Ashcombe Primary School in WestonsuperMare, Somerset, has told parents that cards declaring love
can be "confusing" for children under the age of 11, who are still emotionally and socially developing.
In his February newsletter (简讯), Peter Turner,head teacher, warned that any cards found in school
would be confiscated.
He wrote, "We do not wish to see any Valentine"s Day cards in school this year. Some children and
parents encourage a lot of talks about boyfriends and girlfriends."
"We believe that such ideas should wait until children are mature enough emotionally and socially to
understand the commitment involved in having or being a boyfriend or girlfriend."
Mr. Turner said any families wanting to support the Valentine"s Day concept should send cards in the
post or deliver them to home addresses by hand.
His views were supported by Ruth Rice, 46, who has twins Harriet and Olivia,9,at the school.
She said, "Children at that age shouldn"t really be thinking about Valentine"s Day, and they should be
concentrating on their schoolwork."
"They are at an age when they are easily influenced and most parents including myself are with
Mr. Turner."
She added, "The cards caused too much competition. If someone gets a card and another doesn"t then he will be disappointed."
However, Rajeev Takyar, 40, who sells newspapers and has two children Jai, 11, and Aryan, 5, at the school, said he was "genuinely outraged"．
He said, "There are schools that have banned conkers (康克戏) and snowballs, and now Valentine"s
Day cards."
"I think banning the cards stops children from having social skills. How are they going to learn about relationships otherwise? It"s ridiculous."
Alec Suttenwood, founder of the AntiPolitical Correctness Group, said of the ban, "It"s totally
ridiculous. Young children just send the cards to each other as friends and to their parents. It"s just a bit of harmless fun. There is no difference between this and Mother"s or Father"s Day."
B. teachers haven"t taught them how to make friends
C. children shouldn"t learn about social relationships
D. students talk too much about boyfriends and girlfriends
B. destroyed
C. taken away
D. burnt away
B. children should focus their mind on their lessons
C. sending holiday cards waste both time and money
D. making friends has a negative influence on children
B. Children should learn how to develop social skills.
C. English schools don"t allow students to play games.
D. Some parents think it unreasonable to ban the cards.
B. Shall We Send Valentine"s Day Cards?
C. Different Opinions on Valentine"s Day Cards
D. Parents" Concern about Valentine"s Day Cards
is only mildly annoying. On a cellphone, it could make you want to skip the purchase entirely.
This is why investors, startups (初创企业) and major corporations are pouring money into services
that make it easier to use cellphones to buy goods and transfer money. The aim is to turn phones into
virtual credit cards or checkbooks, enabling the kind of clickandbuy commerce and online banking that
people have come to expect on their PCs. But shrinking down (缩小) those services presents serious
challenges.
The services must work on many different phones and through many cellphone service providers,
which usually control the billing relationships with customers. That adds complexity to the already tricky
business of safely and securely transferring funds among financial institutions and merchants.
Mobile payment systems have been tried before, with only modest success. Driving a new flurry (一
阵兴奋) of deal making, industry analysts and executives say, is the success of the iPhone, BlackBerry
and other sophisticated (尖端的) devices. These phones make complex interactions easier.
Now the race is on to develop new payment systems-and to get several percentage points in fees
from each transaction. They"re seeing that returns could be so huge. Obopay, a startup that lets people
transmit money to one another via text message, raised $ 35 million from Nokia"s investment. Also, a
mobile payments startup called Boku announced that it had received $ 13 million in venture capital
financing.
When people can use their phone numbers to make a purchase, they are 10 times as likely to follow
through on a transaction as when they have to type in credit card and billing information, said David
Marcus, chief executive of a startup called Zong.
Mobile payment companies also need to get cooperation from merchants, which must add a payment
option to their mobile sites or applications.
But the potential opportunity to get fees from the growing number of mobile transactions is too__

