The second species, A．suarezensis, had a higher estimated current population of 15,000 trees but a far smaller distribution area of just 1,200 square kilometers. Based on climate change models, the researchers estimated that the distribution of this species will cover just 17 square kilometers by 2050 and could face potential extinction by 2080.

　　The one bright spot in their study was A．grandidieri, the largest and most populous baobab species. The researchers counted an estimated one million trees with a distribution of more than 26,000 square kilometers. This isn't expected to change much by 2050.

　　As the researchers point out, there's nowhere left for the baobabs to go. Many baobab trees currently are in Protected Area Networks (PANs) established to preserve Madagascar's biodiversity, but the areas outside many PANs have been almost completely changed to agriculture or cattle feeding areas, leaving no room for the trees to expand their distribution.

　　The researchers wrote that the existing PAN system in Madagascar “is not likely to be effective for biodiversity conservation in the future” because the PANs will not always contain the ecological features necessary for the survival of the species that live inside them today. They suggest that the PAN system will need to be adapted.

　　1．According to the text, baobab trees ________.

　　A．don't bear fruits

　　B．can only be seen in Africa

　　C．are treated with respect in Madagascar

　　D．have about a dozen species

　　2．It can be inferred from CIRAN's study that ________.

　　A．it's not easy to estimate baobab trees' population

　　B．the IUCN Red List needs to be adjusted

　　C．satellite images are not totally reliable

　　D．field work plays a great role in saving baobab trees

　　3．Of the three baobab species researched by CIRAD, ______.

　　A．A.perrieri had the smallest distribution area

　　B．all of them currently are in PANs

　　C．A.grandidieri is the least endangered species

　　D．A.suarezensis is likely to disappear in 2050

　　4．What is the best title for the text?

　　A．There is an amazing big tree species in South Africa

　　B．Climate change could wipe out baobab trees in Madagascar

　　C．Expanding baobab trees' distribution is an urgent task

　　D．More efforts should be made to protect native wildlife

　　答案与解析

　　1．C　细节理解题。从第一段第二句Many local cultures consider baobab trees to be sacred (神圣的)．可知选C项。

　　2．B　推理判断题。从第三段最后一句The study suggests that two of the species should now be reclassified as seriously endangered.可知B项正确。

　　3．C　细节理解题。从第六段第一句The one bright spot in their study was A．grandidieri, the largest and most populous baobab species. 可知C项正确。

　　4．B　标题归纳题。从第二段内容可知B项正确。
