(
C
)2.— ______ coat is this? — It's my brother's.
A.Who
B.Who's
C.Whose
答案:C
解析:
本题考查特殊疑问词的用法。根据答语“It's my brother's.”(它是我哥哥/弟弟的),可知问句是在询问这件外套是谁的。A选项“Who”意为“谁”,用于询问人;B选项“Who's”是“Who is”的缩写,意为“谁是”,用于询问人的身份;C选项“Whose”意为“谁的”,用于询问物品的所属关系。因此,正确答案是C选项“Whose”。
( )3.[跨学科题]按规律填入数字的英文形式:1,2,3,5,
eight
,______
thirteen


A.nine; eleven
B.eight; thirteen
C.eleven; ten
答案:B
解析:
观察数列1,2,3,5,发现从第三项开始,每一项都是前两项的和。即3=1+2,5=2+3,所以下一个数应该是3+5=8,再下一个数是5+8=13。将数字转换为英文形式,8是eight,13是thirteen。

A
)4.It's time ______ go home. Let's go.
A.to
B.for
C.with
答案:A
解析:
本题考查“It's time”的固定搭配用法。“It's time to do sth.”表示“是做某事的时候了”,后面接动词原形;“It's time for sth.”后面接名词。本题中“go home”是动词短语,所以要用“It's time to do sth.”这个结构,故应选“to”。

)5.Look at these birds in the tree. Please come and play with me.读句子,请找出画线部分发音不同的一项。
A.these
B.come
C.me
答案:B
解析:
these中"e"发音为/iː/,come中"e"不发音,me中"e"发音为/iː/。B项发音不同。
