【題目】 Reducing plastic waste isn't easy because the cheap material is found in almost every household item. Now, a delicious and nutritious solution has come up to help reduce our dependence on this environmental hazard.

David Christian, the co-founder of Evoware, says the idea of creating the biodegradable (生物降解的) products came from concern at the country’s high pollution rate. Indonesia is home to four of the world's worst polluted rivers. Since single-use packaging is a large contributor to the problem, Evoware decided to deal with that first.

After investigating various materials, the company settled on seaweed. Unlike corn, commonly used for biodegradable containers, seaweed does not require resources like water or large amounts of space. Since Indonesian farmers already harvest more seaweed than they can sell, it's easy for the company to find the material.

Though they will not reveal their production process, Evoware says the seaweed packaging contains no chemicals and is safe to consume. The company has also invented single-use cups, which can break down 30 days after they're thrown away.

While replacing plastic with the seaweed products may seem appealing to most of us, it is a hard-sell in Indonesia. According to Christian, 'The awareness to reduce single-use plastic is still very low. This makes our bioplastic unnecessary.” Also a factor is the cost, which is higher than using plastic. Hopefully, Evoware will succeed in convincing Indonesians and people worldwide that switching to their products will be helpful to protecting our beautiful planet.

1What problem did Evoware decide to deal with first?

A.Ways to clean the four worst polluted rivers.

B.What nutritious materials for people to use.

C.How to deal with single-use packaging.

D.Means to contribute to the country's economy.

2Why did Evoware choose seaweed?

A.It didn't require much space and was easy to get.

B.It could be found everywhere in his country.

C.It was most commonly used for packaging.

D.It grew thickly in most of the polluted rivers.

3What can we infer from Christian's words?

A.Their seaweed products have won government support.

B.Sometimes it's hard to get people to reduce the use of plastics.

C.Their new products have received worldwide popularity.

D.The cost of making seaweed products will be lowered soon.

4What does the underlined word 'hard-sell' in Paragraph 5 refer to?

A.Something lasting long.B.Something hard to accept.

C.Something easy to get.D.Something commonly seen.

【解析】

這是一篇說明文。文章講述了因為塑料制品污染環(huán)境,科學家們研發(fā)了海草產(chǎn)品取代塑料制品。

1細節(jié)理解題。根據(jù)第二段的Since single-use packaging is a large contributor to the problem, Evoware decided to deal with that first.可知,因為一次性包裝袋是印尼河流污染的重要原因之一,于是Evoware決定從解決一次性包裝袋的問題開始。C. How to deal with single-use packaging.(如何解決一次性包裝袋)符合以上說法,故選C項。

2細節(jié)理解題。根據(jù)第三段的seaweed does not require resources like water or large amounts of space. Since Indonesian farmers already harvest more seaweed than they can sell, it's easy for the company to find the material.可知,Evoware選擇海草的原因是,海草對水和空間要求不大,而且印尼漁民收獲的海草賣不完,公司很容易就能找到這種材料。A. It didn't require much space and was easy to get.(它不需要很多空間而且容易獲得)符合以上說法,故選A項。

3推理判斷題。根據(jù)最后一段的The awareness to reduce single-use plastic is still very low. This makes our bioplastic unnecessary.可知,印尼人減少使用一次性塑料制品的意識還不夠,生物塑料對他們來說可有可無。故推測,有時候讓人們減少塑料的使用比較困難,因為他們在這方面沒有足夠的意識。B. Sometimes it's hard to get people to reduce the use of plastics.( 有時候讓人們減少塑料的使用比較困難)符合以上推測,故選B項。

4詞義猜測題。根據(jù)劃線部分所在句子While replacing plastic with the seaweed products may seem appealing to most of us, it is a hard-sell in Indonesia.可知,雖然使用海草產(chǎn)品代替塑料制品對我們來說很有吸引力,但在印尼卻是一個hard-sell。結(jié)合句意,尤其是whileappealing to可推測劃線部分的意思是“很難接受的東西”。B. Something hard to accept.(難以接受的東西)符合以上猜測,故選B項。

【題目】 The first study to examine generational differences in perfectionism over the past three decades reports that young people's desire to be flawless has sharply increased over the past thirty years. Today's college-age students are much more likely to have perfectionism than prior generations, according to the new report.

