1 . To produce the classic clothing, blue jeans, producers rely on indigo dye (靛蓝染料), the only molecule known to provide jeans’ unique, beloved color. While indigo itself naturally comes from a plant, growing demand for blue jeans throughout the 20th century gave rise to synthetic (合成的) indigo, which is now more commonly used.

Indigo is the dye that makes jeans blue, but it doesn’t mix with water. To dye clothes, usually, chemicals are needed to make the color stick to the cloth. But in Denmark, scientists have created a new way to dye clothes using an enzyme (酶), which is a kind of protein that can cause chemical reactions, instead of harmful chemicals. This new method is better for the environment and doesn’t use poisonous stuff.

The chemical process for dyeing blue jeans has persisted for the last century. Workers are exposed to the poisonous chemicals, which also pollute the environment near factories. Waste water from those factories often ends up in waterways, decimating local ecosystems and even dyeing rivers blue.

Ditte Hededam Welner, the study’s lead researcher, says their new enzyme works really well and is strong enough for making lots of jeans without breaking down. This enzyme makes dyeing with indican, which is like indigo, much less harmful to the planet — about 92% better than the old way.

However, the new method doesn’t fix all the environmental problems of making jeans. Making a single pair of jeans uses a lot of water — enough to fill many bathtubs — from growing the cotton to putting the final touches on the jeans.

Even though the new dyeing process is better for the environment, it’s not always easy or cheap to change to it. Welner’s team isn’t sure if jeans companies will find it easy or affordable to switch to this method. It costs a little bit more — just seven cents extra per pair of jeans — to use the enzyme for dyeing. But Welner believes it’s worth it because it’s much better for the environment.

2 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Holding fist is a form of ceremony originating from Chinese martial arts (武术). Traditionally, it is practiced by standing upright,     1     the body straight, holding the right fist tightly, straightening your left hand     2     (have) four fingers in a flat surface, wrapping the left four fingers together around the right fist and placing the two hands in front of your chest, without bringing the     3     (arm) up.

There are two traditional explanations for     4     practice. The left hand with its four fingers represents the four elements: virtue, wisdom, health, and art, all of     5     symbolize the spirit of martial arts. The left thumb (拇指) is slightly bent to imply that one should never be self-centered. Since the right hand is closed in a fist, it symbolizes attack; while the left hand, being virtuous and disciplined, stops the attack and symbolizes self-discipline and     6     (restrict).

The left hand symbolizes the five major lakes of China and the fist represents the four seas     7     (surround) the country. The two hands together show the unity of martial artists. This is exemplified in the saying “The people of the five lakes and four seas are all brothers”.

The holding fist can     8     (see) at every major Chinese event or festival, such as the Spring Festival. On festive occasions like weddings or birthday parties, guests can hold fist to express     9     (they) congratulations to the hosts. At farewell parties, people often hold fist while saying "Take care!" to one another.     10     (occasion), we hold fist to request forgiveness.

5 . I didn’t quite know what I was looking for when I flew to Mongolia for a term abroad. I just needed something different, far from the late-night libraries of my college town. Most different, I hoped, would be my rural homestay: two weeks in central Mongolia with a family of nomadic(游牧的) herders.

I was studying Mongolian at the time, but still, there was so much I couldn’t say or understand. As we walked in the snow behind the goats, my host mom would ask me if I was cold, then giggle (咯咯地笑) and copy a big shiver to make sure I understood. In the evenings, she showed me how to make dumplings with her fingers. My host siblings would talk with me, speaking too fast for me to understand, as we explored the rocks around our tent; I’d listen and nod.

This verbal(言语的) barrier was strangely freeing. In the crowded dining hall at home, meeting new people made me anxious. I’d stay quiet, measuring out my words, struggling for something to say that wouldn’t expose me as unfunny or boring. In Mongolia, I couldn’t perfect my words. I could only smile, and try out one of the phrases I’d mastered: “May I help?” “Where is the dog?” “Are you tired?” My host family laughed at my pronunciation, at the way I threw up my hands and eyebrows in a frequent gesture of confusion. But in their laughter, I felt safe, unembarrassed.

With my Mongolian family on the grassland, I found a feeling of ease I’d never felt before. We were so different, they and I, and not just in language. Their skin was hardened and darkened by sun; I’d been hidden under hats and sunscreen since birth. My host siblings(兄弟姐妹) grew up drawing water from frozen streams and jogging behind herds of sheep; I spent summers at tennis camp.

For me, these gaps made all the difference. Without shared social measures, I wasted no time wondering how I was measuring up. Only real things—kindness, helpfulness—mattered.

6 . Many people love to listen to music while driving. Thanks to the world’s musical roads, drivers now don’t need to turn the radio on.     1    

A musical road can create music when a car tires go over grooves (凹槽) on the road. To produce beautiful music, drivers must pass over the grooves at a certain speed. Signs often tell drivers the right speed.

    2    . Since the mid-1990, musical rads have appeared in many different countries.     3    . To warn drivers to the incoming music, all the roads are marked by colored musical notes that are painted on these roads. Drivers can decide whether to go over the grooves or not because they are set on the side of the road.

In Hungary, there is a musical road in honor of one of the country’s most popular musical performers — Laszlo Bodi. Bodi was the lead singer for the band Republic.     4    . Sadly, Bodi passed away in 2013. But people still remember him as there’s a road where drivers can hear 30 seconds of the Republic song “Road 67”.

