video posted to her Twitter account. "If you've been on a White House tour, chances are
that you may have seen this sign," she said holding up a piece of paper. "Well, not any
more," she said smiling as she tore the sign apart, which had been displayed during tour
hours。
    The White House said in a statement, "Guests are now welcome to take photos
throughout the White House tour route and keep those memories for a lifetime." The
long-standing ban ends on July 1st, and from that point on guests will be able to start

cameras with a lens（镜头）of three inches or less.
    But the White House warns that visitors must ensure that their photography doesn't
interrupt the enjoyment of other guests on the tour. While it gives no specific reason for
the sudden change, there are still a few things that guests are not permitted to do. For

      Many people today do not enjoy grocery shopping, but the experience we have is still
many times better than that of the past.
     Gone are the days when consumers paid higher prices for the advantage of a painfully
slow shopping experience. In addition to lower prices, supermarkets also offer shoppers
added convenience and much quicker service.
   In the old days, grocery shopping was quite a bit troublesome. Consumer-sized
packages did not exist, so a clerk had to measure out the exact amount you needed for
everything you bought. This system cost much labor and therefore was rather expensive.
On top of that, the entire experience was extremely time-consuming as, much like buying
meat at a butcher shop, the number of shoppers that a store could serve at the same time
was limited by the size of its staff. The high labor costs and poor efficiency (效率) were
quite a problem for both the industry and its public.
    The supermarket is a large departmentalized retail store, offering "one-stop shop"
convenience with housewares , magazines, beauty products, and much more in addition to
the food items sold by traditional stores. Need soap to go with your newspaper and bread?
The supermarket saves you time by providing all three items under one roof. Along with
added convenience comes added efficiency.
     Shoppers can now fetch what they want from shelves instead of waiting for service.
This in turn reduces the need for additional staff, helping owners to cut costs greatly and
to pass the savings back to the consumer. In fact, supermarkets pass so much of the
savings back that their margins are razor-thin - only l to 3 percent - so to make a profit,
they must rely on extremely high turnover rates and keeping operating expenses low, for
example, by not offering delivery for one. The result is a quick and painless shopping
experience with very reasonable prices.
24. Which of the following is listed as a disadvantage of traditional grocery stores?
     A.  Fewer staff members.              B. Less shopping time.
     C. Smaller trading profits.              D. Higher operating costs.

     A. savings            B. prices               C, profits             D. expenses

    A.  they want to keep costs down      B.  it isn't a good way to attract consumers
    C. there is no demand for such a service  D. it's the major cause of low efficiency
