1 . China became the first country to clone a monkey using non-reproductive cells, reducing the need to keep lab monkeys and paving the way for more accurate, effective, and affordable animal tests for new drugs .

By December of 2017, Chinese scientists had created two clone macaques named "Zhong Zhong" and "Hua Hua" by nuclear transferring of somatic cells -- any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.

"Cloning a monkey using somatic cells has been a world-class challenge because it is a primate（灵长类）that shares its genetic makeup, therefore all of its complexity, with humans." Pu Muming said.

"For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes, " Pu said.

"By cloning monkeys using somatic cells, we can mass produce large numbers of genetically identical（相同的）offspring in a short time, and even change their genes to suit our needs," he added. "This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine."

"This achievement will help China lead the world research in an international science project related to neural（神经的）mapping of primate brains，," he said. However, bio labs from the United States, Japan, and European countries are also very able, and they will quickly catch up to China after the monkey cloning technology is made public, Sun added."This means we have to innovate（创新）continuously and work extra harder this year to stay ahead," he said.

3 . 阅读下面短文，根据所给情节进行续写使之构成一个完整的故事。

Lauriesat quietly in the empty dressing room at theice-skatingrink (溜冰场).She had not been skating in any competition since her leftkneewas badly injured in an accident six months ago. As she waited for her turn to skate，Laurie was very nervous. She knew that today was a very important day in hercome back.

“If I canwintoday.” she thought, “I can skate in the World Cup next year and then maybe I can make it to the Olympics.”

Laurie was told that she had a toughcompetitionthis year, and a girl from Connecticut named Jinny Jordan who was really strong in everything.“She is the one you have to beat this year." the coach said.

Minutes later, the door opened and Laurie saw a young woman who was about her own age. The young woman dumped some of her belongings onto a chair. The bag fell to the floor with a thud (砰地一声).

Laurie felt uncomfortable as she looked at Jinny. “So this is my competition，” thought Laurie.” Because of her, I may lose tonight. ”

“This costume (服装）was my mom's idea,”Jinnystarted the conversation, looking down at her red. white, and blue skating dress. “It look like a flag. ”

Laurie couldn't keep from smiling. She pointed to Jinny’s skating bag. Some stuff fell out of your bag" Laurie said.

Jinny looked at the clothing and equipment that lay scattered on the floor. As she began to gather her belongings, the door opened.

“Jinny.” called someone, “You’d better give the tape of your music to the sound engineer right away."

“I thought I gave him mymusic tapean hour ago," said Jinny. Tell him it's the green box with my initials (姓名的首字母）written in white in the right-hand corner.”

“He said you never gave it to him. and he's getting angry.”

“Then I don't know what I did withit,- said Jinny, hurrying out.

Laurie knew that music was nearly asimrportantto the program as skating itself. If she lost her music tape, she might as well forget about skating. Laurie stood up and walked to the chair to do a few more knee bends.

5 . In a recent series of experiments at the University of California, researchers studied toddlers’ thinking about winners and losers, bullies (欺凌) and victims.

In the first experiment, toddlers (学步儿童) watched a scene in which two puppets (木偶) had conflicting goals: One was crossing a stage from right to left, and the other from left to right. The puppets met in the middle and stopped. Eventually one puppet bowed down and moved aside, letting the other one pass by. Then researchers asked the toddlers which puppet they liked. The result: 20 out of 23 toddlers picked the higher-status puppet — the one that did not bow or move aside. It seems that individuals can gain status for being dominant (占优势的) and toddlers like winners better than losers.

But then researchers had another question: Do toddlers like winners no matter how they win? So, researchers did another experiment very similar to the one described above. But this time, the conflict ended because one puppet knocked the other down and out of the way. Now when the toddlers were asked who they liked, the results were different: Only 4 out of 23 children liked the winner.

These data suggest that children already love a winner by the age of 21-31 months. This does not necessarily mean that the preference is inborn: 21 months is enough time to learn a lot of things. But if a preference for winners is something we learn, we appear to learn it quite early.

Even more interesting, the preference for winners is not absolute. Children in our study did not like a winner who knocked a competitor down. This suggests that already by the age of 21-31 months, children’s liking for winners is balanced with other social concerns, including perhaps a general preference for nice or helpful people over aggressive ones.

In a time when the news is full of stories of public figures who celebrate winning at all costs, these results give us much confidence. Humans understand dominance, but we also expect strong individuals to guide, protect and help others. This feels like good news.

1. One of the purposes of the experiments is to ________.

A．teach toddlers how to gain higher status

B．offer toddlers a chance to watch a scene

C．observe the process of toddlers’ solving a conflict

D．find out toddlers’ attitude toward winners and losers

2. The toddlers regarded bowing and moving aside as a sign of ________.

A．obeying rules

B．gaining status

C．giving in to the other

D．showing good manners

3. What does the second experiment tell us about toddlers?

A．They are excellent learners.

B．They are always changeable.

C．They show mercy to the loser.

D．They value kindness over winning.

4. What does the author think of the results of the series of experiments?

A．Disappointing.	B．Encouraging.
C．Unexpected.	D．Controversial.

In early 1800’s a new kind power changed transportation and trade along the Mississippi River. This power was steam. People already knew that how to use steam engines to run machines. Some people wanted to move boats by the same way. The first steamboats to travel on the Mississippi was the “New Orleans”, which made its first trip in 1811. It was a great successful, and by 1819 there were 191 steamboats travel on the long river. In the past, the farmers products went to other parts of the country used steamboats. The manufacturers whose trade depend on cheap and easy transportation used steamboats so well.
