新学期英语教学计划7篇

新学期英语教学计划7篇新学期英语教学计划篇1一、早自习对学生的影响很大，如果能合理应用，可以对学生起到很大的帮助。

所以接下来的这个学期，我会尽量早起，合理安排每个早自习，与学生共同奋斗。

二、对于作业，我尽量做到每天一练，试卷全批全改，并在每次考试后及时统计分析，掌握学生的学习情况，并逐一分析错误原因。

三、教学方面，我会紧跟备课组的安排，抓进度，抓质量。

分阶段有重点地对学生进行操练。

具体措施如下：1、3月份即将迎来第二次高考听力，在1-4周，我会紧抓听力练习，让学生养成良好的听力习惯，并对学生较弱的方面进行强化训练。

2、高考阅读理解和完形填空占了很大的比例，而学生在这方面也是最弱的，所以平时要加强学生阅读完形的'训练，每天两篇阅读一篇完型，并及时校对。

3、写作是学生的另一薄弱环节，而写作的提高也是长年累月积累的结果。

所以平时课堂练习中要注重学生的写作能力，从单词，词组，单句，段落，到文章，一步一步打好学生的写作基础。

然后再分专题地对学生进行专门的写作训练，每两周一篇，并在早自习期间逐一面批，指出其错误，并让其自己改正以避免下次重犯。

4、对于高三的学生来说，考试是必要的，也是有效的检测他们阶段学习效率的最直接的办法。

在每个单元复习之后，我会进行单元测试，每个模块结束后，进行模块复习考试，以此来巩固学生平日所学。

总之，我会尽努力与学生共同进退!新学期英语教学计划篇2沐浴着金秋九月的金色阳光，我们迎来了临沂六中北校区的七年级新生。

他们朝气蓬勃，他们积极进取，面对新的校园，新的老师，新的同学，他们充满好奇，充满强烈的求知欲望。

为了能让他们在崭新的环境里，更好更快地发展，及早适应充实紧张的初中生活，根据学校统一部署，制定本学期的教学工作计划。

一、班级现状分析本学期我担任七年级九、十班的班主任。

七年级九班由57位学生组成，25位女生，32位男生。

七年级十班由56位同学组成，21位女生，35位男生。

学生来自各个不同的学校，有的来自实验小学，有的来自周边社区学校，有些来自县城或乡镇学校。

第二学期八年级英语教学工作计划(7篇)

第二学期八年级英语教学工作计划（7篇）学期英语教学计划篇一本学期非常短，除去节假日，大约只有十五周的在校时间，期中考试、期末考试和两次月考还要占去近两周的时间。

英语共有十二个单元，这样算下来每个周必须完成一个单元，还有自主课程、配套练习、阅读教程、单元检测需要处理。

任务特别艰巨，要想赶上进度，又不让学生掉队，需要老师合理安排时间，提高课堂效率。

1、认真备课。

将先周备课落到实处，将教材进行合理有效的整合，缩短教材学习时间，每个单元的教学任务必须在四节课内完成。

由于上个学期在语音学习上下了很大的'功夫，大部分学生拼读单词已不成问题，再加上寒假期间对预习要求比较细致，因此初步打算每节新课单词学习时间最多五分钟。

2、加强学生的预习指导。

要想加快学习进度，首先要求学生做好课前预习，尤其是单词、词组和课文的语音预习。

3、强化听写和书面表达。

将两个作业本分别设为听写本和作文本。

几乎每节课前都要听写上节课学过的内容，包括单词、词组和句子。

老师一定要先备好听写的内容，以免课上浪费时间。

每个单元至少写一次有效作文，写作文前一定要明确写作要求，并给学生留有充足的考虑时间，然后找部分学生口头给大家作示范，最后再让同学们写。

4、加强阅读训练。

如今的中考和高考，阅读占的比重最大，因此除了基础知识，提高学生的阅读能力是重中之重，要充分利用好阅读教程。

5、及时进行作业反馈。

将作业和单元检测中出错较多的地方及时反馈给同学们，以免时间长了容易遗忘。

总之，本学期时间短任务重，这就要求老师课前认真备课、课上提高效率、课下抓好落实，还要边学习边复习。

争取老师教的带劲，学生学的不累。

初二英语的教学计划篇二新学年已经开始，为使英语教学工作能有条不紊的进行，为今后工作中能取得更好的成绩。

特制定如下计划：一、指导思想。

坚持党的领导方针政策。

坚决拥护中国共产党的领导。

在英语学科教学活动中，面向全体学生，实施素质教育，减轻学生的课业负担。

在教学过程中进行专题研究，通过听，说，读，写诸方面的训练，使学生获得基础知识和实际交际能力，培养学生初步运用英语的'能力，激发学生学习英语的兴趣，养成良好的学习和生活习惯，为进一步学习打好基础，发展学生的思维能力和自学能力。

