What is Math Anxiety?

Math anxiety or fear of math is actually quite common. Math anxiety is quite    1   to stage-fright. Why does someone suffer stage-fright? Fear of something going wrong in front of a crowd? Fear of   2   the lines? Fear of being judged   3   ? Fear of going completely blank? Math anxiety shows fear of some type. The fear that one won't be able to do the math or the fear that it's too hard or the fear of failure which often results from having a lack of   4   . For the most part, math anxiety is the   5   about doing the math right, our minds draw a   6   and we think we'll fail and of course the more frustrated and anxious our minds become, the   7__   the chance for drawing blanks.

Where Does Math Anxiety Come From?

Usually math anxiety results from    8  experiences in mathematics. Math anxiety is often due to poor teaching and poor experiences in math which typically leads to math   __9___. When one tries to memorize procedures, rules and routines without much   10   , the math is quickly forgotten and   11   soon sets in. Think about your experiences with one concept --- the division of fractions(分数). You probably learned about reciprocals（倒数） and inverses(倒转). Well, you memorized the rule and it   12   . Why does it work? Think of math as memorizing all the procedures -- what if you forget a few? Therefore, with this type of strategy, a good   13   will help, but, what if you don’t have a good memory? Understanding the math is critical. Once students   14   they can do the math, the whole notion of math anxiety can be overcome. Teachers and parents play an important   15   in ensuring students understand the math being presented to them.

CANBERRA(Reuters)—Australia’s kangaroos are genetically similar to humans and may have first evolved in China, Australian researchers said Tuesday.
Scientists said they had for the first time mapped the genetic code of the Australian marsupials(有袋类)and found much of it was similar to the genome for humans, the government backed Center of Excellence for Kangaroo Genomics said.
“There are a few differences, we have a few more of this, a few less of that, but they are the same genes and a lot of them are in the same order,”center Director Jenny Graves told reporters in Melbourne.
“We thought they’d be completely scrambled, but they’re not. There is great chunks of the human genome which is sitting right there in the kangaroo genome,” Graves said, according to AAP.
Humans and knagaroos last shared an ancestor at least 150 million years ago, the researchers found, while mice and humans separated and went in different ways from one another only 70 million years ago.
Kangaroos first evolved in China, but migrated across the America to Australia and Antarctica, they said.
“Kangaroos are hugely informative about what we were like 150 million years ago,” Graves said.
68.Where does the kangaroo first develop according the scientists?
A.In China.    B.In America. C.In Australia.       D.In Antarctica.
69.What does the passage mainly tell us?
A.How the Kangaroo first evolved.      B.Kangaroo’ genetic code have been mapped.
C.Kangaroos’genes are close to humans’.     D.Scientists did much research into Kangaroos.
70.What does the underlined word “scrambled” probably mean in the fourth paragraph?
A.Funny. B.Wrong.       C.Curious.      D.Right.

When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies. These seem to be the most important basic needs of the people we are trying to help. However, it's far from enough. Ladies and gentlemen, we've got to come up with some better ideas to help them.

I was very surprised, then, when I read about a plan to make cheap laptop computers for children in developing countries. A man called Nicholas Negroponte invented a cheap laptop computer, which can run without electricity. He decided to invent this computer after he visited a school in Cambodia.

The laptop which Mr. Negroponte has designed is a little different from the normal laptop computers you can buy in the shops. One difference is that it is covered in rubber so that it is very strong and won't be damaged easily. As an electricity supply can be a problem in developing countries, the computer also has a special handle so that children can wind the computer up to give it extra power when needed.

These special laptop computers will cost less than 100 US dollars and Mr. Negroponte wants to build as many as 15 million machines in the first year of production. The idea is that these computers will help the children's education as they will be able to access the Internet. These computers might not help the people in developing countries immediately, but by improving children's education they should help people to find their own solutions to their problems in the long term.

Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK, and, probably in many other countries too, millions of mobile phones are thrown away every year. The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them. In this way we will be able to achieve two important goals at the same time. We will reduce the waste we produce and help others. In other words, we will be able to 'kill two birds with one stone', and that is always a good thing.

It's an excellent idea to recycle old mobile phones because _______.

A. it reduces waste and can help others  

B. it prevents waste and can earn lots of money

C. it can send the waste produced by developed countries to other countries

D. it is good for the environment and very educative for phone users

The author gives the example of Mr. Negroponte's cheap computers _______.

A. to show what high tech can bring us.

B. to illustrate the kindness of people in the developed countries

C. to show how to find business opportunities in developing countries

D. to give an example of how to help developing countries

Which of the following statements is TRUE about Mr. Negroponte's cheap computers?

      A. His computers don’t need any power to function well.

      B. His computers are covered with rubber so that they are very cheap.

      C. His computers will help children in developing countries to have better education.

      D. His computers will help people in developing countries to find all the solutions.

Where does this passage probably come from?

      A. A magazine      B. A newspaper        C. A lecture          D. An advertisement

A frugal (节俭) traveler, I’m on the road for three to six months out of a year, and all that wandering takes not just energy but organization as well. Before I set off, I will research destinations (目的地), book flights and hotels, and figure out what to do when I arrive. To do all those things,I have a long list of websites and other resources (资源). Since many people are now planning their summer vacations, I think I’d share my experience.

Once I have decided on a destination, I head straight for a little website called “Google” to do research. One of the first searches is for my destination with the words “frugal” and “affordable”. Seriously! When I went to Hawaii in 2008, the search immediately brought out the Pomaikai “Lucky” Farm B&B, a farm with comfortable rooms for $ 80 a night — a steal in America’s most expensive vacation spots.

I don’t just surf the Web, however — print still has its uses. I have a guidebook with me. When I travel for work, the information it provides is quite useful.

In order to know about the culture of my destination, I often turn to novels. In Manhattan, there’s Idlewild Books, where all kinds of books and novels sit side by side. But you could just easily visit the local independent bookstores or public libraries. If there’s really nothing in your area, log on the LongitudeBooks.com.

When it’s time to book a flight, I’m back online. My first stop is kayak.com, which searches almost every other booking site. I’ve also started to use ITAsoftware.com’s QPX system. It was developed for the airline companies.

Finally, when I’m ready to buy the ticket, I’ll go to the airline’s own website, because it offers the lowest price for the ticket. Then I’ll check SeatGuru.com, which offers seat maps of most airlines’ planes to find the best, most comfortable spot.

What does the writer usually do to prepare for a trip?

   A. He turns to some organizations.

   B. He wanders around to get information.

   C. He consults websites and other resources.

   D. He asks people who are planning summer vacations.

The underlined word “steal” most probably means “______”.

   A. bargain                   B. farm                 C. room                D. price

To know the culture of your destination, which of the following is suggested by the writer?

   A. Tour the place and experience it.

   B. Watch TV programs about the place.

   C. Visit bookstores or public libraries.

   D. Read the guidebooks about the place.

Where does the writer buy his flight tickets?

   A. On the airline’s own website.

   B. On kayak.com.

   C. On ITAsoftware.com.

   D. On SeatGuru.com.
