Hello Feifei. I didn't know you shopped at this supermarket too.

00:00:05,354 –> 00:00:12,303
Hi Finn. Usually I don’t. But it’s close to the office and I have to rush home to welcome an important guest.

00:00:13,378 –> 00:00:15,321
Who is it? Someone I know?

00:00:15,402 –> 00:00:29,763
No, it’s my landlady. She’s coming to collect some of her post and… well, I want to make her like me because next month, the contract on my flat is due to be renewed and she might want to increase the rent.

00:00:30,426 –> 00:00:34,919
Yeah, I see what you mean. So you’d better butter her up then!

00:00:35,450 –> 00:00:43,498
Butter? Oh, yes. But I’m a pretty bad cook. If I baked a cake it would probably be horrible!

00:00:44,474 –> 00:00:56,703
No. I don’t mean butter for a cake. In English, when you say you’ll ‘butter someone up’, you mean you’ll be especially nice to them in the hope they’ll do something good for you in return.

00:00:57,498 –> 00:01:08,424
Oh, I see. So I’ll be nice to her and pay her compliments so that she likes me and keeps the rent low. I’ll ‘butter her up’! But isn’t it a bit insincere?

00:01:09,522 –> 00:01:22,522
Well, it can have a negative connotation, yes. Let’s hear some examples of how to use ‘to butter someone up’ or ‘to butter up someone’, which is today’s expression in The English We Speak.

The Internet of Things

Hits: 604  

In the modern era, the era of the Internet of Things, what tech best suits you can be difficult to ascertain. It may seem at times that there are just too many smartphones, too many TVs, too many computers, and then some. Shopping for gadgets can sometimes be a bit complicated for the layperson. Specifications for computers, for example, can seem like a calculus problem or a foreign language.

With so many options to choose from, it’s helpful to be able to narrow down your options and focus your search. An example of this is the current transition from High Definition television to the burgeoning 4k Ultra High Definition. It’s safe to say most consumers don’t necessarily know the difference between these labels and, even if you told them, might not know much beyond the difference in numbers. Knowing that 4K UHD TVs, being the hot new tech, are more expensive than HD TVs, and that HD is already more than enough for the average Joe, one can safely restrict their search to HD and save a little money on their purchase.

Beyond the question of what specs matter to what consumer, there is the question of brands. So, you now know you want HD TV, instead of 4K, but which HD TV is the best? There a great many brands competing for your money, and now you need to know which brand has the best balance of price and quality. To get the most bang for your buck without doing a ton of research, it’s often a great idea to do price comparisons first. Budget is more often than not the biggest deciding factor when making purchases.

Supposing you’re in the market for a smartphone, the two big names in the spotlight are the iPhone and the Samsung Galaxy. Apple’s claim to fame is ubiquitous in its popularity, but Samsung’s rival Galaxy series of phones is the quality, cost-effective alternative.
