If you think that Internet shopping on a Sunday gets you the best deals,then think again.Tuesday is actually the best day of the week if you want to grab a bargain,according to an exhaustive analysis of on-line shopping.Thursday is the second best day followed by Friday-but Sunday is when you are least likely to make a saving.
The study also looked at months and found that the pre-Christmas rush in November is when there are most bargains around on the web-and not the January sales.US retailer(零售商) reporting service Sum All examined 3,000 companies and half a billion transactions(交易) as part of its report.It worked out the average discount(折扣) offered to consumers on each day of the week and over different times of the year.
The best day of the week was Tuesday where savings were 4.81 percent,followed by Thursday on 4.80 percent.In third place was Friday at 4.65 percent,then Wednesday at 4.13 percent and Monday at 4.11 percent.Only the foolish would shop on a Saturday where the discounts were typically 3.84 percent-and Sunday was the worst with 3.37 percent.
The analysis by month is even more surprising as most people think that waiting until the post-Christmas sales would yield the biggest discounts.In fact,November is when you will get the largest savings at 5.99 percent on average.January came in second at 4.95 percent,followed by May at 4.50 percent.
The worst month to buy online was March where you could expect to save just 2.76 percent.Consumers and experts have been speculating for years about the best time to shop online.
Booking a flight has almost become a science with some claiming that buying six weeks before you travel guarantees you the best price.However,a recent analysis by the US Airlines Reporting Commission found that was not actually the case.
Not only did the six-week window fail to pile up,in some cases the best fares were on sale as long as 24 weeks before departure.The ARC said that booking well in advance is best advised for busy routes or long haul flights(長(zhǎng)途航班),as the price only tends to go up.

1.All routes to STEM (science,technology,engineering and mathematics) degrees run through calculus (微積分) classes.Each year,thousands of college students take introductory calculus.But only a small number ultimately complete a STEM degree,and research about why students abandon such degrees suggests that traditional calculus courses are one of the reasons.With scientific understanding and innovation increasingly central to solving 21st-century problems,this loss of talent is something society can ill afford.
Math departments alone are unlikely to solve this dilemma.Several of the promising calculus reforms were spearheaded by professors outside of math departments.STEM faculty are prioritizing cooperation across disciplines to transform math classes to cultivate a diverse generation of STEM researchers and professionals.
This is not uncharted territory.In 2013,life sciences faculty at the University of California,Los Angeles,developed a two-course sequence that covers classic calculus topics,but also emphasizes their application in a biological context.Creating this course,Mathematics for Life Scientists,wasn't easy.The life sciences faculty involved,none of whom had a joint appointment with the math department,said they turned to designing the course themselves after math faculty rejected their request for cooperation.
In Ohio,Wright State University's Engineering departments also revised math offerings.Rather than changing the content of the calculus course,they focused on preparing students for calculus by emphasizing "engineering motivation for math." The approach enhanced opportunities for students with weaker math backgrounds to succeed in engineering and doubled the average graduation rate of engineering students without reducing the average grade of graduates.Math learning is fundamental to all STEM fields,but the opposite also appears to be true.
(1)What problem is mentioned in paragraph 1?
A.Increasing STEM dropout rate.
B.The reform of calculus courses.
C.Shrinking admission to STEM majors.
D.The shaken belief in the role of calculus.
(2)What does "spearheaded" in paragraph 2 probably mean?
A.challenged
B.evaluated
C.cancelled
D.initiated
(3)What do we know about the calculus course reform according to the text?
A.STEM departments made calculus content easier to improve students' grades.
B.Math departments sought cooperation with STEM counterparts to urge reforms.
C.Placing calculus learning in specific STEM contexts is a workable approach.
D.Removing calculus is the key to increasing graduation rate of STEM students.
(4)What does "the opposite" in the last paragraph refer to?
A.The STEM fields may be the foundation of other science subjects.
B.The STEM fields may be central to making math learning effective.
C.Math learning may set barrier for science study in the STEM fields.
D.Math learning may make way for science study in the STEM fields.發(fā)布:2025/1/1 17:30:2組卷:23引用:3難度:0.5 -
2.I once thought that outer beauty is the only factor to become a great person.When I was young,I read many kinds of books,most of which described characters who are handsome or beautiful.So I think that being beautiful is the only way to become a success.
As I grew up,the story of my best friend made me realize that outer beauty was not so important to make a person successful.She is so beautiful a girl that every classmate liked to chat with her,but she was very arrogant(傲慢).In her opinion,she could get all she wanted because of her beauty,but all of her friends left her one by one!Only then did she come to know the importance of the beauty in a person's heart,which changed her attitude and she made friends again.
Turning on TV,we can see many advertisements,most of which seem to give us a feeling that,physical attractiveness is the most important thing. There seems to be a boom in plastic surgery.It is surprising that more and more people,especially girls and women,try it like the first man-made beauty in China,Hao Lulu.It is a common sense that attractive people can easily find work.Most good-looking guys,usually get higher scores in the job interviews.But what is real beauty?I want to say that is inner beauty because those who have beauty in their soul are really beautiful persons.
As is known,the beauty judged with eyes is temporary,so we should concentrate on inner beauty.And if we make the efforts to make our minds beautiful,we'll live a happier life.
(1)Why did the author want to have a good appearance when she was young?

D.Those who have good appearances should also develop the beauty in their hearts.發(fā)布:2025/1/1 18:0:1組卷:12引用:2難度:0.6 -
3.You run into the grocery store to quickly pick up your item.You grab what you need and head to the front of the store.After quickly sizing up the check-out lines,you choose the one that looks fastest.You chose wrong.People getting in other lines long after you have already checked out and headed to the parking lot.Why does this seem to always happen to you?
Well,as it turns out,it's just math that is working against you.A grocery store tries to have enough employees at the checkout lines to get all their customers through with minimum delay.But sometimes,like on a Sunday afternoon,they get super busy.Because most grocery stores don't have the physical space to add more checkout lines,their system becomes overburdened.Some small interruption - a price check,a particularly talkative customer---will have downstream effects,holding up the entire line behind them.
If there are three lines at the store,these delays will happen randomly at different registers(收銀臺(tái)).Think about the probability.The chances of your line being that fastest one are only one in three,which means you have a two-thirds chance of not being in the fastest line.So it's not just in your mind:Another line is probably moving faster than yours.
Now,mathematicians have come up with a good solution,which they call queuing theory,to this problem:Just make all customers stand in one long snaking line,called a serpentine line,and serve each person at the front with the next available register.With three registers,this method is about three times faster on average than the more traditional approach.This is what they do at most banks,Trader Joe's,and some fast-food places.With a serpentine line,a long delay at one register won't unfairly punish the people who lined up behind it.Instead,it will slow everyone down a little bit.
(1)What phenomenon is described in the first paragraph?
A.Queuing in a line.
B.A shopping experience.
C.A rush in the morning.
D.Cutting in a line.
(2)According to the article,what may cause delays in checking out?
A.The lack of employees in the grocery store.
B.Some unexpected delays of certain customers.
C.The increasing items bought by customers.
D.A worsening shopping system of the store.
(3)What is the solution given by mathematicians?
A.Employing more workers for checking out.
B.Limiting the number of queuing people.
C.Making only one line available.
D.Always standing in the same line.
(4)What's the principle behind the queuing theory?
A.To pursue the maximum benefit.
B.To leave success or failure to luck.
C.To avoid the minimum loss.
D.To spread the risk equally among everyone.發(fā)布:2025/1/1 17:30:2組卷:2引用:2難度:0.5
