【題目】 Have you ever made a mistake while trying to print from a computer? That paper probably went right into the recycling bin. From there, it is taken to a waste-handling plant to be eventually broken down and remade. But what if you could simply erase your mistake and reuse that paper? It may become available, thanks to a new technology.
It's a new type of rewritable paper that can be used more than 100 times. Words and pictures remain visible on it for at least half a year. This is nearly the first rewritable paper. But the marks on those earlier versions tended to fade away in less than three months.
Luzhuo Chen led the group that made the new rewritable paper. His team was inspired by pens that contain erasable ink. That ink disappears when heated. To make its new rewritable paper, Chen's group switched the ink from the pen to the paper. They covered one side of regular paper with the ink used in those erasable pens. Using a heated pen or printer, they can now write or print on this paper. That warmth makes the ink disappear.
This is the opposite of how writing usually works, where ink is applied to paper. With the new system, the spots where you write become white instead of colored because that heat makes the ink covering the white paper disappear.
Qiang Zhao has a creative mind behind another type of rewritable paper. He thinks Chen's paper is simple and doesn't cost much to make, so it should be easy and fairly inexpensive to produce. However, the paper will need a lot of ink. In large doses(劑量),chemicals in the ink can be bad for the environment and people's health. Zhao would like scientists to develop a safer ink. Still, he thinks this paper will have wide applications.
【1】Why does the author raise the questions in the first paragraph?
A.To prove the necessity of recycling paper.
B.To introduce the importance of rewritable paper.
C.To draw readers attention to the new technology.
D.To show the development of paper-making technology.
【2】What's the advantage of the new rewritable paper over earlier versions?
A.It can be reused for a lot more times.
B.The costs of producing it are much lower.
C.It can be produced in a much easier way.
D.The contents on it can be more long-lasting.
【3】Which of the following reflects Qiang Zhao's opinion on Chen's paper?
A.It still needs improving.B.It's somewhat impractical.
C.It does no harm to its users.D.It's worth promoting right away.
【4】What can we know about Luzhuo Chen's new paper from the text?
A.It shows colored words or pictures.
B.It doesn't require ink to write on it.
C.It will replace ordinary writing paper soon.
D.It has no requirement on the writing tool.
【答案】
【1】C
【2】D
【3】A
【4】B
【解析】
這是一篇說明文。文章講述了,打印犯錯,浪費紙張很可惜,但現(xiàn)在有了一項新技術——可重寫紙——能讓廢紙重新被利用;文章介紹了發(fā)明可重寫紙的過程、它的優(yōu)點和可能存在的問題。
【1】推理判斷題。由第一段的兩個問題“Have you ever made a mistake while trying to print from a computer?”(你用電腦打印時犯過錯誤嗎?)和“But what if you could simply erase your mistake and reuse that paper?”(但如果你能簡單地抹去你的錯誤并重新使用那張紙呢?)可以推斷出,如果讀者發(fā)現(xiàn)打印出錯還可以重新使用打印錯的那張紙的話,讀者的興趣和注意力就會集中到可重寫紙這項技術上。因此作者提出這些問題是為了吸引讀者關注新技術。故選C項。
【2】細節(jié)理解題。由題干關鍵詞the new rewritable paper可將答案定位于第二段。由第二段的前兩句“It's a new type of rewritable paper that can be used more than 100 times. Words and pictures remain visible on it for at least half a year.”和最后一句“But the marks on those earlier versions tended to fade away in less than three months.”可知,新型的可重寫紙,可以使用100多次,文字和圖片至少半年內(nèi)保持可見,但這些早期版本上的印記往往在不到三個月的時間里就消失了,所以新型的可重寫紙上的內(nèi)容能保留更長時間。故選D項。
【3】推理判斷題。由題干關鍵詞Qiang Zhao's opinion on Chen's paper可將答案定位在最后一段。由最后一段句子“However, the paper will need a lot of ink. In large doses(劑量),chemicals in the ink can be bad for the environment and people's health. Zhao would like scientists to develop a safer ink.”可知,這張紙需要很多墨水,大劑量使用時,墨水中的化學物質(zhì)會對環(huán)境和人體健康有害,趙希望科學家們開發(fā)出一種更安全的墨水,說明可復寫紙還需提升。故選A項。
【4】推理判斷題。由題干關鍵詞Luzhuo Chen's new paper可將答案定位于三四兩段。由第三段的句子“They covered one side of regular paper with the ink used in those erasable pens. Using a heated pen or printer, they can now write or print on this paper.”和第四段的句子“This is the opposite of how writing usually works, where ink is applied to paper. With the new system, the spots where you write become white instead of colored because that heat makes the ink covering the white paper disappear.”可知,他們用可擦筆上的墨水蓋住普通紙的一面,使用加熱筆或打印機可以在這張紙上書寫或打印,這與書寫通常的工作方式相反,即在紙上涂墨水,在新系統(tǒng)中,你書寫的地方會變成白色而不是有色,因為高溫會使覆蓋在白紙上的墨水消失,說明Luzhuo Chen的新紙是不需要墨水的。故選B項。
推理判斷題不僅要求考生讀懂文章中的每個句子的意思還要推理它們之間的關系,結合自己的生活常識和經(jīng)驗,再通過邏輯推理和判斷,理解文章的言外之意,從而揭示文章的深層涵義。推理判斷題的答案不可能在文章中直接找到,因此推理時我們務必要忠于原文,在文章中尋找并確定可推論的依據(jù),即:已知部分-推論的前提,從中推測出未知部分-推理的結論,切忌妄加評論,把自己的觀點當成作者的觀點。如在第3小題中,最后一段中的句子“However, the paper will need a lot of ink. In large doses(劑量),chemicals in the ink can be bad for the environment and people's health. Zhao would like scientists to develop a safer ink.”,是已知部分,通過結合原文進行合理地邏輯判斷,可以得出可復寫紙還需提升。故選A項。

