33.D.推理判斷題.根據(jù)第一段It's hard to imagine how a single-celled blob (單細(xì)胞斑點)in the ocean evolved into a fish*a turtle,or eventually a human.2.5billion years ago,lives on Earth were all single-celled.Then,these tiny creatures started getting bigger,evolving into multi-celled blobs that eventually became animals可知文章主要講單細(xì)胞斑點的進(jìn)化;故選D.
34.B.細(xì)節(jié)理解題.根據(jù)第一段Multicellularity is one of the most important steps in evolution,but it's hard to study because tiny blobs in the ocean don't really leave fossils behind可知科學(xué)家研究多細(xì)胞生物的過程難是因為他們在海里找不到任何化石;故選B
35.A 細(xì)節(jié)理解題,根據(jù)文章Scientist Nicole King thought that the choanoflagellaes used this glue to hold themselves to the surlace of water可知領(lǐng)鞭毛蟲的鈣粘蛋白用于維持身體表面的水;故選A
點評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷.
