  We cannot feel speed. But our senses let us know that we are moving. We see things moving past us and feel that we are being shaken.

  We can feel acceleration, an increase in speed but we notice it for only a short time. For example, we feel it during the takeoff (起飞) run of a plane.

  We feel the plane's acceleration because our bodies do not gain speed as fast as the plane does. It seems that something is pushing us back against the seat. Actually, our bodies are trying to stay in the same place, while the plane is carrying us forward.

  Soon the plane reaches a steady (不变的) speed. Then because there is no longer any change in speed, the feeling of forward motion stops.

1.We can tell that we are moving by ________ .

[  ]

A.feeling ourselves being shaken

B.feeling the speed

C.watching things move past

D.both A and C

2.Acceleration is the name for ________ .

[  ]

A.a steady speed
B.an increase in speed
C.any kind of movement
D.the movement of a plane

3.During the takeoff of a plane, we feel that we are being ________ .

[  ]

A.lift out of the seat
B.pushed back against the seat
C.pushed down into the seat
D.thrown forward

4.We feel the plane's acceleration because our bodies gain speed ________ .

[  ]

A.before the plane
B.faster than the plane
C.as fast as the plane
D.more slowly than the plane

5.This feeling stops when ________ .

[  ]

A.the plane stops climbing

B.the plane lands

C.there is no longer any change in speed

D.we begin to feel speed

Face adversity(逆境)with a smile

  I told my friend Graham that I often cycle the two miles from my house to the town centre but unfortunately there is a big hill on the route.He   1   , "You mean fortunately." He explained that I should be glad of the   2   exercise that the hill provided.

  My   3   to the hill has now changed.I used to   4   as I approached it but now I tell myself the following.This hill will exercise my heart and lungs.It will help me to   5   and get fit.It will mean that I live longer.This hill is my friend.  6   , I have a smile of   7   as I reach the top of the hill.

  Problems are there to be faced and   8  .We cannot achieve anything with a/an   9   life.Helen Keller was the first deaf and blind person to   10   an University degree.She wrote, "Character cannot be   11   in ease and quiet.Only through   12   of trial and suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved."

  One of the main   13   of success in life is our attitude towards adversity.At times we all face hardships, problems, accidents and difficulties.  14   we cannot choose the adversity, we can choose our attitude towards it.

  Douglas Bader was 21 when in 1931 he had both legs amputated(截肢)following a flying accident.He was   15   to fly again and went on to become one of the leading flying aces.He was a/an   16   to others during the war.He said, "Don't listen to anyone who tells you that you can't do this or that.That's nonsense.  17   your mind you'll never   18   crutches(拐杖)or a stick, then have a go at everything.Go to school, join in all the games you can.Go   19   you want to.But never, never let them   20   you that things are too difficult or impossible."

  In some countries in which there is very little rain at any time, the farmers have to irrigate their fields.Irrigation is easy enough if there is a great river near the crops, and if there is plenty of water in it.Canals carry the river water to the fields when necessary.In some seasons there may be too much water in the river, and the water may flood all the land near it.At other times the river water may not be enough for all the farmers, and then it will be difficult to irrigate the fields.

  To prevent these difficulties, a dam may be built across the river.This will store water for dry seasons, and in wet seasons it will prevent the flooding of the land.A great lake will, no doubt, be formed behind the dam, and this may mean that houses and fields will be covered with water.Most people will accept that and will be ready to move to other places.Then the country can have the right amount of water at all times; more crops will be grown, there will be more food for everyone, and there will be no more floods.

  We cannot use sea water for irrigation; the salt will not allow the crops to grow.Fresh water is always needed, and it is very difficult and costly to make fresh water from sea water.This is done in a few countries, but the fresh water is for drinking.There is not enough at present for irrigation.Perhaps a scientist will one day invent a cheaper way of producing fresh water from the sea.If fresh water could be made cheaply, we could grow more food.

(1)

(2)

In order to keep the country having the right amount of water at all times, ________ should be built.

[  ]

A.

canals

B.

dams

C.

factories

D.

plants

(3)

The main idea of the passage is that ________.

[  ]

A.

irrigation is the best way to produce more food for humans

B.

many ways have been tried to save water

C.

irrigation is necessary for farmers to have a good harvest

D.

scientists should try their best to make sea water fresh to meet the needs of society

(4)

Which of the following is NOT wrong?

[  ]

A.

Sea water can be used to irrigate the fields.

B.

Scientists have found ways to take fresh water out of sea water.

C.

It seems that water plays little role in producing crops.

  Green attackers are taking over America.No.Not attackers from space, just plants.You might not think of plants as dangerous, but in this case they are threatening nature's delicate(脆弱的)food web.

  The attackers are plants from other countries brought here to make gardens and yards look pretty.Ever since people started to arrive on America's shores, they've carried along trees, flowers, and vegetables from other places.

  Now there are so many of those plants, and they are crowding out the native plants that have lived here since before human settlers arrived.And that's a problem, says Dr Doug Tallamy.He's an insect expert at the University of Delaware.He explains that almost all the plant-eating insects in the United States-90% of them-are specialized.That means they eat only certain plants.

  Pretty orange and black monarch butterflies, for example, can only dine on one plant:milkweed.If people cut down milkweed and replace it with something else, the butterflies starve, because their bodies cannot accept any other food.

  But trouble doesn't stop there; it goes right across the food web.When insects can't get the right plants to eat and they die off, then the birds don't have enough bugs(小虫)for their meals.Tallamy points out that almost all migrating birds depend on insects to feed their young.

  “We cannot let the plants and animals around us disappear,”says Tallamy.“The way to preserve them is to give them food to eat.But when we plant non-native plants, we are hitting the food web, because then we don't have the insects the birds need to live.”

  Fewer of the right plants mean fewer bugs, and fewer bugs mean fewer birds.And that's bad for the Earth, because we need a variety of living things to keep the planet healthy and beautiful.

(1)

In the author's opinion, what kind of plant is dangerous?

[  ]

A.

Poisonous plants.

B.

Native plants.

C.

Non-native plants.

D.

Gene-modified plants.

(2)

How did those non-native plants arrive in America?

[  ]

A.

They were brought in by big companies.

B.

They were carried by visitors and immigrants.

C.

They were spread by big winds across oceans.

D.

They were planted by foreign gardeners.

(3)

What are the specialized plants for the 90% of American plant-eating insects?

[  ]

A.

The plants that make gardens and yards look pretty.

B.

The native plants existing before humans came to America.

C.

The plants that need living environment like milkweed.

D.

The plants carried by the first settlers.

(4)

By writing the passage, the author wanted to ________.

[  ]

A.

explain how food web is made up

B.

suggest protecting native plants

C.

suggest protecting our environment

D.

teach us some knowledge about biology
