1、2024年黑龙江省大庆市杜尔伯特蒙古族自治县中考二模英语试题一、阅读理解About 80% of people do not get enough vitamin (维生素) D every day. But this vitamin is very important for your health.Vitamin D is really important for our bones (骨骼). When we are young, vitamin D builds up our bones and makes them strong. When we are older, we stil
2、l need vitamin D to keep our bones strong. Our bodies keep the vitamin D in our bones and teeth. Then we lose vitamin D as we work and exercise during the day. But our bodies cant make vitamin DSo we have to get it from outside of our bodies.Where can a person get this very important vitamin? Vitami
3、n D is in foods like fish and eggs. Sometimes, vitamin D is added to bread, milk, and orange juice. Food is not the only way our bodies can get vitamin DThe sun also gives us vitamin DIf we want to be healthy, we should spend some time in the sun each day. Too much sun is not good for you, but about
4、 15 minutes a day is usually enough. And we should be sure to eat foods that are rich in vitamin D, too.1Why do we have to get vitamin D from outside of our bodies?AIt makes us popular.BIt helps us eat more food.COur bodies cant make vitamin.DThe more vitamin D, the better.2According to the writer,

Can you do addition and sub
6、traction (加法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater math abilities. After some training, they can know the difference between even numbers (ending in 0, 2, 4, 6 and 8) and odd numbers (ending in l, 3,5, 7 and 9).Some Australian scie
7、ntists put up different cards with an odd or even number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sugar water; if not, it got bitter wa
8、ter.In a short time all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the t
9、ime. Surprisingly, the bees even learned odd numbers more quickly than humans.How did the bees learn the numbers so fast? Scientists believe that finding the answer will help them build better and faster computers. But they dont have a clear idea yet. In fact, a bees brain is much smaller than ours!
10、4How did the scientists show the numbers to the bees?ABy cards with different colors.BBy cards with different numbers.CBy cards with pictures of flowers.DBy cards with pictures of triangles.5What does the underlined word “bitter” mean in the text?ANot hot.BNot cold.CNot sour.DNot sweet.6What was the
11、 result of adding new numbers 11 and 12?AThe bees could no longer recognize any numbers.BThe bees could choose correctly 70% of the time.CThe bees could not recognize these new numbers.DThe bees could choose correctly 80% of the time.7What do we know about bees?ABees brain sizes are similar to human
12、s.BBees learn odd numbers more quickly than humans.CBees cannot tell odd numbers from even numbers.DBees prefer even numbers more than odd numbers.Do you know about bioplastic (生物塑料)? It is a kind of plastic. But it is different. Normal plastic is made from chemical materials and takes a very long t
13、ime to degrade. But bioplastic is good for the environment. It is made by using bacteria (细菌) to process natural sources like vegetable oils, corn or sugar. It can degrade more easily.But there is a problem with bioplastic. The “food” that bacteria eat is also what we eat. This means that bacteria a
14、re competing against humans for the same resources.Now scientists have found a new way to make bioplastic using two kinds of bacteria and sunlight, according to Newsweek.One of the bacteria is called synthetic cyanobacteria (合成蓝藻), which can use sunlight to produce sugar. The other kind is Halomonas
15、 boliviensis (玻利维亚盐单胞菌), which lives in the salty waters of Bolivia. It eats the sugar that the first bacteria produce and then it can produce polymers (聚合物). Polymers are used to create bioplastics. The way the bacteria store polymers is similar to how humans store fats.Producing bioplastic with th
16、ese two bacteria has many advantages. It is 20 times faster than the normal way we produce bioplastic. Also, using these two bacteria saves resources.First, producing large amounts of bioplastic requires corn and sugar, which are used to feed normal bacteria. And growing corn and sugar needs farmlan
17、d. But these two special bacteria can just use sunlight. The land that is saved can be used to grow food for humans.Besides, this process doesnt need rich land or clean water at all, scientists said to Newsweek. The next challenge scientists face is that they want to put their lab research into real
18、-world practice. By doing this, bioplastic made with these two bacteria can be widely produced in the future.8Compared to normal plastic, bioplastic _.Ais easier to processBis easier to degradeCproduces no wasteDuses more materials9What problem can bioplastic cause?AHumans might have less food to ea
19、t.BIt helps spread harmful bacteria.CPeople are afraid to use bioplastic.DIt leads to the overuse of chemical materials.10What advantages can the new way of making bioplastic have?AIt only requires farmland.BIt saves time and resources.CIt helps kill harmful bacteria.DIts process produces lots of fa
20、ts.11What is the main idea of the story?ABacteria can be environmentally friendly.BBacteria are competing with humans for resources.CScientists invented a better way of producing bioplastic.DScientists introduced a new way to fight bacteria.Smartphones are getting boring. The new models are either a
21、 bit faster or have better cameras, but they are basically no different from the ones already in our pockets. This is why scientists are hoping, and working for something new, something that will change our lives just as greatly as smartphones do. At the moment, the next invention might be smart gla
22、sses. Just imagine. Instead of having to pick up your phone and look at the screen, all of the information you need simply appears just in front of you, in your glasses. Satellite navigation (导航) directions would appear right there on the road. And your smart glasses could guide you to th
23、e right shelf in the supermarket! Smart glasses could also be used in industry. They could show engineers the instructions they need to fix things more quickly. A doctor could carry out a difficult operation, guided in real time by someone on the other side of the world.This may sound impossible. Bu
24、t most of the technologies to invent them are already there. For example, one key technology is called AR, which can make digital 3D objects appear as if they are part of the real world. Weve used it a lot on our video calls. Similarly, huge progress has been made in spatial audio. This is when a so
25、und is made to give it a sense of place, like what you hear in an empty room. Some high-end earphones can already do that. Future glasses will of course need to recognize (识别) your voice to do tasks. This technology has been widely used in our daily life.So, why arent we all wearing smart glasses ye
26、t? So far, no one has invented a good way to send images (映像) of our world onto glasses. However, with the rapid development of technology, smart glasses could arrive much sooner than we think.12Why does the writer mention smartphones in Paragraph 1?ATo start a story.BTo explain an idea.CTo introduc
27、e a topic.DTo discuss a problem.13What are Paragraphs 2 and 3 mainly about?AWhen smart glasses might be made.BWhere smart glasses could be used.CHow smart glasses would give directions.DWhy smart glasses should be changed.14Which of the following technologies needs to be improved to invent smart gla
28、sses?AMaking spatial audio.BRecognizing voices.CCreating digital 3D objects.DSending images onto glasses.15How might the writer feel about the future of smart glasses?ABored.BConfident.CSatisfied.DUncertain.根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。How to stay in a good mood (心情)Put some fresh and be

36、“Maybe I could guard my honey 25 with a weapon, like a stinger (螫针) or something.”Jupiter grew 26 . “You mean youd use a stinger against the gods? Or even against me?”The little bee was scared. As he quickly moved backwards, he bumped into (撞上)
37、Juno, the wife of Jupiter, queen of all the gods, who was standing nearby and listening.After tasting the honey, she said, “This amazing food needs some 27 , of course!” Juno agreed. “I think you should give each bee a stinger. But there must be a price for using it: If a
