In a study published in the U. S. journal Science, researchers from the Chinese Academy of Agricultural Sciences(CAAS) and the University of Florida identified the chemical combinations and genetic recipe for better tomato flavor(味道).
“In recent years, consumers often complain that the modern tomato is less flavorful than it once was” said co-principal researcher Sanwen Huang. “Our results provide a practical road map for breeding tomato varieties with better flavor.”
For the study, a 170-person consumer group was created to evaluate 160 tomatoes representing 101 varieties, based on qualities such as “overall liking” and “flavor degree”. The results pointed to dozens of chemical compounds of interest, and further research using a statistical model discovered 33 flavor compounds connected with consumer liking, such as glucose(葡萄糖). The reason why modern tomatoes don’t taste good anymore is that a total of 13 of these flavor-associated compounds “were significantly reduced in modern varieties,” their paper wrote. Moreover, the researchers found that smaller fruit tended to have greater sugar content, suggesting that “selection for more sizable tomatoes has cost sweetness and flavor”.
Based on this knowledge, Huang and Professor Harry Klee of the University of Florida studied the whole genomes of 398 varieties of tomato, identifying about 250 positions of genes on a chromosome(染色体), which controlled tomato flavor.
“We’re just fixing what has been damaged over the last half century to push them back to where they were a century ago,” said Klee in a statement. “We can make the supermarket tomato taste noticeably better.” Klee said new tomato varieties with better flavor could be ready in three to four years. In addition, “the genes and pathways identified here in the tomato almost certainly point to pathways worth researching for improvement of flavor quality in other fruit crops,” they wrote.
1.According to the text, the study ________.
A. was carried out just through a survey
B. was conducted by Chinese researchers themselves
C. was completely focused on the genes of different tomatoes
D. was done with the background of declining flavor of tomatoes
2.The researchers have found that ________ in the study.
A. bigger tomatoes are much sweeter
B. some genetic positions affect the taste of tomatoes
C. some chemical compounds make tomatoes less tasty
D. a total of 13 flavor-associated compounds make tomatoes appealing in taste
3.What is the influence of the study according to the text?
A. The study lays the foundation for further researches to improve other fruit crops’ flavor.
B. The study makes it possible for us to have noticeably more tasty tomatoes next year.
C. The study provides a road for where to plant tomatoes with better flavor.
D. The study has fixed all the genes of existing tomatoes.

Scientists in Britain have managed to teach bumblebees(大黄蜂) to pull strings to get to food and then pass on what they have learned to others in their colony(群体)—showing a high level of intelligence despite their tiny brains.
Researchers at Queen Mary University of London said the experiments, often used to test the intelligence of apes (猿) and birds, showed for the first time that some insects are up to the task, and can also pass skills on through several generations.
The findings add to the evidence suggesting the ability for “culture spread” — the ability to learn and pass on knowledge and skills — may not be exclusive to humans.
In the research, published in the journal PLOS Biology on Tuesday, the scientists were able to train 23 out of a group of 40 bees to pull strings with their legs and feet.
The strings were attached to discs — or artificial “flowers” — containing food at their center but placed under a transparent screen. The bees, spotting the food beneath the screen, learned to pull the “flowers” out by pulling the string with their legs and feet to be able to get to it.
From another group of bees given the chance to solve the task without any training, only two of 110 were successful.
Another group of bees was then allowed to observe the trained bees pulling the strings, and 60 percent of them successfully learned the skill. Finally, trained bees were put in colonies, and the scientists found the technique spread successfully to a majority of the colony’s worker bees.
Lars Chittka, a Queen Mary University professor who guided the project, said the team is interested in figuring out the brain processes behind the bees’ learning and teaching skills.
1.What does the underlined word “exclusive” in Paragraph 3 probably mean?
A. Ordinary. B. Unique. C. Beneficial. D. Widespread.
2.What did the researchers find about bees?
A. Bees learn best in insects.
B. Bees are as clever as birds.
C. Bees are born good learners.
D. Bees can be trained to learn skills.
3.What may the research team focus on next?
A. What else bees can do. B. Where bees learn skills.
C. How bees teach others. D. How bees’ brain work.
4.What may be the best title for the text?
A. Small bees, great abilities B. Bees can learn and teach
C. Bees are smarter D. Let bees learn

