  The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class.In the past 15 years,   1   have reported well over 100   2   that could have been caused by electromagnetic interference.The   3   of this interference remains unconfirmed,   4   increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radios and cassette players and mobile telephones.

  RTCA, an organization which   5   the aviation industry, has recommended that   6   airlines ban such electronic devices from being used   7   “critical” stages of flight,   8   take-off and landing.Some experts have gone further,   9   for a total ban during all flights.Currently, rules on using these devices are   10   up to individual airlines.And although some airlines prohibit passengers from   11   such equipment during take-off and landing, most are reluctant to enforce a total ban.Many passengers want to work during flights.

  The   12   is predicting how electromagnetic fields   13   affect an aircraft’s computers.Experts   14   that portable devices emit radiation, which affects those wavelengths which   15   use for navigation and communication.But, they have not been able to   16   these effects in a laboratory, they have no   17   of knowing whether the interference might be   18   or not.

  The fact that aircraft may be vulnerable(易受攻击)to interference   19   the risk that terrorist may use radio system in order to   20   navigation equipment.

阅读下面的短文,请根据短文后的要求答题(请注意问题后的词数要求)。

[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.

  [2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生虫引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (输送) to the immune system to fight the infection.

  [3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.

  [4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

1.What is the main idea of the text?(no more than 10 words)

________________________________________________________________________

2.Complete the following statement with proper words.(no more than 4 words)

Those countries that have the ________________ are always at the bottom of the IQ list.

3.Fill in the blank in Paragraph 2 with proper words.(no more than 5 words)

___________                                                                

4.What can cause intelligence difference?(no more than 8 words)

______________________________________________________________________

5.What does the word “they” (Line2, paragraph3)probably refer to? (no more than 8 words)

Ⅲ.Reading Comprehension
Section A
Some personal characteristics play an important role in the development of one’s intelligence.But people fail to realize the importance of training these factors in young people.
The so-called “non-intelligence factors” include one’s feelings, will, motivation, interests and habits.After a 30-year follow up study of 8,000 males, American psychologists50that the main cause of disparities in intelligence is not intelligence51      , but non-intelligence factors including the desire to learn, will power and self-confidence.
52people all know that one should have definite objectives, a strong will and good learning habits, quite a number of teachers and parents don’t pay much attention to      53     these factors.
Some parents are greatly worried when their children fail to do well in their studies.They blame either genetic factors, malnutrition(营养不良) or laziness, but they never take54consideration these non-intelligence factors.At the same time, some teachers don’t inquire into these, as reasons55students do poorly.They simply give them more courses and exercises, or56     criticize or laugh at them.After all, these students lose self-confidence.Some of them just feel defeated and57themselves up as hopeless.Others may go astray(堕落)because they are sick of learning.An investigation of more than 1,000 middle school students in Shanghai showed that 46.5 percent of them were58of learning, because of examinations, 36.4 percent lacked persistence, initiative and consciousness and 10.3 percent were sick of learning.
It is clear that the lack of cultivation of non-intelligence factors has been a main      59
to intelligence development in teenagers.It even causes an imbalance between physiological and  60  development among a few students.
If we don’t start now to61the cultivation of non-intelligence factors, it will not only affect the development of the intelligence of teenagers, but also affect the quality of a whole generation.Some experts have put forward62about how to cultivate students’ non-intelligence factors.
First, parents and teachers should63understand teenage psychology.On this basis, they can help them to pursue the objectives of learning,      64their interests and toughening their willpower.
