1.近年用红外激光技术研究液氢,发现液氢中含有H3+。
则H3+应该属于( )。
A.单质B.分子C.原子D.离子2.核外电子数一样、所显电性和所带电量也一样的微粒称为等电子等质子体。
以下各组内的两种微粒属于等电子等质子体的是〔〕A. Na+和Mg2+B. O2-和Mg2+C. F-和Cl-D. Na+和NH4+3.意大利科学家最近合成了一种新型的氧分子,其化学式为O4,对其说法正确的选项是〔〕A、O4是一种化合物B、O4是由O2组成的混合物C、O4是一种单质D、一个O4分子由2个O2分子构成4.食品标签上常常可以看到一些食品添加剂的名称,以下食品添加剂中会对人体安康产生副作用,必须严格控制用量的是〔〕A、亚硝酸钠〔发色剂〕B、山梨酸〔防腐剂〕C、苯甲酸〔防腐剂〕D、维生素〔营养强化剂〕5.对于化学反响A+B=C+D的以下说法中,正确的选项是:〔〕A、假设生成物C和D分别为盐和水,则该反响一定是中和反响B、假设A和C是单质,B和D是化合物,则该反响一定是置换反响C、假设A是可溶性碱,B是可溶性盐,则C和D不可能是两种沉淀D、假设A、B、C、D都是化合物,则该反响一定是复分解反响6.到高中我们将从元素原子得失电子的角度来认识氧化复原反响,而元素原子得失电子表现为元素化合价的变化。
因此可以把元素化合价有升降的化学反响确定为氧化复原反响,据此可判断以下化学反响不属于氧化复原反响的是〔〕A、Zn+CuSO4=ZnSO4+CuB、高温Cu+CO2C、Na2CO3+2HCl=2NaCl+H2O+CO2↑D、2KClO△2KCl+3O2↑7.*同学在实验报告中记录以下数据,其中正确的选项是〔〕A、用25mL量筒量取20.06mL盐酸B、用托盘天平称取5.25g食盐C、用100mL烧杯量取80.5mL盐酸D、用广泛pH试纸测得*盐酸溶液pH在3-4之间8.物质的性质决定物质的用途。

AMr. Read was born in a small village with high mountains all around it.He has few fields and he can’t get enough food for his family.He’s often worried about it.So he works harder and harder and tries his best to get more money.One afternoon,Mr. Read went out to look for some grass for his cows.It was very hot and he had to have a swim.Suddenly he saw a big tortoise in the water.He sw am there and caught it.The next morning he went to the town to sell it in the markets.When he was walking in the street, a car hit him down and he was hurt.He was sent to hospital at once.The doctors looked him over and had an operation on him.Two weeks l ater he felt much better.The doctors were satisfied with the operation and said,“You’ll be fully recovered in a week.We’re sure you can write when you leave hospital.”“It’s really a miracle(奇迹)!”shouted Mr. Read,“I could neither read nor write before!”1.The Reads have little food becauseA.they live in a small village B.they have few fieldsC.they’re too lazy to work D.nobody would help them to getmoney2.Mr. Read jumped into the river becauseA.he wanted to get some grass in the waterB.he wanted to look for a tortoise in the waterC.he wanted to have a good rest in the waterD.he wanted to have a swim3.Mr. Read’s was hurt in the traffic accident.A.head B.leg C.right hand D.left hand4.In Chinese the phrase“be fully recovered”meansA.完全覆盖B.全部找回C.恢复疲劳D.恢复健康5. What the doctor said meant that ______________ .A. he did a very successful operationB. the farmer was lucky enough to write after the operationC. the accident helped the farmer to writeD. he taught the farmer to write while he was stayin g in hospitalBHappiness is for everyone. You don’t need to care about those people who have beautiful houses withlarge gardens and swimming pools or those who have nice cars and a lot of money and s o on. Why?Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parent s are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice them, you can see that happiness is always around you.Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转) door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.1. Happiness is for_________.A. those who have large and beautiful housesB. those who have carsC. those who have a lot of moneyD. all people2. When you do something wrong, _______________.A. you may correct itB. you will have no chance to challenge yourselfC. anybody will laugh at youD. you will be happy3. Which is TRUE according to the passage?A. When you get success, your friends will be very proud of you.B. You can get help from others when you make mistakes.C. You can still be a happy person even if you have little money.D. All the above.4. Why do we say “Happiness is not the same as money”? Because ___________.A. money always brings happinessB. money doesn’t always bring happinessC. everything can be bought with moneyD. only rich people have happiness5. Which is the title of the passage?A. Do Something Good to OthersB. Happy and LuckyC. HappinessD. Life and SuccessCOne night, a little before nine o’clock, Dr Johnson was answering a telephone call.

