The Dangers at the Beach British beaches look harmless，but there are hidden dangers．
Allergy
The lesser weever is the fish to look out for on British beaches．It lies almost buried in the sand with just its mouth and fin exposed，a trap for unlucky fishermen and beachgoers walking around in the shallows．If you stand on a weever fish，it'll sting （刺） you badly．The sting may cause heart attacks，and shock，though usually it just causes pain，redness and swelling．
Many people have an allergic reaction to the fish and may start to sweat，develop a faster heartbeat and feel sick as the poison gets further into the body．People who have been stung should take painkillers and if they develop an allergic reaction to the sting，an antihistamine （a drug used to treat an allergy） is recommended．
Sea currents
But fish are the least of your worries on the beach．The force of the sea is much more dangerous than anything swimming about inside it．
Coastguards are warning the public not to swim if there is a red flag flying on a beach and to find out about local tides and currents．
Dangerous swimming
The Coastguard Agency says people should not swim if they feel unwell，for at least an hour after a meal，if they have been drinking alcohol or if they are cold and tired．They also warn against swimming alone，swimming too far out to sea if you have breathing problems．
Pollution
A recent study of UK beaches showed more than 10% are failing to meet standards for clean water．The Marine Conservation Society said polluted water was still being pumped into the sea in some areas and was winding its way onto beaches．But the water companies say the society's standards are too tough and that 90% of British beaches pass European standards．
（1）What can we learn about the lesser weever from the passage？ BB
A．Its poison can be washed off by water．
B．Its sting is usually serious．
C．It buries itself deep in the sand．
D．It can be dangerous on the beach．
（2）From the passage，we know you'd better swim CC．
A．when there is a red flag flying on the beach

C．together with friends
D．just after eating
（3）Which of the following can best describe the UK beaches？ AA

1．Seeing a volcano erupt is a wonderful experience，and you can really feel the heat by climbing to the summit（山頂） of Pacaya for a close-up view.There are guided tours every day up this highly active volcano from Antigua，giving travelers a chance to see Mother Nature at her most powerful.
Pacaya is an easy drive from Antigua，a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week Festival.No matter when you come to Antigua，you won't miss the Pacaya-tour companies.
But climbing Pacaya is no easy job，it is 2，560 metres high，and reaching the summit takes two to three hours of seemingly one step forward and two-step back movements.As you climb，you hear the dull sounds of eruptions high above.Steaming，hot remains from recent eruptions begin to line the path as you near the active summit：the McKenney Cone（火山錐）.Just as though you are going to walk over to the edge of the cone，the road turns to the left and up to the relative safety of the old，inactive summit.
Many tours are timed so that you arrive at the cone of the volcano in plenty of time for sunset and the full contrast between the erupting red lava and the darkening sky.On a good day the view from the summit is extremely exciting.The active mouth boils，sending red lava over its sides，and once in a while shoots hot streams up to 100 metres into the air.There is a strong bad smell in the air even if you take care to be upwind of the cone.As evening turns deeper into the night，the burning lava quietly falls down the side of the volcano.For you，too ，it is time to get down.
（1）What is the main purpose of the passage？
A．To attract tourists to Pacaya.
B．To describe the beauty of Pacaya.
C．To introduce guided tours to Pacaya.
D．To explain the power of nature at Pacaya.
（2）Antigua is an island.
A．where people can enjoy cultural festival
B．where the daring Pacaya tour starts
C．that gives a close up view of Pacaya
D．that is famous for its tour companies
（3）Climbing to the McKenney Cone，people will.
A．walk directly to the active summit
B．hear the continuous loud noise from above
C．make greater efforts than to other summits
D．see a path lined with remains of earlier eruptions
（4）Many tours are timed for people to.
A．get down the mountain in time when night falls
B．avoid the smell from the upwind direction of the cone
C．enjoy the fantastic eruption against the darkening sky
D．appreciate the scenery of the 2，560-metre-high mountain發(fā)布：2025/1/1 13:30:1組卷：8難度：0.5 -

3．The sky is a large place，and though it has been carefully examined for centuries，new features still turn up.Last March it was the rule of Uranus（天王星），and last week astronomers announced what may turn out to be a new planet，though a very small one，in the solar system.
The object was first sighted last month by Charles Kowal，an astronomer at the Hale Observatories in Pasadena，Calif.Mr Kowal observed a faint trail of light on photographic plates，indicating that something was moving in relation to the background of stars.Other observers have confirmed the discovery.
The "mini-planet"，identified for the time being as "Object-Kowal"，appears to be about 1.5 billion miles away，between the orbit of Saturn and Uranus，and its diameter（直徑）has been estimated at between 100 and 400 miles.Its orbit has not been determined yet，but if the orbit proves to be roughly circular，like that of the major planets，the new object would probably take 66 to 70 years to make a circuit of the sun.
Some astronomers have speculated that Mr Kowal's discovery may be the first indication of an asteroid（小行星）belt beyond Saturn.
（1）What may have been found in the solar system according to the first paragraph？
A．A small new planet.
B．A new solar system.
C．A large new object.
D．A large new planet.
（2）What can we learn from the second paragraph？
A．What the object is like.
B．How the object was found.
C．Where the astronomers live.
D．Why the object was moving.
（3）What magazine might this passage be taken from？
A．Astronomy.
B．Industry.
C．Spaceflight.
D．Agriculture.發(fā)布：2024/12/4 17:30:2組卷：22難度：0.7
