A

In 1826, a French man named Niepce needed pictures for his business. But he was not a good artist. He invented a very simple camera. He put it in a window of his

house and took a picture of his garden. That was the first photo.

The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype.

Soon, other people began to use Daguerre's way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains.

In about 1840, photography was developed. Then photographers could take pictures of people and moving things. That was not simple. The photographers had to carry a lot of films and other machines. But this did not stop them, for example, some in the United States worked so hard.

Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike.

Photography also became one kind of art by the end of the 19th century. Some photos were not just copies of the real world. They showed our feelings, like other kinds of art.

A.business

There is growing concern about food insecurity in the developing world. Rising food prices, weather emergencies and political problems are deepening the struggle for families in many countries.

Three UN agencies have published a report recently, saying high prices are likely to continue. Gregory Barrow, who is with the World Food Program in Rome, says, “If you look at the places where the World Food Program works, particularly in developing countries, you see people who might be spending more than 60 percent of their salary in purchasing food for their families.”

East Africa is suffering its worst drought in years. In Kenya, at least three and a half million people are going hungry, mostly in the north. Yet food is going to waste in central Kenya. Now, farmers there want the government to buy their food and give it to those in need. Farmers say bad roads and lack of transportation make it difficult for them to get their produce to the market.

Mr. Barrow says, “It needs the government to make some arrangements such as

providing transport. They can buy it at a good price, then give it to those people instead of asking for food from overseas, which is very bad. When we are throwing away food, they are asking for food from overseas.”

Economists say that imports reduce local food prices, decrease productivity(生产效率) and increase the dependency on other countries. Farmers in Kenya hope the government can pay higher prices for their crops so that they can feed more Kenyans.

28.What is the best title for this passage?

A.Kenya Imports Food from Abroad

B.World Food Program in Rome.

C.The Poor Suffer from High Food Prices.

D. A Report Published by Three UN Agencies.

29.What do we know about Kenya from the passage?

A.The people in central Kenya are suffering from hunger.

B.At least three and a half million Kenyans lack food.

C.The Kenyan government wants to improve road conditions.

D.People in northern Kenya refuse to ask for food from overseas.

30.What does “they” in the fourth paragraph refer to?

A.The people of northern Kenya.

https://www.doczj.com/doc/fa4360061.html,ernment officials.

C.The farmers of central Kenya.

D.Kenyan economists.

31.Which of the following statements is TRUE, according to this passage?

A.Gregory Barrow suggests that Kenya make good use of overseas food.

B.People in northern Kenya are suffering the drought less than the central.

C.Economists believe importing food from abroad may cause problems.

D. Kenyan government hopes to buy the native crops at higher prices.

we can't tell a contestant is winning because he is really talented or because there

is no comparison?

The administrative department really contributed a lot in the popularity of the Voice of China. In the past, there were no other draft shows(选秀节目) ranked as high as Super Girl and Super Boy. Even though there were some draft shows which seemed to share the popularity, it never turned out true. All the other draft shows were shadowed by the ones on Hunan TV. One example was that since draft shows of Hunan TV were broadcast on Friday night, the draft shows of other stations were shifted to Saturday or Sunday. However, Hunan TV didn't get their permission for broadcasting shows in 2012.

And if this were not bad enough, SARFT did a great favor for it. SARFT issued a regulation, saying that all draft shows should be broadcast after 10:30 pm at night. Zhejiang TV declared long before the regulation th at since was “no audition(海选),no PK, no rise in rank, no voting, no champion”, its program was never a draft show. So, in 2012, all the opponents of Zhejiang TV had to broadcast their draft shows after 10:30 pm while the Voice of China was permitted to be broadcast in prime time.

If you really think about it, there's no essential difference between a draft show Hunan S a reason f Voice of popular pr The re excellent

and the Voice of China. It also selected people from all over the country, how did they say this was different from a draft show? No PK, really? PK doesn't mean one versus one! A team versus a team is called PK too. And “no rise in rank” is just a switch of concepts because at the end of every game, some left the stage and some stayed. If there was really “no champion”, how come there was only one “g ood voice of China” at the final round? All these were rising in rank, in disguise(隐性).

Under such circumstances, the Voice of China even got praise. We are not saying that it is not a good show; we are saying that there's regret about the show since it had no opponent.

32.The following factors are important in making the Voice of China popular EXCEPT

_______.

A.the unique quality of the voice of China

B.the policy support from SARFT and the administrative department

C.the favorable broadcasting time

D.the shortage of good opponents

33.The passage mainly tells us _______.

A.the voice of China is not a real draft show

B.the draft shows of Hunan Satellite TV still cause our attention

C.the advantages of the Voice of China

D.the reasons why Hunan Satellite TV is losing its leading position

34.What's the author's attitude towards the voice of China?

A. supportive

B. doubtful

C. optimistic

D. hopeful

35.Which is TRUE according to the passage?

A.SARFT issued a regulation, saying that all draft shows should be broadcast after

10:30 pm at night.

B.Draft shows of Hunan TV were broadcast on Sunday night.

C.In the past, there were some draft shows ranked as high as Super Girl.

D.The Voice of China is a program of Hunan Satellite TV.

Parents have started to notice many benefits associated with online math and reading tutoring services. Both conventional and online tutoring offers children academic help. 36 . Here's why.

Online tutoring, much like conventional tutoring, helps a student complete difficult assignments, and is geared toward(使适合) improving grades. This method, however, allows your children to master their studies from the convenience of home, making it more convenient for both children and parents who have a busy schedule. Since the Internet is probably already one of your children's favorite activities, working education programs into their online time is easier than convincing them to apply traditional face to face methods. 37 .These abilities are essential in today's world.

Online tutoring also enables very individualized programs and plans. Often, people

believe online tutoring is designed for the masses. 38 . Beyond that, they often accommodate your children's learning speed. Not all children learn at the same rate, and feeling rushed means that important lessons are not mastered. Online tutoring eliminates that worry because children advance when they're ready, not when a tutor suggests its time.

39 . Students who are not self-motivated may use study time for surfing the Internet. Others need the more hands-on learning approach offered by one-on-one sessions.

So, how do you truly identify whether online tutoring is right for you and your child? 40 . If this method is not effective, contact a local tutor or tutoring center.

A.The online method is increasing in popularity, however.

B.The only way is to give it a try.

C.Online tutoring may not be for everyone, however.

D.Learning these requirements early will help to ensure future success.

E.However, most online tutoring programs are personally designed to match each child.

F.The conveniences of a home-based program are more important than your child's

education.

G.Participating in online programs also enhances students' online research

techniques and typing skills.

Hi Worried:

I’m sorry to know that you’re having such a bad time at the moment. The truth is everyone will have one of those periods when things seem to be wrong, so you don’t have to worry so much. The important thing is to learn to control your temper so that you may not do or say anything you’ll regret. Here are three useful tips:

First, talk to someone you trust about how you feel. This is a good way of letting your anger out without hurting others or yourself. Second, go outdoors and play team games with your friends,as physical exercise is an effective way to get rid of anger .And third, remain optimistic about your future. Such a positive attitude

towards life can be helpful in lifting your spirits.

I hope you’ll soon feel calmer and carry on as normal.

Yours, Mike