    5    . In Indonesia, a road plays the first six notes of “Happy Birthday”. The fifth note is a little out of tune, though. This “mistake” keeps drivers awake and aware, and it has reduced the number of traffic accidents. Such is the power of music and musical roads.

A．Musical roads are also keeping drivers safe.

B．There is not any music road in Eastern countries.

C．Musical roads help improve the road safety greatly.

D．But they can also enjoy music while taking road trips.

E．Formed in 1990, the group is one of Hungary’s biggest acts and is still active today.

F．The first musical road was created in Gylling, Denmark, in 1995.

G．For example, in Japan, there are many musical roads throughout the country.

7 . In a small, rough shipyard on the Pacific coast of Costa Rica, a small team is building what they say will be the world’s largest ocean-going clean cargo ship.

Ceiba is the first ship built by Sailcargo, a company trying to prove that zero-carbon shipping is possible, and commercially available. Made largely of wood, Ceiba combines both very old and very new technology: sailing masts stand alongside solar panels, a uniquely designed electric engine and batteries. Once on the water, she will be capable of crossing oceans entirely without the use of fossil fuels, which sets her apart.

“The thing that is striking is the fact that she’ll have one of the largest marine electric engines of her kind in the world,” Danielle Doggett said. The system also has the means to capture energy from underwater propellers (螺旋桨) as well as solar power, so electricity will be available for the engine when needed. “Really, the only limit on how long she can stay at sea is water and food on board for the crew.”

Despite some hold-ups due to the global disaster, the team hopes to get her on the water by the end of 2024 and operating by 2025, when she will begin transporting cargo between Costa Rica and Canada.

“There are actually loads of innovations happening that could transform shipping emissions, but few companies are willing to apply them to building ships like Ceiba.” says Lucy Gilliam. “So it’s not that we don’t have great ideas. The problem that we have is that fossil fuels are still too cheap. And we don’t have the rules to force people to take up the new technology.”

When it comes to promoting this kind of boat, it has to be said that Ceiba is small for a cargo ship — tiny in fact. She will carry around nine standard shipping containers. She is also relatively slow. Being a world-first, there are some aspects of Ceiba’s design that have yet to be proven at sea.

1. What is unique about Ceiba as a cargo ship?

A．It is the world’s largest.	B．It is environment-friendly.
C．It is wooden with old technology.	D．It is modern with unique equipment.

2. What determines Ceiba’s length of staying at sea according to Danielle Doggett?

A．The size of the sail.	B．The weather of the ocean.
C．The power of the electric engine.	D．The quantity of the living supplies.

3. Why are companies unwilling to build ships like Ceiba?

A．The rules are disobeyed.	B．The fuels are affordable.
C．The bigger ships are preferable.	D．The innovations are distrusted.

4. What is the author’s attitude to the innovation of Ceiba?

A．Objective.

B．Doubtful.

C．Critical.

D．Favorable.

8 . Proper questioning has become a lost art. The curious four-year-old asks a lot of questions-incessant streams of “Why?” and “Why not?“ might sound familiar-but as we grow older, our questioning decreases. In a recent survey of more than 200 of our clients, we found that those with children estimated that 70-80% of their kids’ dialogues with others were comprised of questions. But those same clients said that only 15-25% of their own interactions consisted of questions. Why the drop of?

Think back to your time growing up and in school. Chances are you received the most recognition or reward when you got the correct answers. Later in life, that motivator continues. At work, we often reward those who answer questions, not those who ask them. Questioning conventional wisdom can even lead to being distanced, or considered a threat.

Because expectations for decision-making have gone from ”get it done soon“ to ”get it done now“ to ”it should have been done yesterday, “ we tend to jump to conclusions instead of asking more questions. And the unfortunate side effect of not asking enough questions is poor decision-making. That’s why it’s vital that we slow down and take the time to ask more and better questions. At best, we’ll arrive at better conclusions. At worst we’ll avoid a lot of rework later on.

Aside from not speaking up enough, many professionals don’t think about how different types of questions can lead to different outcomes. We should lead a conversation by asking the right kinds of questions, based on the problem we’re trying to solve. In some cases, we’ll want to expand our view of the problem rather than keeping it narrowly focused. In others, we may want to challenge basic assumptions or confirm our understanding in order to feel more confident in our conclusions. Therefore, asking the right kinds of questions is what counts in achieving a goal.

1. What does the underlined word ”incessant“ in paragraph 1 most probably mean?

A．Constant.

B．Random.

C．Noisy.

D．Innocent.

2. What accounts for the decline of questioning in adulthood?

A．One poses a threat to the company if they ask questions.

B．Those who ask questions don’t necessarily get positive feedback.

C．One doesn’t have as many opportunities as they did in childhood.

D．Those who question popular beliefs don’t have interpersonal skills.

3. What can we infer from paragraph 3?

A．Redoing is unavoidable despite thoughtful questions.

B．Better questions can surely result in desirable outcomes.

C．Some people think it can’t be too fast to make a decision.

D．We’ll make reasonable decisions as long as we ask questions.

4. What might the author continue talking about?

A．Proper questions that should be raised.

B．Important goals that we are to achieve.

C．Right kinds of answers to the questions.

D．The reasons for the loss of questioning art.