elongation value in Table 1.6.2Resistivity —The electrical resistivity of each of the four specimens shall conform to the requirements of 5.2.Failure to meet these requirements shall constitute failure to meet the resistivity conformance criterion.6.3Dimensions —The dimensions of the ﬁrst sample (Table 2)shall conform to the requirements of 5.3.If there are no failures,the lot conforms to this requirement.If there are failures,but the number of these do not exceed the allowable defect number,c 2(Table 2),for the respective number of units in the sample,a second sample equal to n 2shall be taken and the total defects of the n plus n 2units shall not exceed the allowable defect number,c 2.Failure to meet this requirement shall constitute failure to meet the dimensional conformance criterion.6.4Continuity of Coating —The continuity of the coating of each of the eight specimens shall conform to the requirements of 5.4.Failure of more than two specimens shall constitute failure to meet the continuity criterion.If not more than two specimens fail to meet the continuity criteria,eight additional specimens from the lot shall be tested,all of which shall conform to the continuity criteria.However,any individual production unit,the specimen from which failed to meet the continuity criteria,shall be rejected.6.5Weight of Coating —The weight of coating of each of the four specimens shall conform to the requirements of 5.5.Failure of more than one specimen shall constitute failure tomeet the weight criteria.If only one specimen fails to meet the weight criteria,four additional specimens from the lot shall be tested,all of which shall conform to the weight criterion.However,any individual production unit,the specimen from which failed the weight criteria,shall be rejected.6.6Packaging —Conformance to the packaging require-ments speciﬁed by the purchaser shall be determined in accordance with Table 3.The number of units in the sample showing nonconformance to the requirements shall not exceed the allowable defect number,c ,in Table 3.Failure to meet this requirement shall constitute failure to meet the packaging conformance criterion.7.Density7.1For the purpose of calculating weights,cross-sections,etc.,the density of the copper shall be taken as 8.89g/cm 3(0.32117lb/in.3)at 20°C (Explanatory Note 5).The density of silver shall be taken as 10.5g/cm 3(0.1mil)(0.37933lb/in.3).8.Test Methods8.1Tensile Strength and Elongation :8.1.1No test for tensile strength shall be required.8.1.2The elongation of wire whose nominal diameter is larger than 0.0808in.(2.052mm)in diameter shall be determined as the permanent increase in length,expressed in percent of the original length,due to the breaking of the wire in tension,measured between gage marks placed originally 10in.(254mm)apart upon the test specimen (Explanatory Note 7).The elongation of wire whose nominal diameter is 0.0808in.and under may be determined as described above or by measurements made between the jaws of the testing machine.When the latter method is used,the zero length shall be the distance between the jaws at the start of the tension test and be as near 10in.as practicable,and the ﬁnal length shall be the distance between the jaws at the time of rupture.The fracture shall be between gage marks,in the case of specimens so marked,or between the jaws of the testing machine and not closer than 1in.(25.4mm)to either gage mark or either jaw.8.2Resistivity —The electrical resistivity of the material shall be determined in accordance with Test Method B 193(Explanatory Note 8).The purchaser may accept certiﬁcation that the wire was drawn from rod stock meeting the Interna-tional Standard for Annealed Copper in lieu of resistivity tests on the ﬁnished wire.TABLE 2Sampling for Dimensional Measurements and Surface FinishNumber of Unitsin LotFirst SampleSecond SampleAllowable Number of Defects in Both Samplec 2Number of Units in Sample,n 1Allowable

