Traveling can be a very fun and exciting way to vacation with your family, but it does not always turn out as expected. I have traveled a lot with my family over the years, but some experiences are worth forgetting altogether. I remember a particular traveling experience which sticks out in my mind for the wrong reasons.

My dad and stepmom had decided to drive to California for our family vacation. This was supposed to provide educational value, since we would be able to stop along the way and look at various sites in each state. Everything was going as planned until we decided to take a break and stop at the Grand Canyon(大峡谷). I had always wanted to see this exciting place and had decided to write a report on it for my eight-grade English class. We got out of the car and were walking on one of the paths to get to a cliff(悬崖) so we could take a family photo when I slipped(滑倒) and fell down. I fell on a piece of rock, and felt great pain run up my leg at once. My dad took me to the nearest hospital and, after an eight-hour wait in the emergency room（急诊室）, found out that I broke two bones in my foot.

Needless to say, our vacation was no fun for me because I was in pain during the whole two-week trip. I ended up making an appointment the day we got home to see a doctor for a check-up. That was definitely not what I consider fun or a great vacation, and it really put a dent in our sightseeing plans.

Now satellites are helping to forecast（预报）the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere（大气）, because this is where the weather forms（形成）. They send these pictures to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.

 Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare（比较）them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.

 So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.

Satellites travel _____________.

A. in space               B. in the atmosphere

C. above the ground       D. above space

Why do we use the weather satellites to take pictures of the atmosphere? Because __________.

A. the weather satellites can do it easily

B. clouds form there

C. the weather forms there

D. the pictures can forecast the weather

Meteorologists forecast the weather __________.

A. when they have received satellite pictures

B. after they have compared new satellite pictures with earlier ones

C. before they received satellite pictures

D. during they study satellite pictures

The main（主要的）idea of this passage is that satellites are now used in _________.

A. taking pictures of the atmosphere

B. receiving pictures of the atmosphere

C. doing other work in many ways

D. weather forecasting

New software is able to analyze exactly how many hairs there are in a patch of skin and could help in testing the effectiveness of baldness(秃头) treatments and depilatory(脱毛的) creams, say Australian researchers.

Researchers from CSIRO Mathematical and Information Sciences in Sydney report their findings in the November issue of the journal Skin Research and Technology.

The software, developed with a UK company, will make it easier for researchers developing hair removal creams to accurately assess how well they work, says Dr Pascal Vallotton.

"Up to now they were counting the number of hairs that survived after treatment by hand. That's hard work and it's difficult because you may count a hair twice or you may miss it." he said.

The software relies on images captured by a small flatbed scanner(扫描仪) pressed onto the skin. Using a mathematical algorithm(算法), the software then identifies and traces each individual hair based on an understanding of a hair's unique features, such as its relative straightness.

The software is able to distinguish between hairs and other features on the skin such as wounds or moles(痣).

"Our skin irregularities(不规则) make it difficult to say this is a hair or this is a mole," Dr Vallotton said.

Comparison between earlier and later images can also determine if hair is growing quickly or slowly, he says.

Unfortunately, to check the accuracy of the software, the researchers still had to adopt the old-fashioned method of counting hairs, helped by volunteers from neighboring labs who put their skins on the line for science.

"We had 12 volunteers, mostly from neighboring labs, and we acquired images of hair before and after treatment," Dr Vallotton said.

To ensure an accurate count, the individual hairs had to be marked off as they were counted, but after such a laborious process, the researchers were pleased to discover the software results were comparable to the manual(手工的) count.

Dr Vallotton says the software could also be useful in testing the effectiveness of balding(秃头的) treatments and counting or tracing substances other than hairs, that are long and thin and otherwise difficult to image.

64. What do we know about the new software?

A. It has replaced human labor completely.           B. It is mainly used to detect hair problems.

C. It can be used for develop new medicine.          D. It can be used to test medical treatments.

65. What plays a key role in counting the number of hairs with the software?

A. A scanner.                                           B. A calculator. 

C. A hair's unique feature.                          D. A mathematical algorithm.

66. What did the 12 volunteers do in the experiment?

A. They counted the hairs by hand.                 B. They divided the hairs into parts.

C. They controlled laborious process.              D. They offered their hair for experiment.

67. Which is the best title of the text?

A. Do you think it is possible to count hairs?       

B. New software makes counting hairs easy.

C. Australians find new treatments for baldness.  

D. New software is found in Britain and Australia.
