At that point, I had the full intention of asking for something, but for the first time, I realized how lucky I was to have been born in such a fortunate family. There was nothing I could ask for because there was nothing more I needed, materialistically nor emotionally. I was truly satisfied.This made me think about all the children who did not have families, homes, or food, much less gifts, for Christmas. With these thoughts in my mind, I told my parents in January that instead of getting me an expensive gift for the holidays, I’d love to use the money to get a bunch of small gifts for all the childr en that hadn’t gotten anything for Christmas.At first, they were shocked. Then they realized I was serious, and agreed to spend $500 ongifts for young kids of the families living at the homeless shelter. It was such an incredible experience. I remember going to the homeless shelter to hand out the toys to as many kids as we could give, asking them all to share. One of the children looked at me with his innocent eyes. I could see the astonishment in them. It was obvious that he had never gotten a Christmas gift before, so when he asked me where I got the gifts from, I told him what I knew he wanted me to say: that I was helping Santa.I explained that Santa was sorry he was so late, but that this gift had been made especially for him! The boy took the gift slowly, smiled the cutest smile I had ever seen and ran to his mother.The last thing I heard as I moved on to give a gift to the next hopeful child was the boy’s voice: “Mommy, Santa really does exist! And he didn’t forget about us this year! ”1. What can we learn from the first paragraph?A. The author wanted a Christmas gift.B. The author is very happy.C. The author was worried to get nothing.D. The author’s family is in poor condition.2. When the author thought of those homeless children, he .A. wanted to stay with themB. wanted to spend Christmas with themC. wanted to buy gifts for themD. wanted to visit them3. How can you describe the children when they got Christmas gifts?A. Surprised.B. Excited.C. Interested.D. Depressed.4. Which of the following statements is NOT true according to the passage?A. Hearing he wanted to buy gifts for the homeless children, the author’s parents felt shocked.B. The author’s parents agreed to buy gifts for the homeless children.C. The homeless children never got Christmas gifts before.D. One of the boys thought Santa really doesn’t exist.Ⅲ. 书面表达(2021·齐齐哈尔二模)目前青青年压力过大, 为排解压力, 一些青青年染上了一些恶习, 如抽烟、饮酒等, 请你以学生会的名义参照以下提示用英语写一封建议书, 呼吁中学生要“养成好适应, 健康过生活”。

3
答案:x+2y=0
(2)因为两直线l1:mx+8y+n=0与l2:2x+my-1=0相交,因此,当
m=0时,l1的方程为 y
n 1 ,l2的方程为 x ,两直线相交,此 8 2
时,实数m、n满足的条件为m=0,n∈R;当m≠0时,∵两直线 相交,∴ m 8 ,解得m≠±4,此时,实数m、n满足的条件为
存在.
距离公式的应用 【方法点睛】
1.两点间的距离的求法
设点A(xA,yA),B(xB,yB),
AB
xA xB
2
yA yB .
2
特例:AB⊥x轴时,|AB|=|yA-yB| AB⊥y轴时,|AB|=|xA-xB|.
2.点到直线的距离的求法
可直接利用点到直线的距离公式来求,但要注意此时直线方程
求两直线的交点坐标,就是解由两直线方程组成的方程组,以
方程组的解为坐标的点即为交点.
2.过直线A1x+B1y+C1=0与A2x+B2y+C2=0交点的直线系方程
A1x+B1y+C1+λ (A2x+B2y+C2)=0.(不包括直线A2x+B2y+C2=0)
【例1】(1)求经过直线x+y+1=0与直线x-y+3=0的交点,且也经
1 2
a 0
2
5 10 17 ,解得:a=±8;
2
(3)因为两平行线方程可化为:2x-y=0与2x-y+5=0.
|50| 因此,两平行线间的距离为: d 5. 2 2 2 1
答案:(1) 5
(2)±8

But there weremillions of them, which was why dad was so anxious toget rid of them.“They’re totally destroying our beans, ”he toldMom over lunchtime on e Saturday. “I’ve been tryingto keep t hem out of the tomatoes, but I don’t know ifI can make it. ”“Isn’t there something you can do about them? ”Mom asked. She was mostly concerned about the tomatoes. “I think there’s a spray(喷雾)or something, ”Dad said. “I’m going down to the garden center after lunch and see if they have any suggestions. ”I’m pretty sure that’s what he said. But what I heard was, “While I’m gone, why don’t you and George come up with your own plan for getting rid of the grasshoppers? ”And so that’s what we did.It was the summer between fifth and sixth grade, so we were feeling pretty clever and mature. Certainly we knew how to get rid of these grasshoppers. That seemed simple enough. Finally Ron and Don joined us but then, things got a little crazy. Before we knew it we were doing terrible experiments. I won’t describe our experiments. Let’s just call it“The Adventures of the Marquis de Orkin”. Dad came home and saw these different deaths. We were laughing, but the laughter quickly t urned to silence when we saw the look on my Dad’s face.“What are you boys doing? ”he asked.“We’re just sort of helping to get rid of the grasshoppers, ”I said.“This isn’t getting rid of grasshoppers, ”Dad said. “This is killing. ”I was confused. I looked at the insectici de he was carrying. “But aren’t you going to kill grasshoppers with that? ”I asked.“Yes, because it’s something we need to do for the protection of our garden, ”he said seriously. “But I’m not going to enjoy it. ”【文章大意】本文是一篇记叙文。
