Good Morning Britain's Susanna Reid is used to grilling guests on the sofa every morning，but she is cooking up a storm in her latest role - showing families how to prepare delicious and nutritious meals on a tight budget。
In Save Money: Good Food, she visits a different home each week and with the help of chef Matt Tebbutt offers top tips on how to reduce food waste, while preparing recipes for under ￡5 per family a day. And the Good Morning Britain presenter says she's been able to put a lot of what she's learnt into practice in her own home, preparing meals for sons, Sam, 14, Finn, 13, and Jack, 11.
“We love Mexican churros so I buy them on my phone from my local Mexican takeaway restaurant, "she explains. "I pay ￡5 for a portion （份），but Matt makes them for 26p a portion, because they are flour, water, sugar and oil. Everybody can buy takeaway food, but sometimes we 're not aware how cheaply we can make this food ourselves.”
The eight-part series(系列节目), Save money: Good Food, follows in the footsteps of ITV's Save Money：Good Health, which gave viewers advice on how to get value from the vast range of health products on the market.
With food our biggest weekly household expense, Susanna and Matt spend time with a different family each week. In tonight's Easter special they come to the aid of a family in need of some delicious inspiration on a budget. The team transforms the family's long weekend of celebration with less expensive but still tasty recipes.

Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers，small，tightly knit(联系)groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12, 000 languages between them.
Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialisation, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English，Spanish and Chinese are increasingly taking over.
At present, the world has about 6, 800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages, often spoken by many people, while hot wet zones have lots, often spoken by small numbers. Europe has only around 200 languages; the Americas about 1, 000; Africa 2, 400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800.The median number(中位数) of speakers is mere 6,000, which that half the world's languages are spoken by fewer people than that.
Already well over 400 of the total of 6, 800 languages are close to extinction (消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon （eight remaining speakers), Chiapaneco in Mexico (150), Lipan Apache in the United States (two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival.

We may think we’re a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置)well after they go out of style. That’s bad news for the environment- and our wallets - as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life - from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s.Devices were grouped by generation. Desktop computers， basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997.And WP3 players, smart phones, and LCD TVs entered homes in 2002，before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids’ room, and suddenly one day ，you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We’re not just keeping these old devices - We continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.
So what' s the solution(解决方案)? The team' s data only went up to2007， but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
32. What does the author think of new devices?
33. Why did Babbitt's team conduct the research?
34. Which of the following uses the least energy?

During my second year at the city college,I was told that the education department was offering a “free” course, called Thinking Chess, for three credits. I 41 the idea of taking the class because, after all, who doesn’t want to 42 a few dollars? More than that, I’d always wanted to learn chess. And, even if I weren’t 43 enough about free credits, news about our 44 was appealing enough to me. He was an international grandmaster, which 45 I would be learning from one of the game’s 46 I could hardly wait to 47 him.
Maurice Ashley was kind and smart, a former graduate returning to teach, and this 48 was no game for him ; he meant business. In his introduction, he made it 49 that our credits would be hard-earned. In order to 50 the class among other criteria, we had to write a paper on how we plan to 51 what we would learn in class to our future professions and 52 .to our lives. I managed to get an A in that 53 and leaned life lessons that have served me well beyond the 54 .
Ten years after my chess class with Ashley, I' m still putting to use what he 55 me：“the absolute most important 56 that you learn when you play chess is how to make good 57 . On every single move you have to 58 a situation, process what your opponent (对手) is doing and 59 the best move from among all your options.” These words still ring true today in my 60 as a journalist.

During my last winter holiday, I went to countryside with my father to visit my grandparents. I find a big change there. The first time I went there, they were living in a small house with dogs, ducks, and another animals. Last winter when I went here again, they had a big separate house to raise dozens of chicken. They also had a small pond which they raised fish. My grandpa said last summer they earned quite a lot by sell the fish. I felt happily that their life had improved. At the end of our trip，I told my father that I planned to return for every two years, but he agreed.
