Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.
So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don’t we use them for collecting energy?
The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?
The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.
Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.
We just can’t wait to see more of these roads all over the world in the near future.
The first paragraph serves as a(n)______.

A．argument

B．comment

C．explanation

D．background

When some animals are on the solar road, what will the road do?

A．Guide them to a safer place.	B．Remind drivers to drive slowly.
C．Frighten them away from the road.	D．Advise drivers to choose another way.

From the text, we can know that the Solar Road Panels can______.

A．provide heat for drivers in winter

B．guide drivers who get lost on the highway

C．melt snow and ice soon in winter

D．help drivers see the road clearly in the sun

Mom noticed that something was wrong when I started getting so thirsty, I’d have a lot to drink before bed, which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I’d drunk the entire container! My mom call my doctor. I then had a few blood tests, and the results were certain ------ I had diabetes, which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood-sugar level.
My eating habits had to change in a big way. With diabetes, I can’t eat a lot of sugar or carbohydrates. I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin before the meals to help my body process the food. Also, I test my blood-sugar level often. I’m always trying to keep my blood sugar at a healthy level. The level can drop when I exercise, but that doesn’t keep me out of gym class or off the basketball court ------ I just keep some juice boxes around to boost my blood sugar if I need to.
It’s a lot of work ------ and not a lot of fun ------ to keep track of everything, but I’ve gotten used to my new habits. I was a little scared at first because I wasn’t sure how my life would change. Once I knew what I needed to do, though, it wasn’t a big deal. My life is different now from what it was before, but it has become completely regular to me.

Sons who have fond childhood memories of their fathers are more likely to be emotionally stable（稳定的） in the face of day-to-day stresses, according to psychologists（心理学家） who studied hundreds of adults of all ages.
“As our study shows, fathers do play a unique（独特的） and important role in the mental health of their children much later in life,” Psychology professor Melanie Mallers of California State University said.
For this study, 912 adult men and women between the ages of 25 and 74 completed short daily telephone interviews about that day’s experiences over an eight-day period. The interviews focused on the participants’ psychological and emotional distress (i.e., whether they were nervous, sad, etc.) and if they had experienced any stressful events that day.
The participants were also required to answer questions such as, “How would you rate your relationship with your mother during the years when you were growing up?” and “How much time and attention did your mother give you when you needed it?” The same questions were asked about fathers.
People who reported they had a good mother-child relationship reported three percent less psychological distress（忧虑） compared to those who reported a poor relationship, according to Mallers.
Men who reported having a good relationship with their father during childhood were more likely to be less emotional when reacting to stressful events in their current daily lives than those who had a poor relationship, according to her findings.
Also, the quality of mother and father relationships was significantly associated（有关） with how many stressful events the participants faced on a daily basis. In other words, if they had a poor childhood relationship with both parents, they reported more stressful incidents over the eight-day study when compared to those who had a good relationship with their parents.
Mallers theorized why healthy or unhealthy relationships may have an effect on how people handle stress as adults. “Perhaps having caring parents equips children with the experiences and skills necessary to more successfully navigate（导航） their relationships with other people throughout childhood and into adulthood.” She said.
What can we know about the recent study from the passage?
A It was led by Melanie Mallers.
B 912 adults who were over twenty-five joined in it.
C It lasted as long as eight days.
D It was funded just by California State University.
Which of the following may the participants be asked about in telephone interviews?
A Their physical condition. B Their parenting（育儿） skills.
C Their emotional distress and stressful events.
D Their childhood relationships with teachers.
Which of the following statements is TRUE?
A Many people with good parent-child relationships still can’t keep emotionally stable in stressful incidents.
B Men with a good mother-child relationship were more likely to be emotionally stable when reacting to stressful events.
C Women were better at getting along with their parents than men when they were young.
D People with good childhood relationships with parents suffered（遭受） fewer stressful incidents.
What can be concluded from the findings of the study?
A Childhood memories of parents have a lasting effect on one’s ability to handle stress.
B Adults with good childhood relationships with parents will live happily and successfully.
C The mother-child relationship is more important than the father-child relationship.
D The quality of parent-child relationships determines（决定） how people handle stress as adults.

I read a letter of a mother of a gifted child to an expert with gifted children stating that her son was always complaining that he doesn’t like his teacher for she talks in baby language and she lets them sing baby songs. Having an insufficient（不足够的） understanding of being different from their normally developing classmates, gifted children may find themselves wanting to learn more than being boxed with other kids of their age. They want to quench（解渴） their thirst for knowledge. However, in the process, they tend to develop negative（负面的） thoughts about school and teachers. Thus, they tend to exhibit behavioral problems.
Behavioral problems of gifted children could be mainly correlated（相关的） to their asynchronous（不同步的） development. This development means that the child has uneven（不均衡的） development in their mind, body and emotions. To explain further, a gifted child may live in different ages at once. He may show high intellectual（智力的） capabilities at some point but the time his emotions rule, he would go back to his true age going through tantrums（脾气发作） and endless sobbing（哭泣）. He maybe find it happy playing with kids his age but the next day, he would be bored with that and he would find conversing with older kids to be more challenging.
Because of high intellectual level, a gifted child often acts differently in his own classroom. He has the thinking of being above from the rest of his classmates when it comes to grades, academic awards and school recognitions. In classroom discussions, the child may be very cooperative（合作的） having advanced knowledge in the lessons but it is mostly that he will suffer from boredom as he is not challenged by the lessons and he would feel no improvement with them.
Which of the following best explains the asynchronous development?
A A child has good development both in mind and body.
B A child cannot get along well with his classmates.
C A child is intellectually developed but not equal with emotionally.
D A child doesn’t feel happy with his school and teachers.
What is most likely to be talked about in the paragraph following the passage?
A How a gifted child gets along with his classmates.
B How to get a gifted child involved（被卷入） in a classroom discussion.
C What can arouse（激发） a gifted child’s interest.
D How a teacher should handle a gifted child in class.
We can infer from the passage that ______.
A we needn’t pay special attention to gifted children
B a gifted child is well above others in every way
C it’s best to teach a gifted child separately
D teaching a gifted child can be challenging