Homework
Do maths problems 15 through 25. State the different forms of the verbs on page 50 of your French workbook. Read pages 12 through 20 of the Shakespeare play, and don’t forget to fill in the missing chemical symbols on the worksheet.
Sound like a list of your homework for the next few nights — or maybe even just for tonight? 1.It’s your teachers’ way of evaluating how much you understand what’s going on in class. And it helps strengthen important concepts. Here are some tips on how to do your homework.
2.It’s inviting to start with the easy things to get them out of the way. However, you’ll have the most energy and focus when you begin, so it’s best to use this mental power on the subjects that are most challenging. Later, when you’re more tired, you can focus on the simpler things. If you get stuck on a problem, try to figure it out as well as you can — but don’t spend too much time on it because this can mess up your homework schedule for the rest of the night. 3.But don’t pick someone whom you’ll be up all night chatting with, or you’ll never get it done!
Most people’s attention spans aren’t very long, so take some breaks while doing your homework. Sitting for too long without relaxing will make you less productive than if you stop every so often. Taking a 15-minute break every hour is a good idea for most people.4.
Once your homework is done, you can check over it if you have extra time. Be sure to put it safely away in your backpack—there’s nothing worse than having a completed assignment that you can’t find the next morning or that gets ruined by a careless brother or sister. 5.Now you’re free to hang out.A. Luckily, you can do a few things to do less homework.
B. Homework is a major part of going to school.C. No one is expected to stay long, and people have very different learning styles.
D. If you need to, ask an adult for help or call or email a classmate for advice.
E. But if you’re really concentrating, wait until it's a good time to stop.F. And no teacher still believes that “chewed by the dog” line—even when it's true!
G. When you start your homework, deal with the hardest tasks first.

Why do some parents tend to hold back their disabled children from experiencing life? Even when they are grown, the parents will not allow certain things to happen. It's true that they do have a certain amount of responsibility in protecting their severely disabled adult child, but at what point do they become overly protective?
Parents want to create a safe haven, a place where they know that nothing bad will happen to their beloved child. This seems to be a respectable and notable act in caring for a person with a disability, but it can have a side effect. When protecting their child from suspected hardships, not wanting anything bad to happen to them, they very well may be preventing good things from happening to them.
In life we all make mistakes, it is how we are able to grow and strengthen our character. Parents may feel that in certain instances their child will get hurt or mistreated in some way, so they build walls in their own minds convincing themselves of the need to shelter. However, the disabled, yes even the “severely disabled” deserve to make personal mistakes as well. Even more, they have the right to succeed.
Parents should do everything and anything within their power to see their disabled children lead a somewhat “normal” life. Parents should help their children, not hold them down. This could make them think they are unworthy and that their parents do not believe in them.
Whatever it may be, let them at least try. If they want to attend college, so be it. Parents should find out all they can, and be involved in every detail. Get to know the aides, experience it with them. If they want to dare and someday marry, so be it. Don't shut them out and form bad or critical opinions about them just because you are afraid. Unite as a family and make it work.
1.What side effect will it have when the parents overprotect their disabled children?
A. Their children will never grow up in the future.
B. Their children will find no shelter when they grow up.
C. Their children will become less confident when facing troubles.
D. Their children will less likely meet with good things.
2.What attitude does the author hold towards the parents who overprotect their disabled children?
A. Supportive. B. Objective. C. Critical. D. Uninterested.
3.The suggestions in the last paragraph imply that ________.
A. parents should be a bridge, not a brick wall
B. parents should act as their children’s best friends
C. parents should encourage their children to get married
D. parents should live in harmony with their disabled children
4.What is the best title of this passage?
A. Living Within Parents’ Power
B. Letting Your Disabled Child Succeed
C. Getting out of a Brick Wall in Their Life
D. Helping Your Disabled Child out of Trouble
