　　1.Now we must also examine the culture as we Mexican Americans have experienced it , passing from a sovereign people to compatriots with newly arriving settlers to , finally ，a conquered people a charter minority on our own land.

　　現(xiàn)在我們必須也按照我們墨西哥裔的美國(guó)人的經(jīng)歷來(lái)審視這個(gè)文化，我們的經(jīng)歷是從一個(gè)主權(quán)的民族變成了新來(lái)的定居者的同胞，在最終淪落成為一個(gè)被征服的民族在我們自己的土地上的契約的少數(shù)民族。難句類(lèi)型：復(fù)雜修飾、插入語(yǔ)、固定搭配

　　2. It is possible to make specific complementary DNAs that can serve as molecular probes to seek out the messenger RNAs of the peptide hormones. If brain cells are making the hormones，the cells will contain these MrnaS. If the products the brain cells make resemble the hormones but are not identical to them，then the cDNAs should still bind to　　these mRNAs，but should not bind as tightly as they would to mRNAs for the true hormones.

　　科學(xué)家可以制造出特異的互補(bǔ)DNAs，以此作為分子探子，探覓出肽激素的信使RNAs。如果大腦正在制造著肽激素，則細(xì)胞就會(huì)含有這些信使RNAs.假若細(xì)胞所制造的產(chǎn)品類(lèi)似于肽激素但并非與這些肽激素全然相同，那么，互補(bǔ)cDNAs應(yīng)仍然和這些信使mDNAs粘結(jié)的程度。含有這些mRNAs的腦細(xì)胞然后就可以被分離開(kāi)來(lái)，研究者可對(duì)其信使RNAs進(jìn)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(lèi)似于真正的肽激素。難句類(lèi)型：易混詞

　　3. The molecular approach to detecting peptide hormones using cDNA probes should also be much faster than the immunological method because it can　take years of tedious purifications　　to isolate peptide hormones and then develop antiserums to them.

　　采用cDNA探子來(lái)測(cè)定肽激素的這一分子生物學(xué)方法同時(shí)也應(yīng)該比免疫學(xué)的方法速度來(lái)得快，因?yàn)閷?duì)于免疫的方法來(lái)說(shuō)，需耗費(fèi)好幾年枯燥的提純進(jìn)程，方能將肽素分離了出來(lái)，然后再培養(yǎng)出針對(duì)它們的抗血清。難句類(lèi)型：復(fù)雜修飾、易混指代

　　4. Nevertheless, researchers of the Pleistocene epoch have developed all sorts of more or less fanciful model schemes of how they would have arranged the Ice Age had they been in charge of events.

　　然而，研究P時(shí)代的研究者發(fā)展除了各種各樣的或多或少有些奇怪思想的模型系統(tǒng)，用來(lái)顯示如果由他們來(lái)決定地質(zhì)事件的話(huà)他們將會(huì)如何安排冰川紀(jì)。難句類(lèi)型：復(fù)雜修飾、倒裝、修辭

　　5. This succession was based primarily on a series of deposits and events not directly related to glacial and interglacial periods，rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits.

　　這一序列演替所依據(jù)的，主要是一系列與冰川期和間冰期并不直接相關(guān)的地質(zhì)沉積物和地質(zhì)事件，而不是依據(jù)更為普遍的現(xiàn)代方法，去研究間冰層中所發(fā)現(xiàn)的生物殘留物，而這些間冰層本身又在冰川沉積物發(fā)生間層化。難句類(lèi)型：復(fù)雜修飾、省略、易淆指代

　　4. Nevertheless, researchers of the Pleistocene epoch have developed all sorts of more or less fanciful model schemes of how they would have arranged the Ice Age had they been in charge of events.