This study was recently published in the journal Psychological Bulletin. For this study, lead author Thomas Curran and co-author Andrew Hill, analyzed data from 41,641 college students in the United States, Canada, and the United Kingdom. They also used the Multidimensional Perfectionism Scale to measure generational changes in perfectionism from the late 1980s to 2016. During their analysis, Curran and Hill investigated three types of perfectionism:

l. Self-oriented perfectionism: having an irrational desire to be perfect on oneself.

2. Other-oriented perfectionism: Placing unrealistic standards of perfection on others.

3. Socially-perfectionism: Feeling excessive expectations of perfection from others.

The statistics are alarming: Between 1989 and 2016, self-oriented perfectionism scores increased by 10 percent, other-oriented perfectionism increased by 16 percent, and socially-perfectionism increased largely by 33 percent.

The rise in perfectionism among college students is driven by a variety of factors, according to Curran. The raw data suggests that the growing use of social media could be fueling the pressure young adults feel to perfect themselves in comparison to others. That said, Curran emphasizes that more research is needed to confirm the relation between an increase in social media usage and increased perfectionism.

Curran also assumes that college students' drive to perfect their grade point average represents a rise in meritocracy (精英教育) among the new generation.

“Today's young people are competing with each other in order to meet societal pressures to succeed and they feel that perfectionism is necessary in order to feel safe, socially connected and of worth.” Curran said.

Andrew Hill sees these findings as a strong call for colleges and policymakers to increase their efforts to control unnecessary competition among young people in order to preserve their mental health. Unfortunately, this may be easier said than done.

1What does the underlined word “flawless” in the first paragraph probably mean?

A.without effortB.without competition

C.without weaknessD.without strength

2What can you infer from the passage?

A.All college students of this generation have serious perfectionism.

B.Self-oriented perfectionism increased the most according to the latest study.

C.The increase in perfectionism is completely driven by some obvious factors.

D.It is uncertain whether increased social media usage causes more perfectionism.

3What's the writer's attitude toward the effect of the study on the change of the situation?

A.Concerned.B.Negative.

C.Positive.D.Critical.

【題目】 Joseph Francis Charles Rock (1884–1962) was an Austrian-American explorer, botanist, and anthropologist(人類學家). For more than 25 years, he travelled extensively through Tibet and Yunnan, Gansu, and Sichuan provinces in China before finally leaving in 1949.

In 1924, Harvard sent Joseph Francis Rock on a treasure hunt through China’s southwestern provinces—the Wild West of their day. But gold and silver weren’t his task : Rock, a distinguished botanist, sought only to fill his bags with all the seeds, saplings, and shrubs he could find. During his three-year expedition, he collected 20,000 specimens for the Arnold Arboretum(阿諾德植物園).

Botany, though, was just one of Rock’s strengths. As an ethnologist(民族學者), he took hundreds of photographs of the Naxi, a tribe in Yunnan province, recording their now-lost way of life for both Harvard and National Geographic, and took notes for an eventual 500-page dictionary of their language. His hand-drawn map of his travels through China’s “Cho-Ni” territory, in the Harvard Map Collection, includes more than a thousand rivers, towns, and mountains indicated in both English and Chinese, and was so well made that the U.S. government used it to plan aerial missions in World War II.

Scientist, linguist, cartographer, photographer, writer—Rock was not a wallflower in any sense. Arrogant and self-possessed, he would walk into a village or warlord’s place “as if he owned the place,” said Lisa Pearson, the Arboretum’s head librarian.

In declaring his successful return under the headline “Seeking Strange Flowers, in the Far Reaches of the World” , the Boston Evening Transcript ran a large photo of the daring explorer wearing in a woolly coat and fox-skin hat. “In discussing his heroism including hair-raising escapes from death either from mountain slides, snow slides and robber armies, he waves the idea away as if it is of no importance.”

