22、.B2.D3.B4.A5C【解析】試題分析:在英語中,當數(shù)次表示具體數(shù)字時,用單數(shù)形式。在讀超過一百的數(shù)字時,習慣讀法是在百位和十位之間用介詞and相連,其它數(shù)位一次讀出各級數(shù)位即可,選項ABD讀法有誤,故選C??键c:英語中數(shù)字的讀法點評:英語中數(shù)詞的應用有一些不同于漢語的規(guī)則,學習中應注意總結記憶。6.C7.B8.A。two and a half years也可說成two years and a half,意思都是“兩年半”。9.B10.B11.B12.D13B【解析】試題分析:“數(shù)字-名詞-形容詞”的結構表示的是符合形容詞,一般作定語。在這種結構中應注意兩點:一是用連字符,二是名詞必須用單

23、數(shù)。而“數(shù)字+名詞(復數(shù))+形容詞”的結構,一般做作表語。根據(jù)本題中的兩個空的位置可知,第一個是作表語,而第二個是作定語。所以本題選B。考點:本題考查固定用法點評:做本題時,比較容易選錯,許多學生不知什么時候用作定語,什么時候用作表語;有時有的學生還加以混用。所以對此應該準確掌握。14.D15B【解析】分數(shù)表示法為:分子用基數(shù)詞,分母用序數(shù)詞,分子大于1, 分母加s,在分子與分母之間可加連字符也可不加連字符,所以2/3表示為two-thirds 或two thirds ;分數(shù)在句中作主語時謂語和它修飾或指代的名詞保持一致。本題中two-thirds指代coats, 所以謂語用復數(shù)形式are。故

24、選B??键c:分數(shù)表達及主謂一致16C【解析】試題分析:根據(jù)題干,第一個空是分數(shù)。在英語中表示分數(shù)時,分子用基數(shù)詞,分母用序數(shù)詞,分子超過一的,分母要加s,故用排除AB;根據(jù)本句的主語 the land可知,此處應該用is。所以本題選C。考點:本題考查分數(shù)點評:題需要熟練掌握分數(shù)的表達方法;另外,第二個空前面題干比較長,需要認真分析本句的主語是什么,這是較難的。17B【解析】試題分析:英語中一般用基數(shù)詞表示分數(shù)的分子,用序數(shù)詞表示分數(shù)的分母。當分子是一時,分數(shù)的分母用單數(shù)形式,在表示分數(shù)時,當分數(shù)的分子大于一時,分數(shù)的分母要用復數(shù)形式。句意:地板的四分之三都濕了。有分數(shù)修飾的名詞的單復數(shù),與被修飾的名詞保持一致,floor作為地板講時,是不可數(shù)名詞。故謂語動詞用單數(shù),選B??键c:分數(shù)表達點評:英語分數(shù)的表達規(guī)則比較固定,學習中應牢記這些基本規(guī)則。需注意的是,由分數(shù)修飾的主語后面謂語動詞的數(shù),和被修飾主語的單復數(shù)保持一致。18D【解析】試題分析:句意:在我的公司每天大約有九分之二的員工開車上班。two-ninths九分之二,為固定表達,本句中主語為workers,為復數(shù)形式,謂語動詞用復數(shù)形式,故選D考點:分數(shù)的表達點評:英語中分數(shù)的表達,分子用基數(shù)詞,分母用序數(shù)詞,當分子大于1時,分母用序
