Keeping fish as pets is a popular hobby. Fish take up very little room, are inexpensive to feed, and provide an interesting and colorful display in any room. A tank, or an aquarium, must be chosen carefully. Many new aquarium owners buy too many fish for their tanks. Fish can’t be crowded. Two fish can live comfortably in each gallon of water, only ten fish can live in a five-gallon tank. Can you see why a goldfish would not live long in a tiny, round bowl? If too many fish are kept together, they will not have enough oxygen or room to swim about freely. They will have more diseases. Also, some kinds of fish can’t be kept together. As your interest in fish grows, the number of fish you have may grow, too. Then you may want to invest in another tank. If you start with a ten-gallon aquarium, what kind of fish would be best? The two major groups of tropical fish are those that lay eggs and those that give birth to live young. If you want to raise young fish, guppies would be the best choice because they can produce many babies in a short time. You can buy fish and aquariums in most pet stores. Ask the owners to help you choose the right fish. You can also find many books about tropical fish in the library.

64. If nine fish live in three gallons of water, the fish may _________.

A. breathe easily     B. swim about freely C. get ill D. not get enough to eat

65. The underlined phrases “invest in” in Para 3 is closest in meaning to _______.

A. buy   B. borrow  C. make D. sell

66. In the passage the author provides us with some useful tips on how to keep fish well EXCEPT ________.

A. selecting a suitable tank size  B. feeding enough oxygen into the tank  C. choosing the right group of fish  D. reading some books about fish

67. From the passage we can know _______.

A. very few people are interested in keeping fish

B. the size of your tank decides how many fish you can keep

C. guppies are a kind of fish that are good at laying eggs

D. you can raise different kinds of fish together

閱讀理解

閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項,并在答題卡上將該項涂黑。

  It seems that some people go out of their way to get into trouble.That's more or less what happened the night that Nashville Police Officer Floyd Hyde was on duty.

  “I was on the way to a personal-inj ury accident in West Nashville.As I got onto Highway 40,blue lights and sirens(警笛)going,I fell in behind a gold Pontiac Firebird that suddenly seemed to take off quickly down the highway.The driver somehow flustered at the sight of me.He was going more than a hundred miles an hour and began passing cars on the shoulder.”

  But Hyde couldn't go after him.Taking care of injured people is always more important than worrying about speeders,so the officer had to stay on his way to the accident.But he did try to keep the Fi rebird in sight as he drove,hoping another nearby unit would be able to step in and stop the speeding car.As it.turned out,keeping the Firebird in sight was not that difficult.Every turn the Pontiac made was the very turn the officer needed to get to the accident scene.

  Hyde followed the Pontiac all the way to his destination。At that point he found another unit had already arrived at the accident scene.His help wasn't needed.Now he was free to try to stop the driver of the Firebird,who by this time had developed something new to panic about.

  “Just about that time,”Hyde says,“I saw fire coming out from under that car,with blue smoke and oil going everywhere.He'd blown his engine.Now he had to stop.”

  “After I arrested him,I asked him why he was running。He told me he didn't have a driver's license.”

  That accident cost the driver of the Firehird plenty-a thousand dollars for the new engine-not to mention the charges for driving without a license,attempting to run away, and dangerous driving.

(1)

The meaning of“flustered”in Paragraph 2 is related to ________

[  ]

A.

shame

B.

hate

C.

anger

D.

fear

(2)

[  ]

A.

Because he was racing with another driver on the road.

B.

Because he realized he had to hurry to the accident scene.

C.

Because he thought the police officer wanted to stop him.

D.

Because he wanted to overtake other cars on the shoulder.

(3)

Which of the following statements is true?

[  ]

A.

Someone else was taking care of the injured person.

B.

The Pontiac reached its destination at the accident scene.

C.

Hyde knew where he was going by following the right car.

Lawmakers in the United States have expanded an investigation into the use of location-tracking systems on mobile devices. The action follows recent reports about the storing of information on the Apple iPhone. Some people consider location tracking to be a threat to personal privacy and security.
Allan Friedman, the research director, says, “All wireless companies do some location tracking as part of their networks. This information is usually stored by the companies, not the devices, and there are laws to protect it. Law enforcement(執(zhí)法) agencies, for example, have to have a fairly high standard before it can access that data. And the phone company is also prohibited from selling that information.
Now, two researchers report that location tracking information is being stored directly on Apple devices. They said Apple’s newest operating systems gather global positioning system and timestamp information. The information is stored on the device in a file that is also uploaded (上傳) to any computer that the device is connected to. The researchers say the information is available to anyone who has access to the device or computer.
Allan Friedman says, “This raises additional concerns. There’s the idea that because it’s on my phone and on my computer, rogue applications(惡意程序) that I pay for or that I’m tricked into downloading may be able to access this data and somehow misuse it.”
Apple says it is “not tracking the location of your iPhone”. It is simply keeping a database of Wi-Fi hotspots and cellphone towers near the user’s location. This information is meant to help the iPhone quickly find its location when needed.
Letters have been sent to some of the leading mobile device developers, including Apple and Google. The letters asked for more information about their location tracking systems. Allan Friedman calls this an important start to strengthening privacy laws. He says, “There aren’t strong controls over things like location information, what they are doing with it, how long they are keeping it. And perhaps the most important question is, is my location data with other facts about me?”
【小題1】Why did American lawmakers investigate the use of location-tracking systems on cell-phones?

A.Because the systems can store users’ information
B.Because many users have suffered loss after using them.
C.Because it is thought to threaten users’ privacy.
D.Because many reporters have shown the problem of the systems.
【小題2】 Allan Friedman believes that ________.
A.wireless companies focus on personal privacy.
B.people are forbidden to get access to private data at will
C.phone companies may sell private information secretly
D.customers may ask wireless companies to locate their tracking
【小題3】 What do we know from Paragraph 3?
A. Location tracking information is stored online.
B.Apple’s newest operating systems collect all kinds of information.
C.Location tracking information may be uploaded to any iPhone.
D.Apple’s newest operating systems may reveal the private information of users.
【小題4】Which of the following statements is TRUE according to the passage?
A.Apple denies that it tracks the location of users.
B.The researchers may misunderstand the Apple’s systems.
C.The global positioning system is to blame for rogue applications.
D.The iPhone can quickly find its location by using its user’s information.