【題目】 If you were like most kids, your mother must have told you there were three no-no’s when it came to your fingers: Don’t put them in an electrical outlet, don’t stick them up your nose (at least not in public), and don’t use them when you are counting. 【1】 But experts in education and cognition now believe that using your fingers to do math is not only a perfectly good idea but may even help children become superior students.
It certainly makes sense. When children count on their fingers, they take an abstract concept — mathematics — and translate it into the most basic and visual form 【2】. Even when we aren’t actually counting on figures, they still can help us on math problems.
【3】 It activates when we respond to heat, pressure, pain, or the use of a given finger.
Studying brain scans, researchers discovered that when students aged 8 to 13 work on subtraction (減法 ) equations, this region “l(fā)ights up” on the scans, even if the students aren’t using their fingers. The more complex the problem is, the more activities are detected.
The connection between finger use and math ability has been proved on old-fashioned math tests as well. With their eyes closed, first graders were asked to identify which of their fingers a researcher was touching. 【4】. When college students were given the same quiz, the highest scores once again performed best on calculation tests.
So what does all this mean? For one thing, parents and teachers shouldn’t discourage children from counting on their fingers. 【5】. Memorizing the multiplication tables may help, but it is not the best option. “I would like to see interesting and creative representations of ideas.” says Jo Boaler, a professor of math education.
Recently, a series of activities have been designed to strengthen students’ perception of their fingers. Maybe in the near future, there will be only two no-no’s regarding the use of fingers.
A.There is a section of the brain, called the somatosensory finger area.
B.Researchers also stress that students simply learn better using visual tools.
C.The first two laws of fingers are as true as ever.
D.That may sound simplistic, but the researchers offer an interesting explanation.
E.Researchers found those scoring highest on the finger-ID questions scored higher on a math test.
F.Researchers are unimpressed by those students who finish quickly as well.
G.In fact, experts believe the brain is built to “see” any process with our fingers.

Researchers Are Racing to Make a Coronavirus Vaccine. Will It Help?
In the early days of January, as cases of a strange, pneumonia-like illness 【1】 (report) in China, researchers at the National Institutes of Health readied themselves to hunt 【2】 a vaccine to prevent the new disease.
Scientists in Australia are also working on vaccine candidates 【3】 (stop) the spread of the disease. Historically, vaccines have been one of the greatest public health 【4】(tool) to prevent disease. But even as new technology, advancements in genomics(基因組學) and improved global coordination have allowed researchers to move at unprecedented speed, vaccine 【5】(develop) remains an expensive and risky process.

In the best case, it takes at least a year — and most likely 【7】(long) — for any vaccine to become available to the public.
With each new outbreak, scientists 【8】 (typical) have to start from scratch. After the SARS outbreak in 2003, 【9】 took researchers about 20 months from the release of the viral genome(基因組) to get a vaccine ready for human trials. By the time an epidemic 【10】 (cause) by the Zika virus occurred in 2015, researchers brought the timeline down to six months. Now, they hope the joint efforts will cut that time in half.
