A 英語中there be句型表示“有、存在”,不能和have連用；judging在此和telling用法同,都表示“判斷、區(qū)別”,但在這里不如telling地道.即修改為There seems to be; judging
C 如果以It seems to be開頭,則后面應(yīng)接difficult（形容詞）做表語,而題干中的意思顯然是“有……”；there be difficulty doing sth,這里用divide也不對(duì).應(yīng)該修改為There seems to be; dividing
D 以It seems that開頭的句型,后邊應(yīng)接從句；僅從語法看,這里應(yīng)修改為There seems to be; separating,但separate一詞一般不這樣用
