You need, then, not only to learn and understand, but also to practice!
Here are a few suggestions on effective practice/study techniques.
1.Make your mouth or hand do what your mind is learning.Study out loud.Do go to the lab and work on the tapes.Study with a friend, and, thus, participate in speaking and listening.Try to write sentences or a short paragraph using the skills you have practiced with your own lips.
2.Study day-by-day.You cannot get by in a foreign language course by cramming (临时抱佛脚) at the last minute.You may be able to “learn” vocabulary items that way, but you cannot teach your mouth to use them in sentences.
3.Sometimes go back and review “old”topics and vocabulary.Language learning is cumulative (累积的).You learn new skills on the basis of old ones.The more you “recycle”familiar information and skills, the better you will be able to take in new ones.
4.Don’t be afraid to make mistakes.Self-consciousness (害羞) can be a strong barrier to learning a language.Perhaps part of the reason small children readily learn languages is that they are not afraid of making mistakes.

There is no shortage of tipsters around offering "get-rich-quick" opportunities. But if you are a serious private investor， leave the Las Vegas mentality （19）________ those with money to fritter. The serious investor needs a "proper portfolio" —— a well —— planned selection of investments， （20）________ a definite structure and a clear aim. （21） exactly how does a newcomer to the stock market go about achieving that？
Well， if you go to five reputable stock brokers and ask them what you should （22）your money， you"re likely to get five different answers even if you give all the relevant information about your age， family， finances and what you want from your investments. Moral？ There is no one right way to structure a portfolio. （23） ________ there are undoubtedly some wrong ways， and you can be sure that （24） of our five advisers would have suggested （25 ）________all （or perhaps any） of your money into Periwigs.
So what should you do？ We"ll assume that you have （26）________out the basics —— like mortgages， pensions， insurance and {27）________ to sufficient cash reserves. You should then establish your own individual aims. These are partly a matter of personal circumstances， partly a matter of psychology.
For instance， if you are older you have less time to recover from any major losses， and you may well wish to （28） ________your pension income. So preserving your capital and generating extra income are your main 15 priorities. In this case， you"d probably construct a portfolio with some shares （but not high risk ones）， along with gifts， cash deposits， and perhaps convertibles （29） ________the income shares of split capital investment trusts. If you are younger， and in a solid financial position， you may decide to take an （30） ________ approach but only if you"re blessed with a sanguine disposition and won"t （31） sleepless nights over share prices. If you recognize yourself in this description， you might include a couple of heady growth stocks in your 20 portfolio， alongside your more pedestrian investments. Once you have decided （32） your investment aims， you can then decide （33） ________ to put your money. The golden role here is to spread your risk —— if you put all of your money into Periwigs International， you"re setting yourself up as a hostage of fortune.
"Periwigs" is the name of a fictitious company.
