  一、 考试概述:

  今天的考试第一篇和第三篇都不算难,虽然第一篇的话题很新,但文章并没有涉及太多生僻的方面,只是老生常谈的讲了开垦荒地,种植农业等内容,而且题型比较友好,最适合先做。但是第二篇出现了很多专业词汇,影响烤鸭们的阅读速度和答题,另外这篇文章的题型也稍难,会影响考生的心情,建议先做第三篇。

  二、具体题目分析

  Passage 1:

  题目:The Baobabs of Madagasgar 猴面包树

  题型:6判断题+7填空题

  题号:旧题

  文章大意: 第一部分:背景。面包树的生长区域、生长周期、品种以及Avene des Baobads 是最佳的观赏地区。

  第二部分:这种树具备的宗教和精神记忆。

  第三部分:具体说明Avene des Baobads这个地区的环境,其实是man-made的,因为当地的clearance以及burning等行为

  第四部分:面临一定的风险及其原因,比如water、cyclone;在森林地区面临风险有三个原因:farming、logging和animals。

  第五部分:Jim Bondie用两种方式把这一物种记录下来:编制远航图,或用儿童书籍记录

  参考答案:

  1-6) 判断题

  1. FALSE。All Baobabs can be found here.在原文第一段一共8个品种,其中6个在Baobabs,所以题目是对原文信息的否定。

  2. FALSE。Can be found in most areas.但是原文提到:只是集中在个别地区。

  3. NOT GIVEN。A and Grandielir is the first botanist to study… 原文说树的名字是以19世纪的这两研究人员命名的。

  4. TRUE。Avene des Baobads主要是通过农业形成的,因为原文指出:man-made, farming and clearance 等人类行为,所以是同意替换。

  5. TRUE。Baobads provide valuable products to the local people. 原文能够找到同意说明。

  6. 待补充。

  7-13) 填空题

  Marondava area:

  7. water

  8. cyclones。

  Forest area某专家发明了装置可以利用:

  9. farming

  (答案仅供参考)

  参考文章:

  Grandidier's baobabs have massive, cylindrical, long, thick, trunks, up to three meters across, covered with smooth, reddish-grey bark. They can reach 25 to 30 m (82 to 98 ft) in height. At certain times of the year the flat-topped crowns bear bluish-green palmate leaves, dark brown floral buds or spectacular flowers with white petals. The large, dry fruits of the baobab contain kidney-shaped seeds within an edible pulp.

  The long-lived Grandidier's baobab is in leaf from October to May, and flowers between May and August. The flowers, said to smell of sour watermelon, open just before or soon after dusk, and all the pollen is released during the first night. The tree is pollinated by nocturnal mammals, such as fork-marked lemurs and insects like the Hawk Moth. The lemurs move through the canopies, inserting their snouts into the white flowers and licking nectar from the petal bases, resulting in pollen being deposited in the lemurs' faces, whereas the moth is slightly more effective at pollination because it is able to fly from tree to tree with most of its body covered in pollen.

  The species bears ripe fruit in November and December. Unlike the baobabs of Africa and Australia, it appears that the seeds of the tasty fruit are not dispersed by animals. Lemurs are the only living animals on Madagascar that are capable of acting as seed dispersers, yet seed dispersal by lemurs has never been documented. In the past, however, this could have been very different. There are several species that have gone extinct since human colonization of the island (1,500 to 2,000 years ago) that could very likely have been dispersers of the seeds. This includes species of primates that were thought to be similar to baboons, and the heaviest bird that ever lived, the elephant bird, which had a powerful beak that could have opened large fruit. Today, water may be the means by which the seeds are dispersed.

  Lack of water can sometimes be a problem for plants in Madagascar. It appears that the baobab overcomes this by storing water within the fibrous wood of the trunk, as the tree's diameter fluctuates with rainfall.
