[不定项选择题]资料：Singapore Airlines plans to introduce inflight mobile phone and internet access in May this year,beginning with its flagship Airbus A380 fleet.
Several pricing models are believed to be under consideration,beginning with a low-cost package suitable for WE—service such as Google Gmail,Yahoo and Hotmail as well as a 30MB allowance for around SGD$25 （that's $20 Russia and US,and ￡20 and ￡ 14）.
The airline is polling selected members of its KrisFlyer frequent flyer loyalty program to participate in an online survey about your attitudes towards inflight mobile and internet services,which we are planning to introduce from May 2011 according to the email invitation.
The survey asks travellers for their opinions on pricing packages such as SGD$25 for 30MB,as well as if mobile phone cells and SMS messages should be permitted.
Should passagers be allowed to make and take calls at 30000 feet they'll pay plenty for the privilege, with calls being charged at international roaming rates.
As it's up to each country to decide what those rates are-and with Singapore Airlines effectively being its own country in terms of providing a fully controlled and self-contained telecoms system on board each plane-those rates could literally be sky high.
SQ's inflight internet and mobile service, which may carry the KrisNet brand in keeping with the KrisWorld inflight entertainment system, is expected to debut on the Airbus A380 before being installed onto the airline's A340-500 and Boeing 777-300ER aircraft.
Passagers will be able to access the internet on any device from a smart phone to a tablet or laptop, as Singapore Airlines will support connections through both Wifi wireless networking （using a series of low-hotpots located throughout the plane） and 3G（via tiny pico-cell stations）.
It will employ the pepular OnAir technology, jointly developed by IT company SITA and Airbus,and currently used by over 20 airlines（including Air New Zealand's current
trial of in-flight internet） which feeds the Wifi and 3G signals through to Inmarsat's SwiftBroadband satellite network.
Which of the following may be the best title for the passage?
A.Singapore Airlines to charge high international roaming rates
B.Singapore Airlines to offer different pricing models for inflight mobile and Internet services
C.Singapore Airlines to unveil sky high net
D.Singapore Airlines to conduct online survey

[单项选择]In the same way that a child must be able to move his arms and legs before he can learn to walk, the child must physiologically be capable of producing and experiencing particular emotions before these emotions can be modified through learning. Psychologists have found that there arc two basic processes by which learning takes place. One kind of learning is called’" classical conditioning." This occurs when one event or stimulus is continuously followed by a reward or punishment. It is through classical conditioning that a child learns to associate his mother’s face and voice with happiness and love, for he learns that this person provides food and comfort. Negative emotions are learned in a similar fashion.
The second kind of learning is called "operant (动作的) conditioning. "This occurs when an individual learns to do things that produce rewards in his environment and learns not to do things that produce punishments. For example, if a mother always attends to her baby when he crie
