一、选择题(每小题3分,共40分)1. 已知函数f(x) = 2x^2 - 3x + 1,求f(2)的值。
答案:f(2) = 2(2)^2 - 3(2) + 1 = 92. 若a + b = 5,a - b = 1,求a的值。
答案:将两式相加:2a = 6,因此 a = 3。
3. 若log2 x = 3,求x的值。
答案:根据对数的定义,log2 x = 3可以转化为2^3 = x,因此x = 8。
4. 若三角形ABC满足AB = BC,∠ABC = 110°,求∠ACB的度数。
答案:由三角形内角和定理可得,∠ACB = 180° - ∠ABC - ∠BAC= 180° - 110° - 35° = 35°。
二、填空题(每小题4分,共40分)1. 设正实数a和b满足a + b = 10,且ab的最小值为3,则a的值为____,b的值为____。
答案:由平均值不等式可得:(a + b)/2 ≥ √ab。
代入已知条件,10/2≥ √3,得5 ≥ √3。
由此可知,a和b的取值范围为(5 - √3, 5 + √3)。
因此,a的值为5 - √3,b的值为5 + √3。
2. 若函数f(x) = a(x - 1)^2 - 1在区间[0, 2]上单调递增,则a的取值范围为____。
答案:由题意可知,函数在区间[0, 2]上单调递增,即f'(x) > 0,其中f'(x)为f(x)的导数。
对f(x)进行求导得到f'(x) = 2a(x - 1)。
根据导数的定义,当x ∈ [0, 2]时,2a(x - 1) > 0,解得 0 < a < 1。
因此,a的取值范围为0 < a < 1。

A tornado appears as a rotating, funnel-shaped (漏斗形的) cloud that extends from a thunderstorm to the ground with whirling winds that can reach 300 miles per hour. Damage paths can be over one mile wide and 50 miles long. Every state is at some risk from this disaster.Some tornadoes can be seen clearly, while rain or nearby low-hanging clouds obscure others. At many times, tornadoes develop so rapidly that little, if any, advance warning is possible.Before a tornado hits, the air may become very still. A cloud of debris (散片) can mark the location of a tornado even if a funnel can not be seen. Tornadoes generally occur near the edge of a thunderstorm, when the strong wind may die down. It is not uncommon to see clear, sunlit skies behind a tornado.The following are facts about tornadoes:☆The average forward speed of a tornado is 30 MPH, but may vary from still to 70 MPH. Debris is picked up or a cloud forms in the funnel.☆The average tornado moves southwest to northeast, but tornadoes have been known to move in any direction. Tornadoes are most often reported east of the Rocky Mountains during spring and summer months.☆Tornadoes can happen together with tropical storms and hurricanes as they move onto land. Waterspouts are tornadoes that form over water.☆Peak tornado season in the southern states of America is March through May; in the northern states, it is late spring through early summer. Tornadoes are most likely to occur between 3 pm and 9 pm, but can occur at any time.56. From the passage, we learn that tornadoes come from ______.A. hurricanesB. great heatC. thunderstormsD. sandstorms57.

At the entrance to a deep, dark cave, a few bats fly out. Then more and more of the small, furry creatures appear. Within a few minutes, a whole river of bats is pouring out of the cave, and they keep coming — millions and millions of them.Sound like a scary horror movie? Believe it or not, this scene takes place every night, all summer long, at Bracken Cave in Texas, where 20 million bats fly outside to feed on insects.Every March or April, Mexican free-tailed bats migrate up to 1,609 kilometers from their winter home places, like mines, tunnels, hollow trees, and under bridges in Mexico to this cave. Soon after they arrive, each mother gives birth to one baby bat. As many as 500 baby bats live crammed (挤) into one square foot of space, and those bodies create nice warm temperatures to keep them warm and comfortable. With bad sight, how can mother bats recognize their own babies? Their good sense of smell helps them the most.When the adult bats leave the cave at night to feed, they eat tons of insects in a single night, including many pests tha t eat farmers’ crops. And they get rid of mosquitoes, too.The cave, quiet in winter, is full of life all summer. The floor of the cave is covered with bugs. Gnats are flying around, and beetles are crawling up your leg when you walk in!When twenty million bats fly out of one cave opening, they make a column (柱) so thick that they show up on the radar at the nearby airport. So much for bats being scary!61. What is the purpose of the first paragraph?A. To explain the living habits of bats.B. To describe what bats look like.C.

Migration of Mexican free-tailed bats.CWhen I was in the eighth grade, one caring teacher of mine taught me several useful little techniques. He told me to keep a notebook nearby when I was reading and that I should try to figure out what the main idea of every paragraph was so that I could understand the passages better. It seemed awfully boring at that time, but I decided to give it a try anyway.It didn’t take long before I started reading a book called How to read a book that would completely change how I thought about the written word. Thanks to these techniques, I learned to get the most out of reading. I kept applying them over the years until I finally came up with a lot of little techniques for reading a book.I also eventually came to learn that there were a lot of different kinds of reading. For example, when I read a Stephen King novel, the interesting plot made me completely relaxed. Then there’s reading to learn new things, which is what I do when I read personal finance books. There’s also readi ng to understand and grow, which is easily the hardest and the most rewarding.The last kind of reading involves taking a piece of literature or a nonfiction book that you might read for simple pleasure and transforming it into something life-changing, or something that causes you to question some of your deeply-held ideas and beliefs.“How to read a book”really focuses on the latter two: books that you read to learn about a new topic or to learn a skill, and books that you read to learn about yourself. If you’ve ever been drawn to read to really improve yourself, this book is well wo rth the time to read even if it’s a bit dry at times. Let’s dig in.65.

If you want to learn about yourself, you may choose __________ to read.A. a Harry Potter bookB. a work of classic literatureC. a finance bookD. a fiction book68. The writer wrote the passage to _________.A. encourage readers to improve themselves by wide readingB. thank the teacher who once helped him improve his readingC. give an introduction to a very practical finance bookD. advise people to read a personal development bookDFor over twenty-five years, the Hulbert Outdoor Center has been dedicated (致力于) to helping teenagers enrich and change their lives through outdoor programs.
