New Haven.Just this morning, my 11-year-old son shared with me a “really sad dream”. Keep in mind that this is from a boy who watches very little war news, who rarely hears his parents talk of war, who has no relatives personally involved in the war. The dream went something like this:All the fifth-grade boys from his school were soldiers in the war. Dylan and my son were on the Ukrainian side. Alex and others were fighting together with the Russians. These and other friends were found on both sides of the conflict, but none of them wanted to kill each other. They were actually trying to help and protect one another. Then a Russian soldier who was not someone the boys knew attacked Dylan. Alex and Andrew tried to warn Dylan and stop the attack, but it was too late. Dylan died. And it was very sad.Besides the emotional power of the distant war expressing itself in my son’s life, what impressed me about his dream was that there were good people fighting on both sides. Is that an 11-year-old’s myth, or could it really be true? I affirmed (肯定) his concern for all the people directly involved in the war, all of which was pretty much in line with what the experts advise.My son doesn’t get much news exposure from television, vastly preferring kid entertainment when he has a choice. And that’s. just as well. In fact, limiting children’s media exposure to war is one of the key suggestions the experts make.However, there are questions and concerns. For weeks, my son has been praying daily that we will not go to war. Now he prays the war will end soon, and that people will not get hurt or killed. A few days ago, he voiced the almost casual question, “Will the war come to Oklahoma?” I answere d no, and we agreed that we are fortunate to be far from the war. And yet, I think my son already understands that disaster —including the intentional horror of terrorism — can happen anywhere, like New York, Washington or even Oklahoma City. But still, t hat’s hardly the same as living with a daily personal fear or expectation of war reaching your home.Tonight I kissed my boy goodnight and put him to bed, as again he prayed that God would help the war to end soon. I wonder how many more nights he will have to say that prayer…4．Which of the following word can best describe the war in the boy’s dream? A．Expected. B．Natural.C．Unrealistic. D．Boring.5．What do the experts advise people to do about the war?A．Keep children from TV viewing.B．Stop thinking too much about the war.C．Show concern for whoever suffers from the war.D．Encourage children to be concerned about the war.6．How does the author feel about the war?A．Uncertain when it will come to an end.B．Fearful that it will come to Oklahoma.C．Worried that it will cause more deaths.D．Fortunate that it hasn’t affected her family.7．What is the purpose of the text?A．To show how the war affects a kid.B．To show what the war is like in a kid’s dream.C．To show what a kid should do to stop the war.D．To show what attitude a kid should take to the war.With the recent discussion about the health benefits of fish oil and other wellness plans, it can make you feel less worried to know that one thing never changes: Exercise is good for your health. Any movement, even walking, brings about a host of cardiovascular(心血管的)effects that can help you live longer, feel better, and not run out of breath when chasing children or small animals.The question of how much exercise is best, though, is open to discussion. The answer often depends on your goals. For heart health, sessions four to five times weekly might be perfect. For mental health? As The Independent reports, scientists believe there’s a pretty specific prescription(处方): Exercising for 45 minutes three to five times a week.Researchers at Yale University and the University of Oxford made the study. They examined 1.2 million subjects(实验对象)who filled out the Behavioral Risk Factor Surveillance Survey at two-year intervals(间隔时间)between 2011 and 2015.Subjects who didn’t exercise at all had an average of three-and-a-half days per monthwhen they felt mentally unwell — stressed, depressed, or suffering from emotional problems — while those who exercised regularly reported an average of just two days.The study found that having three to five 45-minute sessions of exercise a week was best for reducing the reported problems of feeling stressed or depressed. Exercising for longer periods — some subjects reported more than 90 minutes in the gym — was connected with a drop-off in mental health benefits. Subjects who spent three hours at a time exercising actually reported an increase in depressive symptoms(症状).Researchers also found that the kind of exercise undertaken made a difference. While all kinds of exercise helped, people who took part in team sports promoting social communication and gym classes like cycling described greater self-satisfaction with mental health.Because the study included self-reported outcomes and exercise wasn’t monitored, it’s possible that the subjects could have misread the amount of exercise performed. The study, however, makes a convincing case for a popular opinion: If exercise were a pill, doctors everywhere would be prescribing it.8．