legal language must not obscure the fact that _____A_______. Second, I will continue
on the path of repentance, seeking pastoral support and that of other caring people so that they can hold me accountable for my own commitment.

Underline the sentence which is not appropriate in the following paragraph.
A couple of days ago when I was in Florida a Jewish friend of mine gave me this liturgy book

28.
I want to embody those lessons for the children of this country. For leaves, birds and animals,
turning comes instinctively. But for us, turning does not come so easily. It takes an act of will for us to make a turn. It means breaking old habits. It means admitting that we have been wrong, and this is never easy.
29
But unless we turn, we will be trapped forever in yesterday's ways. I must always keep it as a caution light in my life. Lord help us to turn, from callousness to sensitivity, from hostility to love, from pettiness to purpose, from envy to contentment, from carelessness to discipline, from fear to faith.
.
30.

2020届中考英语阅读理解50篇 (绝对精品训练题，接近实战考题，值得下载练习) 1 When I was a kid in Minnesota, watermelon was expensive. One of my father’s friends, Bernie, was a rich businessman, who owned a large store in St. Paul. Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie’s place. We’d sit on the edge of the dock（码头）, feet dangling（摇晃）, and got ready for a big meal. Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we’d bury our faces in watermelon, eating only the heart—the reddest, juiciest, firmest, sweetest, most seed-free part—and throw away the rest. Bernie was my father’s idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie’s wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon. What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don’t take the time to dangle your feet over the dock and enjoy life’s small pleasure, your work is probably hurting your life. For many years, I forgot that lesson I’d learned as a kid on the loading dock. I was too busy making all the money I could. Well, I’ve relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That’s the heart of the watermelon. I have learned again to throw t he rest away. 1. We learned from the second paragraph that the writer and his father were feeling ______. A. relaxed B. worried C. hungry D. proud 2. How did the writer and his father eat the watermelon? A. They ate it in a polite way. B. They only ate its best part. C. They ate every part of it. D. They shared only one piece. 3. In the eyes of the writer’s father, Bernie ______. A. was just a rich businessman B. worked hard all the time C. lived a rich but healthy life D. knew how to make money

中考英语阅读理解100篇：中考英语阅读理解真题及答案（1） Edward rose early on the New-year morning. He looked in every room and wished a Happy New Year to his family. Then he ran into the street to repeat that to those he might meet. When he came back, his father gave him two bright, new silver dollars. His face lighted up as he took them. He had wished for a long time to buy some pretty books that he had seen at the bookstore. He left the house with a light heart, expecting to buy the books. As he ran down the street, he saw a poor family. “I wish you a Happy New Year.” said Edward, as he was passing on. The man shook his head. “You are no t from this country.” said Edward. The man again shook his head, for he could not understand or speak his language. But he pointed to his mouth and to the children shaking with cold, as if (好像) to say, “These little ones have had nothing to eat for a long time.” Edward quickly understood that these poor people were in trouble. He took out his dollars and gave one to the man, and the other to his wife. They were excited and said something in their language, which doubtless meant, “We thank you so much that we will remember you all the time.” When Edward came home, his father asked what books he had bought. He hung his head a moment, but quickly looked up. “I have bought no books”, said he. “I gave my money to some poor people, who seemed to be very hu ngry then.” He went on, “I think I can wait for my books till next New Year.” “My dear boy,” said his father, “here are some books for you, more as a prize for your goodness of heart than as a New-year gift” “I saw you give the money cheerfully to the poor German family. It was nice for a little boy to do so. Be always ready to help others and every year of your life will be to you a Happy New Year.” 48. Edward expected to _________ with the money he got from his father. A. help the poor family B. buy something to eat C. buy some pretty books D. learn another language 49. Why did the poor man shake his head when Edward spoke to him A. He couldn’t understand the boy B. He wouldn’t accept the money C. He didn’t like the boy’s language D. He was too cold to say anything