The Arboretum and Rock parted ways after 1927, mainly because his trip cost Harvard a fortune—about $900,000 in today’s dollars. Fortunately, many of his specimens, many of his amazing photos, and his great stories remain.

1What is the passage mainly about?

A.Rock’s service for the U.S government.

B.Rock’s cooperation with Harvard.

C.Rock’s work as a botanist.

D.Rock’s exploration in Southwest China.

2What contribution did Rock make to the USA besides collecting new plants and specimens?

A.He traveled through some uncivilized places in China.

B.His hand-drawn map was used in WWII.

C.He showed heroism by escaping difficulties.

D.He made headlines in Boston Evening News.

3How did Rock respond when people mentioned his heroic deeds?

A.Excitedly.B.Proudly.

C.CalmlyD.Nervously.

4What caused Rock to stop work for The Arboretum?

A.The vast expense.B.The dangerous journey.

C.The challenging tasks.D.The unknown world.

【題目】 I believe that my actions show my beliefs, not my words.

I wrote a letter to my kids a few years ago. It’s three pages long, and it sums up my life experience of four decades. By the time they reach adulthood, they will have heard most of their father’s advice in that letter: live in the moment, do not attach yourself to physical things, treat others the way you would like to be treated, etc. I sealed the letter in a white envelope, and wrote instructions that nobody should open it unless something horrible happened to me.

As a police officer, I have seen life disappear in an instant. I realize that could happen to me at any time. Yet knowing that letter is there in my locker makes me more comfortable with my own death.

Every day, when I open my locker, I see the letter. It makes me aware that I should be careful at work, and show my children and the people I have connection with that I try to practice everything I have written. If that day comes and my children finally read the letter, I hope that because of my actions, they will take my written beliefs to heart and improve upon my example.

But for me, it’s not enough to write down my beliefs. I try to be the best person I can be every day-even in very difficult circumstances. I am more successful some days than others, but sometimes I curse too much. Sometimes I am cynical, unwilling to believe that people have good and honest reasons for doing something. I also get stressed and upset, yelling at my kids sometimes, and sometimes I am not as loving or as sympathetic as I should be. In fact, I am far from perfect, but I hope my children will eventually realize that perfection is an illusion. What really matters is that, instead of just writing down our beliefs, we all take action to be the best humans we can be.

1Which of the following can best describe the author?

A.Humorous.B.Interesting.

C.Selfless.D.Considerate.

2Why did the author open the locker to see the letter every day?

A.He wanted to confirm his beliefs.B.The letter served as a reminder.

C.He kept adding something new to it.D.His kids asked him to check it.

3Which can replace the underlined word “cynical” in the last paragraph?

A.Doubtful about others’ motivations.B.Curious about everything around.

C.Worried about his future life.D.Unsatisfied about his profession.

4What is the author’s understanding of life?

A.Parents should care for children.B.To become a successful father.

C.To be better today than yesterday.D.Bad guys deserve to be punished.

【題目】 A few years ago, a doctor gave a wrong prescription to a 9-year-old boy because he had accidentally clicked the next medicine listed in the drop-down menu. Unfortunately, the boy died.

Dr. Gidi Stein heard the story and felt forced to do something. “It was like killing someone with a spelling error. He just clicked on the wrong button,” Stein said. “One would have thought there’d be some kind of spell-checker to prevent these terrible things from happening. But apparently this is not the case.”

Several things were immediately obvious to the 54-year-old Stein, who had previously studied computer science. “If you look at this problem from a bird’s eye view, there were so many places down the line where this decision could have been stopped — from the physician to the pharmacy (藥房) even to the mother. All of them had all the relevant information to have a judgment call that this was just the wrong drug for the wrong patient.” For Stein, it represented a systemic failure.

