19. ___________ one or more units of living substance called
protoplasm.
(A) In all living things consisting of
(B) All living things consist of
(C) Although all living things that consist of
(D) All living things consisting of
如果不懂語意(像我 沒背到protoplasm原生質這個字),想選(D),那句子後面要改,因為說明普遍現象、世界裡的原則不能用過去式~~ All living things (consisting of one or more units of living substance) are called protoplasm. 這樣的話語意是:所有生物都稱為原生質(,是由一種或多種生命物質單位組成的)。
