Many families have recently bought a new TV set, and the idea of changing it just to take advantage of a technology in its infancy(初期)will put many people off the idea. Then there are the additional costs that come along with a 3Dset from needing to get a Blu-ray player that can process the signal to purchasing enough glasses for the entire family to be able to watch a program at the same time.
Another issue is that the glasses are expensive as well as complicated, and have also been known to cause headaches, none of which makes for a pleasant experience.
While manufacturers are working towards glasses-free technology, it just isn’t here yet, and it could be several years before it is commercially successful. That is one of main things that will keep 3D completely in the “fashion” zone for the time being . If the television manufacturers are willing to hold onto the idea until glasses-free choices are available—and they can reach a higher installed(安装)user base—this might very well catch on. Everyone needs to remember, however, that these are businesses, and they are in it to make money. If 3D isn’t selling at the rate they are comfortable with, then they will dump it and move on to the next thing.
Many homes are filled with products that didn’t catch on rapidly and companies ended up leaving them with no support. Do you have an HD DVD player? Remember how the MiniDisc was supposed to replace the CD? For now, it’s easy to see how 3D televisions could join this list of technologies.
There is one upside to the 3D television problem: They have beautiful 2D images. Even if 3D goes away, you still have a great –looking screen and beautiful images. If you are in the market for a new TV and you can afford to drop the couple extra hundred dollars to buy one, you can view it as guaranteeing your purchase in case the technology proves to be effective.

试题分析:
【文章大意】本文是一篇说明文。文章讲述了3D电视的发展前景及其一些弊端。
小题1:C考查推理判断。根据文章第二段中的Then there are the additional costs that come along with a 3Dset from needing to get a Blu-ray player that can process the signal to purchasing enough glasses for the entire family to be able to watch a program at the same time.可知,3D电视还需要许多附带的产品才能满足人们的需要,故选C。
小题2:D考查主旨要义。根据文章第四段中的While manufacturers are working towards glasses-free technology, it just isn’t here yet, and it could be several years before it is commercially successful.可知,这是主题句。这表明目前3D眼睛技术免费还不可能,因为几年之后才能交易成功。故选D。
小题3:C考查细节理解。根据文章第五段中的For now, it’s easy to see how 3D televisions could join this list of technologies.可知,它很快也就被加入淘汰的技术名单中。这说明3D技术不会停留太久。故选C。
小题4:D考查猜测词义。根据文章最后一段中的They have beautiful 2D images. Even if 3D goes away, you still have a great –looking screen and beautiful images.可知,本段讲述3D电视的好处,如果3D不成,还有2D美丽的图像。所以由此推知,其意为:好处。故选D。
小题5:A考查作者的看法。根据文章的整体内容可知,作者第一段发问对3D质疑,接下来说附带产品太多,可能这种技术很快消失。所以作者持批评态度。故选A。

An analysis is issued on a sample of data from a Texas school district. Experts argue convincingly that teacher effectiveness should be measured by students’ gains on standardized tests: Mr. Smith is probably a better teacher than Ms. Brown if his students consistently improve their test scores more than hers do.
Though this approach is appealing, there are tricky issues. For example, what if Ms. Brown teaches in a school where students score so high there is little room for improvement?
The authors try to correct for this problem, as well as other sorts of measurement issues, to generate a measurement of teacher effectiveness. The paper is primarily concerned with how this measure is related to other observable characteristics.
The first finding is that there is a large variation in teacher effectiveness: some teachers consistently have a larger impact on their students’ achievement than others.
Second, easily observable characteristics like having a master’s degree or a passing score on the teacher certification exam are not correlated关联 with teacher effectiveness.
Then what does matter? The most important single influence is experience: first-year teachers are much less effective than others. The second year is significantly better, and by the fourth year, most teachers hit their stride.
It is not entirely clear whether this experience effect is learning by doing (the more you teach, the more effective you become) or survival of the fittest (those who are not good at teaching tend to drop out early.)
From my reading of the paper, both effects appear important and there is no simple answer. The data do suggest, however, that teacher effectiveness is pretty clear by the end of the second year, so the information to make an informed decision is available at that time.
