Listen carefully.Don't answer too quickly.At least，don't say"yes" too soon.A friend might ask ，"Want to take a hike？" You should say ，"Where？"If he replies "The entire Appalachian Trail（阿巴拉契亞國(guó)家步道）"，take warning.Here's why.
The trail is one of the longest marked footpaths in the world.It starts at Springer Mountain，Georgia.It winds along the top of the mountains.It goes through 14 states.It ends at Mount Katahdin ，Maine.As the crow（烏鴉） flies ，this is about 2，200 miles.But when walked ，the trail is 2 ，600 miles.If you walk nonstop ，it takes about six months to walk through the trail.
Most hikers begin from Springer Mountain.They start around April 1.This is why.The snow has probably melted in the south.But there may still be snow in the north.By the time they reach Maine ，the snow will have been long gone.What's the chance of making it nonstop？Here is the data.About 1 ，500 people try it each year.About 300 people make jye.ai.It is a great challenge indeed.
Careful planning is necessary.There are problems to solve.The biggest one is the weight on one's back.Too many hikers start out with too much.Wise ones don't carry food.They send packages to post offices along the way.There are no campfires allowed.Some shelters are near the path.But the trail is crowded.It is hard to find space.A perfect tent is necessary.And it rains a lot.Great rain gear is needed.It should be light.
Benton MacKaye founded the trail.The first section of the trail was opened in 1923.It is cared for by volunteers in each state.Do you plan to go？Read lots of books by people who've done it.

1．When your alarm clock rings and you drag yourself out of bed，you probably wonder：Why on earth does school have to start so early？
Fortunately，there is a new law to back you up — or better still，science.
A law in California，passed on Oct 13，requires that public middle schools begin classes no earlier than 8：00 am and that high schools start no earlier than 8：30 am.The law will go into effect by November 1，2022.
Starting school at 8：00 or 8：30 in the morning may not sound like too big of a change，but it could mean one more hour of sleep for students who used to start school at 7：30 or even earlier.
"The effect of that one hour is something they will be feeling as 40-year-old adults，" Sumit Bhargava，a sleep expert at Stanford University，told The New York Times.He said that not having enough sleep can affect students' mental health and increase the risk of being overweight and diabetes （糖尿?。?
In the short run，students' school performances should improve almost immediately.Kyla Wahlstrom，a researcher at the University of Minnesota's College of Education，found that students who have enough sleep are alert in class and get much more satisfying grades.
Some might say that asking students to go to bed earlier could have been a much easier solution than changing the school timetable across an entire state.But according to the American Academy of Sleep Medicine，teenagers go through biological changes when they enter puberty （青春期），which makes it difficult for them to fall asleep before 11：00 pm.So when school starts at 8：00 or earlier，they can hardly get the ideal 8.5 - 9.5 hours of sleep that experts suggest they need to do their best in the daytime.
This is why when the new law came out，its author，Anthony Portantino，said， "Generations of children will come to appreciate this historic day and our governor for taking action."
（1）Which of the following is TRUE about the law？
A．The law has not been put into practice yet.
B．The law will be passed by November 1，2022.
C．The law is made by a university in California.
D．The law requires schools to start later than 8：30 am.
（2）What can we learn from Bhargava's words？
A．The new law is of lasting benefit to students.
B．Lack of sleep affects adults more than children.
C．The amount of sleep people need changes with age.
D．Enough sleep makes sure that students are mentally healthy.
（3）What does the underlined word "alert" in Paragraph 6 probably mean？
A．Friendly.
B．Honest.
C．Calm.
D．Sharp.
（4）What's the text mainly about？
A．Lack of sleep could lead to health problems.
B．California is pushing back school start times.
C．A law to start the school day later takes effect.
D．Teenagers' biological changes affect their sleep patterns.發(fā)布：2025/1/1 16:0:1組卷：7引用：4難度：0.5 -
2．Modem life is full of things that can influence your ability to be sensitive and responsive to your child.These include extra work，lack of sleep，and things like mobile devices.Some experts are concerned about the effects that distracted（分心）parenting may have on emotional bonding and children's language development，social interaction，and safety.
If parents are inconsistently available，kids can get distressed and feel hurt，rejected，or ignored.They may have more emotional outbursts and feel alone.They may even stop trying to compete for their parent's attention and start to lose emotional connections to their parents.
"There are times when kids really do need your attention and want your recognition explains Cmic，a psychologist. "Parents need to communicate that their kids are valuable and important，and children need to know that parents care what they're doing，" he says.
It can be tough to respond with sensitivity during tantrums，arguments，or other challenging times with your kids. "If parents respond by being bad-tempered or aggressive themselves，children can copy that behavior，and a negative cycle then continues to upgrade，" explains Dr.Carol Metzler，who studies parenting at the Oregon Research Institute.
According to Cmic，kids start to regulate their own emotions and behavior around age three.Up until then，they depend more on you to help them regulate their emotions，whether to calm them or help get them excited. "They're watching you to see how you do it and listening to how you talk to them about it，" he explains. ^Parents need to be good self-regulators.You're not only trying to regulate your own emotions in the moment，but helping your child learn to manage their emotions and behavior."
As kids become better at managing their feelings and behavior，it's important to help them develop coping skills，like active problem solving.Such skills can help them feel confident in handling what comes their way.
"When parents engage positively with their children，teaching them the behaviors and skills that they need to cope with the world，children learn to follow rules and regulate their own feelings." Metzler says.

3．According to a new study in the online PLOS ONE，people make their decisions to trust others largely based on their faces.Your appearance can do a lot for you，especially if you are in the financial industry.The more trustworthy you look，the more likely people will buy what you're selling.
Researchers from Britain's University of Warwick Business School，University College London，and Dartmouth College，US，did a number of experiments.The research team used computer software to make 40 faces，from the least to the most trustworthy-looking.The study said that the difference between a trustworthy face and one that isn't as trustworthy comes from features that look slightly （稍微） angry or slightly happy，even when the face is at rest.However，a slightly happy face is more likely to be trusted.
Researchers gave participants some money and asked them which face they trusted to invest （投資） the money for jye.aim.Then researchers gave some good and bad information about the people with these faces，and asked the participants again whom they trusted.The results showed that even if they got different information，the participants didn't change their choices.They were still more likely to invest their money with the more trustworthy-looking faces.
Chris Olivola，one of the study's authors，said in the University of Warwick's press release： "It seems we are still willing to go with our feelings about whether we think someone looks like that we can trust jye.aim.The desire to judge strangers by their faces is hard to resist."
（1）According to the study，which of the following faces is most likely to be trusted？