about6in.(152mm).They shall be tagged or marked to correspond with the coil,spool,or reel from which they were cut.8.4.1.2Treatment of Specimens—Thoroughly clean the specimens by immersion in a suitable organic solvent such as benzene,ether,or trichloroethylene for at least3min;then remove and wipe dry with a clean,soft cloth(Warning:See Explanatory Note2).Keep the specimens thus cleaned wrapped in a clean,dry cloth until tested.Do not handle that part of the specimen to be immersed in the testsolution.Take care to avoid abrasion by the cut ends.8.4.2Special Solutions:8.4.2.1Sodium Polysulﬁde Solution(sp gr1.142)—Make a concentrated solution by dissolving sodium sulﬁde crystals (cp)in distilled water until the solution is saturated at about 21°C,and adding sufficientﬂowers of sulfur(in excess of250 g/L of solution)to provide complete saturation,as shown by the presence in the solution of an excess of sulfur after the solution has been allowed to stand for at least24h.Make the test solution by diluting a portion of the concentrated solution with distilled water to a speciﬁc gravity of1.142at15.6°C.The sodium polysulﬁde test solution should have sufficient strength to blacken thoroughly a piece of clean uncoated copper wire in 5s.A portion of the test solution used for testing samples shall not be considered to be exhausted until it fails to blacken a piece of clean copper as described(Explanatory Note9): 8.4.2.2Hydrochloric Acid Solution(sp gr1.088)—Dilute commercial HCl(sp gr1.12)with distilled water to a speciﬁc gravity of1.088measured at15.6°C.A portion of the HCl solution having a volume of180mL shall be considered exhausted if it fails to remove within15s the discoloration of the silver due to the polysulﬁde immersion.8.4.3Procedure:8.4.3.1Immersion in Polysulﬁde Solution—Immerse a length of at least41⁄2in.(114mm)from each of the clean specimens for30s in the sodium polysulﬁde solution,de-scribed in8.4.2.1,maintained at a temperature between15.6 and21°C.8.4.3.2Washing—After the immersion,thoroughly wash the specimens in clean water and wipe dry with a clean,soft cloth.8.4.3.3Immersion in Hydrochloric Acid—After washing, immediately immerse the specimen15s in the HCl solution described in8.4.2.2,thoroughly wash in clean water,and wipe dry with a clean,soft cloth.8.4.3.4Examination of Specimens—After immersion and washing examine the specimens to ascertain if copper exposed through openings in the silver coating has been blackened by action of the sodium polysulﬁde.Examine the specimen with the unaided eye(normal spectacles excepted)against a white background.The specimens shall be considered to have failed if,by such blackening exposed copper is revealed.No attention shall be paid to blackening within0.5in.(12.7mm)of the cut end.8.5Weight of Coating—Conformance to the weight require-ment for various classes and diameters of wire is best deter-mined by using test equipment that is speciﬁcally designed for this purpose.These devices offer superior accuracy while performing the measurement in a variety of manners.N OTE2—The accuracy of the testing is reliant upon adherence to the procedures for testing that have been developed by the manufacturers as their standard test regimen.There are thickness testing machines available that can be used to perform this measurement.The use of these devices should be at the mutual agreement of the manufacturer and the purchaser.8.6Finish—Surface-ﬁnish inspection shall be made with the unaided eye(normal spectacles excepted).9.Inspection9.1General(Explanatory Note5)—All tests and inspec-tions shall be made at the place of manufacture unless otherwise agreed upon between the manufacturer and the purchaser at the time of purchase.The manufacturer shall afford the inspector representing the purchaser all reasonable facilities to satisfy him that the material is being furnished in accordance with this speciﬁcation.9.1.1Unless otherwise agreed by the manufacturer and the purchaser,conformance of the wire to the various requirements listed in Section5shall be determined on samples taken from each lot of wire presented for acceptance.9.1.2The manufacturer shall,if requested prior to inspec-tion,certify that all wire in the lot was made under such conditions that the product as a whole conforms to the requirements of this speciﬁcation as determined by regularly made and recorded tests.9.2Terms Applying to Inspection:9.2.1Lot—A lot is any amount of wire of one type and size presented for acceptance at one time,such amount,however, not to exceed10000lb(4540kg)(Explanatory Note10). 9.2.2Sample—A sample is a quantity of production units (coils,reels,etc.)selected at random from the lot for the purpose of determining conformance of the lot to the require-ments of this speciﬁcation.TABLE3Sampling for Packaging InspectionNumber of Unitsin Lot Number ofUnits