The authors also investigate the contentious 有争议的issue of racial matching of students and teachers. Here they find strong evidence that minority teachers tend to be more effective with minority students. Again, it is unclear whether this is because of a role model effect (students respond better to a teacher of their own race) or an empathy effect 移情效应(teachers empathize better with students of their own race) or something else entirely.
The authors also look at teacher mobility. There is some evidence that teachers who quit teaching or switch schools tend to be below average in effectiveness. This is consistent with the survival-of-the-fittest model.
小题1:The schoolmaster could decide wisely whether to further employ the teacher by the end of the ______.
A.the first year | B.the second year | C.the third year | D.the fourth year |
A.reach their normal level | B.become confident |
C.walk with long steps | D.get bored |
A.teachers will perform better with time passing |
B.ineffective teachers should leave earlier rather than later |
C.teacher’s effectiveness is apparent after a couple of years |
D.a master’s degree will improve teacher’s effectiveness |
A.Students fell secure, so they respond better. |
B.Teachers sympathize with students of their own race. |
C.There are entirely some other identified reasons. |
D.The reasons are far from clear and definite. |
A.The Quality of Teaching |
B.Impact of Teacher Quality on Student Learning |
C.Different Sorts of Measurement Issues |
D.Survival-of-the-fittest Model vs. Learning-by-doing Model |
Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages.
What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve(神经) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation(创造) and the expression for emotions(情感). In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by a smaller number of nerves than the two sides of a woman’s brain are.
小题1:Which of the following is the best title of the article?
A.Research on the Brain |
B.Men and Women are Different in Brain |
C.People’s Different Brains |
D.Who Are Better, Boys or Girls |
A.The different brains make |
B.Sex makes |
C.The different experiences make |
D.The influences(影响) of society make |
A.mathematics | B.physics | C.English | D.chemistry |
A.The left side of brain in boys generally develops better than that in girls. |
B.The left side of brain in girls generally develops better than that in boys. |
C.Men are better than women in all things. |
D.The area in girls used for language skills develops better. |
A.is the same as women’s |
B.is different from women’s |
C.is larger than women’s |
D.is twice as large as women’s |
First, any habit which slows down your silent reading to the speed at which you speak or read aloud, is inefficient. If you point to each word as you read, or move your head, or form the words with your lips, you read poorly. Less obvious habits also hold back reading efficiency (效率). One is "saying" each word silently by moving your tongue or throat; another is "hearing" each word as you read.
These are habits which should have been outgrown long ago. The beginning reader is learning how letters can make words, how written words are pronounced, and how sentences are put together. Your reading purpose is quite different, which is to understand meaning.
It has been supposed that up to 75% of the words in English sentences are not really necessary for expressing the meaning. The secret of silent reading is to find out those key words and phrases which carry the thought, and to pay less attention to words which exist only for grammatical completeness.
An efficient reader can grasp the meaning from a page at least twice as fast as he can read the page aloud. He takes in a whole phrase or thought unit at a time. If he “says" or "hears" words to himself, they are selected ones, said for emphasis.
小题1:This passage is mainly about ______.
A.improving eye movement |
B.reading more widely |
C.changing poor reading habits |
D.reading as fast as you can |
A.improves comprehension |
B.increases reading speed |
C.gives too much emphasis |
D.reduces reading efficiency |
A.to understand all the words |
B.to make fewer eye movements |
C.to understand meaning |
D.to understand the grammatical structures |
A.move their eyes quickly |
B.take in whole phrases or thought units |
C.point at key words |
D.read only important points for speed |
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
小题1:What function isn’t understood by most people on Facebook?
A.Surfing the Internet. |
B.Setting safety protection. |
C.Sharing personal information. |
D.Making foreign friends. |
A.Its process of privacy-setting is too complex. |
B.It displays everything people post. |
C.It lacks privacy controls and security features. |
D.Its post is designed for technical people. |
A.We can avoid our bosses adding us as friends. |
B.We can share applications with friends. |
C.We can separate acquaintances from family. |
D.We can hide different information from different friends. |
