    Holiday season is drawing near. Choosing presents for your friends or loved ones is a hard nut to crack. 1.

Don’t try to price-match.

The first thing you should do when planning your gift list is to create a budget (预算) of how much you’re willing to spend — and stick to it, even if you receive a more expensive gift from someone else. “A void matching spending, because that’s when gift-giving is driven more by pressure than by thoughtfulness,” says Sharon Schweitzer, an international etiquette (礼节) expert and founder of Protocol Etiquette Worldwide. After all, loved ones dropping a lot of money on expensive gifts could probably afford expensive items on their own and aren’t looking for you to return the favor. 2.

Don’t give just because you did in the past.

When you’re figuring out whom to give to keep in mind your list might not have all the same people as last year’s. “You have to review it every year because you have relationships with different people, so you have to look at how those relationships have grown and developed,” says Schweitzer. 3. Even if you’ve exchanged gifts in the past, don’t feel you should give presents to friends who you haven’t kept in touch with much this year. Send a holiday card instead to show you’re thinking of them.

Be honest if you don’t have a gift.

If someone surprises you with a present you weren’t expecting, be honest that you don’t have one to give in return. 4. “Say you’re touched and delighted and a little embarrassed you don’t have anything for them.” says Schweitzer. Don’t try to think up a gift on the spot by taking something out of your closet suddenly, because the other person will likely know exactly what you’re doing.

5.

With the exception of family members or best friends, never ask people what they want for a present. “That makes people very uncomfortable, and they feel they ought to get you something in return,” says Schweitzer. Gift requests leave little creativity to the giver, so come up with your own ideas for a more thoughtful present.

A.Never ask for a wish list.

B.People come in and out of your life.

C.Have creative ideas when you choose gifts.

D.The best way to deal with that is to be honest and sincere.

E.Here are pieces of gift-giving etiquette you need this holiday season.

F.Expensive gifts are sometimes thoughtful items your friends selected.

G.Find a thoughtful gift instead, like a frame with an old favorite photo.

    Clothing rental (租赁) is a hot new industry and businessmen are trying their best to attract shoppers. This past summer alone, Urban Outfitters, Macy’s, Bloomingdale’s, and American Eagle have all announced rental subscription services — a sure sign of changing times.

But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline researched this question in an article for Elle, and she concluded that it’s not as green as it seems.

Take shipping, for example, which has to go two ways if an item is rented — receiving and returning. Cline writes that consumer transportation has the second largest footprint of our fashion habit after producing.

She writes, “An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases to 50 kilograms for rush shipping. However, the carbon effect of a pair of jeans bought in a store and washed and worn at home is 33.4 kilograms, according to a 2015 study.”

Then there’s the burden of washing, which has to happen for every item when it’s returned, regardless of whether or not it was worn. For most rental services, this usually means dry-cleaning is a high-effect and polluting process, which can produce dangerous waste and air pollution if not dealt with correctly.

Lastly, Cline fears that rental services will increase our, desire for fast fashion, simply because it’s so easy to get. There’s something called ‘share-washing’ that leads to more wasteful behaviors mainly because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as “a way to share rides and limit car ownership,” and yet “it has been proven to discourage walking, bicycling, and public transportation use.”

Renting clothes is still preferable to buying them cheap and throwing them in the waste after a few wears, but we shouldn’t let the convenience of these services make us satisfied. There’s an even better step—and that’s wearing what is already in the closet (衣柜).

1.How much carbon will be produced when an item is normally ordered online and then returned?

A.10 kilograms. B.20 kilograms.

C.40 kilograms. D.50 kilograms.

2.What does Elizabeth Cline think of clothing rental?

A.It is considered fashioned.

B.It is popular to young people.

C.It can reduce transport burden.

D.It can leave large carbon footprint.

3.The example of Uber is used to show the rental services ________.

A.cause more wasteful behaviors

B.satisfy our desire for fashion

C.help protect the environment

D.replace the public transport

4.What does the author actually want to express in the last paragraph?

A.The request for throwing cheap clothes.

B.The advice on wearing what we own.

C.The disadvantage of clothing rental.

D.The call for renting clothes.

    What were you like as a teenager? I was a nightmare. I was rude to my parents, always stayed out late, never did my homework, hung out with the wrong people and made lots of bad decisions. Obviously, this is the age when teenagers are out of control and behave badly. Maybe, if you’re a teenager now, you think this is unfair judgment or it’s not your fault. Well, you might be right!

Experts have found that it’s a teenager’s brain that is to blame. Between the ages of about 13 to 19 — a period known as adolescence, the brain is still developing in areas that control behavior. This has an influence on learning and multitasking, stress and memory, sleep, and decision-making. For parents, these results often make them notice lots of behaviors that they may have earlier blamed on hormones (荷尔蒙) or just moodiness.

So our brains are still developing much later than it was thought before. Is this the perfect excuse for teenagers to walk around aimlessly and not get their homework done on time? Of course not! According to Professor Sarah-Jayne Blakemore, who made the new discovery, it’s to do with our prefrontal cortex that’s the part of our brain right at the front, just behind the forehead. She says “It takes part in a whole area of very high-level cognitive (认知的) tasks such as decision making and planning — we know that this area is going through very large amounts of development during the adolescent years”. This is the part of the brain which plays an important role in planning, and, for a teenager, this hasn’t developed yet. So getting organised to do their homework, for example, can come as a bit of challenge.

I wish I’d known about this because instead of telling my teacher I’d left my homework on the bus or that the dog had eaten it. Now I could say, “Sorry sir, my brain isn’t developed enough for the cognitive task of planning my homework.”

1.Which of the following is common in teenagers?

A.Doing some bad deeds.

B.Being blamed for their age.

C.Stopping their brain development.

D.Making excuses for their bad behaviors.

2.What do we know about the new discovery?

A.The brain develops in the first few years of life.

B.The forehead stops developing during adolescence.

C.Hormones take responsibility for teenagers’ behaviors.

D.The prefrontal cortex affects us performing cognitive tasks.

3.What is the best title for the text?

A.Behind the adolescence

B.Inside a Teenager’s Brain

C.For the Naughty Teenagers

D.About the brain Development
