现在进行时的被动语态有时可表示按计划或安排将要进行的一个被动动作(此种用法仅限于少数及物动词，如：hld，take等)。

(3)不及物动词(短语)、非延续性动词、表示存在意义/所属关系/静态特征的动词以及系动词不用于现在进行时的被动语态。

Ⅴ.七选五
Animals can mve frm place t place，but plants cannt.When an animal is under attack，it can run away r fight back.Plants certainly cannt run away，and they lack teeth and claws. 33
Sme plants have their wn ways t keep animals away.Fr example，the leaves f the hlly plant have sharp spines(刺) that discurage grass-eating animals.Hlly leaves n lwer branches have mre spines than leaves n upper branches. 34
Sme plants，such as the ak tree，have thick and hard leaves that make it difficult fr the animals t eat.Sme grasses may cntain a sandy material. 35
Many plants als have chemical defenses. 36 Sme plants may fight against an attack by increasing the prductin f these chemicals.When a wrm bites a tbacc leaf，the leaf prduces a chemical messenger.This messenger sends t the rts the infrmatin t prduce mre nictine.The higher levels f nictine discurage the wrm.
37 A certain plant in China，fr example，has physically spiny leaves，and each spine cntains chemically pisnus venm(毒液)．A single experience with this kind f plants will teach an animal t stay away in the future.
A．Animals are gd at prtecting themselves.
B．Eating such grasses wears dwn animals’ teeth.
C．Many plants depend n bth physical and chemical defenses.
D．Plants have mre ways t defend against the enemies than animals.
E．This is because the lwer leaves are easier fr mst animals t reach.
F．Sme plants prduce chemicals that taste bitter r cause an unpleasant reactin.
G．But plants can defend themselves by using bth the physical and chemical means.
eq \x(语篇解读 本文主要介绍了植物保护自身免遭动物伤害的方法。)
33．答案 G
解析 该句位于首段段末，应能起到引出下文内容的作用。下面的几段均介绍了植物保护自身免遭动物伤害的方法，且该空前的三句介绍了与动物相比植物的劣势，故G项(但植物可以通过使用物理和化学方法对自己进行保护)符合此处的语境。
34．答案 E
解析 上一句中提到较低处的冬青树叶比较高处的叶子有更多的刺，而E项(这是因为较低处的树叶更容易被大多数动物够到)紧承上文，介绍了原因。
35．答案 B
解析 上一句中提到有些草可能含有沙质物质，而B项(吃这些草会磨损动物的牙齿)恰能顺承上文。
36．答案 F
解析 第四段主要介绍了有些植物能够使用化学防御方式来抵御伤害。结合下一句中的“by increasing the prductin f these chemicals”可知，该空应点明有些植物能够产生一些味苦或者会引起不良反应的化学物质，即F项。
37．答案 C
解析 下文的例子中提到的植物既有“physically spiny leaves”，又有“chemically pisnus venm”，由此可见，本段介绍了有些植物既依靠物理方式也依靠化学方式抵御侵害，故选C项。1．What is being dne t help them?
2．I knw that they’re being hunted and their habitat is getting smaller.
3．What measures are being taken t help them?
4．They are being hunted，illegally，fr their valuable fur.
5．Much is being dne t prtect wildlife，but if we really want t save the planet，we must change ur way f life.
