Last summer, I travelled to Meixian County with my friends. It is a small county at the foot of Taibai Mountain in Shanxi Province. We stayed there for one week and I__1__ my vacation because of the beautiful scenery at the top of the mountain.

I will__2__ forget the day when we climbed the main peak(山顶). The __3__in that area changes very quickly: it was sunny in the early morning when we set out, __4__ it began to rain heavily when we were only halfway up.

Soon，we were all__5__ and some of us wanted to go home. They said, “There is nothing__6__ here. We came to see the scenery，__7__the pouring rain！” However, the guide__8__， “Since we have got wet already, why not just go on with our journey？”

So we carried on up the mountain and，__9__we even noticed, the rain stopped and the sun was smiling again. When we reached the top of the peak, the view was unique (独特的)．

Up there, it was bright and clear. The sky was__10__and the air was fresh. The gentle wind made us feel cool. All the clouds were just like waves in the ocean, __11__ and falling under our feet. We could only see the peaks of mountains, as if they were __12__ floating sparsely (稀疏的) in the ocean. It was a really magical experience.

While we were enjoying the scene, the guide said __13__，“You see, I knew that there would be no rain above the clouds.”

It is __14__. While it may rain below the clouds, the sun is still there above them.

You will never see the sun __15__ you don't try your best to climb to the top of the mountain. If we had stopped and gone home when the rain was very heavy, we would never have seen the beautiful scenery __16__ the clouds. I think this is also true in __17__.

As the song says, “You won't see the rainbow unless you have gone through the thunder and storm.” I think in the__18__， whenever I have any difficulties in my life, I will remember the__19__from the top of Taibai Mountain and the __20__ which touched my heart deeply: There is no rain above the clouds.

The south and east of the Great Lakes is famous for the huge amounts of snow it receives. When the snow starts to fall every year,　people start discussing the phrase “lake-effect snow”.
Lake-effect snow which is influenced by the movement of cold air over the relatively warm water of the Great Lakes often comes in late autumn and early winter. Because of the at least 20 degrees’ difference between the lake water and the overrunning air, it’s easy to form huge amounts of snow.
As the cool air crosses the water of Great Lakes, the lowest levels of the atmosphere begin to warm and pick up moisture. This newly warmed atmosphere is lighter than the cold air above it, so it starts rising. As the changed air continues to climb higher and higher, it finally meets much colder atmosphere which changes the moisture into water drops and ice, forming clouds. After this course repeats a number of times, the clouds become heavier and heavier, and then they are changed into snow and fall down.
The most important point that decides the amount of snowfall is the direction of the wind. If the wind runs perpendicularly（垂直地）across the lake, there won’t be plenty of time for clouds to develop. However, if the wind runs in the opposite direction, clouds will form easily. The longer the cold air travels over the lake, the more moisture it is able to produce, which leads to a greater amount of snow.
The largest amount of the lake-effect snow was found across the U.P. of Michigan, the northwestern Pennsylvania and the far southwestern and northwestern New York, which are all along the south or east of the Great Lakes. It has been over 100 inches of snowfall in a winter season.
【小题1】The level of the snowfall depends on ________.

A．the size of the lake

B．the direction of the wind

C．the temperature of the lake

D．the strength of the wind

【小题2】From the passage, we can learn that ________.

A．clouds are easy to produce with the help of the perpendicular wind

B．cold air always falls down and picks up moisture to form clouds

C．the temperature of the lake water is the same as the overrunning air’s above it

D．the longer journey of the cold atmosphere can make a grater amount of snow

【小题3】The passage is mainly about ________.

A．the influences of the lake-effect snow for local people

B．the weight between moisture and atmosphere

C．how the phrase “lake-effect snow” comes in New York

D．how the lake-effect snow forms around the Great Lakes

People who are hit by lightning and survive often have long-term effects. These may include memory loss, sleep disorders, muscle pain and depression(郁闷).
Experts tell people to seek(寻找) the safety of a building or a hard-top vehicle any time they hear thunder, even if it is not raining. They say lightning can strike as far as sixteen kilometers from any rainfall. Lightning can travel sideways. And at least ten percent of lightning happens without any clouds overhead that you can see.
People who are outdoors should make sure they are not the tallest thing around. Bend(屈身) low to the ground, but do not lie down. And do not stand near a tree or any tall object. Get away from water and anything made of metal. A car is safe, but do not touch any metal inside.
Safety experts say people in buildings should stay away from anything with wires or pipes that lead to the outside. The National Weather Service says if you plan to disconnect any electronic equipment, do so before the storm arrives. Do not use a wired telephone. Do not use water. All these can carry electricity.
Some people think a person struck by lightning carries an electrical charge （电荷） afterward. Experts say this is not true. It is safe to begin emergency treatment.
Each year about four hundred people in the United States are struck by lightning. Last year forty four people died. The average(平均) is close to seventy. The National Weather Service says that is more than the number of people killed by severe storms.
【小题1】According to the passage, which of the following is NOT true?

A．Lightning can happen even if there is no cloud.

B．Lightning won’t do harm to people’s health.

C．Lightning can travel sideways.

D．Lightning can strike very far.

【小题2】The underlined word “disconnect” (in Paragraph 4) refers to “_______”.

A．cut out

B．interrupt

C．disturb

D．cut off

【小题3】Which of the following mustn’t you do in order to seek lightning safety?

A．Hide in a building.	B．Sit in a car.
C．Bend low to the ground.	D．Lie under a tall tree.

【小题4】Which of the following is the main idea of the passage?

A．The latest information about lightning.

B．Some common knowledge about lightning safety.

C．How lightning comes into being.

D．Where we should hide in case of lightning.

The rainbow _____ as the sun came fully out from behind the clouds.
