    The biggest safety threat facing airlines today may not be a terrorist (恐布分子) with
a gun, but the man with the portable computer in business class. In the last 15 years,
pilots have reported well over 100 incidents that could have been caused by electromagnetic
(电磁) interference (干扰). The source of this interference remains unconfirmed, but
increasingly, experts are pointing the blame at portable electronic device such as portable
computers, radio and cassette players and mobile telephones.
    RTCA, an organization which advises the aviation (航空) industry, has recommended that
all airlines ban (禁止) such devices from being used during "critical" stages of flight,
particularly take-off and landing. Some experts have gone further, calling for a total ban
during all flights. Currently, rules on using these devices are left up to individual
airlines. And although some airlines prohibit (禁止) passengers from using such equipment
during take-off and landing, most are reluctant to enforce a total ban, given that many
passengers want to work during flights.
   The difficulty is prediction how electromagnetic fields might affect an aircraft's
computers. Experts know that portable device emit radiation which affects those wavelengths
which aircraft use for navigation and communication. But, because they have not been able
to reproduce these effects in a laboratory, they have no way of knowing whether the
interference might be dangerous or not.
    The fact that aircraft may be vulnerable (易受损的) to interference raises the risk
that terrorists may use radio systems in order to damage navigation equipment. As worrying,
though, is the passenger who can't hear the instructions to turn off his radio because the
music is too loud.

1. The passage is mainly about _____.

[ ]

A. effective safety measure of aircraft crashes
B. a possible cause for air flight accidents
C. the defects (缺点) of electronic devices
D. a new regulation for all airlines

2. What is said about the over 100 aircraft incidents in the past 15 years?

[ ]

A. They may have taken place during take-off and landing.
B. They may have been caused by the damage to the radio systems.
C. They were suspected to have resulted from electromagnetic interference.
D. They were proved to have been caused by the passengers' portable computers.

3. Few airlines want to impose (强加) a total ban on their passengers using electronic
devices because _____.

[ ]

A. they have other effective safety measures to fall back on
B. they don't believe there is such a danger as radio interference
C. the harmful effect of electromagnetic interference is yet to be proved
D. most passengers refuse to take a plane which bans the use of radio and cassette players

4. Why is it difficult to predict the possible effects of electromagnetic fields on an
airplane's computers?

[ ]

A. Because experts lack adequate equipment to d such research.
B. Because it is extremely dangerous to conduct such research on an airplane.
C. Because it remains a mystery what wavelengths are liable to e interfered with.
D. Because research scientists have not been able to produce the same effects in labs.

5. It can be inferred from the passage that the author _____.

[ ]

A. hasn't formed his own pinion on this problem
B. has overestimated the danger of electromagnetic interference
C. thinks it is unreasonable to exercise a total ban during flight
D. is in favor of prohibiting passengers' use of electronic devices completely

The National Outline for Medium and Long Term Education Reform and Development (2010 - 20) was released over the weekend. Here are some of the highlights:
Four – percent effort
The government says spending on education will be 4 percent of GDP by 2012. globally, average spending on education is about 4.5% of GDP. China spend 3,33% in 2008. according to Hu Angang, of Tsinghua University’s Center for China Studies, even if China reaches that goal, it will only rank about 100 th out of 188 countries.
Administrative rank
Administrative rankings for school leaders are to be phased out to tackle the bureaucracy (官僚机构) problem that limits educational development, according to Cheng Fangping, of the national Institute for Educational Research. Areas like teaching programs, scientific research, and technological development will be more independent.
Vocational Education
The system will be free of charge. According to Wu Yan, of Beijing Institute of Educational Sciences, this will be key to developing China’s production capacity and will improve poor people’s lives dramatically.
Entering college
Universities could eventually have the freedom to choose some of their own high school applicants. Normally, students are accepted based on the uniform national exam scores. Also, students who agree to go to a remote area could be admitted to university under special circumstances. The most likely change could come on the college entrance English test, which might be modeled on the IELTS or TOEFL. Students will be able to take it several times and pick their best score.
56．Which of the following is true in the future according to the passage?
A．Applicants could take the IELTS or TOEFL instead of the college entrance English test.
B．Colleges will be given the right to choose all of their own applicants.
C．Vocational education will be party free to make people’s lives better.
D．Applicants could sit for the college entrance English test more than once.
57．Which of the following words is closest in meaning to “uniform” in the last paragraph?
A．formal B．official C．same D．united
58．We can learn from the passage even though our country spends 4% of GDP on education in 2012, ________.
A．there will still be 188 countries ahead of China in this aspect
B．China will certainly overtake the global average spending on education
C．there might be nearly 100 countries ahead of China in this aspect
D．China will be the 100 th country to spend over the global average on education
59．From the third paragraph, we can infer that________.
A．school leaders will have more freedom to manage the school
B．schools will have more limits from the government
C．School administrative rankings are to be strengthened to solve the bureaucracy problem
D．schools and research centers will be fully independent from the government

