Chinese Spring Festival marks the first day of a new year, so the first meal is rather important. People from the North and the South have different 26 about the foods they eat on this 27 day. In Northern China, people 28 eat Jiaozi. The word Jiaozi in Chinese means the 29 and the beginning of time. According to historical 30 , in the past people from the North and the South both ate Jiaozi on Chinese New Year’s Day. Perhaps 31 the areas in Southern China 32 more rice than those in Northern China, southern people slowly 33 to eat many other kinds of food on New Year’s Day. 34 , the most common foods for the first 35 are noodles, New Year Cake and Tangyuan. The noodle 36 long life. The New Year Cake is called Niangao in Chinese, which 37 the hope of improvement in 38 year after year. Tangyuan is a symbol of 39 according to the Chinese.
To 40 a New Year visit to relatives and friends is an important activity during the Spring Festival. People also send cards to 41 a New Year’s greeting. What children love most is to set off firecrackers. 42 , as the pace of life is becoming faster and faster, people have 43 new ways to celebrate the Chinese traditional New Year. For example, many people no longer send out greeting cards. 44 , they use short messages or emails. Also to travel during the New Year holidays has come into 45.

Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的) sight loss for the first time. Researchers say because mice’s genes are so similar to humans’, their findings could lead to the treatment of more genetic diseases.
Scientists at the University of California, Davis studied information from a data bank of mice’s genetic material. They found 347 genes linked to eye problems, with just 86 of them having been studied in the past.
Only around 50 to 75 percent of hereditary eye diseases in human can be explained with present science. The researchers believe these hundreds of new genes found in mice could be a key to explaining-and therefore being able to treat the other 25-50 percent.
“This is extremely valuable for people with hereditary eye disease,” said researcher Professor Ala Moshiri. “All researchers are going to start using these data. In the past, we knew the problem was there but we didn’t know where to look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these genetic diseases will be treatable.” Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the baby’s parents!
Thanks to data from the International Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mice’s genes to those of patients.
1.How many hereditary-sight-loss-related genes were newly found?
A.86. B.261.
C.300. D.347.
2.Why is the percentage of genetic eye problems mentioned in paragraph 3?
A.To show the significance of studying mice’s genes.
B.To prove mice’s genes are similar to humans’.
C.To warn the high risk level of suffering them.
D.To explain how common they are among people.
3.What should scientists do first to unlock secrets of genetic blindness?
A.Compare humans’ genes with mice’s.
B.Recognize each gene’s role of humans.
C.Set apart a gene of a mouse each time.
D.Figure out each gene’s function of a mouse.
4.What can be a suitable title for the text?
A.New Ways to Cure Sight Loss

For many people, the name Baskin-Robbins is linked to sweet memories of eating ice cream．Irvine Robbins, who helped create this famous company, died in May at the age of ninety．His life's work of making fun and exciting ice cream flavors changed the way Americans enjoy this food．
Irvine Robbins opened his first ice cream store in 1945 in California．At the time, there were no stores that sold only ice cream．His sister's husband, Burton Baskin, also opened his own ice cream stores．
In 1948 they combined their six stores into one business．Baskin and Robbins realized that they were too busy to operate each store well．So, they decided to sell part of each operation to the manager of that store．This permitted the company to grow quickly．
By 1953, they renamed their company Baskin-Robbins．They advertised that they sold 31 kinds of ice cream to show the many choices buyers had．There was one flavor for every day of the month．
Robbins and Baskin sold "Lunar Cheesecake" the day after astronauts landed on the moon in 1969．Other flavors included "ChaChaCha", for cherry chocolate chip, and Robbins' personal favorite "Jamoca Almond Fudge"．They said: "We sell fun, not just ice cream．"
By 1967, there were 500 Baskin-Robbins stores in the United States．The business partners sold their company that year．Today, there are more than 5,800 Baskin-Robbins stores around the world．
1.What is the main idea of the passage?
A．The managers of Baskin-Robbins． B．The start of Baskin-Robbins．
C．The production of Baskin Robbins． D．The great success of Baskin-Robbins．
2.From the text we learn that _____．
A．Baskin-Robbins was the only shop selling ice cream in 1945
B．Baskin-Robbins was famous for their special ice cream flavors
C．Baskin-Robbins grew quickly because they combined their other stores together
D．there had been more than 5,800 Baskin-Robbins stores around the world by 1967
3.What was probably the main reason for Baskin-Robbins' success?
A．They sold not only ice cream, but fun．
B．They renamed their company．
C．They put all their hearts into the business．
D．They sold "Lunar Cheesecake"．
4.It can be inferred from Paragraph 5 that
A．Jamoca Almond Fudge is Baskins' favorite
B．Cherry chocolate chip sells best
C．Robbins and Baskin were good at inventing new ice creams
D．Lunar cheesecake was invented for the astronauts

Is there link between humans and climate change or not?This question was first studied in the early 1900s.Since then,many scientists have thought that our actions do make a difference.In 1997,the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions from 2008 to 2012.Some countries have decided to continue these reductions until 2020.More recently,the Paris Agreement,struck by nearly 200 countries,also aims to limit global warming.But just now how much warmer it will get depends on how deeply countries cut carbon emissions.
This is how much temperatures would rise by 2100 even if nations live up to the initial Paris promises to reduce carbon emissions;this rise could still put coastal cities under water and drive over half of all species to extinction.
To meet this minimum goal,the Agreement requires countries to tighten emissions targets every five years.Even this increase could sink some islands,worsen drought and drive a decline of up to a third in the number of species.
This is the most ambitious goal for temperature rise set by the Paris Agreement,after a push by low-lying island nations like Kiribati,which say limiting temperature rise to 1.5℃ could save them from sinking.
This is how much temperatures have risen since the industrial age began,putting us 40% of the way to the 2℃ point.
The baseline here is average global temperature before the start of the industrial age.
1.It can be concluded from paragraph 1 that .
A. gas emissions have been effectively reduced in developed countries
B. humans have made continuous efforts to slow down global warming
C. the problem of global warming will have been quite solved by 2020
D. the Paris Agreement is more influential than the Kyoto Protocol
2.If nations could only keep the initial promises of the Paris Agreement,what would happen by the year 2100?
A. The human population would increase by one third.
B. Little over 50 % of all species would still exist.
C. Nations would not need to tighten their emissions targets.
D. The Agreement’s minimum goal would not be reached.
3.If those island nations not far above sea level are to survive,the maximum temperature rise,since the start of the industrial age,should be .

2℃
To meet this minimum goal, the Agreement requires countries to tighten emissions targets every five years. Even this increase could sink some islands, worse drought(干旱) and drive a decline of up to a third in the number of species.
1.5℃
This is the most ambitious goal for temperature rise set by the Paris Agreement, after a push by low-lying island nations like Kiribati, which say limiting temperature rise to 1.5℃ could save them from sinking.