eight production units.From each unit,one test specimen of sufficient length shall be removed for the perfor-mance of the required test.9.2.4.2For dimensional measurements and surfaceﬁnish, the samples shall consist of a quantity of production units shown in Table2under the heading“First Sample.”9.2.4.3For packaging inspection(when speciﬁed by the purchaser at the time of placing the order),the sample shall consist of a quantity of production units shown in Table3. 10.Packaging and Package Marking10.1Package size shall be agreed upon by the manufacturer and the purchaser in the placing of individual orders(Explana-tory Note11).The wire shall be protected against damage in ordinary handling and shipping.11.Keywords11.1copper wire silver-coated;silver-coated annealed cop-per wire;silver-coated copper electrical equipment wire; silver-coated soft copper wireEXPLANATORY NOTESN OTE1—Silver coatings on copper wire provide for:(a)A barrier between the copper and insulation whose curing tempera-ture in the process of fabricating is too high for the use of tin-coated wires.(b)A low-contact resistance between the strands of outer conductors of coaxial conductors used in high-frequency circuits.(c)A lost radio-frequency resistance of conductors used in high-frequency circuits(skin effect).(d)Good solderability for high-temperature hook-up wires which prohibit the use of tin-coated wires due to high curing temperatures used in fabricating theﬁnished wire.N OTE2—Warning:Consideration shall be given to toxicity andﬂam-mability when selecting solvent cleaners.N OTE3—The values of the wire diameters in Table1are given to the nearest0.0001in.and correspond to the standard sizes given in Speciﬁ-cation B258.The use of gage numbers to specify wire sizes is not recognized in this speciﬁcation because of the possibility of confusion.An excellent discussion of wire gages and related subjects is contained in NBS Handbook100.6N OTE4—Whether the silver is applied by electroplating or by mechani-cal cladding,coatings less than40µin.(0.00004in.)in thickness will not pass the“Continuity of Coating”test.See Table1for thickness of coatings for the various classes of coating and wire sizes.N OTE5—Cumulative results secured on the product of a single manu-facturer,indicating continued conformance to the criteria,are necessary to ensure an over-all product meeting the requirements of this speciﬁcation. The sample size and conformance criteria given for the various charac-teristics are applicable only to lots produced under these conditions.N OTE6—The value of density of copper is in accordance with the International Annealed Copper Standard.The corresponding value at0°C is8.90g/cm3(0.32150lb/in.3).N OTE7—In general,tested values of tensile strength are increased and tested values of elongation are reduced with increase of speed of the moving head of the testing machine in the tension testing of copper wire. In the case of test on soft or annealed copper wire,however,the effects of speed of testing are not pronounced.Tests of soft wire made at speeds of moving head which under no-load conditions are not greater than12 in./min do not alter theﬁnal results of tensile strength and elongation determinations to any practical extent.N OTE8—Resistivity units are based on the International Annealed Copper Standard(IACS)adopted by IEC in1913,which is1⁄58V·mm2/m at20°C for100%conductivity.The value of0.017241V·mm2/m and the value of0.15328V·g/m2at20°C are respectively the international equivalent of volume and weight resistivity of annealed copper equal(to 5signiﬁcantﬁgures)to100%conductivity.The latter term means that a copper wire1m in length and weighing1g would have a resistance of 0.15328V.This is equivalent to a resistivity value of875.20V·lb/mile2, which signiﬁes the resistance of a copper wire1mile in length weighing 1lb.It is also equivalent,for example,to1.7241µV/cm of length of a copper bar1cm2in cross section.A complete discussion of this subject is contained in NBS Handbook100of the National Institute of Standards and Technology.6The use ofﬁve signiﬁcantﬁgures in expressing resistivity does not imply the need for greater accuracy of measurement than that speciﬁed in Test Method B193.The use ofﬁve signiﬁcantﬁgures is required for reasonably accurate reversible conversion from one set of resistivity units to another.The equivalent resistivity values in Table4 were derived from the fundamental IEC value(1⁄58V·mm2/m)computed to7signiﬁcantﬁgures and then rounded to5signiﬁcantﬁgures.N OTE9—It is important that the polysulﬁde solution be of a proper composition and strength at the time of test.A solution that is not saturated with sulfur or that has been made from decomposed sodium sulﬁde crystals may give a false indication of failure.Therefore,the requirement that the