V. 阅读理解
Have you noticed that people speak differently to babies compared to adults Carers, especially mothers, change their speech when talking to young children. How Their speech includes higher pitches (音高) and a wider pitch range (范围). They use shorter sentences and repeat words more often. You can think of it as baby talk. Researchers have recently discovered that dolphins also use baby talk with their babies.
The research team recorded sounds of 19 mother dolphins living in the Sarasota Bay area. The sounds of the same female dolphins were compared when they were with and without their babies. Chart 1 shows the sound of a female dolphin without her baby. The researchers found that when dolphins were with their babies, dolphin mothers had a wider range of frequencies (频率) of the sound—the maximum (最高) frequencies were higher and the lowest frequencies were lower.
The findings mirror the way that humans change the speech when speaking to babies. Dolphin "baby talk" may have a similar purpose to human "baby talk": it may help babies learn how to phonate. We humans don't only "baby talk" with little babies, but with the children who are still learning to speak. As a result, our children are able to talk. That's exactly what happens to dolphins. The changes in speech don't just happen when dolphin mothers stay with very young babies, but also between mothers and babies that are closer to "toddler (蹒跚学步的孩子)" age. Another possible reason for using specific pitches is to catch the children's attention. It's really important for a young dolphin to know "Oh, Mum is talking to me now."
The research about baby talk in dolphins reminds us how important it is in humans. Whenever we speak with a young child, how we say things could be as important as what we say.
1. What's one of the features of baby talk according to the first paragraph
A. Lower pitches.
B. Longer sentences.
C. A smaller pitch range.
D. More same words.
2. Which chart shows the sound that dolphin mothers make when with babies
3. What does the underlined word "phonate" mean in Paragraph 3
A. Produce the sound.
B. Understand baby talk.
C. Change the speech.
D. Catch people's attention.
4. Why does the writer write this passage
A. To help people understand the sounds made by dolphins.
B. To ask people to build a good relationship with dolphins.
C. To remind people to communicate with children more often.
D. To let people be careful with the way of talking with children.

Imagine spending your nights sleeping thousands of times, each time for only four seconds. Does it sound like a nightmare 1.
Like other penguins, chinstrap penguins spend much of their time in the water. But when the time comes to raise their young, they return to land to build nests and lay eggs. Usually, one parent guards the nest while the other hunts for food. The "guarding parent" must always keep an alert (警惕的) lookout. 2. Getting a good night's sleep can be deadly for the young, but it's hard to stay alert for 20 hours a day. Chinstrap penguins have found an unusual way to solve the problem.
In a new study, scientists report that chinstrap penguins take thousands of "micro - sleeps" every day. 3. By taking over 10,000 microsleeps a day, the penguins get a total of about 11 hours of sleep a day.
Niels Rattenborg is one of the scientists. He says the penguins are always "blinking" their eyes. 4. Dr Rattenborg says it's amazing how they can keep guarding their nests, eggs, and babies while sleeping like this.
5. Do these microsleeps help the penguins feel truly rested, or just help them stay alive Do they sleep this way only when they have babies, or at other times too More studies are needed to learn about these birds that cannot fly.
A. But scientists still have questions
B. Each sleep lasts only about four seconds
C. They do this around the clock for several weeks at a time
D. Well, that's exactly how chinstrap penguin parents sleep
E. Scientists have found that other penguins also have similar sleeping habit
F. Because some skuas (贼鸥) like to attack the eggs and young penguins
G. More researches need to be done to study the sleep mode to help chinstrap penguins
1. ______ 2. ______ 3. ______4. ______ 5. ______

(2025·上海一模)They are summer - time singers. They're found e 1 except in the North and South Poles. And even though they're common, they're also quite fascinating. Who are they Grasshoppers!
A 2 Body Grasshoppers have an exoskeleton (外骨骼) which means the skeleton is on the outside of their body. They have two sets of wings. The front pair is h 3 and strong, like a shell. The back pair is soft and flexible, which allows the grasshopper to c 4 directions quickly and smoothly during flight. The grasshopper also has three pairs of very strong legs. They use these to walk and to jump 20 times their own body length. Imagine if you could do that!
Have you ever tried to catch a grasshopper You won't even have a c 5. It's because they have five eyes in total, which help them see in almost every direction. This means they h 6 miss noticing any danger coming.
Music Makers If you hear a pleasant chirp (唧唧声) on a summer night, it could be a male grasshopper trying to attract a female one, or ask other males to stay away. It p 7 the sound by rubbing the back leg against its forewing, just like playing the violin. Next time you hear the chirping sound in summer, remember it's a grasshopper's l 8 song or a warning call.
Friend or enemy Some grasshoppers like the taste of wheat, corn and cotton—all things we use and farmers hate to l 9. In fact, a large group of grasshoppers called locusts (蝗虫) can quickly and easily eat up a farmer's crops in just a few minutes.
H 10, not all grasshoppers are monsters. A type of grasshoppers called Turnbull helps control the growth of weeds (野草) by eating them. The Two - Striped grasshoppers eat plants that are harmful to cows.

V.1-4 DDAD
【语篇解读】本文是一篇说明文，介绍了一项研究发现，海豚妈妈在与宝宝交流时也会使用类似于人类的“儿语”方式，即调高音调、扩大音调范围，并且这种变化不仅出现在与幼小的宝宝交流时，也出现在与接近“学步”阶段的宝宝交流时。
1.D细节理解题。根据“Their speech includes higher pitches and a wider pitch range.They use shorter sentences and repeat words more often."可知，她们的语言包括更高的音高和更宽的音高范围。她们使用较短的句子，并且更频繁地重复词语。故选D。
2.D图示理解题。根据“dolphin mothers had a wider range off requencies of the sound—the maximum frequencies were higher and the lowest frequencies were lower"可知，当海豚和幼崽在一起时，海豚妈妈发出的声音频率范围更广——最高频率更高，最低频率更低。结合文中图表1,D选项符合最高频率高于图表1的最高值，最低频率低于图表1中的最低值。故选D。
3.A词义猜测题。根据“but with the children who are still learning to speak.As a result,our children are able to talk”可知，我们人类会和还在学习说“儿语”话的孩子们说“儿语”是为了孩子能够说话，所以海豚的“儿语”也是为了帮助幼崽学习发声说话，因此“phonate”表示发声。故选A。
4.D写作意图题。文章的最后一段说到关于海豚的儿语的研究提醒我们该语言在人类中的重要性。每当我们和幼儿交谈时，我们如何说话可能和我们说什么一样重要。由此可知作者想让人们注意与孩子说话的方式，故选D,
