We ______English lessons on Saturday morning.
A．don’t haveB．haven’tC．a(chǎn)ren’t haveD．no have
A

試題分析：根據(jù)時間狀語on Saturday morning可知此句要用一般現(xiàn)在時，由選擇項(xiàng)的提示可知要用否定形式，且謂語動詞是have，故其謂語動詞的否定形式要借助助動詞do，故用A。
點(diǎn)評：學(xué)生要注意一般現(xiàn)在時句子中行為動詞的否定句的構(gòu)成，尤其特別是當(dāng)主語為三單形式時謂語動詞的否定句結(jié)構(gòu)，謂語動詞要用原形。
