几道英语选择题,求啊,准确率要高
9.He eats very [ ].a:about b:nice c:well d:fine
10.His sister's socks [ ] blue and white.a:am b:be c:is d:are
11.You can buy bags [ ] sports [ ] only 20 dollars.a:for,at b:about,for c:at ,for d:for,for

答案

C(A大约B漂亮D一般指身体方面好的)
d(am用于人称be是助动词is很明显是socks复数)
b(a选项at错了,表某一时段,c同a,d for是为...的意思)
小菜一碟
