14．Rice plants normally grow well in till water．But most will die if they are completely underwater for more than four days．Now，researchers have identified a gene（基因）that helps rice survive longer underwater．They say the discovery will lead to new kinds of rice plants that can survive flooding，and therefore reach their final aim，ensuring more dependable food supplies．
Tests are now being done in Laos，Bangladesh and India．The researchers say experimental rice plants with the gene have survived underwater as long as two weeks．When flooding happens，most kinds of rice plants cannot get enough oxygen，carbon dioxide or sunlight．But the scientists say crop loss depends on several conditions．These include soil condiions and plant age．Others include the amount of time the plant is underwater and the amount of fertilizer（肥料）used on the crop．
On a genetic（遗传的）map of rice，the scientists became interested in a group of three genes．They experimented with one of them，a gene known as Sub-One-A．They found that when this gene becomes very active，it improves the ability of rice to survive longer when rice is covered by water．They believe it succeeds because it affects the reaction to hormones（荷尔蒙）．They control the ability of a flooded plant to survive．Placing the gene into rice plants that are especially good for conditions in India，researchers say the genetically engineered plants not only survived but also produced good crops．
The researchers are now trying to identify all the genes governed by the Sub-One-A gene．Being able to leave water on rice plants for an additional week might also help farmers prevent the growth of weeds．Less weed growth around their crops would mean less need for herbicide（除草剂）chemicals．

5．Crop loss depends on all the following conditions EXCEPTB．
A．soil conditions and plant age
B．the amount of water the plant stands in
C．the amount of fertilizer used on the crop
D．the amount of time the plant is underwater
6．What is the final aim of this research？D
A．To identify the gene that helps rice survive underwater．
B．To increase the ability of rice to fight against floods．
C．To help farmers spend less time removing weeds．
D．To make sure of enough food supplies．
7．What does the underlined word"They"in Paragrph 3 refer to？D
A．Genes．B．The experiments．C．Genetically engineered plants．D．Hormones．
8．What would be the best title for the passage？C
A．Rice research is going on in Laos and India
B．How to reduce the influence of floods on rice
C．Gene researchers work on flood-resistant rice
D．A great discovery in the agricultural field．

11．"The chair is out to kill us，"says James Levine，a professor at the Mayo School of Medicine．Most of us have years of sitting experiences，considering ourselves quite good at it．（36）BBut unfortunately，a good deal of data suggests that we're off our chairs to spend so much time on the vast variety of other seats where we're fond of parking our bottoms．Here are some things that scientists have learned about the insidious（潜伏的）nature of sitting．
Sitting position has gone wrong．
The human body is designed for walking．（37）EBut lately，not so much．In general，scientists believe，Americans now sit for more than half of their walking hours．Sadly，the sitting position exerts force on the body which can lead to a lot of trouble including poor circulation（血液循环），aches and pains．
（38）A
We're not using much energy when we're sitting still．（39）G It is also just another way of saying"watch out for extra pounds．"It is mainly the chair that has caused the increase in obesity rates．A person with a desk job may burn 300 calories a day at work，but the same person might burn 2，300calories a day in jobs that require considerable physical efforts．In other words，we need more walking to burn more calories．
Realize the damage．
Sitting at your desk and working hard for hours on end can increase your chances of getting a promotion．（40）DWhen comparing people who spent the most time sitting with those who spent the least time sitting，researchers found more sitting increases the risks of death from all causes．

A．Make people become too fat．
B．We will say nature intends us to do it．
C．They ought to work out to build their bodies．
D．But it also brings people diseases or even early death．
E．Certainly people have done that for thousands of years．
F．We should be more patient and work longer than before．
G．That is just another way of saying"we are not burning many calories"．

6．The parts of a traditional piano have changed very little for（61）hundreds（hundred） of years．The keys are black and white（62）incolor．But now an electronic，piano-like musical instrument replaces those keys with surfaces（63）that/whichrespond to touch．
A start-up company called ROLI began selling the electronic keyboard in 2013．The keyboard is known as Seaboard．It does not have（64）thesame white and black keys as a piano．Instead it is（65）made（make） from soft and rubbery materials．
Roland Lamb is the（66）inventor（invent） of Seaboard and a jazz piano player．He says he invented Seaboard so he could create（67）different（difference） kinds of sounds with the instrument．
"I wanted to be able（68）to expressexpress） more from the keyboard and create the kinds of sounds that people could create on a guitar or a saxophone．And I sat at the piano thinking（69）whyI can't strike a note and then move it．"
The way a person touches the keys on a Seaboard（70）affects（affect） the instrument's sound．This new technology enables the player to create sounds that traditional pianos cannot make．

16．Sorry tointerrupt/have interrupted （打断） you，but I need to ask you to come downstairs．

3．The date of the trial has been advanced by one week．

20．The hard work wasworthwhile （值得的） because I passed the exam．

1．Tourism probably started in Roman times．Rich Romans visited friends and family who were working in another part of the Roman empire．But when the empire broke down，this kind of tourism stopped．
In the early 17th century，the idea of the"Grand Tour"was born．Rich young English people sailed across the English Channel（英吉利海峡）．They visited the most beautiful and important European cities of the time，including Paris in France，and Rome and Venice（威尼斯）in Italy．Their tours lasted for two to four years，and the tourists stayed a few weeks or months in each city．The"Grand Tour"was an important part of young people's education-but only for the rich．
In the 18th century，tourism began to change．For example，people in the UK started to visit some towns，such as Bath to"take the waters"．They believed that the water there was good for their health．So large and expensive hotels were built in these towns．
In the 19th century，travel became much more popular and faster．When the first railways were built in the 1820s，it was easier for people to travel between towns，so they started to go for holidays by the sea．And some started to have holidays in the countryside as cities became larger，noisier and dirtier．
Traveling by sea also became faster and safer when the first steamships were built．People began to travel more to far-away countries．
The 20th century saw cars become more and more popular among ordinary people．Planes were made larger，so ticket prices dropped and more people used them．
Thus tourism grew．In 1949，Russian journalist Vladimir Raitz started a company called Horizon Holidays．The company organizes everything-plane tickets，hotel rooms，even food-and tourists pay for it all before they leave home．The package tour and modern tourist industry was born．
The first travel agency in China was set up as early as 1949．But tourism did not take off until 1978．In 2002，the industry was worth 500 billion Yuan and became an important part of China's social development．

21．In the early times，the travelersC．
A．only came from Roman
B．traveled by boat
C．were very wealthy
D．were very young and strong
22．Which of the following is true？C
A．The young men learned little from Grand Tour．
B．More people chose planes for its cheap price．
C．In 2002，tourism became a fundamental part of China's social development．
D．Tourism became faster and safer when the first railways were built in the 18th century．
23．Cplayed the most important role in the tourism development．
A．Education B．Money C．Transportation D．People's ideas
24．Modern tourism was bornA．
A．in 1949
B．in 1978
C．in the early 17th century
D．in Roman times
25．The underlined phrase"take off"（in the last paragraph） meansB．

B．develop very fast
C．remove hats and clothes
D．bring down the prices．
