A couple of weeks ago, when we were leaving one of those horrible giant trampoline bouncy(弹跳床)places, my 11－year－old daughter said to me, “I don't think I'm very athletic, you know, like Rocket (her brother). He seems to be really good at ______.”
What came out my mouth ______ me: “No, you're kind of not.”
Okay, let me ______. As you may have guessed, this child has been with me for about 11 years, so I've had enough time to ______ her engaging in physical acts: jumping, climbing, running, and organized sports.
And the kid is just ______ me: two left feet. If anybody was ever NOT a “natural”______， that person is me.
But even ______ these facts, my first instinct(本能反应)was to show her with some ______： “Oh, no honey. You're good at sports! You just have to keep ______！” But I decided to tell her the ______， and I could see it hurt a bit.
So I said more: “Ava, we all have things we are particularly, ______ good at. Like you and ______. You're in the 5th grade and read Charles Dickens. That isn't ______， but you've done it without even trying. But all of us also have things that we are ______ in. If we wan to get good at those things, we have to put in twice the ______ of the people around us to get to a decent(相当的)point and even harder if we want to ______.”
She was nodding. She totally ______ it. Why? Because it's the truth. Sometimes I wonder why we run around talking nonsense(胡扯)to our kids when they can ______ the truth. And they can smell rubbish from a mile away. In other words, they can easily recognize you are ______. In addition, if they don't know where they ______ now, they'll never know how to get somewhere new.

Color is fundamental in home design—something you’ll always have in every room. A grasp of how to manage color in your spaces is one of the first steps to creating rooms you’ll love to live in. Do you want a room that’s full of life? Professional? Or are you just looking for a place to relax after a long day? 1., color is the key to making a room feel the way you want it to feel.
Over the years, there have been a number of different techniques to help designers approach this important point. 2., they can get a little complex. But good news is that there’re really only three kinds of decisions you need to make about color in your home: the small ones, the medium ones, and the large ones.
3.. They’re the little spots of color like throw pillows, mirrors and baskets that most of us use to add visual interest to our rooms. Less tiring than painting your walls and less expensive than buying a colorful sofa, small color choices bring with them the significant benefit of being easily changeable.
Medium color choices are generally furniture pieces such as sofas, dinner tables or bookshelves. 4.. They require a bigger commitment than smaller ones, and they have a more powerful effect on the feeling of a space.
The large color decisions in your rooms concern the walls, ceilings, and floors. Whether you’re looking at wallpaper or paint, the time, effort and relative expense put into it are significant. 5..
A. While all of them are useful
B. Whatever you’re looking for
C. If you’re experimenting with a color
D. Small color choices are the ones we’re most familiar with
E. It’s not really a good idea to use too many small color pieces
F. So it pays to be sure, because you want to get it right the first time
G. Color choices in this range are a step up from the small ones in two major ways
A series of climate reports showed that temperatures on Earth are rising.That is the bad news.The good news is that countries are working together to fight climate change.Michael Oppenheimer is a professor of geosciences and international affairs.He says air pollution emissions must be reduced before temperatures rise.
The recent United Nations talks in Peru were designed to prepare officials for a meeting in Paris, France later this year.Many nations will sign a global climate agreement at that meeting.The agreement reached in Peru is different from earlier agreements.Developing countries like China and India are promising to join richer countries in reducing emissions.U.S.Secretary of State John Kerry said developing nations are having a large effect on the environment.“More than half of global emissions—more than half—are coming from developing nations.So it is imperative that they act, too.”
China and the United States acted—they signed an agreement.American officials said the U．S.would reduce emissions between 26 and 28 percent by 2025.China said it would begin reducing emissions in 2030.Michael Oppenheimer says other countries will release their environmental plans early this year.He says negotiators continue to discuss details of the agreement before the conference opens in Paris.But he says he hopes people understand that an agreement is just the beginning of efforts to reduce global warming.
Experts say a two－degree rise in temperature above pre－industrial times will cause serious damage that cannot be reversed (逆转)．The pre－industrial period ended in the middle of the 18th century.That was followed by the Industrial Revolution, when machines and new manufacturing processes were created.Professor Oppenheimer says if countries do not take action the planet will become warmer faster than at any time in the history of civilization.

A deal has been signed to turn byproducts from a Scottish distillery (酿酒厂) into fuel for cars.
In what is declared to be a world first, the Tullibardine distillery in Perthshire has linked up with a spin－out company from Napier University in Edinburgh.They plan to use bacteria to feed on the “leftovers” from the whisky (威士忌酒) making process.This will produce butanol which can be used to fuel vehicles.
More than 90% of the stuff that comes out of a whisky distillery is not whisky.It is leftovers like draff and pot ales (酒糟)—both produced in the early stages of the process.They are high in sugar and are currently used for things like fertiliser and cattle feed.Napier University's Biofuel Research Centre (BfRC) has already shown that the right bacteria can feed on those by－products to produce butanol－a direct replacement for vehicle fuel.Now the spin－out company, Celtic Renewables, and independent whisky producer Tullibardine have signed an agreement.Together they will apply the process to thousands of tons of the distillery's leftovers.
Professor Martin Tangney, founder of Celtic Renewables, said Our partnership with Tullibardine is an important step in the development of a business which combines two important Scottish industries—whisky and renewables.This project shows that creative use of existing technologies can utilize resources on our doorstep to benefit both the environment and the economy.
Douglas Ross, managing director of Tullibardine, which spends ￡250,000 disposing of its by－products every year, said “We are delighted to be partnering Celtic Renewables in this creative business, the obvious benefits of which are environmental.It takes a cost to us and turns it into something that has social as well as commercial value.”
The project is being supported by a grant(拨款) from the Scottish government's Zero Waste Scotland initiative. Celtic Renewables said it eventually aimed to build a processing plant in Scotland, with the hope of building an industry that could be worth ￡60m a year.

Plastic-Eating Worms
Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.
Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms’ chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms’ stomachs. Their findings were published in Current Biology in 2017.
Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. ＂Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, ＂she explains, ＂The wax worm evolved a method or system to break this bond. ＂
Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?
Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply ＂millions of worms thrown on top of the plastic.＂
1.What can we learn about the worms in the study?
A. They take plastics as their everyday food.
B. They are newly evolved creatures.
C. They can consume plastics.
D. They wind up in landfills.
2.According to Jennifer DeBruyn, the next step of the study is to .
A. identify other means of the breakdown
B. find out the source of the enzyme
C. confirm the research findings
D. increase the breakdown speed
3.It can be inferred from the last paragraph that the chemical might .
A. help to raise worms
B. help make plastic bags
C. be used to clean the oceans
D. be produced in factories in future
4.What is the main purpose of the passage?
A. To explain a study method on worms.
B. To introduce the diet of a special worm.
C. To present a way to break down plastics.
D. To propose new means to keep eco-balance.
