21、 Two years ago, my 11-year-old son sat me down for a talk.“Mom, it's time," he said.“Hear me out: It's time we got actual TV. And you need an iPhone.”
This funny conversation two years ago marked a shift in our relationship. Perhaps for the first time, I began to really listen to my son's opinion about our home technology. Since his reasoning was sound and his suggestions within budget, I took his advice and was pleasantly surprised with the results.
I'd known for a while that my son understands technology better than I do. On airplanes, he grabbed my phone to put it in airplane mode. He wired the speakers in our house. After something was stolen from our front yard, he picked out, set up, and now monitors our security camera. When my computer died, I took him shopping with me.
As a teenager now, he has a busy social life, with skateboarding, basketball, and online gaming with his friends. I see our time together waning and our shared interests shrinking. That's why I jumped at the chance when a friend mentioned writing technology reviews. I'm a writer, but I'd need a partner who has more tech knowledge than me. When I presented the idea to my teen, he immediately accepted.
It's changed our relationship in surprising ways. Where he used to get annoyed quickly at my technical ignorance, he's learned to be more patient and explain things to me in a way that I can convey to an unknowing audience. The parent-child dynamic is not only changed; it's even slightly reversed(颠倒). He's leading me. I'm asking him for help and advice.
My son has risen to the occasion. He's taking it seriously, and to watch him mature in this way is an honor. As someone who's not much of a reader, he now searches instruction manuals. Without any prompting, he's even emailed and called-----yes, made an actual phone call to customer service or tech support when sample products weren't working as expected.
I never imagined being a tech reviewer, but it's proved to be a valuable way to learn from, work with, and enjoy time with my teen.
【1】What did the writer think of her son's advice?
A．It sounded sensible.
B．It was brainless.
C．It was childish.
D．It was useless
【2】What does the writer intend to do in Paragraph3?
A．Introduce the busy life her son is living.
B．Give examples of her son's interest in technology.
C．Prove her son's better command of technology.
D．Show her pride in her son's competence.
【3】What does the underlined word “waning” in Paragraph 4 mean?
A．Worsening.
B．Decreasing.
C．Freezing.
D．Hardening.
【4】What makes the writer feel honored?
A．Her son's patience to explain technical things.
B．Her son's control of the parent-child dynamic.
C．Her son's rich knowledge of technical terms.
D．Her son's careful attitude towards the work.
22、The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.
Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.
There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finallyuncorked, their power to destroy is set free.”
There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.
Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.
Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.
Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.
【1】What’s the function of the example in Paragraph 2?
A. It reflects that people are concerning about the spread of Ebola.
B. It shows the bad effect caused by sharing a story.
C. It proves not sharing a story can cause trouble.
D. It concludes that one should share a story at a proper time.
【2】One of the reasons why people are unwilling to share experiences is that _______.
A. story-sharing highlights the importance of hard work
B. people are used to exposing their weaknesses
C. people sometimes have no courage to share their stories
D. some stories make themselves feel uneasy
【3】Which is close in meaning to the underlined word “uncorked” in Paragraph 3?
A. freed B. broken C. unfolded D. untouched
【4】The writer aims to convince us to _______.
A. be open to people close to you by sharing some secrets
B. share stories appropriately for the good of others and ourselves
C. remove the dangers that can be caused by untold stories
D. realize the importance of being honest when making friends
23、 Scientists have designed “transparent wood” that could replace conventional glass in windows. The innovation was developed using wood from the balsa tree, which is native to South and Central America, and claims to be five times more thermally efficient than glass.
The team treated balsa wood in an oxidizing bath (氧化池) that bleaches (漂白) it of nearly all visibility and then poured it into a synthetic polymer (合成物) called polyvinyl alcohol (PVA 聚乙烯醇), creating a product that is virtually transparent.
Unlike traditional glass, the transparent wood can bear much stronger impacts and will bend or separate when damaged, instead of being destroyed into tiny pieces.
The transparent wood was created by teams at the University of Maryland and University of Colorado, which set out to find a greener alternative to conventional glass—a production that creates 25,000 tons in emissions each year.
Along with contributing to greenhouse gases, glass contributes to a loss of energy.
“Residential building windows in particular account for 10-25% of the heat loss due to their poor thermal (保热的) management capability,” the team wrote in the study.
“Exploring energy efficient window materials is thus highly desirable to address heating costs, energy shortages, and the global impact of climate change associated with increased carbon emissions.”
The team notes that the bonding between PVA and cellulose (纤维素) in the wood, creates a tightly packed structure that allows for more thermal protection and makes it more durable and lighter than glass.
“Switching to transparent wood could prove to be cost efficient as well,” researchers shared in a statement.
“It is approximately five times more thermally efficient than glass, cutting energy costs.”
“It is made from a sustainable, renewable resource with low carbon emissions. It’s also compatible (兼容的；可共存的) with existing industrial processing equipment, making the transition (过渡) into manufacturing an easy process.”
【1】How many key steps are to take to make balsa wood transparent based on the passage?
A．One.
B．Two.
C．Three.
D．Four.
【2】Among the items listed below, which ones are transparent wood’s advantages over conventional glass?
① being more thermally efficient
② bearing much stronger impacts
③ breaking into tiny pieces when damaged
④ cutting energy costs
⑤ contributing to a loss of energy
⑥ being more durable and lighter
A．①②③④⑥
B．①②④⑤⑥
C．①②④⑥
D．①②④⑤
【3】Which of the following is NOT TRUE of the research team?
A．They developed the transparent wood from the balsa tree native to South and Central America
B．They set out to find a greener alternative to conventional glass because glass contributes to loss of energy.
C．They claimed the transparent wood was five times more thermally efficient than glass.
D．They concluded the process of producing the transparent wood is more difficult than that of producing glass.
【4】The passage is mainly about ________.
A．a new technology of replacing transparent wood
B．a production of a new type of building material
C．an innovation (改革；创新) of new residential (适于住宅的) building glass
D．an invention of a new energy efficient window material
