暑假作业4-阶段检测(一)(含答案解析)

暑假作业4-阶段检测(一)一、单选题(共30分)1.我国嫦娥四号探测器发现月背含有丰富的核燃料—23He。
下列说法正确的是()A.23He和13H互为同位素B.23He的中子数为1C.23He的核外电子数为3D.He位于IIA族【答案】B【解析】【分析】【详解】A.质子数相同但中子数不同的核素互为同位素,而23He和13H质子数不同,不是同位素,故A错误;B.23He的中子数=质量数-质子数=3-2=1,故B正确;C.23He的核外电子数等于质子数=2,故C错误;D.He位于第一周期0族,故D错误;故答案为B。
【点睛】质量数=质子数+中子数;原子核外电子数=质子数=原子序数。
2.已知钡的金属活动性处于钾和钠之间。
则下列变化中可能实现的是()A.钡可从氯化钠溶液中置换出金属钠B.钡可从冷水中置换出氢气C.钡可从硫酸铜溶液中置换出铜D.在溶液中Ba2+可氧化金属锌,生成Zn2+【答案】B【解析】【分析】【详解】A.Ba先与溶液中的水反应,所以钡不能从氯化钠溶液中置换出钠,故A错误;B.Ba的性质活泼,能与冷水反应置换出氢而得到氢气,故B正确;C.Ba先与溶液中的水反应,所以钡不能从硫酸铜溶液中置换出铜,故C错误;D. 金属性Ba>Zn,则在溶液中钡离子不能氧化金属锌,故D错误;故选B。
3.已知下列元素的原子半径:根据以上数据,磷原子的半径(10-10m)可能是()A.0.80B.1.15C.1.19D.0.70【答案】B【解析】【分析】【详解】磷在周期表中位于硅和硫之间,因此半径也介于二者之间(1.02~1.17),选项中符合要求的只有1.15,故选B。
【点睛】本题考查了微粒半径大小的比较,注意电子层结构相同的离子半径大小的比较方法,同周期自左而右原子半径减小,同主族自上而下原子半径增大。
4.锗(32G e)与钾(19K)同周期。
下列说法正确的是70e的中子数与电子数的差值为38A.锗位于第~周期第ⅤA族B.G32C.锗是一种半导体材料D.碱性:Ge(OH)4>KOH【答案】C【解析】【分析】【详解】A、Ge的核外电子排布为2、8、18、4,则其位于第四周期IV A族,A错误;70e的中子数位38,电子数位32,则中字数和电子数的差值为6,B错误;B、G32C、Ge位于金属元素和非金属元素分界线上,其单质可用作半导体材料,C正确;D、第四周期中,Ge位于K的右侧,则K的金属性大于Ge,所以碱性:KOH>Ge(OH)4,D错误;故选C。

Diana Nyad was dozens of miles into her dream to complete a 103-mile swim from Cuba to Key West. Because of the currents in the Florida Straits, Nyad would have to last 60 hours-if everything went perfectly.For two years, this dream of swimming from Cuba to Florida had been part of her every waking hour. She was about to turn 60. "I wanted to be filled with commitment to the best of myself so that 1 wasn't looking back later saying, 'What have I done with my life?''' says Nyad.Those extreme physical struggles are not new to her. In 1974, 25-year-old Nyad became the first person to swim across Lake Ontario against the current. A year later, Nyad's 28-mile swim around the island of Manhattan made the front page of the New York Times."Physically, I'm stronger. I weigh a lot more," Nyad said after a training swim in Key West in June. "There are also mental advantages to being older," says Steven Munatones, an expert in swimming.Feeling a sharp pain in her right shoulder, she changed the angle of stroke (划), telling herself to go gently until her hand caught the water. In the 17th hour, she swam over to the boat, and the crew located a pain reliever. Nyad took it. She lay on her back, rolled onto her belly and continued swimming, and then she'd turn on her back again, gasping, unable to fill her lungs. "I'm trying to make it. I'm barely going forward. I feel so sick. This has been my dream forever, but I can hardly make it another hour," Nyad told David Marchant, the boat's navigator (领航员). Between the 23rd and 27th hours, Nyad had gone just five miles. "OK, Diana, I'm going to touch you, and it's going to be over," Stoll said. Nyad agreed. And with that, 29 hours and 43 minutes after she'd leaped into the water, the swim came to an end."She just wouldn't quit. It was more amazing to see her not make it the way she fought than if everything had gone exactly right and she'd made it the whole way," says Mark Sollinger, who piloted Nyad's lead boat.At a press .conference in Key West after being pulled onto the support boat, Nyad choked back tears and said, "Sometimes the will is so strong. But I was shaking and freezing, and I thought, 'There's no mind over matter anymore.'

The Inspiring AdventureBThe cost of raising a child from birth to age 18 is about $ 160,140! That doesn't even touch college tuition. For those with kids, this figure might lead them thinking how much they could have banked. For others, that number might confirm the decision to remain childless.But $ 160,140 isn't so bad if you break it down. It translates into $ 8896. 66 a year, $ 741. 38 a month, or $171. 08 a week.

You get to finger-paint, carve pumpkins, play hide-and-seek, and never stop believing in Santa Claus. You have an excuse to keep reading the Adventures of Piglet and Pooh, watching cartoons , going to Disney movies, and wishing on stars.For $ 160,140, you get to be a hero just for taking the training wheels off the bike, and coaching a baseball team that never wins but always gets treated to ice cream regardless.You get a front row seat to history; to witness the first step, first word, first date, and first time behind the wheel.You get to be immortal(不朽的)You get another branch added to your family tree.You get an education in nursing, criminal justice and communications that no college can match.In the eyes of a child, you rank right up there with God.You have all the power to correct a mistake, scare away the monsters under the bed, patch a broken heart, police a party, and love them without limits, so one day they will, like you, love without counting the cost.……25.

February 7 marked the 200th anniversary of his birthday. Yet for many, his language is old-fashioned and his stories often improbable. Then why do so many people know and read Dickens today?One reason is the British government's insistence that every child study a Dickens novel at school. Alongside William Shakespeare, Dickens is on every English literature school reading list.His stories, though often long by today's standards, are great moral tales. They are filled with colorful characters.Earlier this month, a ceremony was held in Portsmouth, where Dickens was born. Prince Charles said at the ceremony: " ...(Dickens) used his creative talents to campaign passionately for social justice... His characterization is as fresh today as on the day it was written."His books stand out from many other writers because of his insight (洞察力) into human nature. Dickens, like Shakespeare, tells us truths about human behaviour. They are as true in the 2Is1 century as they were to his readers in the 19th century.Readers have returned to Dickens' books again and again over the years to see what he has to say about their own times.No surprise then that it was Dickens whom Britons turned to during the economic crisis in the last couple of years. Dickens helped them make sense of a world that was rapidly falling apart. The BBC adapted one of his less well-known novels, Little Dorrit, into a popular television drama that introduced many Brits to the novel for the first time. A dark story about greed and money, it was the perfect illustration of bad times.As long as Dickens' novels have something to say to modern audiences, it seems likely that he will remain one of Britain's best-loved writers.29.

Which of the following statements is TRUE?A.Dickens' novels are still of realistic significance to today's world.B.Dickens' novels are of greater value during economic crisis.C.Dickens' works have gained more popularity than Shakespeare's.D.Some of Dickens' less well-known novels have been discovered recently.三、单词拼写33.–The TV seems broken.