C. three
D. four

C. troublesome
D. impossible
B. Too difficult to seize.
C. Too heavy to lift.

still prefer lowtech ways of doing things. Here"s an example of why this is happening. You can
microwave a frozen hamburger in 60 seconds. However, it won"t taste as good as the one you cook
on the stove. And if you"re in that much of a hurry, you probably won"t take time to toast the bun.
Hightech cooking saves time, but it doesn"t make bettertasting meals.
Most people get their news from hightech sources like television or the Internet. This has many
advantages. For example, electronic news is more up to date than newspapers or magazines. It"s also
more exciting to see live and videotaped news events than photographs. However, newspapers and
magazines have some important advantages. They give more background and details. They also let
you read the parts that are important to you and skip the rest.
Other hightech timesavers have similar disadvantages. For example, most people use the phone
or email to stay in touch with friends and family members who live in other places. But when you use
the Internet or the phone, you don"t always think carefully about what you are saying, and sometimes
you forget the important things you want to communicate. Similarly, when you wordprocess a
homework assignment instead of handwriting it, you can check your spelling electronically and put in
fancy headings. However, some students are so busy with the computer that they don"t pay enough
attention to the actual words they are writing.
B. Lowtech cooking produces bettertasting meals.
C. Hightech news programs always keep you reading what is important to you.
D. Handwritten homework is better than wordprocessed homework.
B. Easy come, easy go.
C. Every coin has two sides.
D. Learn to walk before you run.
B. Advantages vs disadvantages.
C. Newspapers and magazines vs television and the Internet.
D. Wordprocessing vs handwriting.
B. Opinion-Discussion-Description.
C. Topic-Comparison-Supporting examples.
D. Introduction-Supporting examples-Discussion.
allow them to walk again. Newts (蝾螈)in the same situation, on the other hand, can grow limbs back
their own! Scientists have known for a long time that certain animals can regrow limbs, but they haven"t
quite figured out how these creatures do it.
Researchers have now come up with some new ideas. Their work may give people the ability to
regrow lost limbs. The researchers started with two simple experiments: when you cut a newt"s leg at
the ankle, only the foot grows back; when you cut off a leg at the very end, the whole leg grows back.
In both cases, the regrowth begins with stem cells. Stem cells can develop into nearly any type of cell
in the body.
How do a newt"s stem cells know when to grow only a foot and when to regrow a whole leg?
This question relates to another mystery. In newt"s, a cutoff leg will grow back only if the nerve
bundle(神经束) in it also grows back, but if something prevents the nerve bundle from growing the
stem cells at the wound won"t regrow a new leg.
In its study, a British team focused on a protein called nAG. When the team prevented nerves in
a limb from growing, but added the nAG protein to stem cells in the limb, the limb still regrew. That
protein seems to guide limb regrowth. People have proteins that are similar to nAG. Further research
into these__materials may someday help human limbs recover by themselves.
B. its leg was cut off and the nerve bundle stopped growing
C. its leg was cut off and the nerve bundle could grow back
D. its ankle and the nerve bundle could grow back
B. Proteins similar to nAG.
C. Stem cells and proteins.
D. Stem cells and nerve bundles.
B. shows where researchers got their new ideas
C. states the author"s opinion
D. describes the result of researchers" studies
B. To find out the similarity between human and newts.
C. To find out what is nAG.
D. To find a way of helping human limbs recover by themselves.

_1_ These selections provide practice on employing different reading skills to get the message of the
writer. They also give students practice in four basic reading skills:skimming, scanning, reading for
thorough comprehension, and critical reading.
Skimming involves reading quickly through a text to get an overall idea of its contents. This kind of
rapid reading is suitable when you are trying to decide if careful reading is desirable or __2__
Like skimming, scanning is also quick reading. However, in this case the search is more concentrated.
__3__ When you read to find a particular date or number, you are scanning.
Reading for thorough comprehension is carefully reading in order to understand the total meaning of
the passage. At this level of comprehension the reader is able to summarize the author"s ideas _4_.
Critical reading demands that a reader makes judgments about what he or she reads. This kind of
reading requires posting and answering questions such as "_5_", "Do I share the author"s point of view?"
and "Am I convinced by the author"s arguments and evidence?
A. Does my own experience support that of the author?
B. Reader"s Choice is one of the most popular magazines in the world.
C. but has not yet made a critical evaluation of those ideas.
D. The book contains many types of selections on a wide variety of topics.
E. To scan is to read quickly in order to find out specific information.
F. Do I know about the author?
G. when there is no time to read something carefully.
