下列有关借款费用的会计处理，不正确的是( )。
为购建或者生产符合资本化条件的资产而借入专门借款的，其利息费用资本化金额 应当以专门借款当期实际发生的利息费用，减去将尚未动用的借款金额存入银行取得的利息收入或者进行暂时性投资取得的投资收益后的金额确定
符合借款费用资本化条件的存货包括：房地产开发企业开发的用于出售的商品房 机械制造企业制造的用于对外出售的大型机械设备等，这些存货需要经过相当长时间的建造或者生产活动，才能达到预定可销售状态
专门借款产生的汇兑差额只有在资本化期间内才能予以资本化；而专门借款辅助费 用只要在购建或者生产符合资本化条件的资产达到预定可使用或者可销售状态之前发生的，发生时均可资本化
专门借款发生的利息费用，在资本化期间内，应当全部计入符合资本化条件的资产成本，但仍需要计算借款资本化率

请阅读 Passage 1,完成第 21~25小题 。
Passage 1
First two hours, now three hours-this ishow far in advance authorities are recommending people show up to catch adomestic flight, at least at some major U.S. airports with increasingly massivesecurity lines.
Americans are willing to toleratetime-consuming security procedures in return for increased safety. The crash ofEgyptAir Flight 804, which terrorists may have downed over the Mediterranean Sea,provides another tragic reminder of why. But demanding too much of airtravelers or providing too little security in return undermines public supportfor the process. And it should: Wasted time is a drag on Americans ' economicand private lives, not to mention infuriating.
Last year, the Transportation SecurityAdministration (TSA) found in a secret check that undercover investigators wereable to sneak weapons-both fake and real-past airport security nearly everytime they tried. Enhanced security measures since then, combined with a rise inairline travel due to the improving economy and low oil prices, have resultedin long waits at major airports such as Chicago ' s O ' Hare International. Itis not yet clear how much more effective airline security has become-but thelines are obvious.
Part of the issue is that the governmentdid not anticipate the steep increase in airline travel, so the TSA is nowrushing to get new screeners on the line. Part of the issue is that airportshave only so much room for screening lanes. Another factor may be that morepeople are trying to overpack their carry-on bags to avoid checked-baggagefees, though the airlines strongly dispute this.
There is one step the TSA could take thatwould not require remodeling airports or rushing to hire: Enroll more people inthe PreCheck program. PreCheck is supposed to be a win-win for travelers andthe TSA. Passengers who pass a background check are eligible to use expectedscreening lanes. This allows the TSA to focus. on travelers who are higherrisk, saving time for everyone involved. The TSA wants to enroll 25 millionpeople in PreCheck.
Ithas not gotten anywhere close to that, and one big reason is sticker shock:Passengers must pay $85 every five years to process their background checks.Since the beginning, this price tag has been PreCheck ' s fatal flaw. Upcomingreforms might bring the price to a more reasonable level. But Congress shouldlook into doing so directly, by helping to finance PreCheck enrollment or tocut costs in other ways.
The word "expedited" (Para. 5) is closest in meaning to______.
quieter
