With so many difficult problems ______, the newly-elected president, Obama, is to have a hard time。

With so many friends       me, I had no difficulty finishing the work on time.

I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?” He looked perturbed (不安).“Do you want to try it first?" he said. It didn't quite sound like a question. "Do I need to?" I replied. "There's nothing wrong with it?" This made him look a bit insulted and I started to feel bad. "No, no. But you should try it," he said encouragingly." Compare it with the others. "

     I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.

     But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out my chosen camera from the cupboard, show how it took excellent pictures of my fellow shoppers... and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.

      Why do we think that new options (选择) still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.

     A. try the camera to see if there was anything wrong with it

     B. compare the camera he had chosen with the others

     C. get more information about different companies

     D. trust him and stop asking questions

2. What does the writer mean by "it would be worth half what I paid for it"  (Paragraph 2) ?

     A. He should get a 50% discount.

     B. The price of the camera was unreasonably high.

     C. The quality of the camera was not good.

     D. The camera would soon fall in value.

3. The writer decided to try the model he had chosen because he __ .

     A. knew very little about it

     B. didn't trust the shop assistant

     C. wanted to make sure the one he chose would be the best

     D. had a special interest in taking pictures of his fellow shoppers

4. It can be inferred from the passage that in the writer's opinion, __

     A. people waste too much money on cameras

     B. cameras have become an important part of our daily life

     C. we don't actually need so many choices when buying a product

     D. famous companies care more about profit than quality

The Book of Life

So far,scientists have named about 1.8 million living species(物种)，and that’s just a small number of what probably exists on Earth.With so many plants,animals,and other living things covering the planet,it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by.

A soon-to-be-started Web site might help.An international team of researchers has announced the creation of Web-based Encyclopedia(百科全书) of Life(EoL).The project aims to list every species on Earth in a single,easy-to-use reference guide.

To get the encyclopedia started,the creators will use information from scientific databases(数据库) that already exist.And eventually,in special sections of the site,non-scientists with specialized knowledge will come to help.Bird-watchers,for example,will be able to input what birds they’ve seen and where.To make sure the encyclopedia is accurate,scientists will review much of the information added to it.

As the EoL develops,you might find it useful for school projects.The site will feature(以……为特色)_____special pages for kids who are studying ecosystems in their neighborhoods.Another convenient feature of the EoL is that you’ll be able to pick the level of detail you want to see to match your interests,age,and knowledge.

It now takes years for scientists to collect all the data they need to describe and analyze species.The creators of the Encyclopedia of Life hope that their new fool will speed up that process.

The Web based EoL aims to _______.

A.find out what covers the earth

B.list all living things on Earth

C.work out the number of birds

D.save the existing plants

One characteristic of the EoL is that _______.

A.it is run by school students

B.it focuses on different types of grass

C.it provides different levels of information

D.it allows non-scientists to review its data

In the last paragraph,“that process”means _______.

A.analyzing species                                                 B.creating a new tool

C.collecting data                                              D.describing species
