1、整理的OG10th的语法考点，希望能对准备考G的朋友们有所帮助。注：例句全为正确选项，多看看有利于培养语感。GMATOG(10th) SentenceCorrectionSampleQuestions1. TheWallersteinstudyindicatesthatevenafteradecadeyoungmenandwomentillexperiencesomeoftheeffectsofadivorcethatoccurredwhentheywerechildren.考点：从句，一次性行为，与时间
2、相关；分词多次性行为，与具体时间无关；when后面不能直接跟名词，whenachild,whenchildren都错。黄金规则15：作后置定语时，①定语从句表示一次性行为并与明确时间有关；②分词短语强调动作的重复性和多次性，且通常与时间无关。2. Since1981,whenthefarmdepression（农业衰退）began,thenumberofacresoverseenbyprofessionalfarm-managementcompanieshasgrownfrom48milliontonear
3、ly59million,anareaaboutthesizeofColorado.考点：主谓一致，thenumberof+复N+单V；from…to…固定搭配，不要用from…upto；同位语优先；无生命的事物通常没有所有格，如Coloardo’ssize错误。3. Somebatcaves,likehoneybeehives,haveresidentsthattakeondifferentdutiessuchasdefendingtheentrance,actingassentinelsandsoundi
4、ngawarningattheapproachofdanger,andscoutingoutsidethecavefornewfoodandroostingsites.考点：平行结构，doing,doing,doinganddoing;4. Theonlywayforgrowers（种植者）tosalvage（抢救）frozencitrusistohaveitquicklyprocessedintojuiceconcentratebeforewarmerweatherreturnsandrotsthefru
5、it.考点：简单句优先于并列句，并列句优先于复合句；theway+句子/inwhich+句子/todosth（做事情的方法）；citrus后为is,所以指代要用it,且能与growers区别开，避免指代不明。5. Carbon-14dating（碳14年代测定法）revealsthatthemegalithicmonuments（巨石纪念碑）inBrittanyarenearly2,000yearsolderthananyoftheirsupposedMediterraneanpredecessors.考点
6、：修饰问题，S…supposedMPV中，supposed修饰predecessors;如果是supposedly,则修饰Mediterranean,意思应该为“他所曾经被认为的地中海的祖先”，而不是被认为的地中海；有2000年的时间差异，所以要用olderthan,而不是asoldas.6. Invirtuallyalltypesoftissueineveryanimalspecies,dioxininducestheproductionofenzymes（诱导酶的产生）thataretheorganis
7、m’sattempttometabolize,orrenderharmless,thechemicalirritant（化学刺激物）.考点：trying有时可以做名词，但作为organism’s的宾语，不合语法，故用attempt，且与enzymes平行，句子中用“are”等同，attempttotry重复；thechemicalirritant宾语后置。7. Dr.Hakuta’sresearchamongHispanic（印第安人）childrenintheUnitedStatesindicatesth
