In the past 12 months,Nigeria has suffered from a shrinking economy, a sliding currency, and a prolonged fuel shortage. Now, Africa’s largest in facing a food crisis as major tomato fields have been destroyed by an insect,leading to a nationwide shortage and escalating prices.
The insect, Tutaabsoluta, has destroyed 80% of farms in Kaduna, Nigeria's largest tomato producing state, leading the government there to declare a state of

In Nigeria, where tomatoes are a staple of local diets,the insect's effects are devastating. Retail prices for a 30 of tomatoes at local markets have risen from $0. 50 to $2.50. Farmers are reporting steep losses and a new $20 million tomato-paste factory has 31 production due to the shortages.

who's really addicting you to Technology?
A."Nearly everyone i know is addicted in some measure to the internet, "wrote tony Schwartz in The New York Times. it's a common complaint these days. A steady stream of similar headlines accuse the net and its offspring apps, social media sites and online games of addicting us to distraction
B. There's little doubt that nearly everyone who comes in contact with the net has difficulty concentration than it takes to post a status update. as one person ironically put it in the comments section of Schwartz's online article, "As I was reading this very excellent article.I stopped at least half a dozen times to cheek my email.
C.There's something different about this technology: it is both invasive and persuasive. but who's at fault for its overuse? To find solutions, it's important to understand what we’re dealing with.There are four parties conspiring to keep you connected the tech, your boss, your friends and you.
D.The technologies themselves and their makers, are the easiest suspects to blame for our diminishing attention spans. Nicholas Carr,author of The Shallows： what the internet is doing Our brains, wrote, The net is designed to be an interruption system, a machine geared to dividing attention.
E.Online services like Facebook, twitter and the like, are called out of manipula-tion--making，products so good that people can't stop using them. after studying these products for several years, I wrote a book about how they do it. I learned it all starts with the business model. since these services rely on advertising revenue, The more frequently you use money they make.It’s no winder these companies employ teams of people focused on engineering their services to be as engaging as possible. these products aren't habit-forming by chance; it's by design. they have an incentive to keep us hooked.
F.However, as good as these services are, there are simple steps we can take to keep them at bay.For example, we can change how often we receive the distracting notifications that trigger our urge to check.According to adam marchick, ceo of mobile marketing company kahuna, less than 15 percent of smartphone users ever bother to adjust their notification setlings--meaning the remaining 85 percent of us default to the app makers' every preset trigger.Google and Apple have made it far too difficult to adjust these settings so it's up to us to take steps ensure we set these triggers to suit our own needs, not the needs of the app makers.
G.While companies like Facebook harvest attention to generate revenue from advertisers, other technologies have no such agenda. take email, for example. this system couldn't care less how often you use it. Yet to many, email is the most habit-forming medium of all.We check email at all hours of the day--we're obsessed, but why? Because that's what the boss wants.For almost all white-collar jobs, A slow
Response to a message could hurt not only your reputation but also your livelihood.
H.Your friends are also responsible.Think about this familiar scene.People gathered around a table, enjoying food and each others company. there's laughter and a bit of kidding. Then, during an interval in the conversation, someone takes out their phone to check who knows what.Barely anyone notices and no one says a thing.
I.Now imagine the same dinner,but instead of checking their phone, the person belches(打嗝)-loudly.Everyone notices. unless the meal takes place in a beer house, this is considered bad manners. The impolite act violates the basic rules of etiquette. one has to wonder why don’t we apply the same social norms to checking phones during meals, meetings and conversations as we do to other antisocial behaviors somehow, we accept it and say nothing when someone offends.
J.The reality is taking one's phone out at the wrong time is worse than belching because, unlike other minor offense, checking tech is contagious. once one person looks at their phone,other people feel compelled to do the same, starting a chain reaction. the more people are on their phones, the fewer people are talking until finally you are the only one left not reading email or checking twitter. from a societal perspective, phone checking is less like belching in public and more like another bad habit. our phones are like cigarettes-something to do when were bored or when our fingers need something to toy with seeing others enjoy a smoke,or sneak a quick glance, is too tempting to resist and soon everyone is doing it.
K.The technology, your boss, and your friends, all influence how often you find yourself using (or overusing )these gadgets. but there's still someone who deserves scrutiny--the person holding the phone.
L. I have a confession. even though i study habit-forming technology for a living, disconnecting is not easy for me.I'm online far more than I'd like like Schwartz and so many others, I often find myself distracted and off tack.I wanted to know why so i began self-monitoring to try to understand my behavior. that's when i discovered an uncomfortable truth. i use technology as an escape. when I'm doing something I'd rather not do, or when I'm someplace I'd rather not attention was often a good thing, like when passing time on public transportation, but frequently my tech use was not so benign. when i faced difficult work, like thinking through an article idea or editing the same draft for the hundredth time, for example, a more sinister screen would draw me in. i could easily escape discomfort.temporarlly.by answering email or browsing ing the web under the pretense of so-called"research. "though I desperately wanted to lay blame elsewhere, i finally had to admit that my bad habits had less to do with new-age.technology and more to do with old-fashioned procrastination(拖延)
M.it's easy to blame technology for being so distracting, but distraction is nothing new. Aristotle and Socrates dehated nature of “akrasia”--our tendency to do things agninst our interests. If we're honest with ourselves, tech is just another way to occupy our time and minds,if we weren’t on our devices. We’d likely do similarly unproductive.
N.personal technology is indeed more engaging than ever, and there's no doubt companies are engineering their products and services to be more compelling and attractive but would want it any other way the intended result of making something better is that people use it more. that's not necessarily a problem, that's progress.
O.These improvements don't mean we shouldn't attempt to control our use of technology. In order to make sure it doesn't control us, we should come to terms with the fact that it's more than the technology itself that’s responsible for our habits. our workplace culture, social norns and individual behaviors all play a part to put technology in its place, we must be conscious not only of how technology is changing, but also of how it is changing us.
36.Online services are so designed that the more they are used, the more profit they generate.
37. The author admits using technology as an escape from the task at hand.
38. Checking phones at dinners is now accepted as normal but not belching
39. To make proper use of technology, we should not only increase our awareness of how it is changing but also how it is impacting us.
40. Most of us find it hard to focus on our immediate tasks because of internet distractions
41. when one person starts checking their phone, the others will follow suit.
42.The great majority of smartphone users don' t take the trouble to adjust their settings to suit their own purposes.
43.The internet is regarded by some as designed to distract our attention.
44. The author attributes his tech addiction chiefly to his habit of putting off doing what he should
