[2015河南鄭州三月模擬] The year of 2014 saw smart people al?ways busy inventing useful things,which have helped to make the world better,smar?ter and a little more fun. Now,let's take a look at some of the inventions. Super Banana Australian biogeneticist (生物遺傳學(xué)家) James Dale visited Uganda,a poor African country,in the early 2000s,where he found that 15〜30 per cent of children under 5 were at risk of going blind because they did not get enough vitamin A. Dale also learned that people there love bananas. They eat 3  to 11 bananas a day. So he came up with the idea to plant bananas containing added nutri?tion in order to improve Ugandans' health. With the help of Bill Gates' foundation,Dale developed the "super ba?nana". He added a gene to the fruit,making it rich in vi?tamin A.

  Coaching Basketball Basketball is popular worldwide,partly because you only need a hoop (籃蟹) and a ball to play the game. But this simple game has experienced a technology makeover this year with the development of a smartsensor basket?ball.

The ball,called the 94Fifty Basketball,has nine sen?sors inside. They can tell you anything from how fast you are going to how accurate your shot angles are.

With a Bluetooth chip inside,the basketball can con?nect to your smartphone and tell you in the voice of a coach to "snap your wrist"? or "go faster", depending on the data.

  The Hovercraft (懸浮滑板) Thanks to the Californiabased company Hendo,fly?ing past your friends on a floating board could soon be?come a reality.

The hovercraft has four small engines. These create a special magnetic field which produces enough force to lift the board off the ground.

  At the moment,the hoverboard can only float an inch off the ground for 15 minutes and must fly over a metal material. It's expensive too,at $ 10,000 (61,810yuan) , but the company hopes that one day the technology could be used.

  Wireless Electricity Most of us could not bear to live without wireless In?ternet. We use it every day for everything from our phones to our cars. But one company wants to go a step further,by combining wireless technology with electrici?ty.

  That's right,no more tangled (纏繞的) wires and no more having to sit and hold your cellphone near a power socket (插座) in the corner of the room. WiTricity,a US company,has invented technology that can power objects up to 2. 4 metres away. It uses a special plugin coil (線圈) that creates a magnetic field！

15. Which of the following statements would James Dale agree with?

   A. Children in Uganda should eat fewer bananas.

   B. Vitamin A is largely found in fruits like bananas.

   C. Super bananas are definitely a safe biological prod?uct.

   D. People's eating habits can be used to develop new food.

16. What is the biggest advantage of the 94Fifty Basket?ball?

   A. The sensors hidden inside can help players run faster in a game.

   B. It can help players to improve their shooting and ball handling skills.

   C. It allows players to connect to their smartphones while playing basketball.

   D. The Bluetooth chip inside allows its users to listen to music while playing basketball.

17. What can we learn about the hovercraft from the text?

   A. It enables its users to float off the ground freely.

   B. It can work on many different kinds of surfaces.

   C. It still needs to improve its power and efficiency.

   D. It is an affordable means of transport for a family.

18. What do the hovercraft and wireless electricity have in common according to the text?

   A. They create magnetic fields to produce power.

   B. They apply technologies to many things in life.

   C. They apply technologies which can produce elec?tricity.

   D. They use wireless technology to improve their products.

Good morning,everyone！

The topic of my speech is "My Chinese Dream”. Which is known to all,the education of rural areas are falling behind other areas. And the children there are longing for knowledges. Therefore,the problem about the lack of teachers is especially seriously. It puzzles me whether parents and friends aren't for my idea of being a rural teacher. I understand theirs thoughts and feelings,and I think the children in rural areas are in great need of me. I'll study hard to go college,thus realize my dream. I won't regret my choice. I'll struggle for with my dream. Come on and join me!

Thank you！

  When asked about happiness,we usually think of something ex?traordinary,an absolute delight,which seems to get rarer the older we get.

  For kids,happiness has a magical quality. Their delight at win?ning a race or getting a new bike is unreserved (毫無掩飾的) .

  In the teenage years the concept of happiness changes. Suddenly it's conditional on such things as excitement,love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.

In adulthood the things that bring deep joy―love,marriage,birth―also bring responsibility and the risk of loss. For adults,happiness is complicated (復(fù)雜的) .

  My definition of happiness is "the capacity for enjoyment". The more we can enjoy what we have,the happier we are. It's easy to overlook the pleasure we get from the company of friends,the freedom to live where we please,and even good health.

  I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunchbox and had the house to myself. Then I spent an unin?terrupted morning writing,which I love. When the kids and my husband came home,1 enjoyed their noise after the quiet of the day.

  Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother,who raised 14 children,had much of either. She did have a network of close friends and family,and maybe this is what satisfied her.

  We,however,with so many choices and such pressure to succeed in every area* have turned happiness into one more thing we've got to have. We're so selfcon?scious about our "right" to it that it's making us miserable. So we chase it and equal it with wealth and success,without noticing that the people who have those things aren't necessarily happier.

  Happiness isn't about what happens to us―it's about how we see what hap?pens to us. It's the skilful way of finding a positive for every negative. It's not wish?ing for what we don't have,but enjoying what we do possess.

1. As people grow older,they         .

   A. feel it harder to experience happiness

   B. associate their happiness less with others

   C. will take fewer risks in pursuing happiness

   D. tend to believe responsibility means happiness

2. What can we learn about the author from Paragraphs 5 and 6?

   A. She cares little about her own health.

   B. She enjoys the freedom of travelling.

   C. She is easily pleased by little things in daily life.

   D. She prefers getting pleasure from housework.

3. What can be inferred from Paragraph 7?

   A. Psychologists think satisfying work is key to happiness.

   B. Psychologists' opinion is well proved by Grandma's case.

   C. Grandma often found time for social gatherings.

   D. Grandma's happiness came from modest expectations of life.

4. People who equal happiness with wealth and success         .

   A. consider pressure something blocking their way

   B. stress their right to happiness too much

   C. are at a loss to make correct choices

   D. are more likely to be happy
