案情：甲公司从某银行贷款1200万元，以自有房产设定抵押，并办理了抵押登记。经书面协议，乙公司以其价值200万元的现有的以及将有的生产设备、原材料、半成品、产品为甲公司的贷款设定抵押，没有办理抵押登记。后甲公司届期无力清偿贷款，某银行欲行使抵押权。法院拟拍卖甲公司的房产。甲公司为了留住房产，与丙公司达成备忘录，约定：“由丙公司参与竞买，价款由甲公司支付，房产产权归甲公司。”丙公司依法参加竞买，以1000万元竞买成功。甲公司将从子公司筹得的1000万元交给丙公司，丙公司将这1000万元交给了法院。法院依据竞拍结果制作民事裁定书，甲公司据此将房产过户给丙公司。 　　法院裁定书下达次日，甲公司、丙公司与丁公司签约：“甲公司把房产出卖给丁公司，丁公司向甲公司支付1400万元。合同签订后10日内，丁公司应先付给甲公司400万元，尾款待房产过户到丁公司名下之后支付。甲公司如果在合同签订之日起半年之内不能将房产过户到丁公司名下，则丁公司有权解除合同，并请求甲公司支付违约金700万元，甲公司和丙公司对合同的履行承担连带责任。” 　　在甲公司、丙公司与丁公司签订房产买卖合同的次日，丙公司与戊公司签订了房产买卖合同。丙公司以1500万元的价格将该房产卖给戊公司，尚未办理过户手续。丁公司见状，拒绝履行支付400万元首付款的义务，并请求甲公司先办理房产过户手续，将房产过户到丁公司名下。甲公司则要求丁公司按约定支付400万元房产购置首付款。鉴于各方僵持不下，半年后，丙公司索性把房产过户给戊公司，并拒绝向丁公司承担连带责任。经查，在甲公司、丙公司和丁公司签订合同后，当地房地产市场价格变化不大。 　　问题：

甲公司与丙公司达成的备忘录效力如何？为什么？

What causes traffic jams? Too many cars，right? No! Some Brits are now saying that trafficlights are to blame for much of the congestion.

They suggest that traffic lights be removed at busy roads．They believe people are a better judge of when it’s safe to go，not a traffic light programmed by an absent regulator．

A report from the Institute of Economic Affairs，a UK think tank（智囊团），argues that

abolishing traffic signals would decrease congestion，reduce exhaust（废气）emissions（排放）and improve safety．

The report said that removing lights should also prevent other bad behavior caused by signals．such、as speeding up to catch a green light It would also avoid the wasted time when drivers have to sit at a red light even if no one is using the green

The idea may sound strange，but it’s not new．Seven cities and regions in Europe are experimenting with no-lights roads．

Drachten in the Netherlands has gotten rid of 16 of its traffic light crossings and changed the other two to roundabouts under a“shared space”scheme．At crossings, cyclists dutifully raise their arm when they want to make a turn，and drivers follow a first．arrived，first．through approach and communicate by hand signs，nods and waving．The result? Typical journey time has been cut in half and accidents and congestion have mostly disappeared．

There have been small collisions but no problem，said Hans Monderman，creator of the scheme．“We want small accidents，in order to prevent serious ones．It works well because it’s dangerous．The driver has to be responsible for his or her own risk

“The many rules take away the ability to be considerate”Monderman added．“We’re losing our responsibility for socially responsible behavior．”

So far，Drachten’s locals have called the experiment a success．“I am used to it now，”said Helena Spaanstra．24．“You drive more slowly and carefully．but somehow you seem to get around town quicker．

Tony Ooostward，70，was equally enthusiastic．“I am a walker and now you are the boss at the crossroads，everyone waits for you．But at the same time walkers wait until there are a number of people wanting to cross at the same time．”

Owen Paterson，UK’s Shadow Transport Minister。visited Drachten．He said Britain should learn from the model．“The idea is to create space where there is mild anxiety among everyone so they all behave cautiously．No one drives fast along a busy street thinking that they have right of way．”

The model is being tested in London’s Kensington neighborhood．
