1 . Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter. This process requires you to step away from optional online activities for thirty days. At the end of the thirty days, you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.
What does the underlined word “declutter” in paragraph 3 mean?A.Clear-up. | B.Add-on. | C.Check-in. | D.Take-over. |
2 . Instantly, we were busily preparing for the worst. The whole family had experienced such a storm before and everyone remembered the damage it had caused to stock and crops. There was very little we could do about the crops. But we needed to protect the animals in case the river flooded again. My older brother called his sheep-dog and began driving our small flock of sheep to higher ground above river. If the river flooded, they should be safe there.
The underlined word “stock” in the paragraph above refers to _______.A.money owned by the family | B.goods for sale |
C.supplies for family use | D.farm animals |
3 . When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.
The fur trade kept nutria in check for decades,but when the market for nutria collapsed in the late 1980s,the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashion. Model Paige Morgan says,”To give people a guilt-free option that they can wear without someone throwing paint on them-1 think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a lable to attach to nutria fashions to show it is eco-friendly.
What does the underlined word “collapsed” in paragraph 5 probably mean?A.Boomed. | B.Became mature. | C.Remained stable. | D.Crashed. |
4 . People’s sensitivity to blood sugar is also dampened when they’re tired, the study found, which suggests those who don’t sleep well are at higher risk of type 2 diabetes. “We saw that the fatty tissue is attempting to increase its capacity to store fat following sleep loss.” said Dr Cedernaes, “And we observed signs of breakdown of skeletal muscle. We also noted changes in levels of proteins involved handling blood glucose. This could help explain why the participants’ glucose sensitivity was impaired following sleep loss.”
What does the underlined word “dampened” in paragraph 4 mean?
A.Decreased. | B.Transformed. |
C.Transmitted. | D.Promoted. |
5 . Plastic tubes hook up to the taps and connect them to one another. The sap flows into a collection tank in the woods. From the collection tank, the Gagnes pump the sap into a ma-chine to remove a lot of the sap’s water. Then it’s moved into an evaporator in a building called “sugar house”. The Gagnes make a fire out of maple wood chips. The fire heats the sap and boils it. When it reaches 219 degrees, the syrup is ready to be made.
Syrup is poured into glass or plastic bottles. But 150 years ago, sugar makers used tin cans. These containers could prevent syrup from seeping out and allowed them to ship it far from home and helped maple become a big business.
What does the underlined word “seeping” in paragraph 4 probably mean?
A.Breaking. | B.Blowing. | C.Looking. | D.Leaking. |
6 . One explanation for this strong statistical pattern is that traveling requires time and energy, and people have limited resources for it. At the core is the effort that people are willing to invest collectively to travel to certain locations, trying to optimize their days.
What does the underlined word “optimize” in Paragraph 4 probably mean?
A.Slow down. | B.Keep a record of. |
C.Think back on. | D.Make the most of. |
7 . The yogurt that’s past its sell-by date. The banana in your lunch that turned brown. The leftovers in the fridge that you forgot to eat. For most people, all that food goes right into the garbage can.
Eight to ten percent of global greenhouse gas emissions (放) are related to food waste, according to a report by the U. N.’s Intergovernmental Panel on Climate Change. “When you throw away an egg or a sandwich,” says Yvette Cabrera, food waste vice director at the Natural Resources Defense Council (N. R. D.C.) ,“you’ re also throwing away all the resources that went into producing those things.”
That includes not only all the water, land, and fertilizer (化肥) that went into producing that food, but also the massive amounts of fossil fuels used to power the farms, transport the food, and create the packaging.
What does the underlined word “That” in Paragraph 3 refer to?
A.The leftovers in the fridge. | B.The packaging for products. |
C.The thrown egg or sandwich. | D.The resources to produce food. |
8 . Besides, 10% of rich countries greenhouse gas emissions come from food that was grown and never eaten. Food waste not only contributes to climate change, but also food insecurity and extreme poverty. As stated above, in the greatest food wasting countries, there are laws that confine produce from being donated to people in need.
What does the underlined word “confine” in paragraph 3 probably mean?
A.Refuse. | B.Restrict. | C.Contact. | D.Protect. |
9 . 30 years later, Bob and his wife, Jill Welch, decided to turn their wedding into a fundraiser for the Make-A-Wish Foundation. Their wedding guests financed two wishes for local children, more being planned. Many donated generously to the cause, spending more, perhaps, than they might have if it was just to buy the couple a wedding gift like fine china or a kitchen appliance. Bob said their wedding donation to the Make-A-Wish Foundation isn’t going to be “one and done”. The two plan on continuing to contribute going forward.
What does the underlined part “one and done” in Paragraph 2 mean?
A.Once-only. | B.Non-stop. | C.Sizable. | D.Personal. |
10 . The world is getting greener, according to a new study published in Nature this week.
Chi Chen, lead author of the study, and his colleagues have been mining data collected by an orbiting NASA camera that monitors green vegetation on Earth’s surface, day by day. Even more interesting: They are able to show the exact causes of increasing or decreasing leaf cover in particular areas.
In some cold places, increase in leaf cover apparently resulted from global warming. Since the climate is becoming more and more temperate and the growing season is getting longer and longer, the plants are growing bigger and leafier there.
Which of the following best explains the underlined word “temperate” in paragraph 3?
A.Warm. | B.Wet. |
C.Cold. | D.Dry. |
