阅读下面的文章，根据文章内容，完成相应的选择题。

FOOD SAFETY

A question that often troubles food companies is how to control problems like rats and insects without harming the food. Pest control experts say poisons should never be used where they may enter food. They say the first line of defense against pests is to clean the places where the food is handled or stored.

Floors, food preparation surfaces and tools can be disinfected with chemicals like chlorine, iodine or bromine. Food containers should be stored about half a meter off the ground and about half a meter away from any walls. Storage areas should be kept dry and clean.

Containers for raw materials such as rice, wheat, etc. should be kept closed and clean. Any foodstuff split during delivery or handling should be cleared up both inside and outside the building. Pests enter a building from the outside, so pay attention to outer walls. Small stones can be used to cover the ground and block the growth of plants and the grass should be kept short to deny pests a place to live.

Check that doors and windows are completely closed. Also any hole that might allow pests to enter a building should be filled. Rats can enter through a hole the size of a coin. A mouse can pass through a hole half that size.

Supervisors should make a list of pest control measures to be taken by employees. This will aid the efforts and also help prepare for any inspections. In most countries, there is a food and drug administration bureau, or some agency with a similar name, which enforces rules nationwide, responsible for rules about the use of pesticides, etc. However, businesses where food is stored, prepared or sold must also follow state and local health laws. Most of these governmental departments or bureaus have their websites with information about food safety policies and other issues. People can easily access the information.

听力原文：Some banks offer other types of loans repayable by monthly installments, such as

听力原文： Some banks offer other types of loans repayable by monthly installments, such as business development loans, house improvement loans, and farm development loans. These may be either secured or unsecured. Secured loans attract a slightly lower rate of interest than unsecured loans. Some banks offer revolving credit schemes. These normally involve loans repayable by regular monthly installments, but they differ from other loans repayable by installments in two respects. First, the borrower need not take up the full amount of the loan at the outset. Secondly, as his repayments reduce his indebtedness, he can "top up" his loan by borrowing more, provided that the total debt outstanding does not exceed his agreed credit limit. In 1967 some banks introduced a new form. of account called a "budget account". The object is to allow personal customers to spread the incidence of normal personal and household expenditure.

24. Which of the following loans is not repaid by installments？

25.Which of the following loans would attract a lower rate of interest？

26.How does a borrower "top up" his loan？

27.What is the objective of introduction of the budget account？

(24)

A．Business development loans.

B．House improvement loans.

C．Farm development loans.

D．Overdrafts.

第7题

There are many ways of dealing with offenders that do not involve the payment of money. On

e is probation, a system that takes many different forms in different jurisdictions but that essentially involves the suspension of sentence on the of fender subject to the condition that he is supervised while living in the community by a probation officer and possibly agrees to comply with such other requirements as the court many think appropriate. Usually, if the offender complies with the probation officer and commits no further offense while it is in force, no other penalty is imposed, but if he breaks the requirement of the order or commits another offense, he can be brought back before the court and punished for the original offense as well as the later one. In many U. S. states. probation is combined with a suspended sentence, so that the sentence the offender will have to serve if he breaks the order is fixed in advance; in England the sentence is not fixed in advance, and the court has complete discretion if there is a breach to sentence the offender for the original crime in light of his tater behaviour. English law allows suspended sentence of of imprisonment for a specified period (not more than two years), on condition that tile offender commit no further offense during the period of suspension. This is different from a probation order, as no supervision is required and no other conditions may be included in the order.

Other alternatives to prison are based on the idea of preventing an offender from committing further offenses, without necessarily confining him in a prison. The most familiar power of this kind is that of disqualifying an offender from driving a motor vehicle or from holding a driver's license. This power is available under the laws of most countries to deal with those offenders who either commit serious driving offenses, such as driving while intoxicated, or who commit repeated but less serious offenses, such as speeding. In many countries there exists a system in which the offender is awarded a number of points each time he commits a motoring offense; when the number of points accumulated reaches a certain figure, he is automatically disqualified for a specified period. Some countries allow courts to disqualify from driving those offenders who have used motor vehicles in commission of the crime for which they are being sentenced, with the aim of hindering the offender from committing further such offenses. Although attractive in the abstract, this seldom works well in practice, as the absence of a driver’s license may well prevent an offender from finding work after release from prison; as a result he may be likely to commit further crimes. Other forms of disqualification may be imposed on offenders convicted of particular types of crimes: a fraudulent company director may be disqualified from being involved in the direction of a company, a corrupt politician may be disqualified from holding public office, or a parent who sexually abuses his children may be deprived of parental authority over them.

The first paragraph is primarily about ______.

A．ways of dealing with offenders

B．the probation system

C．the suspension of sentence on the offender

D．the suspended sentence of imprisonment