Being interested in a theme park since the time that I was a child, I have learned a thing or two over the years about packing for a day of fun. A trip to a theme park is always a adventure, but if you’re not prepared, your day of fun could easily turn into a tiny little nightmare(噩梦). It is important to pack long sleeved(带袖的) shirts or jackets for all members of your family. I is also a good idea to pack an extra pair of socks for each member of the family, especially the children, as those wonderful water rides can be fun, but wet socks that won’t dry aren’t so much fun.

You don’t want to pack too much food, as you will probably want to experience at least some of the food offered at the theme park of your choice(that’s half of the fun), but it’s always a good idea to bring some energy increasing snacks, such as fruit,trail mix,etc. This can mean the difference between spending a lot of money on snacks or a little money on one or two good meals.

Theme parks,while fun and exciting, can wear a person out,especially a child, so it’s important to keep hydrated(含水的). I would suggest packing one bottle of water per person, and possibly a couple of cans of soda or bottles of juice as well.

It’s a good idea to have at least two cell phones or even a set of “walkie-talkies” in the event that your family gets,separated in the park. It’s a good idea to give one of these things to the children and one to the parents and make sure that each of them knows how to use it. This could be the difference between trouble and a happy ending,

1.You should get well prepared before going to a theme park__________.

A. because the trip always costs much money

B.because there are always too many people in a theme park.

C. so as not to suffer from bad dreams when going back

D.so as to cut down your trip expenses and have more fun

2.From the passage, we can know_______________.

A.the author was fond of visiting theme parks when he was a child

B.wearing wet socks in a theme park will bring children much fun

C.it is terrible to have a taste of the food offered in a theme park.

D. we’d better bring enough food, clothing and water when going to a theme park

3.What does th underlined part”walkie-talkies” in the last paragraph probably refer to?

A. A kind of transportation tool B.A kind of musical instrument

C.A kind of CDplayer D.A kind of phone

4.How many types of things does the author advise us to pack for day trips to a theme park?

A Three B.Five C.Six D. Eight

      Advertising is a form of communication that uses all kinds of media, and is visible
everywhere these days. Typical customers of advertising companies are other companies,
or businessmen, who want to persuade potential customers to buy more of what they
make or sell. But there are other kinds of customers. Some organizations spend large
sums of money on advertising a political party or other group that sells what is not, strictly
speaking, a product or service. Such non - profit organizations are not typical advertising
customers, and they prefer ways of spreading knowledge, changing attitudes, and
improving society.
     Many advertisements are designed to increase sales of products and services by either
improving brand image or, in the case of non - profit organizations, expressing ideas. In
order to achieve th~s, advertisements will often pass on truthful information while delivering
their messages. Every major medium is a means of delivering these messages, including
television, radio, cinema, magazines, newspapers, video games, the Internet and billboards
(大幅广告牌). Advertising will usually be created and. placed by an advertising agency
on behalf of company or other organization.
     Spending on advertising has increased greatly in recent years. In 2006, spending was
estimated at $155 billion in the United States and $385 billion worldwide; the latter is
expected to reach more than $500 billion by 2010.
     While advertising can be seen as a necessity for economic growth and social
development, it is not without social costs. Advertisement emails and other forms of junk
mail have become so popular that ~they have become a major burden to users of I
nternet email services, as well as a financial burden on Internet email service providers.

Title: 1. _______
2. ______	●For- profit organizations, such as other companies and businessmen ●3. _____ organizations including 4. ____ parties and other interest groups
Purposes	●Persuade 5. ____ customers and 6. ____ sales ●Spread knowledge ●Change attitudes ●Improve society