第1周(第五章:函数依赖、推理规则、闭包) 二、研讨课: 1、假设员工关系EMＰ(员工号,姓名,部门,部门电话,部门负责人,家庭住址,家庭成员,成员关系)如下表所示。如果一个部门可以有多名员工,一个员工可以有多个家庭成员,那么关系EMP属于数据冗余问题;为了解决这一问题,应该将员工关系EMP分解为(员工号,姓名,部门，家庭地址,家庭成员,成员关系)(部门,部门负责人,部门电话), 画出ER图(上学期学过了,很简单，懒得画),主外键（主键：员工号,外键：部门)(主键： 2、判断Ｆ＝{Ａ->ＢC,Ｂ-＞Ａ,AＤ－>E｝与G={A－＞BC,B->A，BD->Ｅ｝就是等价得 因为B－＞A,所以BD－>AＤ,因为AD-＞Ｅ，所以BD->E,所以。。。 3、设关系模式R具有ｎ个属性,在模式R上可能成立得函数依赖有 (1) 个?其中平凡得ＦD有 (２）个?非平凡得FＤ有（3) 个？以上3点都需说明为什么 三、作业: 1、设函数依赖集F={AB－>Ｅ,ＡＣ-＞Ｇ,ＡD-＞BG,B->C，C-＞D｝,试证AC->G就是冗余得。 AD->ＢＧ，C－>Ｄ,所以ＡC->BＧ,所以AC－>G,所以冗余 2.课本Page124:习题5、3 （1)X->?永远满足。 (２)?->Ｙ,则属性Ｙ对于各元组得值相同。 （３)?->?为平凡得函数依赖,永远满足。 3、课本Ｐage1２4:习题５、8 证明:(反证法)假设存在A→Ｂ 那么 A→AB, 关系模式R得候选码即为A,不就是全码 ∴假设不存在,Ｒ不满足A→B
同理：R不满足 B→A ?第２周(第五章：、关键码、最小函数依赖集） 二、研讨课: 2.设有函数依赖集:F={AB->C,C->Ａ,BＣ->D,ACＤ－>Ｂ,Ｄ->ＥＧ,BE->C,CＧ-＞BD,ＣE-＞AＧ},计算其等价得最小依赖集。 1、把右边都写成单属性 AＢ->C,Ｃ->A,BC->D,ACD->B,D->Ｅ,D－>Ｇ,BE->C，CG->B,CＧ->D,CE->Ａ,ＣE->G ２、去左边冗余属性 Ｃ－＞Ａ,CE->Ａ冗余,去掉CE->A,所以 AB－>Ｃ,C->Ａ,BC->D,ACＤ->B,D->Ｅ,Ｄ->G，BE->C,ＣG－>B,CG-＞D,CE-＞G 3、去冗余得FD D-＞G,所以CD－＞CG,ＣG->B,所以CD->B,所以ACＤ－>B，所以ＡCD->B冗余 所以 AＢ->C,Ｃ－>A，BＣ->Ｄ,Ｄ－＞Ｅ,D->Ｇ,ＢＥ－>Ｃ，CＧ-＞B,ＣG－>D,ＣE->Ｇ3．已知R(ABCDE),F={Ａ→B，BC→A，A→Ｄ},求R得全部非主属性。 L:C R：D N:Ｅ LR:A,B CE+=CE AＣＥ＋＝ABCＤE BCE＋=ＡBCDE 所以非主属性为D 三、作业： 1、已知Ｆ=｛B→D,A→Ｄ,DＡ→ＣB,CＤ→Ａ},求Fmiｎ。 1、右边单属性 Ｂ→D,A→D，DA→C,DA→B，ＣD→A 2、左边冗余属性 A→Ｄ，DＡ→C,ＤA→B，所以A→C,Ａ→B 所以 B→Ｄ,A→Ｄ,A→C，A→B,CD→A ３、冗余得ＦD:无 ２、如果关系模式R(A,B)得候选码为(A,B)(即为全码),那么该关系模型一定不满足A→B,或Ｂ→Ａ。 没什么好说得 3、设有R(ＡBCＤE),Ｆ={ A→C,Ｂ→C，C→D,CE→A，DE→C },求候选码。 L：B,E R: Ｎ： ＬR：A，C,D ＢE＋=ABＣDＥ 所以BE
