How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the US.

For some parents, the Internet can seem like a jungle (叢林), filled with danger for their children. But jungles contain wonders as well as dangers and with good guides, some education and a few precautions (預防), the wilds of the Internet can be safely navigated . "Kids have to be on-line. If we tell our kids they can’t be allowed to surf the Internet, we are cutting them from their future,” said an expert.

Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener ". But this can’t be wholly reliable, and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or to do on the Internet. Another way is that Mum or Dad is nearby when the child is surfing the Internet.

A few other tips:

--- Don't put the PC in the child's room but keep it in an area where Mum or Dad can keep an eye on things. That also makes the Internet more of a family activity.

--- Ask your child what he or she has been doing and about any friend they make online,

--- Tell your child not to give on-line strangers personal information, especially like address and phone number.

--- And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

1.What is the best way to protect children from improper materials?

A. To fix a content screener on the computer.

B. To be nearby when they are surfing the Internet.

C. To talk to them and persuade them to tell right from wrong.

D. To buy some search engines for children.

2.Which of the following is TRUE according to the passage?

A. Surfing the Internet is the best way of educating children.

B. Using a content screener is most reliable for keeping children having ways to the Internet.

C. Search engines can help children to select materials fit for them.

D. Children’s not having chances to go to the Internet may have effect on their progress.

3.According to the passage, we can infer that _____.

A. softwares fit for children want programming.

B. the Internet will be protected by law

C. the Internet contains a lot of harmful sites

D. a child who is on-line is in danger

4.What does the passage tell us most?

Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live ---- in the middle of a modern city, or a faraway village --- the chances are that you’ll be disturbed by jet planes, transistor radios, oil-powered engines, etc. we seem to be getting used to noise, too. Some people feel quite lonely without background music while they’re working.

Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums (耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.

One recent report about noise and concentration suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn’t change too much (music, for example) may even help to concentrate.

1.According to this passage, the noise pollution ____________________.

A. has become the worst in the countryside

B. has become better in big cities

C. has spread from cities to villages

D. has been controlled in modern cities

2.Some people have their hearing harmed _____________.

A. while listening to pop music

B. in complete silence

C. when speaking loudly

D. while watching TV

3.Which of the following isn’t included among the things causing noise?

A. trucks B. motorcycles

C. electric engines D. jet planes

4.Scientists have discovered that what prevents people from concentrating on something is _______.

A. all kinds of noise B. great changes in the level of noise

C. background noise D. popular music

By today's standards, my mobile phone is pretty rubbish. It's a Nokia 1616. If that doesn't mean much to you (it's not the kind of phone you see advertised on television), all you need to know is that it's a small, not very heavy device with which you can send and receive telephone calls and text messages. It also has a very handy torch on the top for when you can't find your keys, or when you drop something on the floor in the cinema. Other than that, my phone doesn't do much. Well, it has an alarm, and it probably has a calculator and things like that, but it's nothing compared to a smartphone. Why would I want one of those?

I have often been told that the big advantage of having a smartphone is that "you can do everything with them!" But when was the last time you saw someone doing "everything" with a smartphone? Okay, so they may have an endless list of functions, but generally they are used for checking social networking sites, playing games, and receiving and replying to emails. I'm happy just doing all of those things at home on my laptop.

As far as I can tell, the best thing about having a smartphone is that you can be connected to the Internet all the time. Don't get me wrong, I love the internet, but I just don't see the point of constantly being online. I can't remember the last time I received a Facebook update which was so very urgent that I had to read it as soon as it appeared, and I can't imagine ever having a job which was so important that I would need to read work-related emails immediately. I would think that if someone needed me urgently, they would just ring me rather than send an email. And my trusty Nokia can manage that.

One of the most peculiar(獨特的)effects of the smartphone is, in my opinion, the newly-found addiction to maps and navigation (導航) systems. Is there anything more boring than knowing exactly where you are all of the time?! How do you get to know an area if you don't get lost there a few times? And if you are dependent on online maps, what happens to those great places you find just by chance? You can't exactly find out from Google maps the journey from "here" to" that hidden cafe with the tasty-looking cakes" , or to "that pond next to the church which looks really pretty in the evening sun. " It is, of course, true that we all occasionally need to be pointed in the right direction, but I find that there are often real life humans you can ask.

There are many benefits of having a very basic mobile phone, like the fact that it cost me about twenty pounds, and that I don't have to worry too much about it being stolen .But the main benefit has to be the fact that it provides me with the word 'greatest excuse for my bad habits’. Whether it's turning up late to events ,or getting lost on a trip, or missing buses or trains ,or forgetting about an appointment at work ,I'm pretty sure I'm covered with the following explanation: “I’m really sorry, I don't have a smartphone."

1.The writer uses his Nokia 1616 mainly to _______.

A. play online games

B. do calculating work

C. check social network sites

D. make calls and text messages

2.It can be inferred from the above passage that_______.

A. work-related emails should be answered immediately

B. a laptop and a smartphone share many functions

C. smartphones should always be connected to the net

D. a Facebook update is usually very important

3.According to the passage, if you use navigation systems, you may _____

A. miss some really wonderful places

B. find a boring trip actually exciting

C. be persuaded to eat in a certain café

D. be misled to a totally wrong place

4.The writer’s purpose for writing this article is to______

A. explain why he doesn’t want a smartphone

B. warn readers of the risks of using smartphones

C. complain about the troubles caused by smartphones

D. inform readers of the latest development of mobile phones

根據(jù)下面短文內(nèi)容,從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

The Mississippi

The Mississippi is a great river whose relationship with man goes way back beyond its discovery in the 16th century. The River Indians used it as a highway and as a source of food, and it was they who gave it its name —— “misi” meaning “great” and “sipi” meaning “water”. When the length of its branch, the Missouri, is added to it, the Mississippi becomes greater. 1. . From the source of the Missouri to the tip of the delta (三角洲), it is 2, 480 miles long.

Great rivers are likely to suffer floods. In 1927 the Mississippi flooded 26 thousand acres, sweeping away farms, towns, everything in its path. In 1938 its floods drowned or killed 200 people and made millions homeless. Today the river has largely been controlled. 2. .

Industries have spread down some of the waterways of the delta, but otherwise the delta is a remote place, the homeland of a little colony of French Canadians that the British drove out of Nova Scotia in the 18th century. They still speak French, mixed with English, Indian, Spanish and Negro idioms. They keep to themselves, fanning the rich soil of the delta. 3. __.

4. . Pioneers who first reached its banks wondered not only where it went, but what lay beyond. In 1764 the French founded a city on the right bank of the river, and named it after their king, Louis XV. This city, named St. Louis, became the jumping-off place for the adventurous men and women who opened up the Great Plains, and the way to the Far West.

Some 40 years earlier, at the beginning of the 18th century, the French had founded another city just above the Mississippi delta, New Orleans. 5. . New Orleans is one of the great ports of the world, and one of the greatest terminals for both sea and river traffic.

A. It was the Mississippi that made the city what it is

B. Levees, high banks built of earth, hold back the flood waters

C. Therefore, as we know, it’s the third longest river in the world

D. It is known that the “Great Water” has also been a frontier river

E. However, they paddled up and down the Mississippi in their boats to seek their fortune

F. The “Great Water” always remains a thread (分界線), for the streets of the city are below the level of the river

G. They call themselves Cajuns, who have actually been leading fairly primitive lives and preserving their own traditions
