Did you know that horses talk? Well, they do, and you can lean to understand “horse talk” if you pay close attention to the horses you see.
When horses live in the wild, other animals try to eat them, so a lot of horse talk is about staying alive. Even now, when most horses live on farms, they watch for danger. For this reason, never walk behind a horse. If you surprise it, the horse might mistake you for a mountain lion or wolf and give a dangerous kick.
By watching the ears of a horse, you can get clues to what it's hearing. A horse can tum each ear in a different direction. For a wild horse, this trick is important for survival. The horse can hear something sneaking up behind it while also checking out a threatening noise in front. When a horse lets its ears down, it's feeling safe and relaxed. If horses becomeisolated, they neigh, or “whinny,” calling for company. They're saying, “Where are you? I'm over here!” If a horse snorts(哼) while holding its head high and staring at something, it's saying, “That looks dangerous. Get ready to run!” When two horses meet, they put their noses together and smell each other's breath. It's their way of asking, “Are you a friend?” Horses nicker,too. Nickering is a quiet sort of sound. This friendly noise means they're feeling secure and saying, “Clad to see you.”
In the wild, horses live in herds, with all members watching for danger. In a herd, only one horse is the leader, the “boss hoss”. The “boss hoss” is usually an older female. She watches for threats and teaches younger horses how to behave. However, others may want her job. When that happens, she pins her ears back against her head and may even bite or kick to get challengers to back off. She's using body language to say, “Hey, I'm in charge here!” All horses know that the one who makes others move is the leader. Horses relate to people that way, too.
Horses have a language of their own. Now you know a bit of what they might be saying.
4. What is the general idea of this passage?
A. Horses can talk with their owners.
B. You can know a bit of horses' language.
C. Horses can “talk” in their own way.
D. Other animals can also learn language.
5. What does the underlined word “isolated” in Paragraph 3 mean?
A. Lonely.
B. Glad.
C. Sad.
D. Frightened.
6. What will a horse do when he wants to know whether another horse is a friend?
A. He will let his ears down.
B. He and another horse will put their noses together and smell each other's breath.
C They both will hold their heads high and stare at something.
D. He will give another horse a dangerous kick.
7. How will the “boss hoss” deal with her challengers?
A. By warning or fighting.
B. By watching for threats.
C. By teaching younger horses how to behave.
D. By relating to people.
C
It is universally acknowledged that renewable energy sources such as solar, wind and hydropower are all much better for the climate than fossil fuels.It is true for wind and solar. However, the picture for hydropower is more complicated than we think.
A new study by the Environmental Defense Fund analyzed the climate impacts of 1,500 hydropower facilities across the globe. That accounts for about half of hydropower generation worldwide. The researchers looked at whether the facilities behave as a greenhouse gas sink or as a source. To figure this out, they looked into all the different components that help determine a hydropower facility's greenhouse gasemissions (排放).
“There are so many contributors to greenhouse gas emissions from hydropower — but essentially, the majority of greenhouse gas emissions arise from the reservoir (水库) itself, as vegetation and soils are submerged underwater in the dam thatis used for the hydropower generation.” said lissa Ocko, a senior climate scientist at the Environmental Defense Fund and co-author of the study. As the submerged vegetation breaks down, it releases greenhouse gases such as CO2.
“The larger the surface area of the reservoir, the more greenhouse gases are going to be given out from that reservoir. Also, the temperature plays a role as well how warm the reservoir is will affect how much greenhouse gases are produced and given out from the reservoir.” added Ocko.
Through their analysis, Ocko and her co-author Steven Hamburg, also with the Environmental Defense Fund, discovered that the climate impacts of hydropower cover a complete range. The good news is that some facilities perform just as well as wind and solar. But shockingly, more than 100 facilities are actually worse for the climate
than fossil fuels. The study is in the journalEnvironmentalScience and Technology.
This finding doesn't mean we should forget about hydropower. “But we just need to be careful to make sure that we have climate benefits. There are a lot of situations where hydropower can be equal to wind and solar. So it really depends on the specific facility." said Ocko.
8. How do scientists prove hydropower facilities' effect on the climate?
A. By making comparisons.
B. By conducting experiments.
C. By referring to previous studies.
D. By analyzing causes and effects.
9. What are the main sources of greenhouse gases from hydropower?
A. Vegetation and soils.
B. Heat and sunlight.
C. Pollutants in the reservoir.
D. Components of the generators.
10. What have Ocko and her co-author Steven Hamburg found?
A The surface area of a reservoir decides the climate.
B. Hydropower often influences the climate in all aspects.
C. Some facilities perform much better than wind and solar.
D. Fossil fuels are worse for the climate than over 100 facilities.
11. What is the text mainly about?
A. Scientists urge an end to hydropower.
B. Hydropower is not necessarily green.
C. Hydropower is worse than fossil fuels.
D. Renewable energy is a complicated issue.
D
It is not only praise or punishment that determines a child's level of confidence.There are some other important ways we shape our kids — particularly by giving instructions and commands in a negative or positive choice of words.For example, we can say to a child “Don't run into traffic！” or “Stay on the footpath close to me.” In using the latter, you will be helping your kids to think and act positively, and to feel competent in a wide range of situations, because they know what to do, and aren't scaring themselves with what not to do.
Actually, it is all in the way the human mind works.What we think, we automatically rehearse.For example, if someone offered you a million dollars not to think of a blue monkey for two minutes, you wouldn't be able to do it.When a child is told “Don't fall off the tree，” he will think of two things：“don't” and “fall off the tree”. That is, he will automatically create the picture of falling off the tree in his mind.A child who is vividly imagining falling off the
tree is much more likely to fall off.So it is far better to use “Hold on to the tree carefully.”
Clear, positive instructions help kids to understand the right way to do things.Kids do not always know how to be safe, or how to react to the warning of the danger in negative words.So parents should make their commands positive.“Sam, hold on firmly to the side of the boat” is much more useful than “Don't you dare to fall out of the boat？” or “How do you think I'll feel if you drown？” The changes are small but the difference is obvious.
Children learn how to guide and organize themselves from the way we guide them with our words, so it pays to be positive.
12. Positive choice of words helps kids to ________.
A. learn in different situations
B. do things carefully
C. build up their confidence
D. improve their imagination
13. What can we infer from Paragraph 2?
A. A child will act on what is instructed.
B. One can't help imagining what is heard.
C. A child will fall off the tree when told not to.
D. One won't think of a blue monkey when given money.
14. Which of the following commands helps kids to be safe?
A. How do you think I'll feel if you get hurt?
B. Don't play by the lake.
C. Don't you dare to walk through the red light?
D. Fasten your seat belt.
15. The main idea of the passage is that ________.
A. positive instructions guide kids
B. praise makes kids confident
C right instructions keep kids safe D. clear commands make kids different

阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

选项中有两项为多余选项Should you listen to music when you work? Some will say they love it, claiming that it improves their performance; others will say they cannotwork effectively with music playing in the background.____16____It just depends on what sort of work you’re doing.
In a recent study, we brought participants into our lab with a variety of tasks. They included an easy task—searching through word lists and crossing out words containing the letter “a” and a more difficult task—memorizing word pairs and recalling the partner to each word. Some participants completed all of the tasks in silence, whereas others completed the tasks with instrumental music that was either loud or soft, and either
simple or complex, the latter meaning music with more instrumental tracks.____17____
We found that participants who listened to simple music or no music performed about the same on the easy task.____18____Contrarily, participants performed worse on the more difficult task when they listened to any music, regardless of complexity or volume, compared to those who didn’t listen to any music.
____19____Not surprisingly, we typically need to use fewer of our mental resources when we perform easy tasks, whereas demanding tasks require more brainpower. However, because we might be less engaged during easier tasks, there’s a greater risk of drifting off to sleep. Music might give us the extra boost we need to get refreshed.____20____Listening to music can become overkill (过犹不及). So we have to strike a balance between the type of music and the type of task.
A. What should we make of these findings?
B. Several key findings emerged from our study.
C. However, difficult tasks already demand a lot of our mental resources.
D. Ourresearch has found that the effects of work may depend on our personalities.
E. We want to develop a more comprehensive framework that could be applied broader.
F. However, participants who listened to complex music performed best on the easy task.
G. Interestingly enough,our research has found that both of these perspectives can be true.

Now I’d like to telling you something about my part-time job, in it I work as a guide in a travel agency. This is the first time when I have earned money. I’ve realized what hard my parents work to support for the family. I was used to ask them for money, but now I’ll never waste money or learn to share worry with my parents. I’ve learnt how to get along well with other. What’s more, I have gained some social experience and I have learnt something can’t be learnt from textbooks. In the word, I had a wonderfully and valuable summer vacation.
