Bruce got on the bus early in the morning. He was going to the next town to visit one of his friends. He had got up very early, and he felt tired. Soon he fell asleep. A short while later, he woke up in the middle of a dream. In his dream, he was in a busy street. People were pushing him hard and pulling at his clothes. As he woke up, he found that it wasn＇t only a dream.Somebody was really pulling at his coat pocket.     

A new mutation （1062 del 16） of iduronate-2-sulfatase gene from a Chinese patient with Hunter syndrome

Objective: To identify the mutations of iduronate-2-sulfatase (IDS) gene, to reveal its mutation features, and to establish a basis for genetic counseling and prenatal gene diagnosis of Hunter syndrome. Methods: Urine glycosaminoglycans (GAGs) assay, PCR and DNA sequencing were performed to detect mutation of IDS gene of the patient and his parents. Results: The result showed that the patient was: DS( ), HS( ), KS(-), CS(-), and that both of his parents were negative. A frame-shift deletion mutation (1062 del 16) was identified in exon 7 of the patient's IDS gene. His parents' genotypes were normal. Conclusion:The patient's mutation was not inherited by his parents but a novel one. The mutation probably altered the primary structure and tertiary structure of IDS enzyme protein remarkably and lowered the activity of IDS enzyme greatly. Therefore it is supposed to be the direct cause of the disorder.     

言语行为

The theory of Speech Act is one which analyses the role of utterancesin relation to the behaviour of speaker and hearer in interpersonal comm-unication.It was originally put forward by John Langs haw Austin.a pro-fossor philosphy at Oxford University.In 1955,he gave a serics of lectu-res at Harvard University in U.S.A,and after his death,the written s-cripts of his lectures were published(1962)with the title How to Do T-hings with words.The theory aroused wide interests among the Linguisticphilosophers.Late,Searle and Grice,two ther philosophers made furthercontributions to the theory.

The Death of Aestheticism

As a trend of thought in literature and art,aestheticism rose suddenly at the end of the 19th century and withered away soon.It was just like a flash in the world of literature and art.One of the initiators,Oscar Wilde,has been noticed with great attention by the critics.Wilde earnestly practiced the aestheticism he advocated.Some of his acts were cast aside by the moral in his time,which at last led to his death in a strange land.

A Teacher of the Old School

My grandfather was a teacher. He was the headteacher of a school for boys between the ages of thirteen and eighteen. I know that he was a kind and gentle man at heart, because when I was young(and he was old), he gave me presents, and sat me on his knee, and told me stories. But I believe the boys at his school were afraid of him.

A Critique of Ali Shehadeh’s Non-native Speakers’Production of Modified Comprehensible Output and Second Language Learning

This study examined the NNSs’ ability of modifying their interlanguage utterances in modified comprehensible output to give response to other-initiation and self-initiation,which was studied in both NS-NNS and NNS-NNS interactions.It was the qualitative study by using two different tasks which were picture-dictation task and opinion-exchange task to collect the data.There were 32 participants whose age ranged of 22 to 37.The author proposed two hypotheses based on his expectation that NNS-NNS interactions would provide more opportunities for NNS participants to give comprehensible output for other-initiated clarification requests and self-initiated clarification attempts than NS-NNS interactions.The author was good at using numbers to illustrate and describe the data in his writing.

Something about Joe Hill Joe Hill was born in Sweden and went to the United States in 1901. He took part in the workers’ movement and helped to form trade unions (职业联盟). He wrote songs and sang them at union meetings to call on workers. Many of his songs became so popular (流行) that the bosses and the police began to take notice of him.

难忘的情人节礼物

The traditional holidays in our house when I was a child were spent timing elaborate (精致的) meals around football games. My father tried to make pleasant chitchal(聊天) and eat as much as he could during half time. At Christmas he found time to have a cup or two of holiday cheer and don (戴上) his holly-shaped (形冬青叶状的) bow tie. But he didn't truly shine until Valentine's Day. I don't know whether it was because work at the office slowed during February or because the football season was over. But Valentine' s Day was the time my father chose to show his love for the special people in

Isolation and physiological characteristics of a premature senescence mutant in rice （Oryza sativa L.）

A rice pse(t) (premature senescence, tentatively) mutant line, was isolated from 4500 independent T-DNA inserted transgenic lines. The symptoms of premature senescence appeared more severely than those of the control plants (Zhonghua 11,japonica) at the last development stage. To characterize the mutant and provide basic information on the candidate genes by mapping to a physical region of 220-kb, experiments were carried out in two phytotrons under controlled temperature of 24 ℃ and28 ℃, respectively. The content of chlorophyll, soluble protein and MDA (malondialdehyde), net photosynthesis, the antioxidant enzyme activities of SOD (superoxide dismuase) (EC 1.15.1.1) and POD (peroxidase) (EC 1.11.1.7) and the peptidase activities of leaves were measured from top to bottom according to the leaf positions at the flowering stage. Compared with the control plant,the mutant showed the following characteristics: (1) Higher net photosynthesis rate (Pn) appeared in the 1 st and 2nd leaves, contents of chlorophyll and soluble protein were also higher in the 1 st leaf; (2) The activities of SOD, POD and peptidase were higher according to the leaf position from top to bottom; (3) The symptom of premature senescence was accelerated in the mutant at 28℃treatment. The MDA content and the SOD and POD activities between the 24 ℃ and 28 ℃ treatment mutants were not significantly different. Content of chlorophyll and soluble protein of leaves mutant decreased rapidly at 28 ℃ treatment. The results show that pse(t) is sensitive to high temperature. The probable function of PSE(T) is discussed.