At the railway station he learned that the next train to Glens Falls would not leave until 12 o’clock.It was after two o’clock in the morning when the doctor arrived at the hospital in Glens Falls. Miss Clarke, a nurse, was waiting for him.“I did my best,” said Dr Johnson. Miss Clarke said, “The boy died an hour ago.”They walked into the waiting room.

They jumped into the life-raft and watched the boat go under the water.For twenty days they had tins of food, biscuits, and bottles of water. They also had a fishing-line and a machine to make salt water into drinking water – two things which saved their lives. They caught eight to ten fish a day and ate them raw(生的). Then the line broke. “So we had no more fish until something very strange happened. Some sharks came to feed, and the fish under the raft were afraid and came to the surface. I caught them with my hands.”About twenty ships passed them, but no one saw them. After fifty days at sea their life-raft was beginning to break up. Then suddenly it was all over. A fishing boat saw them and picked them up. They couldn’t stand up. So the captain(船长)carried them onto his boat and took them to Costa Rica. Their two months at sea was over.1.

If we go into space, we see more and more of th e earth. People and man-made satellites have been sent out into space to look at the earth carefully and people have learnt more about the earth in the last few years.The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind.The sea is very big. It nearly covers three quarters of the earth. The sea is also very deep in some places. There is one place and at that place the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put into the sea at that place, there would be still 2 kilometers of water above it!In most parts of the sea, there are many kinds of fishes and plants. Some live near the top of the sea.Others live deep down. There are also a lot of small living things, and lots of fishes live by eating them.The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But, in 1970, five women scientists (科学家) lived in the deep sea for fourteen days.1.

初高中衔接试题推荐及答案【试题一:数学】题目:已知函数f(x) = 2x^2 - 3x + 1,求f(x)的顶点坐标。
答案:首先,我们可以将函数f(x)写成顶点形式,即f(x) = a(x - h)^2 + k。
对于给定的二次函数f(x) = 2x^2 - 3x + 1,我们可以通过完成平方来找到顶点。
完成平方后,我们得到f(x) = 2(x - 3/4)^2 - 1/8。
因此,顶点的坐标为(h, k) = (3/4, -1/8)。
【试题二:英语】题目:根据所给的中文句子,翻译成英文。
中文句子:春天是播种的季节,也是万物复苏的开始。
答案:Spring is the season for sowing, and it is also the beginning of the revival of all things.【试题三:物理】题目:一个物体从静止开始以恒定加速度运动,经过4秒后,其速度达到16m/s。
求物体的加速度大小。
答案:根据匀加速直线运动的速度公式,v = u + at,其中v是最终速度,u是初始速度,a是加速度,t是时间。
已知u = 0(物体从静止开始),v = 16m/s,t = 4s,代入公式解得a = (16 - 0) / 4 = 4m/s²。
【试题四:化学】题目:下列哪种化合物不是酸?A. HClB. H2SO4C. HNO3D. NaOH答案:D. NaOH。
NaOH是氢氧化钠,属于碱,不是酸。
其他选项A、B、C都是酸。
【试题五:生物】题目:细胞分裂过程中,染色体数量的变化规律是什么?答案:在细胞分裂过程中,染色体数量的变化规律是:在有丝分裂的间期,染色体复制,形成姐妹染色单体,但染色体数量不变。
在有丝分裂的后期,姐妹染色单体分离,染色体数量加倍。
在有丝分裂的末期,细胞分裂成两个子细胞,每个子细胞的染色体数量与母细胞相同。
结束语:以上是初高中衔接试题推荐及答案,希望能够帮助学生更好地过渡到高中学习阶段,掌握必要的知识点和解题技巧。

(共20分)注:主语(—)、谓语(=)、宾语(~)I hope you are very well. I'm fine, but tired. Right now it is the summer vacation and I'm helping my Dad on the farm. August is the hottest month here. It is the time of year for the rice harvest, so every day I work from dawn until dark. Sometimes we go on working after dark by the lights of our tractors. We grow rice in the south of the States, but in the north where it is colder they grow wheat. We have a lot of machines on the farm. Although the farm is large, my Dad has only two men working for him. But he employs more men for the harvest. My brother takes care of the vegetable garden. It doesn't often rain in the summer here. As a result, we have to water the vegetable garden. Every evening we pump water from a well. It then runs along channels to different parts of the garden.四、按要求翻译下列句子。