Stein compared this with credit cards. “If you use your credit card in the daily routine over time, a pattern of how we use our cards comes out: the grocery store, the gas station in our local town. If your credit card would appear tomorrow in Zimbabwe, it would be unusual. The credit card company would call you and say, ‘Hey, was that you?’”

But nothing like that existed in the field of prescription drugs. So Stein set up a company called MedAware. He came up with a machine learning outlier detection (異常檢測值) system. In other words, he trained the computers to realize if a doctor accidentally prescribed the wrong medicine.

The system is already used in hospitals and doctor’s offices. To date, MedAware has used their technology to help nearly six million patients in the United States and Israel.

1What led to the boy’s death?

A.The doctor’s carelessness.B.The drawback of the computer.

C.The doctor’s poor medical skill.D.The incomplete health care system.

2What does Stein feel about this medical accident?

A.Angry.B.Frightened.

C.Embarrassed.D.Regretful.

3What can MedAware’s technology do?

A.Help doctor choose right medicine.B.Reminds patients to take medicine.

C.Introduce new drugs to doctors.D.Check the prescription.

4Where is this text most likely from?

A.A diary.B.A guidebook.

C.A magazine.D.A science fiction.

Steve was the most amazing person in all of Minneapolis, and he was my cousin. By the age of 19, Steve was a star baseball player at the University of Minnesota. I wanted to be exactly like him. So when Steve asked me to go with him on a spring fishing trip in northern Minnesota, I was excited!

After planning the trip, we gathered clothes and supplies, and began our great adventure. We reached the Superior National Forest in northern Minnesota by early evening. On our way to the campsite, Steve pointed to a small house faraway in one of the mountains, saying that it was the ranger station (護林站) where the forester worked.

Finally, after a long walk, we reached the campsite and set up the camp as the sun was setting. Steve knew all the tricks of an experienced wilderness camper. After we gathered enough wood from the forest, he started the campfire using only stone and steel — no matches. For supper we feasted on freeze — dried beef, wild rice and pea soup. I ate greedily after all that work.

Tired enough, we climbed into our sleeping bags early and talked about our plans for fishing the next day. We were still talking quietly when a sudden north wind picked upthe temperature dropped and it began to snow. Steve found a way to increase the temperature inside the tent. He dragged a log from the forest to the opposite side of the campfire. Then he wrapped aluminum foil (鋁箔) around the log. The heat from the fire reflected off the foil and into the tent. Soon images of lake fish were filling my dreams.

The snow had stopped, but sometime later a powerful wind must have kicked up the flames of our dying fire. I was suddenly awakened by Steve. Our tent was on fire. Frightened, I ran out of the tent immediately. The tent collapsed 倒塌) with Steve inside. Without any thought of endangering myself, I reached into the burning tent and pulled him to the icy lake. Fortunately, we were not seriously hurt.

【題目】 Male frogs use territorial calls to warn off frogs that are entering their territory. 1. So they do not waste energy by making territorial calls when they detect those frogs near their territory. However, if an unknown frog approaches the land they claim as their own, males will aggressively let out a territorial call.2.

Warning calls are employed to warn other frogs of some nearby danger and are commonly heard when an attacker comes near.3. If an attacker attacks a frog, the frog will make a call almost like a scream, which is intended to scare the attacker. This scream is almost always made when the attacker succeeds in grasping the frog because, should it be greatly surprised, the attacker may release the frog, which might permit the animal to make its escape.

4, which is employed when another frog is caught hold of by mistake. This regularly happens during the mating season, when male frogs eager for a mate wrongly grasp another male. In other cases, females that have already mated may make this call when different male frogs catch them.5.Whenever a male catches a female of another species, the female gives the release call to inform the male that he has made a mistake and should let go.

A.Frog calls further differ between species

B.The final major call made by frogs is the release call

C.To the human ear, frog mating calls may all sound similar

D.Frogs make short, sharp, loud sounds while they hurry away

E.Males can recognize the calls their neighbors make from afar

F.If the strange frog does not leave immediately, it may be attacked

G.There are some special occasions when frogs belonging to different species mix with one another
