阅读下列短文，从各题所给的A、B、C三个选项中，选出最佳选项。

　　Have you seen Avatar(《阿凡达》)? It's a popular 3D movie, and you may have to wear 3D glasses to see it．The 3D glasses make the images(图像)from the movie look as if they are coming straight at you．

　　More and more 3D movies are coming to theaters．Some say that 3D TV sets will come into our homes in the near future．Three－dimensional technology can make TV and movies more exciting．But people with eye problems may get headaches if they spend too much time watching 3D movies．Why?

　　When we look at an object(物体), each eye sees it at a different angle(角度)．Our eyes send the two images to our brain(大脑), and the brain puts them together．3D technology uses two film projectors(投影机)．One projects a left eye image and the other projects a right eye image．3D glasses allow us to see a different image in each eye．So, when we are watching a 3D movie, our brain can't put together the images sent to our eyes．The brain needs to work harder at “reading” the images．That makes it easier for these people to get dizzy(头晕的)or develop headaches．A famous eye doctor said if your eyes can't focus(聚焦)on the same object at once, you will have trouble watching 3D movies．

　　Robots aren't only in the movies or on TV．One “real” robot recently married a couple at a wedding ceremony in Tokyo, Japan．

　　Fifty guests stood as the music played and the bride(新娘)walked down towards the groom(新郎)．Only one guest stayed seated-the minister(牧师), who happened to be a robot．For this special ceremony, the four-foot tall robot named I-Fairy wore flowers around her head．I-Fairy's eyes flashed colored lights as she pronounced the couple man-and-wife and asked the groom to kiss the bride．The wedding was the first time a marriage had been led by a robot, according to the company that built I-Fairy．

阅读理解，阅读下列短文，从各题所给的A、B、C和D项中选出最佳选项。

　　Lightning(闪电)is shocking, and it happens all over the world! Scientists think that there are more than three million lightning strikes(袭击)every day in the world-that's thirty strikes every second．

　　Lightning can also be very dangerous．Every year, lightning kills people because it can start big fires or because it reaches temperatures up to 28, 000 degrees centigrade．American Roy Sullivan, who worked in a park, holds the record for surviving the most lightning strikes．Between 1942 and 1983, he was hit seven times!

　　So, why does lightning strike? Lightning strikes happen when ice and water in clouds rub(摩擦)together, and cause atmospheric(大气层的)changes．When this happens, it creates a static charge(静电电荷)．Lightning can strike inside the cloud, between two clouds and between a cloud and Earth．It's the last type of strike that is the most dangerous for humans．About 1, 000 people get struck by lightning every year in the United States, and about 100 of them die as a result．

　　Lightning is certainly not something to toy with．When lightning strikes, it's best to stay inside a large building．To stay safe, do not stand under trees, on hills or near water．Trees attract lightning．Also, do not lie down on the ground, otherwise the electricity may go through you and cause a heart disease．

(1)

Lightning strikes ________．
[　　]
A．	happen three billion times each day
B．	will start when there are big fires
C．	can reach very high temperatures
D．	kill all those who work in a park

(2)

What does “surviving” in paragraph 2 mean in Chinese?
[　　]
A．	目睹
B．	幸存
C．	制造
D．	遇难

(3)

We can infer(推断)from paragraph 3 that ________．
[　　]
A．	lightning strikes are caused whenever ice and water meet
B．	lightning between two clouds is the most dangerous for humans
C．	lightning strikes create static charge
D．	about one tenth of the people struck by lightning die every year in America

(4)

Which expression means “to toy with” in the last paragraph?
[　　]
A．	to play with
B．	to take seriously
C．	to show off
D．	to take it easy

(5)

Where's the best place to be when lightning strikes?
[　　]
A．	On top of a hill．
B．	In a swimming pool．