solution be tested by observing its blackening effect on a bright copper wire is signiﬁcant.Signiﬁcant also is the requirement that the solution be saturated with sulfur by allowing the solution to stand at least 24h after preparation.Attention is called also to the necessity for the use of sodium sulﬁde that has not deteriorated through exposure to air;and if exposure has occurred,the crystals should be tested for purity.The “Standard Reagents Tests”of the American Chemical Society are useful in this connection.N OTE10—A lot should comprise material taken from a product regularly meeting the requirements of this speciﬁcation.Inspection of individual lots of less than500lb of wire cannot be justiﬁed economically. For small lots of500lb or less,the purchaser may agree to the manufacturer’s regular inspection of the product as a whole as evidence of acceptability of such small lots.N OTE11—Attention is called to the desirability for agreement between the manufacturer and the purchaser on package sizes that will be6Available from the National Technical Information Service,5285Port Royal Road,Springﬁeld,V A22161.TABLE4Resistivity Relations Conductivity at20°C%100.00 V·lb/mile2875.20V·g/m20.15328V·cmil/ft10.371V·mm2/m0.017241µV·in.0.67879µV·cm1.7241sufficiently large and yet not so heavy or bulky that the wire may likely be damaged in handling.N OTE 12—Principle of Operation of the Electronic Thickness Tester —The unit operates by anodically deplating a small surface area of the specimen in a cell containing the test solution.The cell serves as cathode and the piece to be tested is the anode.At the start of the test and until the base metal is exposed,a voltage characteristic of the plating exists across the cell;when all the plating has been removed from the test spot,this voltage changes sharply and assumes a new value which is now characteristic of the base metal.This rapid voltage change is the“end point”of the test,and is ampliﬁed and caused to operate a relay which turns off the instrument.The time required to dissolve the plating on the test spot proportional to the thickness of the deposit;by correlating the area of the test spot with the current used to strip the plating,the counter is made to read directly in units of thickness.Essentially,therefore,the electronic thickness tester embodies a min-iature reverse-current plating cell in which the piece to be tested is theanode and the cell itself is the cathode.The test solution used is speciﬁcally designed to give 100%anodic current efficiency.It does not attack the plating unless current is ﬂowing through the test cell.The anode efficiency is further maintained by providing agitation of the solution in the test cell.N OTE 13—The equation given for the weight of the silver on the wire is for most purposes sufficiently accurate.However,in the case of heavy coatings the results obtained by the use of this equation will indicate a slightly higher percent weight than is actually present.The more correct equation for all cases based on a density of 10.5g/cm 3for silver and 8.89g/cm 3for copper is as follows:Silver %5472.43/[1.72431d /t 1t /~d 2t !#where:d =overall wire diameter,in.,and t =thickness of plate,in.SUPPLEMENTARY REQUIREMENTSThe following supplementary requirements shall apply only when speciﬁed by the purchaser in the inquiry,contract,or order,for agencies of the ernment.S1.Referenced DocumentS1.1The following documents form a part of this speciﬁca-tion to the extent speciﬁed herein.Unless otherwise speciﬁed,the issues of these documents shall be those listed in the issue of the Department of Defense Index of Speciﬁcations and Standards (DODISS)and supplement thereto,cited in the solicitation.S1.2Military Speciﬁcation:7MIL-C-12000Cable,Cord,and Wire,Electric;Packaging of S2.InspectionS2.1The government shall have the right to perform any of the inspections and tests set forth in this speciﬁcation when such tests are deemed necessary to ensure that the material conforms to the prescribed requirements.S3.PackagingS3.1Packaging shall be in accordance with MIL-C-12000.APPENDIX(Nonmandatory Information)X1.DETERMINATION OF THE WEIGHT OF SILVER ON SILVER-COATEDCOPPER WIREMETHOD A—ELECTRONIC DETERMINATION(EXPLANATORY NOTE 12)X1.1Apparatus and ReagentX1.1.1Electronic Thickness Tester with Accessory Unit“WT.”8X1.1.2Solution R-48.8X1.2Limitations of Method AX1.2.1This method is suitable for the determination of the thickness of coatings as follows:Wire Size Sample Length,in.0.0720to 0.02400.500.0239to 0.0115 1.000.0114to 0.0058 2.000.0057to 0.00314.007Available from Standardization Documents Order Desk,Bldg.4Section D,700Robbins Ave.,Philadelphia,PA 19111-5094,Attn:NPODS.8The above named apparatus and reagent is the product of Kocour Company,4800So.St.Louis Ave.,Chicago,IL60632.。