The perfect amount of exercise for a person is usually decided by ________.A．his exercise routine B．his physical conditionC．what sports he prefers D．what he expects to improve9．What do the numbers in paragraphs 4 and 5 show?A．The health benefits of exercise.B．People’s response to hard exercise.C．How exercise influences one’s mental health.D．Why positive attitudes promote one’s exercise.10．Which of the following sports may bring people more pleasure?A．Tai chi. B．V olleyball. C．Climbing. D．Diving.11．What may be the reason for the disadvantage of the study?A．Too few participants.B．Its researchers’ personal interests.C．The subjects’ personal judgments.D．Its failure to consider doctors’ suggestions.There's more evidence that what's good for your heart is good for your head. A new studyshows that people who run, swim or do other moderate intensity （中等强度）exercise have brains that look, on average, 10 years younger than the brains of couch potatoes.“Our study showed that for old er people, getting moderate intensity exercise may be protective, helping them keep their brains work better," said Dr. Clinton Wright of the University of Miami, who led the study. But it's not necessarily easy. Walking, golf, bowling and yoga don't count, and people need to start before they begin showing memory loss, Wright' s team reported in the journal Neurology.The study of nearly 900 people who exercise regularly showed that 90 percent fell into the low-intensity group. These people are part of a larger group taking part in a bigger study called Northern Manhattan Study. They were asked how long and how often they exercised during the past two weeks. Five years later, they were tested for memory and thinking skills and got a brain MRI. Seven years after that, they took the memory and thinking tests again. The 10 percent who said they took part in moderate intensity exercise scored better on the tests. These included running, climbing, swimming, riding bicycles and so on.“We found that those with mod erate intensity activity had higher scores and slower decline than inactive people when comparing the results," the study team wrote.Many studies have shown that exercise may not prevent Alzheimer's disease but may delay it. The findings fit in with a study that found two years of exercising, eating healthier food and brain training can promote people's memory function.12．What's true about the study?A．Most people surveyed took low-intensity exercise.B．Only 900 people took part in the bigger study.C．High-intensity exercise is better.D．Ten people scored best on the tests.13．How did the study team come to the conclusion?A．By observing people exercise. B．By using examples.C．By making a comparison. D．By doing a brain MRI.14．What do we know from the last paragraph?A．Exercise will definitely strengthen people's memory.B．Alzheimer's disease may be held back by moderate intensity exercise.C．Exercise can put off the beginning of memory decline.D．The findings fit in with the study of healthy food.15．What's the best title for this passage?A．How to keep health.B．Ways to make your brain work better.C．To exercise or not.D．Moderate intensity exercises keeps your brain younger.二、七选五16．Camping is a great way to enjoy nature. You can breathe fresh air, cook over a campfire and sleep under the stars. However, camping also means dealing with bugs, bad weather and few, if any, toilets. ①_______ But there is a way to enjoy the natural world without giving up the comforts at home. It’s called glamping, and interest in it has been growing since 2007!Glamping, a combination of the words glamorous (有魅力的) and camping, is a fairly new word. ②_______Since around 600 B．C．Nomadic Mongolians have enjoyed the benefits of glamping. Their tents were so comfortable that they inspired the design of modern glamping tents!There are many reasons why you should consider glamping for your next vacation. One of them is that glamping gives you access to some wonderful places. ③_______ Nowadays, glamping can be less expensive than staying in a hotel. But you can still enjoy the modern comforts of a hotel!using much plastic. So, there is less waste, and the area stays beautiful.No matter what kind of experience you’re looking for, a glampsite exists for you. From Three Camel Lodge in Mongolia to Clayoquot Wilderness Resort in Canada, adventure is waiting for you. Sites can include a spa, a swimming pool and dinner under the stars. Activities can include exploring on horseback or camel and sightings of elephants, mountain sheep or tigers.A．You don’t have to give up beauty for comfort!B．These are all the benefits and problems camping can bring.C．These troubles can discourage people from ever trying camping.D．But it describes an activity that people have been doing for ages.E．Another reason to go glamping is that it’s good fo r the environment.F．A wide variety of glamping experiences are available all over the world.G．You can also lend a hand with protecting the environments of these places.三、完形填空（15空）Noah had never once been on his family's back porch(门廊)。
