I’m usually fairly doubtful about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago．While any of these statements might be true，they are practically impossible to prove scientifically．Still，I was struck by a report which concluded that today’s children are significantly more anxious than children in the 1950s．In fact，the analysis showed，normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago．

    Why are America’s kids so stressed? According to the report there are two main causes：increasing loneliness--brought on by high divorce rates and little communication with society，among other things--and a growing perception that the world is a more dangerous place．

    Given that we can’t turn the clock back，adults can still do plenty to help the next generation handle such difficulties．At the top of the list is giving children a better appreciation of the limits of individualism．No child is an island．Strengthening social ties helps protect individuals against stress．To help kids build stronger connections with others，you can pull the plug on TVs and computers．Your family will thank you later．They will have more time for face-to-face relationships，and they will get more sleep．

    Limit the amount of virtual violence your children are exposed to．It’s not just video games and movies；children see a lot of murder and crime on the local news．Keep your expectations for your children reasonable．Many highly successful people never attended Harvard or Yale．Make exercise part of your daily routine．It will help you deal with your own anxieties and provide a good model for your kids．Sometimes anxiety is unavoidable．But it doesn’t have to ruin your life．

1．The author thinks that the conclusions of any research comparing people’s state of mind today with people’s state of mind in the past are ________．

      A．surprising              B．confusing             C．interesting              D．questionable

2．What does the author mean when he says，“we can’t turn the clock back”in Paragraph 3?

    A．It’s impossible to slow down the pace of change．

    B．The social reality children are facing cannot be changed．

    C．Lessons learned from the past should not be forgotten．

    D．It’s impossible to forget the past．

3．According to the analysis，compared with normal children today，children treated as mentally ill 50 years ago ________．

      A．had little communication with friends

      B．were probably less self-centered

      C．probably suffered less from anxiety

      D．were considered less individualistic

4．The first and most important thing parents should do to help their children is ________．

      A．to provide the children with a safer environment

    B．to lower their expectations for the children

    C．to get the children more active socially

    D．to set an example for the children to follow

5．What conclusion can be drawn from the passage?

    A．Anxiety，though unavoidable，can be dealt with．

    B．Children’s anxiety has been taken too seriously．

    C．Children’s anxiety can disappear with more parental care．

    D．Anxiety，if properly controlled，may help children become mature．

Passport Control (护照验证处)

    If you are arriving at London Heathrow Airport and are not transferring to another flight outside Britain or Northern Ireland，you must pass through Passport Control and Customs immediately after leaving your plane．If you are not Britain or a citizen of the European Community (欧共体)，you must fill out a special form before your passport is examined．This form is called a landing card and should be given to you during the flight to London．

    After landing, follow the ARRIVALS signs．Make sure you are in the fight channel when you reach Passport Control．There is one channel for holders of European Community Passports，and a second channel marked“Other Passports”．

Baggage Reclaim Area (取行李处)

    After passing through the Passport Control，follow the signs to the Baggage Reclaim Area．If you have luggage which is carried in the aircraft hold，it will be delivered to you in the Baggage Reclaim Area．Look for the sign with your flight number．If you have only hand luggage，go directly through the Baggage Reclaim Area to the Customs．

Customs

    All passengers must pass Customs after Passport Control．There is a choice of two channels：Green and Red．If you have nothing to declare，go through the Green Channel．If you are not sure about your Duty Free allowance(免税限额)or if you have something to declare，go through the Red Channel．Information about Duty Free allowance can be found on special notice-boards in the Baggage Reclaim Area．You should study this information carefully whether you are going through the Red Channel or not．Please note that if you go through the Green Channel，you may be stopped and asked to open your luggage for inspection．

1．All passengers arriving at Heathrow from outside Britain __________．

    A．must go through either Passport Control or Custom

    B．must go through Customs，but not Passport Control

    C．must go through Passport Control and Customs

    D．don’t have to be examined

2．The underlined word“transferring”means _________．

      A．exchanging           B．switching           C．replacing           D．turning

3．If you have only hand luggage，_________．

    A．you may go through the Baggage Reclaim Area to customs

    B．you should go through the Baggage Reclaim Areas

    C．it isn’t necessary for you to go through the Baggage Reclaim Area

    D．it isn’t necessary for you to do anything

4．If you have duty free goods，_______．

      A．you don’t have to go through the Green Channel

      B．you may go through the Green Channel

      C．you must go through the Red Channel

      D．you should go through both Green and Red Channel 

A summary of the physical and chemical nature of life must begin，not on the earth but in the sun；in fact，at the sun’s very center．It is here that is to be found the source of the energy that the sun constantly pours out into space as light and heat．This energy is liberated at the center of the sun as billions upon billions of nuclei hydrogen atoms clash with each other and fuse together to form nuclei of atoms．The output of light and heat of the sun requires that some 600 million tons of hydrogen be converted into helium(氦)in the sun every second．Thus the sun has been doing for several thousands of millions of years．

      The nuclear energy is released at the sun’s center as high-energy gamma radiation, a form of electromagnetic(电磁的)radiation like light and radio waves，only of very much shorter wavelength．This gamma radiation is absorbed by atoms inside the sun，to be remitted at slightly longer wavelengths．This radiation in its turn，is absorbed and remitted．As the energy filters through the layers of Solar inner，it passes through the X-ray part of the spectrum(光)，eventually becoming light．At this stage，it has reached what we call the Solar surface，and can escape into space，without being absorbed further by solar atoms．A very small fraction of the sun’s light and heat is given off in such direction that，after passing unhindered through interplanetary space，it hits the earth．

1．What does the passage mainly discuss?

    A．The production of solar light and heat．

    B．The physical and chemical nature of life．

    C．The conversion of hydrogen to helium．

    D．Radiation in the X—ray part of the spectrum．

2．The passage indicates that，in comparison to radio waves，gamma waves _________．

      A．produce louder sound                                B．are less magnetic

      C．do not form in the sun’s center                           D．are not so long

3．According to the passage，through which of the following does the energy released in the sun pass before it becomes light?

      A．The X-ray part of the spectrum．               B．Electromagnetic space．   

      C．The Solar surface．                                   D．Interplanetary space．
