右图是在低倍镜下观察到的影像,要把字母移到视野中央,应将玻片往哪个方向移

A.右上方

B.右下方

C.左上方

D.左下方

答案

答案:D

题目分析:在显微镜下看到的物像是上下左右均颠倒的物像,所以移动玻片标本时,标本移动的方向正好与物像移动的方向相反,图中物像位于视野中央偏左下方,要想把它移到视野中央,应该向左下方移动玻片标本,物像才向右上方移动移到视野中央。

点评:此题为基础题,解答此类题目的关键是理解显微镜的成像特点。

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

A

A few years ago, when I was still in high school, I met a wonderful and warm teacher. At that time in my life, there were many changes to adjust to, apart from the usual teenage troubles. My parents had divorced, so my elder brother and I had chosen to stay with my dad. Due to the fact that he was keeping the house, we didn’t have to move.

During this time, my teacher took a special interest in me. Being my English teacher, she encouraged my mind to travel to creativity I had long given up. She brought me out of the shell I built.

She became my mother, my older sister, my friend and my teacher. The one thing she couldn’t do though was to make me more girly as growing up with only my dad and brother made me a real tomboy.

Sometimes, I would be really immature(不成熟的), especially if she was scoring me less than others on purpose. She knew I could do better than what I was handing in and so pushed me to extend further than limits.

When I finished school and then after college I was about to leave my hometowns she gifted me a watch that every second, with my pulse, should remind me of the one person who will forever wait and love me without reservation.

Time has passed and our friendship is distant, but in my heart, soul and mind, she is the closest I ever got.
