36.Most striking among the many asymmetries evident in an adult flatfish is eye placement： before maturity one eye migrates，so that in an adult flatfish both eyes are on the same side of the head. 來源：考試大
在一條成年比目魚身上顯著存在的諸多不對稱（asymmetry）特征中，最為吸人注目的是眼睛的擺位：在成年之前，一只眼睛發(fā)生移動，因此在成年比目魚身上，兩只眼睛均位于頭部的同一側(cè)面。 來源：考試大
37.The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the midocean ridge system， whose source，most geologists contend，is the upper mantle.
對于地幔分層論點來說，的證據(jù)乃這樣一個確認(rèn)的事實，即在那些海洋島嶼——這些島嶼據(jù)信是源于由下層地幔升上來的地幔柱狀溶巖流（mantle plume）——上發(fā)現(xiàn)的火山巖石，是由與海洋中部山脊系統(tǒng)的物質(zhì)根本不同的物質(zhì)構(gòu)成的，而這一海洋中部山脊系統(tǒng)的成因，大多數(shù)地質(zhì)學(xué)家論辯道，為上部地幔。
38.Some geologists，however，on the basis of observations concerning mantle xenoliths， argue that the mantle is not layered，but that heterogeneity is created by fluids rich in "incompatible elements" （elements tending toward liquid rather than solid state）percolating upward and transforming portions of the upper mantle irregularly，according to the vagaries of the fluids’ pathways. 來源：考試大
但是，某些地質(zhì)學(xué)家，以對地幔捕虜巖體（xenolith）所作的觀察為依據(jù)，指出地幔并非是分層排列的，相反，地幔的異質(zhì)性是由那些富含“不相容成分”的流質(zhì)構(gòu)成的，這些成分趨向于流體而非固體的狀態(tài)，自下而上滲透擴散，并依照這些流質(zhì)流向的任意性，不規(guī)則地將上部地幔的某些部分予以改變。
39.The very richness and complexity of the meaningful relationships that kept presenting and rearranging themselves on all levels，from abstract intelligence to profound dreamy feelings， made it difficult for Proust to set them out coherently. 來源：考試大
各種有意義的聯(lián)系在所有的層次上，自抽象的理性至深刻的夢幻般的情感，層出不窮并不斷重新組合排列；正是這些有意義的聯(lián)系的豐富性和復(fù)雜性，致使普魯斯特難于將它們錯落有致地安排好。
40.It is possible to make specific complementary DNA’s （cDNA’s）that can serve as molecular probes to seek out the messenger RNA’s （mRNA’s）of the peptide hormones. If brain cells are making the hormones，the cells will contain these Mrna’S. If the products the brain cells make resemble the hormones but are not identical to them，then the cDNA’s should still bind to these mRNA’s，but should not bind as tightly as they would to mRNA’s for the true hormones.
科學(xué)家可以制造出特異的（specific）互補DNA’s（cDNA’s），以此作為分子探子（molecular probe），探覓出肽激素的信使RNA’s（mRNA’s）。如果大腦正在制造著肽激素，則細胞就會含有這些信使RNA’s.假若細胞所制造的產(chǎn)品類似于肽激素但并非與這些肽激素全然相同，那么，互補cDNA’s應(yīng)仍然和這些信使mDNA’s粘結(jié)的程度。含有這些mRNA’s的腦細胞然后就可以被分離開來，研究者可對其信使RNA’s進行解碼，以確定它們的蛋白質(zhì)產(chǎn)品究竟是什么，并確定這些蛋白質(zhì)產(chǎn)品在何種程度上類似于真正的肽激素。
