A. Environment protection
B. Driving experience
C. Self – driving
D. Safety
E. Computing and communications
F. Wireless communications

Today, the Internet is in a few cars; tomorrow, broadband (宽带) will be in all of them. Any capability a personal computer has, a car will have, including two – way wireless communications for receiving e – mail, music, and movies. When you’re crossing the lonely place, the kids can watch TV if they’re bored. Every passenger will have a video feed.

Every car will have a self – driving system linked to GPS satellites. Radar sensors (传感器) will track nearby cars. On the freeway, they’ll slow your car when the car ahead of you slows; in town, they’ll help you park without hitting other cars. At rush hour, you’ll get the routes around traffic jams and accidents. The self – driving system in a car makes it possible for the car to drive itself, though some scientists say that’s 30 to 40 years off.

Motor vehicles today represent 20 to 30 percent of the world’s energy use. In the near future, a small gasoline engine and an electric motor will be brought together. Drivers will use electricity in a storage battery for short distances. Longer term, cars might burn hydrogen or use a fuel cell that converts a fuel like hydrogen and combines it with oxygen to create power. Then the waste will be pure water.

You’ll use the voice control: “Make it a bit cooler” or “find me country music”. Lighter, more reliable electronic controls replace mechanical controls. Fiber optics (光纤) replace electrical wires and light bulbs. Seats will be air – conditioned. The car will travel with one side higher than the other when turning, just as an airplane does now.

Cars will avoid some accidents by maintaining safe following distances, and by sensing sleepy or drunk drivers. Air bags will adapt for every passenger according to their size, weight, and position in case accidents happen.

-- Do you think that would help?
-- And why not buy some English tapes and some books to go with them? I’m sure you’ll find them useful.
-- Yes, that’s a good idea. But I have another difficulty._
-- Oh! Well, for that, you’d better find an English pen friend.

A．Of course.

B．Certainly not.

C．I’m afraid I need your help.

D．Why don’t you buy a radio?

根据短文内容，从下框的A—F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余选项。

A． How can you select your test location（地址）?
B． How many times do you plan to take the test?
C． When do you have to hand in your test scores?
D． What is the most appropriate test date for you?
E． Where do you stand in your high school coursework?
F． What are the factors determining your choice of test time?

The ACT is offered nationally several times a year, between September and June． However, it's not offered at every test center on each test date． If you need to take the ACT on a day other than Saturday because of religious reasons, you’ll want to be especially attentive in selecting a test date because the non-Saturday dates are less frequent and are held at fewer test centers．

One of the first things you should find out, then, is where the ACT is being offered in your area． A quick and easy way to get that information is by accessing ACT's website at www．actstudent．org． Or your high school guidance counselor should be able to give you that information． It's also printed in the booklet Registering for the ACT, which is available free from your school counselor． Often, your own or a neighboring school will serve as a test center．

One important decision you need to make is whether you should take the ACT during your junior or your senior year in high school． A number of factors will affect this decision． First, you should find out when colleges you're interested in need to have your test scores． Is there a special program or scholarship for which you want to apply? If so, is there a deadline by which you need to have test scores submitted to the college or agency? Score reports are normally mailed about 3-7 weeks after the test date． Just be sure you're doing everything, including taking the ACT, early enough to keep all your options open．

Another consideration in deciding when to take the ACT is where you stand in your high school coursework． If you're in a college-prep program and taking a lot of courses in English, mathematics, and science in your sophomore and junior years, it may be wise for you to take the ACT in your junior year, while those subjects are still fresh in your memory． If, on the other hand, you're studying material covered on the ACT during your senior year, it's reasonable to assume that your performance on the ACT might be better then．

Perhaps you'll decide to take the ACT more than once, in hopes of improving your score． In that case, it's probably better to take the exam in your junior year to allow time for a second try． There are several advantages to taking the ACT in your junior year: （i） You probably will have completed much of the coursework corresponding to the material covered on the ACT．（ii）You'll have your ACT scores and other information in time to help make decisions about your final year of high school coursework．（iii） You'll have your ACT scores and information from colleges in time to make decisions about visiting campuses or contacting schools．

____ Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge(隆起) structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. ___ Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer’s ink. They can be recorded easily. ___ Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. ___ When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect(察觉) with the naked eye. ____ Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

A．Special techniques are used to “develop” them.

B．A fingerprint is an impression of the friction ridges of all part of the finger.

C．It is only when the inner skin is injured that the arrangement will be destroyed.

D．With special methods, identification can be achieved successfully within a short time.

E. A latent(潜在的) print is the chance reproduction of the friction ridges deposited on the surface of an item.
F. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
G. Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable.
