The fact that economic hardship is the real source of many other problems is why the
revolutionary goverment attacked infatoin first.
这句话是不是把is和 why之间加上 the reason就是对的拉？否则就是错的？
对画线部分进行修改：
2 In the wild, pygmy chimanzees are found only in an inaccessibel region south of the
aire River, since such is the case, very few are in captivity
----------------------------------------------------------------
A since such is the case, very few are in captivity
B and very few are in captivity because of that
C no more than few are in captivity as a reasult
D the number in captivity is very few for this reason
E and so no more than a few are in captivity
答案为E，能解释一下其他选项为什么错了吗？作者: stephanie_sisu 时间: 2006-7-25 18:50:04
